Rotahaler

Inhalation is the preferred route of delivery for drugs intended for both COPD and asthma as drugs are delivered directly to their site of action,leading to a rapid onset of action and a low incidence of side effects.Incorrect technique when taking inhaled medications frequently prevents patients from receiving the maximal beneft from their medications[1].

Thus,prospective interventional study was conducted to evaluate the effectiveness of inhalation techniques of Rotahaler in patients with COPD and Asthma[2,3].Fifty follow-up cases were taken.The study was conducted in three phases viz.Phase 0(baseline),Phase 1(immediate),Phase 2(follow-up after 1 month).Verbal consent was obtained from patients before enrolling in the study and socio-demographic information of patients was collected by face to face interview.Baseline score of inhalation technique was taken before intervention.Patients were counseled about inhalational techniques of Rotahaler by verbal/physical demonstration.Immediate scoring was done after intervention and follow-up score was taken after one month.The percentage of patients performing the rotahaler technique increases from 61.5%at baseline to 85.50%in immediate and 84.75%in follow up.

A signifcant difference was observed in mean score of inhalation technique before and after intervention.Based on critical points,only 4%of the patients performed all steps correctly before intervention which increased in immediate to 32% and in follow up to 26%.Hence,intervention on inhaler technique improved the patient knowledge which may contribute to achieve better therapeutic outcome.
