It is known that the success to any therapy for a disease depends on the compliance to medication by the patients.

Compliance to prescribed therapy is an important determinant of success or failure of any treatment [1] . It has been found that only 50% sufferers of any chronic disease take their medications in therapeutically effective doses [2] . Incidentally, there is little data in our country about the compliance to asthma therapy.

We performed an OPD based survey on 96 patients on follow up at our clinic, a tertiary pulmonary OPD services in Kolkata. The mean age of the patients were 28-35 years with male female ratio being 2:1; urban patients predominated over rural patients in 7:1 ratio. Inhaled corticosteroid alone or with long acting bronchodilator (LABA) was prescribed universally with SOS medications for all. The adherence was assessed over a follow up period of 120 (+ 28.6) days: 16% patients stopped inhalers, the reason being feeling cured (88%) and financial constrains (11%). All these patients experienced worsening or relapse of symptoms on stopping inhalers.

This study was a questionnaire based one depending totally upon the response of the patients. Though such studies are easy and quick to perform and low in budget, they usually overestimate the compliance [1] . Gross overestimation regarding compliance in self reporting has been found in COPD patients for use of inhalers when compared to more objective methods [3] . Hence, we tried to reduce this limitation via a third party interview with the patients. It is possible that the routine programmed input to our patients with education, demonstration of inhaler use and reversibility / relief and regular follow up have helped us to attain such a good adherence of about 84%. The reason of non compliance is an obvious feeling of being cured in most of the noncompliant patient (88%) and financial constrains in a minority (11%). Other causes are not apparent from this small numbers of subjects interviewed. It is also possible that this high degree of compliance is likely to fall with time which is also observed in other diseases [4] .

This small study signifies that a similar but much well planned and elaborate study is essential to access the adherence to the therapy and factors for non compliance in our asthmatic populations. This probably will go a long way for the better care of the asthmatics in our country.
