Blocking receptors
 - Wikipedia)
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. They are sometimes called blockers; examples include … See more The English word antagonist in pharmaceutical terms comes from the Greek ἀνταγωνιστής – antagonistēs, "opponent, competitor, villain, enemy, rival", which is derived from anti- ("against") and … See more Efficacy and potency By definition, antagonists display no efficacy to activate the receptors they bind. Antagonists do not maintain the ability to activate a receptor. Once bound, however, antagonists inhibit the function of agonists, inverse agonists, … See more Many antagonists are reversible antagonists that, like most agonists, will bind and unbind a receptor at rates determined by See more • Media related to Receptor antagonists at Wikimedia Commons See more Biochemical receptors are large protein molecules that can be activated by the binding of a ligand such as a hormone or a drug. … See more Competitive Competitive antagonists bind to receptors at the same binding site (active site) as the endogenous ligand or agonist, but without activating the receptor.
