Introduction
A metered-dose inhaler (MDI) is a device that delivers a specific amount of medication to the lungs, in the form of a short burst of aerosolized medicine that is usually self-administered by the patient via inhalation. It is the most commonly used delivery system for treating asthma, chronic obstructive pulmonary disease (COPD) and other respiratory diseases. Metered-dose inhaler products contain therapeutically active ingredients dissolved or suspended in a propellant, a mixture of propellants, or a mixture of solvents, propellants, and/or other excipients in compact pressurized aerosol dispensers. MDI is composed of mainly essential components:

And in europe it is filling through decentralize procedure. Meter dose inhaler is regulated by European medicinal agency(EMA) and it is monitored by Committee for proprietary medicinal products(CPMP) The regulatory requirements for abbreviated new drug application (ANDA) for Meter dose inhaler submitted into the CTD and modules requires for that is given below:
