Study Notes
Pharmacology Branches
- Pharmacokinetics involves Absorption, Distribution, Metabolism, and Elimination
- Pharmacodynamics involves Protein targets for drug binding, Receptor types, Signal transduction, and Drug antagonism
Drug Sources
- Natural sources:
- Animal (e.g. beef insulin)
- Microbes (e.g. penicillins)
- Earth and soil (e.g. minerals: iron, calcium, sulfur, and potassium)
- Chemical Synthesis (man-made) (e.g. pethidine and sulphonamides)
Therapeutics and Toxicology
- Therapeutics: using drugs to prevent, diagnose, or cure disease
- Toxicology: studying undesirable effects of chemicals on living systems, from individual cells to complex ecosystems
Routes of Drug Administration
Parenteral Administration
- Intravenous (I.V)
- Intra-arterial
- Intracardiac
- Subcutaneous (S.C, e.g. insulin)
- Challenges:
- Difficulty finding a suitable vein
- Risk of rapid response and toxicity
- Requires trained personnel
