HOW DOES GEMTESA WORK?
GEMTESA (vibegron) is not an anticholinergic treatment—it works differently by selectively targeting beta-3 adrenergic receptors to reduce OAB symptoms1
Bladder relaxation is predominantly mediated by beta-3 adrenergic receptors1,2
M3 (muscarinic) receptorActivating the muscarinic receptors contracts the bladder detrusor muscle to mediate bladder emptying2
Beta-3 receptorActivating the beta-3 adrenergic receptors relaxes the bladder detrusor muscle to increase capacity1-3


GEMTESA is a selective beta-3 adrenergic agonist1,4
