Study Notes
Pulmonary Drug Delivery
- Pulmonary drug delivery aims to treat respiratory diseases and disorders.
- The respiratory tract is the site for pulmonary drug delivery.
Anatomy of the Respiratory Tract
- The respiratory tract consists of the nasal cavity, pharynx, larynx, trachea, bronchi, and lungs.
- The thoracic cavity contains the lungs, heart, and major blood vessels.
Physiology and Airflow Dynamics
- Airflow dynamics involve the movement of air in and out of the lungs.
- Airflow dynamics affect pulmonary drug delivery.
Biological Barriers in Pulmonary Drug Delivery
- Biological barriers, such as mucociliary clearance and alveolar macrophages, can hinder pulmonary drug delivery.
- These barriers must be overcome for effective drug delivery.
Administering Drugs to the Lungs
- Liquid instillation is a method of administering drugs to the lungs.
Aerosol Properties
- Aerosol properties, such as particle size, affect pulmonary drug delivery.
- Aerodynamic diameter (dA) is a measure of aerosol particle size.
Aerosol Deposition Processes
- Inertial impaction, sedimentation, diffusion, and other mechanisms contribute to aerosol deposition in the lungs.
- Understanding aerosol deposition processes is crucial for effective pulmonary drug delivery.
Factors Impacting Pulmonary Drug Delivery
- Breathing patterns, aerosol characteristics, and other factors affect pulmonary drug delivery.
- A summary of these factors helps optimize pulmonary drug delivery.
Inhaled Drug Delivery
- Medicine development strategies involve consideration of aerosol characteristics and breathing patterns.
- Effective inhaled drug delivery requires understanding of pulmonary drug delivery principles.
