DPI (Dry Powder Inhaler)

A Dry Powder Inhaler (DPI) is a device used to deliver medication directly to the lungs in the form of fine dry powder. It works by patient inhalation—when you breathe in quickly and deeply through the device, it releases and carries the medication into your lungs, helping manage respiratory conditions like asthma or COPD. DPIs are portable, breath-activated, and do not require propellants or liquids, making them easy and convenient to use. Proper technique is essential for effective delivery, ensuring the medication reaches the airways to provide relief or control symptoms.
