A new study published in the Journal of Allergy and Clinical Immunology and reported on here might prove that it does matter what inhaled corticosteroid a doctor prescribes to control your asthma.
The study, performed by General Practise Research Database (GPRD) studied 2,000 individuals with asthma, and compared the performance of QVAR and Flovent in the United Kingdom for one year.
The study "revealed that those treated with QVAR™ either as initial therapy or with an increase or step-up in dose had a similar or better chance of achieving asthma control than patients who were treated with fluticasone. Asthma control was achieved in the QVAR™ population at lower doses of drug versus those in the fluticasone population. The full article is available at www.jacionline.org/inpress."
GPRD is a not for profit organization, and I have found no evidence that the makers of QVAR (Graceway Pharmaceuticals) had anything to do with the funding of this study. If you know otherwise leave a note in the comments below.
This might be significant research, since recently (as I wrote about here) we in the asthma community have discussed the "theory" that QVAR might have a particle size that reaches deeper into the lungs, way down to the smaller air passages. This may be the reason for the better asthma control.
So if you're having trouble gaining control of your asthma on Flovent, or Advair, or even Pulmicort, you might want to discuss with your physician the possibility of trialing QVAR either instead of your current medicine, or in conjunction with it.
