Respiratory Medicine Lexicon

Respiratory Medicine Lexicon:
Here's a list of all medicines currently used to treat lung diseases, or medicines we RTs should be familiar with, including off label use.  For old respiratory medicines visit my Respiratory Medicine Archive (coming soon).

(Not familiar with hospital abbreviations? click here)

Fast Acting Bronchodilators (Rescue Medicine):

1. Generic name: Albuterol, Salbutamol

Brand name: Proventil, Ventolin

Delivery devices:
  • SVN: o.5cc or 2.5 mg and usually comes in an amp with 0.3cc normal saline
  • MDI: (90 mcg/puff)
  • DPI: (200 mcg/cap)
Adult dose/frequency:
  • SVN: 0.5cc every 4-6 hours
  • MDI: 2 puffs every 4-6 hours (3-5 puffs are equivelent with SVN)
  • DPI: 1 puffs every 4-6 hours
Action: Onset 5 minutes, peaks in 30-60 minutes, duration is 3-8 hours

Diagnosis: Used for asthma, COPD,

Comments: Very mild side effects, may cause shakes or nervousness, rarely increases heart rate in patients with healthy heart, safe for all patients of all ages. Can be mixed with Atrovent and Pulmicort (although if you're taking the NBRC exam this is not true). Also safe for children and neonates at the adult dose, especially if given via blowby. Most commonly used beta adrenergic medicine. Low cost per dose. Studies show an MDI use properly with a spacer is equally as effective an an SVN. Studies also show (as you can read here) that Albuterol does increase mucociliary clearance, but studies also show this has no clinical effectiveness. This may also explain why doctors like to use Albuterol to increase sputum and pneumonia. The aerosolized particles are the right size to reach the larger airways (bronchioles) and to some extent the smaller airways, but too large to reach the 0.1 to 0.2 micron alveolar sacs. Despite contrary belief, this medicine does not treat inflammation in the airway nor in the alveolar sacs. It is specifically designed to connect with beta adrenergic receptors in on bronchiole muscles and cause them to relax, and in this way it can make it easier to patients to breathe rather quickly.

Comment #2: Can also be used to lower potassium, yet studies show a minimum dose of 5-20mg Albuterol run continuously over 20 minutes generates the most effect. For more on this, and for links to studies and AARC Guidelines, click here. If a doctor orders one treatment of 5cc Albuterol, you can either keep your mouth shut just to get done, or you can make him aware of the AARC guidelines for lowring Potassium with Albuterol

2. Generic name: Levalbuterol:
Brand name: Xopenex
Delivery Devices:
  • SVN: 0.31, 0.63 and 1.25 mg with 3cc normal saline in one amp
  • MDI: 650 mcg/puff
Adult dose and frequency:
  • SVN: 1.25 mg every 6-8 hours or three times a day (0.63 for less cardiac effect*)
  • MDI: 2 puffs every 4-6 hours
Action: Onset 15 minutes, peaks in 1-1.5 hours, duration is 1-6 hours (medium)

Comments: Minimal side effects. Studies are inconclusive, yet some theorize *that this medicine has fewer side effects than Albuterol. Some also say it works better than Albuterol. Most experts now deny both these claims. However, it generally works as well as Albuterol in treating bronchospasm. It is safe for all populations at all doses. May actually some day be used in place of Albuterol, but at the present time it has a high cost per dose. The S isomer in Albuterol is believed to cause bronchospasm if used long term, and therefore lebalbuterol only contains the R isomer.

3. Generic name: Racemic Epinepherine*

Brand name: Vaponepherine, Micronepherine

Delivery Device: SVN 2.25%

Adlt dose and frequency: 0.25 to 0.5 cc to 2.5 cc mixed with normal saline to be given as needed, although the most common dose is 0.5cc and is safe for adults and children.
Action: Onset is 3-5 minutes; Peaks in 5-20 minutes; Duration 0.5 to 2 hours (short)
Comments: Moderate risk of side effects that include shakiness, increased heart rate, palpitations, etc. Although the risk of side effects is much less than epinepherine. Generally used to relax throat muscles or to treat upper airway inflammation in diseases such as croup or post extubation. However it also is used to relieve bronchospasm. It can be used for asthmatics when Albuterol and Xopenex aren't working. Has been known to cause rebound edema. This medicine has an alpha effect that causes vasoconstriction and reduces blood flow and mucosal edema. Studies show it also reduces bronchial and tracheal secretions. Generally shows results in 30 minutes for croup and lasts up to 2 hours. Patients given racemic epinepherine may not be discharged to home unless they show no respiratory distress and no adverse side effects for three hours after therapy. May use in conjunction with dexamethasone (oral) or budesonide (aerosol) for best results.
4. Generic name: Epinepherine*

Brand name: Adrenaline

Delivery Device: SVN: 1% (1:100) 0.25 - 0.5cc prn mixed with 3cc normal saline

Adult dose and frequency: 0.25 to 0.5cc prn as needed to relieve bronchospasm; duration 1-3 hour. Considered a low dose to obtain beta effect.

Comments: Strong side effects. It's actually a vasopressor but I'm listing it here as a bronchodilator because in low doses it's often used as a bronchodilator. Generally not used in the hospital setting anymore for its bronchodilating effects unless all other options fail. Studies show that Albuterol used continuously is safer and works just as well or even better than epinepherine, and therefore epinipherine (epi) is generally only used as a last report to treat respiratory failure before intubation and ventilation. It used to be a front line medicine to treat asthma in the 1970s, and also had a longer lasting version called Susphrine. (Susphrine is no longer produced in the U.S.) It's also used to treat arrythmias such as ventricular tachycardia, ventricular fibrillation, asystole, and bradycardia (see epi under vasopressors below). It's also used in low doses to treat anaphylaxis.

