In Asthma MDI; it shows clinical significance but statistically non-significant (p=0.10) and Rota-haler; shows both clinical and statistical significance (p=0.01). In COPD MDI (p=0.02) and Rota-haler (0.04); shows both clinical and statistical significance (p=0.02). It shows improvement in patients’ performance after providing information on use of inhaler. The most commonly prescribed drugs with MDI and Rota-haler were Short acting β-agonist, Corticosteroids and Combination of Bronchodilator and Corticosteroids.
