Dry Powder Inhalers (DPIs) are a type of inhalation device used to deliver medication directly to the lungs in the form of a dry powder. They are commonly prescribed for patients with respiratory conditions such as asthma and chronic obstructive pulmonary disease (COPD). DPIs do not use propellants, unlike metered-dose inhalers (MDIs), making them environmentally friendly and easier to use for some patients.
