Dry Powder Inhalation Excipients

Inhalers are becoming more and more popular as an efficient method of drug delivery. The success of these devices largely depends on the excipients used to carry the active ingredients. Dry powder inhalers (DPI) rely on advanced and well-designed excipients to deliver the correct active ingredients in the correct quantity to the correct location. These new methods provide benefits to patients by providing a wider range of therapeutic DPI products and provide new opportunities for the continued development of dry powder inhalers. In dry powder inhalation (DPI), the fastest growing and most important form of inhalation therapy, the effectiveness of the drug absolutely depends on the excipients used to carry it. Larger excipient particles release much smaller active ingredient particles into the patient's lungs, while they themselves deposit harmlessly on the throat.
