Study Notes

Definition of Terms

Toxicology is the study of the adverse effects of chemicals on living organisms.
Pharmacology is the study of the effects of drugs on the body, including the mechanism of action and physiological effects.
Pharmacy as a science focuses on the discovery, development, and use of drugs for the prevention and treatment of diseases.
Receptors in pharmacology are molecules that bind to specific drugs, allowing them to exert their effects on the body.

Sources of Drugs

Minerals are a source of drugs, such as lithium used to treat bipolar disorder.
Plants are a source of drugs, such as morphine derived from the opium poppy.

Receptors

Type 1 receptors are located on the surface of cells and are responsible for quick responses to drugs.
Type 2 receptors are located inside cells and are responsible for slower responses to drugs.

Pharmacokinetics

Pharmacokinetics deals with the absorption, distribution, metabolism, and excretion of drugs in the body.
Absorption refers to the process of a drug entering the bloodstream after administration.

Pharmacodynamics

Pharmacodynamics deals with the effects of drugs on the body, including the mechanism of action and physiological effects.
The main focus of pharmacodynamics is the study of the response of the body to drugs.
Semi-synthetic drugs, such as oxycodone, are an example of drugs that act on specific receptors.

Drug Action Mechanisms

Inhibiting cell wall synthesis in bacteria is an example of a drug action mechanism that involves changing metabolic processes.
Ion channel blockers are a type of drug that acts through interference with the selective passage of ions across the cell membrane.
