Pharmacodynamics (drug receptor interactions): power point presentation
This document has been uploaded to Scribd by Dr. Robert L. Copeland, Pharmacology Professor at Howard University. It deals with basic principles of pharmacodynamics like: Concept of specific drug receptors, Receptor Types, Ion-channel-linked receptors, G-protein-linked receptors, Enzyme-linked receptors, Intracellular receptors, Log Dose-Response Curve, Agonists (or Full Agonists), additivity and sinergism. You can download the power […]
Efficacy definition in pharmacodynamics
Pharmacodynamics definition of efficacy.
Potency of a drug. Equipotent drug definition
The following pharmacology definition has been taken from the Pharmacology and Experimental Therapeutics Department Glossary at Boston University School of Medicine. Equipotent: Equally potent, or equally capable of producing a pharmacologic effect of a specified intensity. The masses of the drugs required to produce this degree of effect may be compared, quantitatively, to
Pharmacodynamics definitions. Receptor desensitization
The following pharmacological definition has been taken from the Pharmacology and Experimental Therapeutics Department Glossary at Boston University School of Medicine. Desensitization: A decline in the response to repeated or sustained application of an agonist that is a consequence of changes at the level of the receptor. The copyright of the text is hold by […]

Pharmacodynamics topics. What is affinity?
The following pharmacological definition has been taken from the Pharmacology and Experimental Therapeutics Department Glossary at Boston University School of Medicine. Affinity: The equilibrium constant of the reversible reaction of a drug with a receptor to form a drug-receptor complex; the reciprocal of the dissociation constant of a drug-receptor complex. Under the most general conditions, […]
