Dry-powder Inhaler

A Dry-powder Inhaler (DPI) ^[1] is a device that delivers medication to the lungs in the form of a dry powder. DPIs are commonly used to treat respiratory diseases such as asthma and chronic obstructive pulmonary disease (COPD).

Pronunciation

Dry-powder Inhaler: /draɪ 'paʊdər ɪn'heɪlər/

Etymology

The term "Dry-powder Inhaler" is derived from the English words "dry" and "powder", referring to the state of the medication, and "inhaler", which refers to the method of administration.

Usage

Dry-powder Inhalers are used to deliver medication directly to the lungs. This is beneficial for treating respiratory diseases as it allows for a higher concentration of the drug to be delivered directly to the affected area, while reducing systemic side effects.

Types of Dry-powder Inhalers

There are several types of DPIs, including single-dose DPIs, multiple-dose DPIs, and reservoir DPIs. Each type has its own advantages and disadvantages, and the choice of DPI often depends on the specific needs of the patient.
