The beta 3 adrenergic receptor was discovered in the late 1980s and initially beta3AR agonists were investigated as treatment for obesity and diabetes. A number of compounds were tested in clinical trials but didnt show sufficient benefits in these areas.Since the 2000s there is evidence that there are beta3AR on the detrusor muscle of the bladder. The detrusor muscle contracts during urination and remains relaxed to allow the bladder to store urine. Mirabegron was the first FDA approved selective agonist approved to treat overactive bladder (OAB).Vibegron is a selective beta3AR agonist that is developed in Japan by Kyorin Pharmaceutical Co., Ltd and Kissei Pharmaceutical Co.,Ltd and Urovant Sciences to treat overactive bladders  and pain caused by irritable bowel syndrome.
