Pharmacology is the study of how drugs affect living organisms and includes the research, discovery, and characterization of chemicals that show biological effects.
Pharmacology often focuses on understanding the mechanism of action of drugs, which describes how drugs exert their effects on the body.
Pharmacodynamics involves the study of the physiological effects of drugs on the body, and the mechanism of their actions, including the correlation of therapeutic effects and concentration of the drug.
Pharmacokinetics is a branch of pharmacology dedicated to the determination of the fate of substances administered to a living organism, focusing on absorption, distribution, metabolism, and excretion (ADME).
Side effects are undesired effects that occur in addition to the intended therapeutic effects of a drug.
The therapeutic window is the range of dosages of a drug that provides effective treatment without significant adverse effects.
Drug color does not affect pharmacokinetics; pharmacokinetics involves absorption, distribution, metabolism, and excretion.
Bioavailability is a measure of the extent and rate at which the active drug ingredient or active moiety is absorbed and becomes available at the site of drug action.
Monitoring clinical trials is crucial, as they help in determining the safety and efficacy of a drug before it reaches the general public.
Off-label use refers to the use of pharmaceutical drugs for an unapproved indication or in an unapproved age group, dosage, or route of administration.
