Ppt Mechanisms Of Drug Action Powerpoint Presentation Free Download 8. some common terms • agonist: an agent which activates a receptor to produce an effect similar to a that of the physiological signal molecule, e.g. muscarine and nicotine • antagonist: an agent which prevents the action of an agonist on a receptor or the subsequent response, but does not have an effect of its own, e.g. atropine and muscarine • inverse agonist: an agent which activates.

Ppt Pharmacodynamics Mechanism Of Drug Action Receptor Pharmacology Mechanism of drug action. 1. drugs can interact with receptors, ion channels, enzymes, and carrier molecules in cells. 2. receptor mediated mechanisms involve drugs binding to receptors, forming drug receptor complexes that trigger biological responses. non receptor mechanisms do not involve receptors. 3. Antagonism: when one drug decreases or abolishes the action of another, they are said to be antagonistic • effect of drugs a b < effect of drug a effect of drug b • usually in an antagonistic pair one drug is inactive as such but decreases the effect of the other • depending on the mechanism involved, antagonism may be • physical. Presentation transcript. introduction pharmacodynamics: study of the biochemical and physiologic effects of drugs and their mechanisms of action. drug action • the main ways by which drugs act are via interaction with cell proteins, namely receptors, ion channels, enzymes and transport carrier proteins.
