It can help identify which patients are most likely to respond to treatment.Indeed, this method is used to create new drugs. By knowing the interaction between a certain site of a drug and a receptor, other drugs can be formulated in a way that replicates this interaction, thus producing the same therapeutic effects.Drugs disrupting the cytoplasmic membrane or electron transport chain, for example, are more likely to cause toxicity problems than those targeting components of the cell wall ( peptidoglycan or β-glucans) or 70S ribosome, structures which are absent in human cells. In the case of anti-infective drug development, the information permits anticipation of problems relating to clinical safety.In contrast, a mode of action (MoA) describes functional or anatomical changes, at the cellular level, resulting from the exposure of a living organism to a substance.Įlucidating the mechanism of action of novel drugs and medications is important for several reasons: Common examples of drugs that work in this way are antacids and laxatives. Receptor sites have specific affinities for drugs based on the chemical structure of the drug, as well as the specific action that occurs there.ĭrugs that do not bind to receptors produce their corresponding therapeutic effect by simply interacting with chemical or physical properties in the body. A mechanism of action usually includes mention of the specific molecular targets to which the drug binds, such as an enzyme or receptor. In pharmacology, the term mechanism of action ( MOA) refers to the specific biochemical interaction through which a drug substance produces its pharmacological effect. Beta blockers exert their pharmacological effect, decreased heart rate, by binding to and competitively antagonising a type of receptor called beta adrenoceptors.
