TiPS – December 1998 (Vol. 19) 515 It would be useful to have a book on the principles of drug–receptor interaction to which students could refer, and Kenakin’s book asks many The interaction of a drug with a receptor can produce a range of different types of effects. The types of interactions that can occur are shown graphically below.

The bond is reversible and typical of most drug-receptor interactions. Since a drug usually attaches to its site of action by multiple contacts, several of the types of bonds described below may participate. Electrostatic attraction (A). A positive and negative charge attract each other. Ionic interaction: An ion is a particle charged either positively (cation) or negatively (anion), i.e., the Pharmacodynamics (sometimes described as what a drug does to the body) is the study of the biochemical, physiologic, and molecular effects of drugs on the body and involves receptor binding (including receptor sensitivity), postreceptor effects, and chemical interactions.

The interaction of a drug with a receptor can produce a range of different types of effects. The types of interactions that can occur are shown graphically below. The interaction of a drug with a receptor generates a code of information having components of affinity and efficacy. How this information is translated into a response depends on the unique cells, tissue, organ or system in which the receptor resides. This book describes how to analyze various

The interaction of drugs with receptors is highly specific. Examine these drug structures and the receptors at which the drugs act. Notice how slight structural modifications result in significant differences in receptor interactions. The drug-receptor reaction is essentially an exchange of the hydrogen bond between a drug molecule, surrounding water, and the receptor site. Finally hydrophobic bonds are formed between non-polar hydrocarbon groups on the drug and those in the receptor site.

Drug and receptor interaction is an important field of study in medicine. Knowing the chemistry behind these interactions leads to understanding how drugs work in the treatment of different ailments.

Receptors determine the quantitative relationship between dose or concentration of the drug and the A relationship between available drug concentration and the proportion of receptors occupied was quickly advanced which implied that drug-receptor interactions obey mass action principles, in a manner analogous to enzyme-substrate interactions.

A minimum three point attachment of a drug to a receptor site is required. Receptors vary greatly in structure so a specific chemical structure is required for the receptor site and a complementary drug structure. Classification of Drugs Based on Drug-Receptor Interactions: A drug that binds to a receptor and produces a biological response is an agonist. Thus, an agonist has the properties of affinity and intrinsic activity. A drug that binds to a receptor but does not initiate a cellular response is an antagonist. In other words, an antagonist has the property of affinity but not of intrinsic activity

    • Describe two types of drug interaction and explain how they might affect drug response and safety. 28 Practical Pharmacology for the Pharmacy Technician Safe and effective drug treatment is not only a function of the physical and chemical prop-erties of drugs, but also a function of how the human body responds to the administration of medication. The study of the bodily processes that Agonists/Antagonists Full Partial Direct/Competitive Indirect/Noncompetitive Inverse A single drug can bind to a single receptor and cause a mix of effects (agonist, partial agonist, inverse agonist, antagonist) Functional Selectivity Hypothesis: Conformational change induced by a ligand-receptor interaction may cause differential functional activation depending on the G-protein and other

    Receptor theory: A receptor is a component of a cell or oganism that interacts with drugs which results in a sequence of events which lead to an observed change in function. Receptors determine the quantitative relationship between dose or concentration of the drug and the The drug-receptor reaction is essentially an exchange of the hydrogen bond between a drug molecule, surrounding water, and the receptor site. Finally hydrophobic bonds are formed between non-polar hydrocarbon groups on the drug and those in the receptor site.

Learn vocabulary, terms, … The bond is reversible and typical of most drug-receptor interactions. Since a drug usually attaches to its site of action by multiple contacts, several of the types of bonds described below may participate. Electrostatic attraction (A). A positive and negative charge attract each other. Ionic interaction: An ion is a particle charged either positively (cation) or negatively (anion), i.e., the