Anticholinergic Bronchodilators: These are back door bronchodilators, knows to block the cholinergic effect and cause bronchdilation that way. These drugs work against the bronchoconstriction caused by the parasympathetic nervous system (decrease cyclic GMP). They block the cholinergic parasympathetic receptors.

1. Generic name: Ipatropium Bromide
Brand name: Atrovent

Delivery Device:
  • SVN: 0.2%
  • MDI: 18 mcg/puff
Adult dose and frequency:
  • SVN: 2.5 cc (unit dose) mixed with 3cc normal saline TID or QID.
  • MDI: 2-3 PUFFS TID or QID
Action: Onset is 15 minutes; Peak in 15-90 minutes; Duration is 4-6 hours long
  • When should Atrovent HFA be primed? Click here.
Comments: For maintenence therapy of bronchospasm in COPD; can cause dryness; should not be used in conjuntion with mucomyst; can be used for asthma only when other front line medicines don't work; studies show it improves lung function in COPD and severe asthma; studies show it may improve dyspnea in the emergency room setting, and is now commonly used in conjuntion with Albuterol in the emergency room for all COPD and asthma patients; also safe for kids; relatively mild side effects if any. Studies also link long term use of Atrovent with heart failure, so it may be safer to use Tiotropium Bromide, which has not been linked with heart failure.

2. Generic name: Tiotropium Bromide

Generic name: Spiriva

Delivery Device: DPI 18 mcg/puff

Adult dose: 1 puff per day

Action: Onset 30 minutes; peak 3 hours, duration 24 hours

Comments: Can cause dryness and paradoxical bronchospasm; has been shown to improve lung function in COPD, and is proven safer than Atrovent; Generally not used for asthma, although it can be used if other medicines don't work. This is the long acting version of anticholinergic bronchodilator.

3.  Generic name:  Aclidinium Bromide

Brand name:  unknown at present, possibly Genuair

Delivery device:  Genuair inhaler.  The inhaler has a built in feedback system to inform the patient if the medicine was used correctly.  It also has an anti double dosing mechanism and a dose counter. 

Adult dose:  1 puff twice a day

Comments:  It's a long acting anti cholinergic agent It is a medicine that has been sent for approval by the FDA, so it's currently not available on the shelves. Early studies show it improves exercise tolerence and lung function in COPD patients.  It appears to be similar to tiatropium bromice (Spiriva) except that it must be taken twice daily.  No studies have yet been conducted to compare tiatropium bromide with acclidinium bromide

4. Generic name: Oxitropium bromide

Brand name: Oxivent

Delivery device: MDI 100 mcg/ puff

Adult dose: 2 puffs every 8-12 hours

Action: similar to Atrovent

Comments: Not available in the U.S.

5. Generic name: Atropine
 Brand name: none

Delivery device: SVN aerosol

Adult dose: 0.05 mg/kg in 3 cc normal saline every 6-8 hours.

Action: Similar to Atrovent

Comments: No longer used considering Atrovent and Spiriva have fewer side effects, yet it is still available in hospitals as an option and that's why I list it here. It's also used to treat the cardiac arrythmia of bradycardia.

Long Acting Bronchodilators:

1. Generic name: Formeterol

Generic name: Foradil

Delivery device: DPI 25 mcg/ puff

Adult dose: 1 puff BID

Comments: Use only if inhaled steroids do not control COPD or asthma; the FDA recommends if you need Foradil for your asthma you should also be getting an inhaled corticosteroid with it, so generally Symbicort is a better option for asthmatics and COPD patients. Sometimes Foradil alone can be useful for COPD. Studies link Foradil with increased asthma deaths, although some experts contend this is not so much the medicine itself but that fact that some asthmatics rely to much on the medicine (perhaps even abuse it) as opposed to seeking help. So patients should be instructed to use this medicine as prescribed only, and not to over use it.

2. Generic name: Salmeterol
Brand name: Serevent

Delivery device:
  • MDI: 25 mcg/ puff (phased out)
  • DPI: 50 mcg/puff
Adult dose:
  • MDI: 2 puffs BID
  • DPI: 1 puff BID
Action: Onset in 10-20 minutes; peaks in 3 hours, duration is 12 hours
Technique: To learn how to use Serevent Discus, click here.

Comments: Use only if inhaled steroids do not control asthma; patients should seek treatment if symptoms worsen instead of over relying on this medicine. The FDA recommends if an asthmatic needs this medicine it should be used in conjunction with an inhaled corticosteroid (either with Flovent or Advair should be used) to treat both bronchospasm and chronic underlying inflammation that is generally present with asthma lungs.

Combination medicines:
1. Generic name: Ipatropium Bromide + Albuterol

Brand name: Duoneb SVN (Combivent MDI)

Delivery device:
  • SVN: 2.5 mg albuterol plus 0.5 mg ipatropium bromide with 3cc normal saline
  • MDI: 90 mcg albuterol plus 18 mcg ipatropium bromide
Adult dose:
  • SVN: Treatments TID or QID or as needed to relieve bronchospasm
  • MDI: 2 puffs TID or QID or as needed to relieve bronchospasm
Action: See Albuterol and Ipatropium bromide
Comments: See Albuterol and Ipatropium bromide
2. Generic name: Fluticasone + Salmeterol

Brand name: Advair

Adult dose: Fluticanasone = 100, 250, or 500; Salmeterol = 50 mcg; Comes with 60 capsules to last one month.

