Study Notes

Pharmacy

Pharmacy is a healthcare profession that combines health sciences and chemical sciences.
Pharmacy practice involves compounding, dispensing, reviewing medications, and providing drug information and clinical services related to patient care.
Pharmacists are drug therapy experts and primary health care professionals who optimize medication use.

Etiology

Etiology is the study of the causes or origin of disease.
Diseases have causes, which produce an effect.
Understanding the cause of a disease is important for proper treatment.
The etiology of disease falls into three main categories: intrinsic (coming from within), extrinsic (originating from external factors), and idiopathic (cause unknown).

Pathophysiology

Pathophysiology combines the words “patho” (disease) and “physiology” (normal body functioning).
It studies functional, mechanical, and physical changes in the body as a result of disease or injury.
It explains how these changes lead to the signs and symptoms of various conditions.

Pharmacotherapeutics

Pharmacotherapeutics combines the words “pharmaco” (drugs) and “therapeutics” (treatment of diseases).
It refers to the use of drugs to prevent, treat, diagnose, and manage diseases and medical conditions in humans.

Pharmacokinetics

Pharmacokinetics combines the words “pharmaco” (drugs) and “kinetics” (movement).
It examines the movement and transformation of a drug within the body over time.
It is summarized by the pathway ADME: Absorption, Distribution, Metabolism, and Elimination.
It explains how the body interacts with administered substances, in other words, the effect of the body on the drug.

Pharmacodynamics

Pharmacodynamics combines the words “pharmaco” (drugs) and “dynamics” (process).
It explains how drugs exert their effects on the body, including interactions between drugs and their molecular targets.
It studies a drug's molecular, biochemical, and physiologic effects or actions (Mechanism of Action—MOA).
In other words, it explains the effect of the drug on the body.

Pharmacokinetics & Pharmacodynamics: Summary

Pharmacokinetics: effect of the body on the drug (ADME).
Pharmacodynamics: effect of the drug on the body (MOA).

Bioavailability (F)

Bioavailability combines the words “bio” (living organism) and “availability” (accessibility).
It refers to the proportion of a drug or substance that enters the bloodstream (systemic circulation) when introduced into the body.
It measures the extent and rate at which the active ingredient is absorbed.
