How do Dry Powder Inhalers work?

The basic structure of DPI

The Dry Powder Inhaler is mainly composed of three parts: the drug canister, the inhalation device, and the casing. Medicine canisters are usually made of metal or plastic and contain powdered medicine. The inhalation device is usually a removable plastic mouthpiece that is used to draw drug powder into the lungs. The casing is mainly used to protect the drug canister and inhalation device.

How DPIs work

When the patient inhales forcefully, the powder in the canister is carried into the lungs by the inhalation device. The key to Dry Powder Inhalers is the size and uniformity of the drug powder. If the powder is too large or uneven, it may stay in the throat or mouth instead of reaching the lungs. Therefore, manufacturers need to ensure that drug powders are uniform in particle size and shape.
