A receptor antagonist is a type of receptor ligand or drug that blocks or dampens a biological response by binding to and blocking a receptor rather than activating it like an agonist. Antagonist drugs interfere in the natural operation of receptor proteins. [1]

en.wikipedia.org/wiki/Receptor_antagonistNeutral antagonists block the effect of an agonist. There are two types of antagonism: competitive (reversible, surmountable) and non-competitive (irreversible, insurmountable). For example, naloxone is a competitive antagonists at all opioid receptors and ketamine is a non-competitive antagonist at the NMDA-glutamate receptor.
academic.oup.com/bjaed/article/4/6/181/314691The majority of pharmacological antagonists work to block receptors at their structurally specified binding sites by out-competing endogenous ligands or substrates. An example of a competitive antagonist is the interleukin-1 receptor antagonist, IL-1Ra.
link.springer.com/referenceworkentry/10.1007/978 …Receptor antagonists are inhibitors of receptor activity. Antagonists mimic ligands that bind to a receptor and prevent receptor activation by a natural ligand. Receptor antagonists can be classified as reversible or irreversible.
www.sciencedirect.com/topics/medicine-and-dentis…A receptor antagonist is a type of receptor ligand or drug that does not provoke a biological response itself upon binding to a receptor, but blocks or attenuates agonist-mediated responses. In pharmacology , antagonists have affinity but no efficacy for their cognate receptors and binding will disrupt the interaction and inhibit the function ...

Competitive
Competitive antagonists bind to receptors at the same binding site (active site) as the endogenous ligand or agonist, but without activating the receptor. Agonists and antagonists "compete" for the same binding site on the … 展开Many antagonists are reversible antagonists that, like most agonists, will bind and unbind a receptor at rates determined by receptor-ligand kinetics.
