Summary • Basic Principles of Pharmacodynamics • Mechanisms of drug action – Enzymes, Ion channels, Transporters and Receptors with examples • Definitions of affinity, efficacy, agonist and antagonists etc. General Outline. ADVERTISEMENTS: This article throws light upon the four main types of receptors. Ligand binding produces physical changes in, ? - DRUG TREATMENT OF PSYCHOSIS www.psychiatricnursingfmcon.yolasite.com Pharmacokinetics Metabolism Most antipsychotics are almost completely metabolized. Eugene Serebryany. 15. Drug action via a direct effect on a receptor 1.2. 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. • Drug transducer mechanisms • GPCR and different GPCR transducing mechanisms – cAMP, Protein kinase etc. Drugs may be considered a full agonist , partial agonist, or antagonist, depending upon the type of drug interaction with the receptor and the resulting pharmacodynamic response (see discussion below).

Receptors have a life cycle (as other proteins, Receptors can up-regulate increase in numbers, Down-regulate decrease in numbers (chronic, Some drugs and many natural ligands such as, Full agonist Produces the maximal responce, Partial agonist (agonist-antagonist or mixed, In the presence of full agonist, a partial, chemical antagonism (interaction in solution), pharmacokinetic antagonism (one drug affecting, competitive antagonism (both drugs binding to the, interruption of receptor-effector linkage, physiological antagonism (two agents producing, The relationship between the concentration of, Depending on the purpose of the the studies, this, In this relationship percentage of a maximal. Pharmacokinetics is “what the body does to the”. Pharmacokinetics (PK) refers to the movement of drugs through the body, whereas pharmacodynamics (PD) refers to the body’s biological response to drugs.
