Metered-Dose Inhalers (MDIs): These devices deliver a specific amount of medication in an aerosol form. They often require coordination of inhalation and actuation. Dry Powder Inhalers (DPIs): These devices deliver medication in a dry powder form and are breath-activated, meaning the medication is released when the patient takes a deep, fast breath. Nebulizers: These devices convert liquid medication into a fine mist that can be inhaled over a period of time. They are particularly useful for individuals who have difficulty using MDIs or DPIs.
