Pulmonary Drug Delivery: Technology of Respiratory Inhalers
Respiratory inhalers are medical devices used to deliver medication directly into the lungs. This targeted delivery allows for high local concentrations of the drug with minimal systemic side effects.
Delivery Systems
Metered-Dose Inhalers (MDI): Use a pressurized propellant to release a specific dose of medication.
Dry Powder Inhalers (DPI): Breath-activated devices that require the patient to inhale deeply to draw the powder into the lungs.
Soft Mist Inhalers: Utilize mechanical energy to create a slow-moving aerosol cloud that is easier to coordinate with inhalation.
