Pharmacology: Meaning and Definition

Pharmacology is the branch of science that studies how drugs interact with biological systems. It involves understanding the effects of chemical substances on living organisms, including their mechanisms of action, therapeutic uses, side effects, and toxicity.

Definition of Pharmacology:

Pharmacology is the study of the interactions between drugs and biological systems, including their absorption, distribution, metabolism, and excretion (ADME), as well as their effects on the body (pharmacodynamics) and how the body processes them (pharmacokinetics).

Branches of Pharmacology:

1. Pharmacokinetics – How the body absorbs, distributes, metabolizes, and eliminates drugs.
2. Pharmacodynamics – How drugs affect the body at the molecular and physiological levels.
3. Clinical Pharmacology – The study of drug effects in humans for safe and effective medical use.
4. Toxicology – The study of harmful effects of drugs and poisons on living organisms.
5. Neuropharmacology – The effect of drugs on the nervous system.
6. Psychopharmacology – The study of drugs that affect mood, behavior, and mental health.

Importance of Pharmacology:

• Helps in drug discovery and development.
• Ensures safe and effective use of medicines.
• Assists healthcare professionals in prescribing medications.
• Helps understand drug interactions and side effects.
