From Wikipedia, the free encyclopedia

In the field of pharmacology, a superagonist is a type of agonist that is capable of producing a maximal response greater than the endogenous agonist for the target receptor, and thus has an efficacy of more than 100%.^[1]^[2] For example, goserelin is a superagonist of the gonadotropin-releasing hormone receptor.
