Dry powder inhalers (DPI) are used to deliver drugs in dry powdered form to the lungs of patients suffering from respiratory disorders. Dry powder inhalers are more preferred over pressurized metered dose inhalers (P-MDI) due to rising environmental concerns regarding chloro-flouro carbon (CFC) used as a propellant in P-MDIs. This has induced manufacturers to enter the dry powder inhalers segment, offering a wide range of products to patients suffering from respiratory disorders. [Source: The Edition Truth]
