Chemistry:Uncompetitive antagonist
From HandWiki
Uncompetitive antagonists differ from non-competitive antagonists in that they require receptor [citation needed] activation by an agonist before they can bind to a separate allosteric binding site. This type of antagonism produces a kinetic profile in which "the same amount of antagonist blocks higher concentrations of agonist better than lower concentrations of agonist".[1] Memantine, used in the treatment of Alzheimer's disease, is an uncompetitive antagonist of the NMDA receptor.[2]
