Study Notes
Science of Pharmacology
- Pharmacology is a new field of science linking drug knowledge with various biological and chemical disciplines.
- Interconnected with fields like chemistry and biology, showcasing its multidisciplinary nature.
Branches of Pharmacology
- Major branches include:
- Clinical Pharmacology
- Pharmacoepidemiology
- Pharmacometrics
- Pharmacogenomics
- Pharmacogenetics
- Radiopharmacy
- Only a few branches are considered for focused study.
Distinction between Medicine and Drug
- Medicine: Substance administered to humans or animals for medicinal purposes, or as an ingredient in compounds intended for administration.
- Drug: Typically refers to illegal, recreational substances, or active ingredients in medicines; may also encompass substances of abuse.
Importance of Medicinal Purposes
- Medicines are crucial for:
- Treating and preventing diseases.
- Diagnosing diseases and evaluating physiological conditions.
- Providing contraception and anesthesia.
- Interfering with normal physiological functions, either temporarily or permanently.
Routes of Administration
- Enteral Route: Administered orally, includes sublingual methods.
- Parenteral Route: Delivered through injections (IV, IM, SC) and other methods.
- Other routes include:
- Inhalation
- Intranasal
- Intrathecal/Intraventricular
- Topical
- Transdermal
- Rectal and vaginal administration.
Pharmacokinetics
- Defined as a mathematical framework assessing drug behavior over time and how the body affects drugs.
- Key processes in pharmacokinetics include:
- Liberation (drug release)
- Absorption (into the bloodstream)
- Distribution (to tissues)
- Metabolism (chemical alterations)
- Excretion (removal from the body)
- Toxicity (adverse effects)
- Acronym for these processes: LADMET.
- Overall processes determine the concentration of drugs in the body.
