Overview of Pharmacology
Pharmacology is the science of drugs and their effects on living organisms. It encompasses various aspects, including:
- Pharmacodynamics: The study of the biochemical and physiological effects of drugs and their mechanisms of action.
- Pharmacokinetics: The examination of how the body absorbs, distributes, metabolizes, and excretes drugs.
- Toxicology: The study of the adverse effects of drugs and other chemicals.
Katzung's approach emphasizes the importance of understanding both the basic and clinical aspects of pharmacology, which is crucial for effective medical practice.