Action: See Salmeterol above and Fluticasone below

Comments: See Salmeterol above and Fluticasone below. Advair should be used when the benefits outweight the disadvantages. Generally, it has proven safe and very effective as a top line asthma treatment recommended by the asthma guidelines. Studies show it is safe to use as a top line asthma treatment, and is safe to use as I write in this post.

Technique: To learn how to use Advair Discus, click here.

3. Generic name: Budesonide + Formeterol

Brand name: Symbicort

Delivery device: Turbohaler

Adult dose:

Action: See Formeterol above and Budesonide below

Comments: In Europe the SMART program is available, which allows asthmatics to use up to 8 puffs of this medicine as needed through the day. The FDA has yet to legalize this in the U.S. For other notes, see Formeterol above and Budesonide Below. The medicine should not be used more often than prescribed by a doctor. Symbicort is also proven safe to use and is highly recommended as a top line treatment for asthma as I write about in this post.

Technique: To learn how to use the Turbohaler, click here.

3.  Generic name:  Mometasone furoate and formoterol fumarate dihydrate

Brand name Dulura

Comments:  A combination of Mometasone Furoate (the main ingredient of the inhaled steroid Asmanex available since 2005) and Formoterol Fumarate (main ingredient of the LABA, Foradil available since 2001 and also in Symbicort). Dulera is indicated for the treatment of asthma in ages 12 and above. It is an aerosol inhaler that has a digital dose counter and comes in two strengths. It is a controller inhaler that should be taken as two puffs twice daily. It should never be used to relieve symptoms.. Short acting reliever inhalers should also be on hand for use as needed.  Dulera is another alternative for treating asthma that fails to respond to medium or high dose inhaled steroids.

Corticosteroid inhalers: Used to reduce bronchial inflammation to control asthma, COPD; usually take 1-2 weeks to take full effect.

1. Generic name: Beclomethosone

Brand name: Qvar (Vanceril and Beclovent have been phased out)

Delivery device: MDI: 40 mcg/puff and 80 mcg puff

Adult dose: 2 puffs BID

Action: Varies

Technique: To learn proper use of Qvar with spacer, click here.

Comments: Have patient rinse mouth with water post treatment to prevent pharyngitis, oral candiditis (thrush). Studies show that Qvar might be better at reaching the smaller airways as compared to other inhaled corticosteroids, and it may be used in conjunction with another inhaled steroid in severe cases of asthma. I write about Qvar in this post.

2. Generic name: Budesonide

Brand name: Pulmicort

Delivery device:
  • DPI: 200cg/puff pulmicort turbohaler
  • SVN: 80 mcg/puff
Adult dose:
  • DPI: 1-3 puffs BID
  • SVN: 2 cc (unit dose with 3cc normal saline)
Action: Onset within 24 hours; duration varies

Comments: Pulmicort SVN advertised for children, especially those who have trouble with DPIs. The only reason adults should be prescribed Pulmicort SVN is if they have trouble with DPIs. DPI and MDI may be prescribed as preferred by physician and patient. Have patient rinse mouth after using to prevent thrush and other side effects. Studies show that nebulized budesonide is equally effective as dexamethosone in treating croup, allows for shorter hospital stays, and less use of epinepherine.

3. Generic name: Fluticasone propronate

Brand name: Flovent, Flovent Rotadisk

Delivery device:
  • MDI: 44, 110 and 220 mcg/ puff (phased out)
  • DPI: 50, 100, and 250 mcg/ puff
Action: Onset within 24 hours; duration 2-3 days


4. Generic name: Mometasone furoate
Brand name: Asmanex

Delivery device: DPI: Turbohaler (powder) 110 mcg delivers 100 mcg of the medicine; 22 mcg delivers 200 mcg of the medicine; the 110 and 220 mcg doses come with 30 capsuls to last one month; there is also a 440 mcg dose as well.

Adult dose: Once daily in the evening, usually the 120 dos


Comments: The 110 dose can be used for children ages 4-11; the 440 dose can be used for those with severe asthma or severe COPD who require higher doses of inhaled corticosteroids to control pulmonary inflammation. Those using the 440 dose may take it up to twice a day if recommended by a physician. Patients must be encouraged to rinse their mouth out after therapy to prevent thrush and other side effects.

Systemic Corticosteroids: Used to reduce bronchial inflammation. They are anti-inflammatory, immunosuppresive agents (decrease sputum eosinophils) with direct bronchodilating effect. Because it's given systemically, the medicine works better for exacerbations of COPD and asthma or other pulmonary conditions. Patients will have to slowly be weaned off this medicine. Used for acute exacerbations only. Side effects may be severe. Can cause glucose to rise so glucose will need to be monitored, especially in patients with diabetes or the elderly. Can lead to adrenal suppression, cushing's syndrome (if used for long periods of time), osteoporosis, hypertension, oral candidiasis (thrush), and may effect the immune response and healing post operative. They must be used judiciously.

1. Generic name: Methylprednisolone

Brand name: Solu-Medrol

Comments: Given intravenously by IV or injection in hospital to patients who are in respiratory distress, and the underlying reason for the distress is believed to be inflammation of the air passages of the lungs (bronchospasm) or alveoli (pneumonia). Generally takes an hour or two to take effect. A patient generally cannot go home from the ER until this medicine takes effect and the patient is no longer in respiratory distress. If given for pneumonias caused by bacteria, it should be given in conjuntion with an antibiotic. Should also be given in conjunction with a bronchodilator is bronchospasm is also present (COPD, Cystic Fibrosis, Asthma, etc.)
2. Generic name: Prednisone

Brand name: Metricorten, Sterapred, Sterapred DS

Comments: orally and can be taken at home. Oral prednisone is equally effective as nebulized dexamethasone when terating croup. In the hospital setting a patient is usually given IV solumedrol, which is titrated down, and then the patient goes home with prednisone pills. Prednisone packs allow the patient to slowly wean off the medicine.

