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. 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. Pharmacodynamics refers to the effects of drugs in the body and the mechanism of their action. as a drug travels through the bloodstream, it exhibits a unique affinity for a drug receptor site, meaning how strongly it binds to the site. drugs and receptor sites create a lock and key system (see figure 1.1 [ 1 ]) that affect how drugs work and. Drug: a chemical agent that selectively interacts with specific target molecules (i.e. receptors) to alter their specific physiological functions. agonist: drug that activates receptors to result in either stimulation or inhibition of the function of various types of cells and organs. antagonist: drug that prevents receptor activation by agonists.

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.
