Pharmalogy Fundamentals

Definition and Scope

• Pharmalogy is a branch of pharmacology that deals with the study of pharmaceuticals and their effects on living organisms.
• It encompasses the study of drug discovery, development, and use, including their chemical composition, pharmacokinetics, pharmacodynamics, and therapeutic applications.

Subdisciplines of Pharmalogy

• Pharmacokinetics: the study of the absorption, distribution, metabolism, and excretion of drugs in the body.
• Pharmacodynamics: the study of the mechanisms of action of drugs on the body, including their effects on physiological systems and molecular targets.
• Pharmacotherapeutics: the study of the therapeutic uses and applications of drugs in the treatment of diseases and disorders.
• Toxicology: the study of the adverse effects of drugs and other chemicals on living organisms.

Key Concepts in Pharmalogy

• Pharmacological response: the effect of a drug on the body, which can be therapeutic or adverse.
• Dose-response relationship: the relationship between the dose of a drug and its pharmacological response.
• Potency: the ability of a drug to produce a pharmacological response at a given dose.
• Efficacy: the maximum response that can be produced by a drug.

Applications of Pharmalogy

• Drug discovery and development: the process of identifying, synthesizing, and testing new drugs for therapeutic potential.
• Clinical pharmacology: the study of the use of drugs in clinical practice, including their safety, efficacy, and optimal dosing.
• Pharmacovigilance: the monitoring and surveillance of drug safety and adverse effects in patients.
