    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
