Interaction between a receptor and a drug is based upon the law of mass action, which states the rate of a chemical reaction is proportional to the masses of reacting substances. 1 MIDW 125 Introduction to Pharmacology, Pharmacodynamics and Pharmacokinetics January 6-13, 2015 Welcome and introduction Dr. Jennifer Shabbits ([email protected]) Office: LSC 1542 / 604-822-9729 • PhD (Pharm Sci, UBC) New Drug Development and Approval Process. They are all artistically enhanced with visually stunning color, shadow and lighting effects. Receptors have become the central focus of investigation of drug effects and their mechanisms of action (pharmacodynamics). Pharmacokinetics (PK) refers to the movement of drugs through the body, whereas pharmacodynamics (PD) refers to the body’s biological response to drugs.

The Organic Chemistry of Drug Design and Drug Action. Pharmacodynamics is the study of the biochemical and physiological effects of drugs on the body or on microorganisms or parasites within or on the body and the mechanisms of drug action and the relationship between drug concentration and effect The most common mechanism is by the interaction of the drug with tissue receptors located either in cell membranes or in the intracellular fluid.

The receptor concept, extended to endocrinology, immunology, and molecular biology, has proved essential for explaining many aspects of biologic regulation. Interaction of drugs with cellular proteins, Receptors largely determine the quantitative, Receptors are responsible for selectivity of drug, A protein macromolecule produced by the body that, Ability to recognize specific molecular shapes, only a limited group of neurochemicals or drugs, ? • In Greek Pharmacon = Drug Dynamics = Action/Power It covers all the aspects relating to “What a drug does to the body” Mechanism of action You just clipped Be16b033 Internship Report Molecular Modeling & Drug Design.