3. Generic name: Dexamethasone

Brand name: Dexamethasone Intensol, Dexpac JR, Taperpak, Dexpak Taperpak

Comments: Can be aerosolized 5-10 cc and used to treat inflammation in the upper airways. Studies are inconclusive, yet some show it is more effective than recemic epi in reducing upper airway inflammation for croup and post extubation inflammation. In fact, this study from showed that croupy kids given dexamethasone orally demonstrated more rapid resolution of symptoms as compared to those given the aerosolized version or placebo. New studies such as this show that aerosolized dexamethasone is inferior to intravascular dexamethasone and therefore the medicine should always be given via the IV. The study also showed that nebulized steroids are more expensive. Should be used for croup only when the patient is in respiratory distress. Studies also show shorter hospital stays in patients croupy kids given this medicine. It also allows for less use of epinepherine. Studies like this show it is equally as effective as oral prednisone when treating croup.

Mucolytics: Used for patients with thick, tenacious or inspissated secretions that cannot be easily removed (usually COPD or CF patients).
Generic name: Acetylcysteine

Generic name: Mucomyst

Delivery device: 10% and 20% (4, 10 and 30cc vials) via SVN

Adult dose: 3-4 cc or 6-10 cc of the 10% dose TID or QID (dilute 20% for equivilancy) We usually just give 1 cc dose

Action: Decreases sputum viscosisity on contact

Comments: Can cause bronchospasm and should be given with a bronchodilator, usually Albuterol or Xopenex. The medicine disolves disulfide bonds and is used to liquify thick tenacious secretions and for acetaminophen overdose. Side effects include nausea and vomiting, bronchospasm, bronchorrhea, airway obstruction, incompatibility with antibiotics and are rare.

2. Generic name: Sodium bicarbonate

Brand name: none

Delivery device: 2% solution svn

Adult dose: 2-5cc prn

Action: Decreases sputum viscosity on contact

Comments: Can cause bronchospasm so should be given with a bronchodilator. Increases mucus pH thereby decreasing its viscosity.

3. Generic name: Dornase Alpha (recombinantDNAse)

Brand name: Pulmozyme

Delivery device: SVN: 2.5cc single-use ampules (1.0 mg/cc)

Adult dose: 1 ampule per day or BID

Action: Decreases sputum viscosity on contact

Comments: Can cause bronchospasm, so should be given with bronchodilator; specifically indicated for CF patients. Decreases the frequency of respiratory infection in cystic fibrosis patients requiring parenteral antibiotics, and for treating viscious secretions seen in patients with cystic fibrosis. Side effects include: Voice alteration, pharyngitis, larygitis, rash, chest pain, conjunctivitis.

Wetting Agents: Water: Given orally or IV fluids are the best mucolytic. It's also used to treat dehydration caused by increased work of breathing that results from asthma or COPD exacerbations. (Note that sterile distilled water aerosol is very irritating to the airway and may cause bronchospasm.

Saline solutions include:

1. 0.45% saline: hypotonic saline

Comments: Used to liquify secretions and humidify the airway; may be irritating and cause swelling of dried retained secretins or bronchospasm. Not used often anymore, but still available some places
2. 0.9% saline: Isotonic or normal saline

Comments: Sometimes used to liquify secretions and to humidify the airway, although studies question it's effecatiousness in this area and it's not used so much any more. It is commonly used as a diluent for medication, as you'll see it listed many times in this post for aerosolized medication. Most medicines that come in an amp are pre mixed with 2-3cc of normal saline.

3. 1.8-15% saline: hypertonic saline

Comments: Occasionally used to induce sputum specimins, and can irritate the airway and cause bronchospasm or secretion obstruction. Study results are inconclusive that it does any good and therefore it's rarely used.


1.Generic name: Colisimethate

Brand name: Colistin, Coly,Mycin

Delivery device: 150 mg vials (powder); add 2 cc sterile water

Adult dose: 37.5-150 mg every 8-12 hours

Action: Anti-pseudomonal agent

Comment: Requires valved nebulizer to prevent the RT or others from inhaling the medicine

2. Generic name: Tobramycin
Brand name: Tobi

Delivery device: 300 mg in 5 cc saline ampule

Adult dose: 300 mg every 12 hours for 28 days; followed by 28 days off

Action: Anti pseudomonal agent

Comments: Many side effects; do not mix with other drugs; give bronchodilator first; requires valved nebulizer

3. Generic name: Nanimivir
Brand name: Relenza
Delivery device: DPI 5 mg/ blister

Adult dose: 10 mg (2 blisters) BID for 5 days

Action: Stops viral replication (influenza A and B)

Comments: Not for use in asthma or COPD patients; if bronchospasm develops, stop therapy and treat immediately

Generic name: Pentamidine

Brand name: Nebupent, Pentam 300

Comments: According to, it's used to prevent and treat serious infections such as pneumocystis pneumonia. Generally, it's used on patients who have a diminished immune system, such as AIDS and certain cancers. It may effect blood sugar levels, cause headache, chills, anxiety, loss of appetite, increase urine output, and cause drowsiness. Must be given with a filtered nebulizer to prevent therapist from inhaling medicine.

