Inhaler

Inhaler

Inhaler is a medical device used for delivering medication into the body via the lungs. It is primarily used in the treatment of asthma, chronic obstructive pulmonary disease (COPD) and other respiratory diseases. The medication is most commonly inhaled to minimize side effects compared to systemic medications due to its direct application to the respiratory tract.

Types of Inhalers

Inhaler

There are two main types of inhalers: metered dose inhalers (MDI) and dry powder inhalers (DPI).

Metered Dose Inhalers

Metered dose inhalers (MDI) are the most common type of inhaler. They consist of a pressurized canister containing medication that fits into a boot-shaped mouthpiece. The medication is released by pressing the canister into the boot.

Dry Powder Inhalers

Dry powder inhalers (DPI) are a type of inhaler that deliver medication in the form of a dry powder directly into the lungs. They do not contain propellants and the medication is released by the patient's inhalation.

Usage

Inhalers are used by inserting the mouthpiece into the mouth and then pressing down on the canister to release the medication while inhaling. It is important to coordinate the pressing and inhaling to ensure the medication is delivered to the lungs.

Side Effects

Possible side effects of using an inhaler include oral thrush, hoarseness, and throat irritation. These can be minimized by rinsing the mouth after using the inhaler.
