What is a crucial action when using a DPI inhaler?

Inhalers that utilize dry powder inhalation (DPI) require a specific inhalation technique to ensure the medication is effectively delivered to the lungs. Inhaling quickly and forcefully creates the necessary airflow to disperse the dry powder, allowing it to be aerosolized and carried deep into the respiratory system. This fast inhalation helps the patient draw in the medication, ensuring that it reaches the intended site of action within the lungs.

This technique differs from other types of inhalers, such as metered-dose inhalers (MDIs), where a slower and more coordinated inhalation is typically recommended. When using a DPI, it is important for patients to be aware that if they do not inhale strongly enough, the powder may not be adequately aerosolized, leading to reduced efficacy of the medication.
