COMPREHENSIVE
PHARMACOLOGY MODULE
A study guide covering essential pharmacology concepts, drug actions, therapeutic
classes, medication safety, and clinical applications
Educational use
This module is designed for learning and review. It is not a prescribing guide and does not replace official product
labeling, local formularies, clinical guidelines, or instructions from qualified health professionals.
Scope
The module moves from foundational principles to body-system pharmacology and medication safety. Drug
examples are included to illustrate classes and mechanisms; specific doses, contraindications, and treatment
decisions should be checked against current authoritative references.
Prepared as a general pharmacology study resource - 2026 edition

What is pharmacology?
Pharmacology is the study of drugs and their interactions with living systems. It includes how medicines act, how
the body handles medicines, desired therapeutic effects, unwanted effects, and the safe use of drugs.
Major branches
Area Focus
Pharmacokinetics What the body does to the drug: absorption, distribution, metabolism, and excretion.
Pharmacodynamics What the drug does to the body: molecular targets, physiologic effects, response, and toxicity.
Pharmacotherapeutics Use of drugs to prevent, diagnose, or treat disease.
Clinical pharmacology Study of drugs in humans, including therapeutic use and safety.
Toxicology Study of harmful effects of chemicals, including drugs at excessive or inappropriate exposure.
Pharmacogenomics Study of how genetic variation can influence drug response.
Drug names
• Chemical name: describes the chemical structure.
• Generic name: standardized nonproprietary name used across settings.
• Brand/trade name: proprietary name assigned by a manufacturer.
Core terms
• Indication: the condition or purpose for which a drug is used.
• Contraindication: a situation in which a drug should not be used because the risk may outweigh the benefit.
• Precaution: a condition requiring special care, monitoring, or adjustment.
• Therapeutic effect: the intended beneficial response.
• Adverse effect: an unwanted or harmful effect associated with medication use.
• Half-life: the time required for the amount or concentration of a drug in the body/plasma to decrease by about half
under the defined conditions.
Quick Check
1. How do pharmacokinetics and pharmacodynamics differ?
2. What is the difference between a generic drug name and a brand name?
3. Give one example of an indication and one example of a contraindication.