Mineral supplements:

Generic name: Magnesium sulfate

Comments: According to, it is a smooth muscle relaxant by interfering with calcium uptake. It also has counteracting effects against bronchoconstrictors like histamine, methacholine, and metabisulfite. Intravenous magnesium sulfate is generally considered a mild bronchodilator and studies show that use of this for exacerbations of asthma may be of some benefit. It has been used more and more in hospitals, especially for difficult to manage asthma patients. As this study notes, magnesium sulfate does have significant bronchodilating effect, but results were not significantly different from an Albuterol nebulizer treatment. It is an option for use in hospitals for the treatment of asthma. May be nebulized at 95mg to 385 mg mixed with 2-3cc normal saline, up to four doses with 20 minutes between doses. Adverse effects are minimal. Studies show that nebulized magnesium and Albuterol together showed even greater bronchodilating effects lasting up to 20 minutes. Improvement in some patients was significant. Exact mechanism of action is yet unknown.

Loop Diuretics: Used to decrease preload to the heart by causing patinet to urinate. Used for right heart failure, left heart failure, valvular diseases and kidney failure.

1. Generic name: Furosimide
Generic name: Lasix

Comments: Commonly known as the water pill. According to emedtv, it's a loop diuretic because it effects the loop of henle, a part of the kidney. "It works by increasing the amount of saltand water that the kidneys remove from the blood. This extra salt and water is then passed out through the urine. By increasing the amount of water removed from the blood, furosemide causes a decrease in blood volume. Because of this effect, the drug can lower blood pressure and help with water retention." Aside from that, studies also show that aerosolized lasix (as I wrote about here) it has been proven to reduce dyspnea in COPD patients.

2. Generic name: Bumetanide
Brand name: Bumex

Comments: Used in patients when high doses of Furosemide are inefective. According to Wikipedia it is 40 times more potent than Furosemide.

Other diuretics:

1. Generic name: Chlorothiazide

Brand name:Diuril

Comments: Used as a diuretic to treat pulmonary or other edema throughout the body. Also used to treat edema caused by corticosteroid therapy, hepatic cirrhosis, and estrogen therapy. It's also used as an antihypertensive. should not be used during pregnancy. May use in pregnancy if pedal edema is due to cardiac abnormalities, but not for normal pedal edema caused by the mechanical process of pregnancy (source

2. Generic name: Hydrochlorothiazide

Brand name: Hydrodiuril

Comments: A water pill used to treat accumulation of fluid in the body (edema) and hypertension. It blocks salt and fluid reabsorption by kidneys and therefore increases urine output. Can be used for edema caused by heart failure, cirrhosis, chronic kidney failure, and systemic corticosteroids. (source
3. Generic name: Mannitol

Brand name: Osmitrol

Comments: Osmotic diuretic. Uses are cerebral edema, drug toxicity and overdose. Adverse effects include increased cardiac workload due to increased plasma volumes. According to Wikepedia it's an osmotic diuretic and weak vasodilator to lower blood pressure. It was originally isolated from flowering plants called manna, hence the name.

4. Generic name: Acetazolamide

Brand name: Diamox

Comments: Used for cerebral edema and peripheral edema; adverse effects include metabolic acidosis; drug is contraindicated in renal failure or respiratory failure because it causes excretion of bicarbonate ions. Opiates, in small doses, have also been proven to reduce the feeling of air hunger (dyspnea). The reason is generally unknown, although (according to, it's believed to be due to vasodilation, decreased vascular resistance (decreased blood pressure). Plus, "

Analgesics (opoids): Used to reduce patient's sensation of pain. Opiates (narcotics) are the most commonly used in the hospital setting for treatment of disease processes or post operative. According to "they also decrease brainstem responsiveness to carbon dioxide (the primary mechanism of opioid induced respiratory depression) and lessen the reflex vasoconstriction caused by increased blood PCO2 levels so that the perception of dyspnea is reduced." They also reduce dyspnea by vasodilation and decreased peripheral vascular resistance (blood pressure). May cause hypotension and increased hystamine release. It also may decrease gastrointestinal motility (another thing to watch out for). When nebulized, medical professionals must wear appropriate masks to prevent inhalation of opoids. Can be given as needed or continuous infusion. As needed is probably better because it allows you to prevent over sedation
1. Generic name: Morphine

Brand name: none

Comments: Morphine is an opoid and also a mild bronchodilator, and it has also been proven to help with anxiety and the feeling of dyspnea or air hunger in patients with severe or end stage COPD and with severe forms of asthma and end stage lung cancer. It can be provided orally, under the tongue (sublingually), injection and even inhalation via a nebulizer. Here's a scientific article about Morphine for dyspnea, and here's a post from asthmatic Breathin Stephen who uses Morphine for his dyspnea. Nebulized morphine may be an easy method to provide the patient with dyspnea relief and to provide psychological comfort. The therapeutic dose of nebulized morphine is 5 mg of the 0.1% solution every 4 hours as needed. Studies have shown (click here) that opiates (nebulized or other) decrease shortness of breath, allow for a greater feeling of relaxation, and increase exercise tolerance. No significant difference was reported with doses higher than 5 mg. However, since morphine can cause bronchoconstriction, promote histamine release, and depress respirations, it should be used with caution. It also can cause hypotension, so it's ideal for anxious patients in respiratory disterss with high blood pressure.

2. Brand name: Hydromorphone

Generic name: Dilaudid

Comments: A narcotic. 4mg every four hours can be mixed with normal saline and given via nebulizer in patients who are allergic or intollerent to Morphine sulfate to treat dyspnea. Some patients have benefited from 1 mg nebulized dilaudid every four hours, and some required as much as 20mg to receive benefits. Symptom relief was generally felt within 15 minutes and most patients suffered no adverse effects.

Nebulized Dilaudid:  Nebulized to treat severe dyspnea.  It sometimes works better for those suffering from dyspnea due to fewer side effects than the pill form of opiates.  One common side effect is headaches.

