Drugs affecting the respiratory system.
Differences in the disposition of drugs among exotic animals is a well-recognized hurdle when treating disease. Differences exist in pharmacokinetics, pharmacodynamics, and disease processes. This article focuses on the principles of treating respiratory tract diseases, with the recognition that not all drugs are indicated for use in all exotic species. The discussion begins with a description of respiratory physiology as it pertains to response to drugs, using the mammalian lung as a template. The role of respiratory defense mechanisms in airway protection and disease is addressed. Drugs used to treat the respiratory tract include the bronchodilators and anti-inflammatory drugs, drugs that modify respiratory secretions (e.g., mucolytics, mucokinetics, and expectorants), antitussive drugs, and decongestants. Aerosolization is an important adjuvant for respiratory therapy as long as precautions are met. Infectious diseases are among the more common respiratory diseases encountered, and the discussion includes a focus on the use of antibiotics for treating respiratory tract infections.
