Study Notes

Pharmacy

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

Etiology

The science of causes or origin of disease
All diseases must have causes, which produce an effect
Understanding etiology is crucial for effective treatment
Three main categories of etiology:
- Intrinsic: originating from within the body
- Extrinsic: originating from external factors
- Idiopathic: cause unknown

Pathophysiology

Combines "patho" (disease) and "physiology" (normal body function)
Studies functional, mechanical, and physical changes in the body due to disease or injury
Explains how these changes lead to signs and symptoms of various conditions

Pharmacotherapeutics

Combines "pharmaco" (drugs) and "therapeutics" (treatment)
Refers to the use of drugs to prevent, treat, diagnose, and manage diseases and medical conditions in humans

Pharmacokinetics

Combines "pharmaco" (drugs) and "kinetics" (motion or movement)
Examines the movement and transformation of a drug within the body over time
Summarized by the ADME pathway:
- Absorption: how the drug enters the bloodstream
- Distribution: how the drug spreads throughout the body
- Metabolism: how the drug is broken down
- Elimination: how the drug is removed from the body
Explains how the body interacts with administered substances (effect of the body on the drug)

Pharmacodynamics

Combines "pharmaco" (drugs) and "dynamics" (process)
Examines how drugs exert their effects on the body
- Includes interactions between drugs and their molecular targets
- Induces changes, producing physiological and biochemical responses
- Mechanism of action (MOA)
Explains the study of a drug's molecular, biochemical, and physiologic effects or actions (effect of drug on body)

Pharmacokinetics & Pharmacodynamics (Summary)

Pharmacokinetics: Effect of the body on the drug
Pharmacodynamics: Effect of the drug on the body

Bioavailability (F)

Combines "bio" (living organism) and "availability" (accessibility)
Refers to the proportion of a drug or substance that enters the bloodstream (systemic circulation) following administration
A measure of the extent and rate at which the active ingredient is absorbed