3. Generic name: Fenatanyl

Brand name: Dublimaze

Comments: A narcotic. Can also be nebulized and given for dyspnea relief. 25 micrograms in 2cc normal saline is the usual dose. 81% of patients in one study noted relief within 5 minutes, and relief lasted up to an hour. Oxygen saturations and respiratory rate also improved. So it can be used as an alternate for those patients allergic to or intollerent to morphine sulfate. Optimum dose and duration of benefits are unknown at this time. Unlike Morphine, it does not have the side effect of histamine release. It is expensive however.

4. Generic name: Codeine

Brand name: none

Comments: A narcotic. 15 mg nebulized codeine can be given to patients for dyspnea relief is they have an allergy or intollerence to morphine sulphate (source

5. Generic name: Hydrocodone

Brand name: none

Comments: A narcotic

6. Generic name: Ocycodone

Brand name: Oxycontin

Comments: A narcotic

7. Generic name: Meperedine

Brand name: Demerol

Comments: A narcotic. Not a very good analgesic. It's highly addictive, may cause hallucinations, and buildup can lead to ceizures.

8. Generic name: Anileridine

Brand name: Leritine

Comments: New analgesic no longer available in the United States. Is available in Europe. Similar to Demerol but chemicals are altered slightly to give it a stronger analgesic effect. It's available as a tablet or injection, yet 25mg can be aerosolized in a nebulizer for treating dyspnea.

Analgesics (non opoids)

1. Generic name: Ketorolac

Brand name: Toradol

Comments: Does not cause respiratory depression, however it causes incerased side effects in critically ill. It may cause renal failure and gastritis.

2. Generic name: Tramadol

Brand name: Ultram

Comments: Is a narcotic-like pain reliever. Can be taken while you are working. Use to treat moderate to severe pain when over-the-counter medicines to not help. Time released capsules are available for those who need pain relief around the clock. This medicine should only be used as prescribed, because it can become addictive. The addictive effect of this medicine can be enhanced if used with alcohol. Should not be taken with anti-depressants, muscle relaxers, or medicine for nausea or vomiting. Overdose can have same effect as opiates: slow and shallow respiratory rate, and possible cessation of breathing. Side effects can be severe, so precaution should be used.

2. Generic name: Asprin:

Brand name: none

Comments: Pain reliever and also a blood thinner. Used as a regular treatment for mycardial infarctions to thin the blood and often patients use this daily.

3 Generic name: Acetaminophen

Brand name: Tylenol

Comments: According to pubmed, Tylenol is a pain reliever and fever reducer. Recent studies have linked Tylenol with asthma.
4. Generic name: Ibuprophen

Brand name: Motrin,

Comments: Pain reliever and fever reducer. It's a nonsteroidal anti-inflammatory.

Neuromuscular blockers (paralytics): Indicated for patients receiving mechanical ventilation in order to reduce spontaneous breathing, and prevent movement that can dislodge airways, catheters and chest tubes. Can also be used to prevent increased intracraneal pressure. Can also be used to reduce oxygen consumption in patients with poor cardiopulmonary status, and to improve patient synchrony with the ventilator. They increase risk of DVT, pressuer ulcers, and nerve compression syndromes. Any paralytic may cause prolonged muscle weakness if used for greater than 48 hour. This effect is increased when corticosteroids are used with the paralytic. Therefore paralytics should not be used with any patient on corticosteroids. I've seen this, and it's not good.

Depolarizing agents
1. In. Generic name: Succinylcholine

Brand name: Anectine

Comments: This is a depolarizing neuromuscular blocking agent used to cause total muscle contraction (twitching, fasciculation) followed by complete muscle paralysis. It has a rapid onset (1-1.5 minutes), and it is short acting (7-12 minutes) so there is no need for a reversal. It is primarily used for endotracheal intubations. Side effect is increased potassium and incrased intracraneal pressure.

Non-depolarizing agents

2. Generic name: Pancuronium
Brand name: Pavulon

Comments: It's a nondepolarizing neuromuscular blocking agent. It binds to receptor sites to prevent stimulation of muscles, resulting in complete paralysis. It has a rapid onset of action (3-5 minutes), and has a long duration of action (35-120 minutes). It can be reversed if desired. Recommended when paralysis is indicated for longer periods of time. This medicine does not affect pain perception or level of consciousness, so patient should also receive sedation and analgesia (pain control). It's inexpensive and lasts long. Side effects: tachycardia

3. Generic name: Vecuronium

Brand name: Norcuron

Comments: See comments for Pavulon above.Onset 1.5 minutes and lasts 30 minutes. Less cerebral vascular effect as other paralytics. Side effect: bradycardia.

4. Generic name: Atracurium

Brand name: Tracrium

Comments: See comments for Pavulon above. Onset 2 minutes and last 30 minutes. May cause rash or histamine release.

5. Generic name: Cisatracurium

Brand name: Nimbex

Comments: See comments for Pavulon above.

6. Generic name: Rocuronium

Brand name: Zemeron

Comments: Onset 1 minutes and lasts 30-60 minutes. Used to relax muscles. According to, Usually given before general anesthesia to prepare you for surgery. It also relaxed your throat so it's easier to insert an ETT. No hemodynamic effects, but it is expensive.

7. Generic name: Tubocurare

Brand name:

Comments: Used during surgery as muscle relaxant and anesthetic. Onset 6 minutes and duration is 80 minutes.

Anti narcotics:

1. Generic name: Nalaxone hydrochloride

Brand name: Narcan

Comments: Reverses the effects of opiates such as Morphine. It's a white powder that's soluble in water, and is injected into the IV. Reverses respiratory depression caused by opoids. Can work really fast to wake patients up. According to RXlist, it reverses methadone, propoxyphene, nalbuphine, pentazocine, butorphanol, cyclazocine.

