What is a key feature of a Dry Powder Inhaler (DPI)?

A key feature of a Dry Powder Inhaler (DPI) is that it does not require activation timed with inhalation. Instead, patients can simply load the medication and inhale deeply. The design of a DPI relies on the patient's inhalation effort to draw the powdered medication from the device into the lungs. This allows for a more straightforward process since users do not need to coordinate pressing a canister or device with their breath, as is necessary with some other inhalation methods.

The benefits of this feature include the potential for improved medication delivery since the patient must inhale forcefully to effectively disperse the powder. This mechanism makes DPIs particularly suitable for individuals who can generate sufficient inhalation flow rates, enhancing the overall efficacy of the medication delivery.
