How does Gemtesa (vibegron) work?

Official answer


Gemtesa (vibegron) works by relaxing the detrusor muscle of the bladder – this is smooth muscle found in the wall of the bladder – and it does this by activating beta-3 adrenergic receptors located in the detrusor muscle. By activating these receptors, the muscle in the bladder wall relaxes. This allows the bladder to hold more urine, which can relieve symptoms of overactive bladder such as needing to pass urine immediately or frequently (urinary urgency and frequency) and reduce urine leakage (urinary incontinence).