Leukotriene antagonists: Also referred to as leukotriene modifiers. They are non steroid drugs that have been approved for use in cases of mild to moderate persistent asthma. They are known to block leukotrienes that cause bronchospasm and inflammation of the lungs during an allergic/ asthma attack. Can also be used as a premedication for exercise induced asthma. They act to improve lung function, reduce symptoms and the need for beta agonist drugs. Sometimes these alone can prevent asthma. If these alone don't work, then inhaled corticosteroids can be tried, or combination medicines like Advair and Symbicort. They are generally used as a means of controlling asthma long term, should be taken once a day, and should be taken every day to control asthma because it takes 1-2 weeks to obtain a therapeutic level in your system. They are also used to treat rhinitis and hay fever, and may be used in conjunction with an antihistamine if needed. These should not be used to treat an acute exacerbation of asthma.

1. Generic name: Zafirlukast
Brand name: Accolate

Comments: This medicine is usually taken by mouth twice daily. For more information click here.

2. Generic name: Zileuton

Brand name: Zyflo

Comments: It's generally take 4 times daily. As you can see here, this medicine has been discontinued.

3. Brand name: Montelukast

Generic name: Singulair

Comments: The FDA has ordered a black box warning to be added to this medicine because some patients taking it have noted suicidal thoughts. However, the FDA also notes no studies have confirmed this. This medicine should be used when the advantages outweight the disadvantages. The medicine is generally safe. For more information click here.

Xanthines: These are inhibitor drugs that indirectly increase the amount of cAMP within smooth muscle. The inceased amount of cAMP then causes bronchodilation. Other xanthines include caffeine (coffee). Side effects include tachycardia, palpitations, jitters, irritability and diuresis.

1. Generic name: Theophylline

Brand name: Theo-dur, Theolair

Delivery device: oral by tablet, extended release, regular release, syrum and elixer

Adult dose: depends on patient, and should be titrated to maintain a therapeutic level; Remind patient to take doses at the same time every day to maintain therapeutic levels in their system.

Comments: Safe therapeutic blood level of theophylline is 10-20 mg/ml to optimize bronchodilation. blood levels are important to monitor in patients receiving methylxanthine drugs. Used to be a front line therapy for asthma, yet now is a secondary medicine to be used only for difficult to manage asthma cases. If the level exceeds 20, signs of toxicity may occur, including: tremors, nausea and vomiting, nervousness, seizures, tachycardia and other arrythmias that can lead to cardiac arrest. So it's important not to overdose and to have theophylline level checked at least once a year. I wrote about why theophylline is no longer a top line asthma therapy here.

2. Generic name: Aminophyline

Brand name: none

Delivery device: itravenous injection usually through IV

Adult dose: varies

Action: same as theophylline

Comments: Used in hospitals only. Same as theophylline except used in hospitals only and given by IV. For more information see theophylline.

Generic name: Oxytriphylline

Brand name: Choledyl

Delivery method: Regular release, extended release, syrum and elixer are available.

Comments: Similar to theophylline and should be taken at the same time every day to maintain therapeutic level.


1. Generic name: Omalizumab

Generic name: Xolair

Comments: The first IgE blocker developed to treat allergic asthma. Delivered by subcutaneous injection every 2-3 weeks. The dose is determined by the patient's IgE level and body weight. This is not a rescue medicine and should not be used to treat an asthma attack. The medication is for patients 12 years and older who have moderate to severe asthma that is triggered by eyar round allergens and who continue to have symptoms despite inhaled steroid therapy. This medicine is very expensive. Some studies I've seen show mixed results. All asthma patients I've seen who have used this medicine have said it didn't do any good. So, we'll have to wait for further study results to see if this medicine should be used in the future.

Anti- arrhythmic agents:

1. Generic name: Lidocaine

Brand name: Xylocaine

Comments: Can be injected directly under the skin prior to inserting IVs or doing blood gases to numb the area. Also a 5cc of 2%, Lidocaine solution or 100-200mg or 4cc of 4% solution can be aerosolized to numb the airway prior to bronchoscopies or for post extubation laryngospasm. Studies like this show it has been efficatious in reducing laryngospasm. Also can be used to treat laryngospasm caused by anaphlaxis. Also used to control PVCs, pulseless Ventricular Tachycardia, or ventricular fibrilation. Some reports, as this medscapes article notes, shows that aerosolized lidocaine can aleviate bronchoconstriction and cough. While this did work for many patients, it actually worsened bronchoconstricion short term in some patients and treatment had to be stopped before the patients were ultimately stabilized. Lidocain toxicity is a concern with higher doses, such as lightheadedness, hallucinations, tremors, and even cardiac arrest. So since studies are mixed, and side effects are a concern, care givers must "carefully" weight the potential risks with the benefits.

2. Generic name: Quinidine, Propranolol

Brand name: Inderal

Comments: Used to treat atrial arrythmias.

3. Generic name: Procainamide

Brand name: Pronestyl

Comments: see Atropine above

7. Generic name: Epinepherine:

Comments: see above

Anesthetics: These are used to relax airway smooth muscles. According to Fatal Asthma, "Rapid, dramatic improvement is reported, leading to more effective ventilation and in some cases early extubation." For other alternative therapies for asthma or COPD click here.

1. Generic name: Ketamine hydrochloride

Brand name: Ketamine

Comments: This is a smooth muscle relaxant and antihistamine, and is given intravenously. It's a really good bronchodilator. Of course this medicine is a known hallucinogenic, and it is a sedative. Many doctors prefer to wait until a patient is intubated to use it, and follow it up with a paralytic, as you can read here. May cause hypertension, hallucinations, hypertonicity, and nightmares.

