Pharmacology constitutes a division of medical and pharmaceutical sciences that revolves around investigating the actions of drugs or medications. Its core segments encompass pharmacokinetics and pharmacodynamics. While pharmacokinetics delves into how biological systems influence a drug, pharmacodynamics explores how a drug impacts biological systems. In essence, pharmacokinetics explores the processes of absorption, distribution, metabolism, and excretion (ADME) of substances within biological systems, whereas pharmacodynamics examines the interaction of substances with biological receptors.
