Study Notes
General Pharmacological Principles
- Pharmacology is the science of drugs. It deals with the interaction of drugs with living systems.
- A 'drug' is any substance that can produce a biological response.
- Pharmacodynamics describes what the drug does to the body, including physiological and biochemical effects and mechanisms of action.
- Pharmacokinetics describes what the body does to the drug, including absorption, distribution, transformation and excretion.
Chapter 1 Introduction, Routes of Drug Administration
- Pharmacology encompasses all aspects of drug knowledge relevant to effective and safe medicinal use.
- Initially, drugs were mostly crude natural substances with limited efficacy.
- Modern pharmacology has elucidated drug mechanisms of action at various levels, like organ systems, subcellular, and macromolecular levels.
- Two main divisions of pharmacology are pharmacodynamics and pharmacokinetics.
- Drug nomenclature includes chemical names, nonproprietary names, and brand names.
- Pharmacopoeias and formularies are official compendia.
- Clinical pharmacology studies drugs in humans, including pharmacodynamics, pharmacokinetics, efficacy, and safety evaluations.