2. Generic name: Isoflurane

Brand name: Forane

Comments: This is an anaesthetic and bronchodilator that has been proven to be efficacious in ventilated patients in status asthmaticus.

3. Generic name: Propofol

Brand name: Diprovan

Comments: Used as a sedative, amneseic and anesthetic. RTs will see it used on ventilator patients, particularly asthma and COPD patients. However, it must be used cautiously because it can cause respiratory and cerebral vascular deperssion. Rapid onset in 1 minute, and peaks at 2 minutes. Duration is 4-8 minutes. Not effected by kidney and liver disease.


1. Generic name: Haloperedol

Brand name: Haldol

Comments: It's an anti-psychotic tranquilizer used for patients that are non-compliant and confused, agitated, delerious, and/ or psychotic. Does not cause respiratory depression.

Sedatives: Anti anxiety medicine. Used to manage fear, anxiety and agitation, reduce pain, increase comfort while receiving mechanical ventilation, reduce oxygen demand, and to induce sleep. Some also create amnesia. Benzodiazepines are the most common and include the following. May be used to prevent sleep deprivation and delerium in ventilator patients, and to help with alcohol and drug withdrawl, depression, etc. RTs must be aware that sedatives may increase length of stay on ventilators and increase costs. Therefore, a good ventilator strategy is to have sedation vacations every day where you can assess patient for weaning criteria. As appropriate, sedation should be stopped no less than 2 hours prior to this assessment. Also, must be used carefully because a patient may develop a dependance.

Lopressor will be ordered to lower blood pressure when it gets too high, and Nitroprusside used to increase it when it gets low.

PDE inhibitors: Used to increase cardiac contractility to treat cardiac shock

9. Generic name: Amrinone (inamrinone) changed to Amiodarone

Brand name: Inocor, Cordarone, Pacerone, Cordarone

Adult dose: 50 mcg/kg/ bolus and 0.375 to 0.5 mcg/kg/min

Comments: Positive inotropic (increases cardiac contractility) and vasodilator with little effect on heart rate. Used to treat CHF short term only (in the hospital). Blood pressure, pulse, and EKG should be constantly monitored. Given by IV. Lasix should not be inserted into same IV line.

Beta blockers

11. Generic name: Labatolol

Brand name: Normodyne, Trandate

Adult dose: Bolus 20 mg; infusion is 2mg/ min

Comments: A vasodilator. Increases blood flow through the veins to increase blood pressure. Decreases systemic vascular resistance and blood pressure without tachycardia. Used in emergency situations when patient has a very low blood pressure. Useful when patient has had an aortic dissection.

Ace inhibitors: The angiotension converting enzyme (ACE) triggers a reaction that causes the blood vessels to narrow resulting in high blood pressure. ACE inhibitors slow or inhibit the activity of the ACE enzyme, this causes the blood vessels to dilate, and blood pressure is reduced. In essence these are used to terat shock when afterload reduction is needed. Afterload is the force the heart has to pump against. When afterload is high, blood pressure is high.

Generic names (brand names): benazepril (Lotensin), captopril (Capoten), enalapril (Vasotec), fosinopril (Monopril), lisinopril (Prinivil, Zestril), moexipril (Univasc), perindopril (Aceon), quinapril (Accupril), ramipril (Altace), trandolapril (Mavik).

Medicines no longer prescribed or being phased out:


1. Generic name: Bitolterol

Generic name: Tornalate

Delivery device and dose: Adult dose:
  • SVN: 1.25 mL TID/ QID
  • MDI: 2 puffs Q6 hours
Action: Onset in 3-4 minutes, peaks 5-20 minutes; Duration 1-3 hours (short lived)

Comments: Mild CV/CNS side effects; do not mix with other drugs

4. Generic name: Pirbuterol

Generic name: Maxair

Delivery device: MDI: (200 mcg/puff)

Adult dose: 2 puffs q 4-6 hours

Action: Onset in 5 minutes; peaks in 1/2- 1 hour; duration is 3-5 hours (medium)

Comments: Mild CV/CNS side effects. This medicine is currently being phased out

Mast Cell Stabilizers:

1. Generic name: Cromolyn sodium

Brand name: Intal, Aarane

Adult dose:

  • SVN: 20 mg four times a day
  • MDI dosage is 2 inhalations four times a day
Comments: Improvement in symptoms usually occurs in 4 weeks, and therefore it's a medicine that should be used every day. Becuase it's needed 4 times a day, compliance with it has been questioned, and this is one of the reasons it's been phased out. Inhaled corticosteroids have been proven more effective. Phased out because it's CFC inhalers are being phased out in favor of HFA inhalers, and the manufacturers decided it wasn't used enough to warrent the cost of investigating the costs and methods of creating an HFA inhaler or DPI.

2. Generic name: Nedocromil sodium

Brand name: Tilade

Delivery device: Only available as MDI

Dosage: 2 puffs 4 times a day

Comments: Due to 4 puffs 4 times a day compliance became an issue. Also CFC inhalers were phased out and it wasn't cost effective to make any changes or to continue the medicine.


1. Generic name: Isuprel

Brand name:

Comments: Increases heart rate and heart oxygen consumption. May worsen ischemia. No longer used.

2. Generic name: Ephedrine

Brand name: none

Adult dose: 5-25 mg IVP

Comments: Used to relieve congestion due to colds, hay fever, allergies, etc. It's a decongestant and bronchodilator. Releases tissue stores of epinepherine to cause bronchodilation. Longer lasting and less potent than epinepherine. No longer available over the counter but still available to anesthesiologists.

New nebulized medicines I haven't classified yet:

*Not necessarily classified as a beta adrenergic medicine, yet I'm listing it here for simplicity purposes because it has very strong bronchodilating effect.
