Mirabegron

Mirabegron

Mirabegron is a selective β3 adrenoreceptor agonist approved for the treatment of urgency, urge incontinence, and increased urination frequency associated with overactive bladder. It acts on the urinary bladder by activating β3 receptors in sympathetic nerve endings of the detrusor muscle, causing it to relax. This relaxation allows the bladder wall to distend as the bladder fills with urine.

Tachycardia and urinary tract infections are the most common side effects of mirabegron.
