Irreversible agonist

Irreversible agonist

An irreversible agonist is a type of agonist that binds permanently to a receptor in such a manner that the receptor is permanently activated. It is distinct from a mere agonist in that the association of an agonist to a receptor is reversible, whereas the binding of an irreversible agonist to a receptor is, at least in theory, irreversible. Oxymorphazone is an example of an irreversible agonist.[1] In practice, the distinction may be more a matter of degree, in which the binding affinity of an irreversible agonist is some orders of magnitude greater than that of an agonist.
