Inhaler

An inhaler (or puffer) is a medical device used for delivering medication into the body via the lungs. It is mainly used in the treatment of asthma and Chronic Obstructive Pulmonary Disease (COPD). Zanamivir (Relenza), used to treat influenza, must be administered via inhaler.

To reduce deposition in the mouth and throat, and to reduce the need for precise synchronization of the start of inhalation with actuation of the device, MDIs are sometimes used with a complementary spacer or holding chamber device.

Decongestant inhalers are popular over-the-counter remedies for nasal congestion in the upper respiratory tract.

Types

Metered-dose (MDI)

The most common type of inhaler is the pressurized metered-dose inhaler (MDI). In MDIs, medication is typically stored in solution in a pressurized canister that contains a propellant, although it may also be a suspension. The MDI canister is attached to a plastic, hand-operated actuator. On activation, the metered-dose inhaler releases a fixed dose of medication in aerosol form. The correct procedure for using an MDI is to first fully exhale, place the mouth-piece of the device into the mouth, and having just started to inhale at a moderate rate, depress the canister to release the medicine. The aerosolized medication is drawn into the lungs by continuing to inhale deeply before holding the breath for 10 seconds to allow the aerosol to settle onto the walls of the bronchittus and other airways of the lung. Some inhalers are made to act instantly in case of an asthma attack, and others are made to act later.
