Exploring Pharmacology

Pharmacology is the study of how drugs interact with the body. It covers drug classifications, mechanisms of action, and therapeutic uses.

Drug Classifications

  • Analgesics: Relieve pain (e.g., acetaminophen).
  • Antibiotics: Fight bacterial infections (e.g., amoxicillin).
  • Antihypertensives: Lower blood pressure (e.g., lisinopril).

How Drugs Work

Drugs may bind to receptors, block enzymes, or alter chemical processes in the body. Understanding these mechanisms helps in preventing adverse reactions.

Application in Pharmacy

Pharmacy technicians must recognize common medications, their uses, and potential side effects. This knowledge supports safe dispensing and patient education.


Tip: Memorizing drug suffixes (like "-pril" for ACE inhibitors) helps in quickly identifying drug classes.

Examples

  • Identifying ibuprofen as a nonsteroidal anti-inflammatory drug (NSAID).

  • Recognizing that penicillin can cause allergic reactions in some patients.
