ABSTRACT: Pressurized metered dose inhalers (MDIs) are widely used dosage form for treatment of respiratory diseases, such as asthma and chronic obstructive pulmonary disease. The metered dose inhaler (MDI) contains the active pharmaceutical ingredient dispersed or solubilised in a high vapour pressure propellant and metered accurately in tens to hundreds of micrograms and administered directly to the lungs. The most dominant characteristics of MDI include their portability, convenience of use and quick effect. MDI comprises of drug formulation, propellant, metering valve, actuator, and container. This review contains overview of excipient selection, primary packaging material, propellant selection and formulation development of pMDI. Two of the most commonly used methods for the manufacturings of MDIs are cold filling method and pressure filling method. This review demonstrates different analytical techniques for characterization of pMDI’s like uniformity of delivered dose, water content, spray pattern and plume geometry were discussed. This review also presents in-vitro characterization, pharmacokinetic and pharamcodynamic study of MDI.
