Background: Poor inhalation technique is responsible for decreasing the efficacy of topical drug therapy in asthma and chronic obstructive pulmonary disease (COPD). Certain steps of the inhalation technique are erred most often and if ascertained, can be rectified leading to an overall improvement in the technique. The predictors for poor use can also be marked. Methods: Inhaler technique for pressurised metered dose inhalers (pMDI), pressurised metered dose inhaler with spacer and dry powder inhaler (DPI) was assessed in one hundred and five patients who fulfilled the inclusion and exclusion criteria and were enrolled in this study. Inhaler technique was assessed using an ERAS/ISAM Task force report based scores and the lung function using pulmonary function test (PFT).The technique was re-assessed and scored after a period of three months along with the assessment of the lung function by PFT. Results: The mean of ERS/ISAM task force report based score for evaluation of the techniques of inhalation increased from 5.79±2.58 to 8.23±2.41 (p
