Pharmacodynamics- Principles and Mechanism of Drug Action
Pharmacodynamics- Principles and Mechanism of Drug Action Pharmacodynamics, a core area of pharmacology, delves into the intricate interactions between drugs and the biological systems they affect. Unlike pharmacokinetics, which focuses on the absorption, distribution, metabolism, and excretion of drugs, pharmacodynamics explores the effects of drugs on the body and how these effects are achieved. This…

Distribution of Drugs
Distribution of drugs Distribution in pharmacokinetics refers to the reversible movement of a medication from one part of the body to another. A medication needs to be dispersed into intracellular and interstitial fluids after it is directly administered or absorbed and goes into systemic circulation. Once a medication enters the bloodstream, it is dispersed to…
