Study Notes
Pharmacology
- Pharmacology is the study of substances that interact with living systems, often binding to regulatory molecules and influencing normal body processes.
- Drug-body interactions are categorized into pharmacodynamics (drug's effects on the body) and pharmacokinetics (body's effects on the drug).
- Pharmacodynamic properties determine the drug class and its suitability for a particular symptom or disease.
- Pharmacokinetic processes, including absorption, distribution, metabolism, and elimination, are crucial for drug choice and administration, especially for patients with specific health conditions.
Pharmacokinetics
- Absorption: Drug absorption from the administration site into the bloodstream (plasma).
- Distribution: The drug can then move from the bloodstream into interstitial and intracellular fluids.
- Metabolism: Drugs may be modified (metabolized) by the liver or other organs.
- Elimination: Drugs and their metabolites are removed from the body via urine, bile, or feces.
Drug Administration
- Drug administration methods are determined by therapeutic objectives (e.g., rapid onset, long-term treatment).
- Common routes of drug administration include enteral, parenteral, and topical.
