Begron (Mirabegron) is a medication used in the management of overactive bladder. It is in the sympathomimetic class of medications which received approval from the US Food and Drug Administration (FDA) in June 2012 for treating overactive bladder with symptoms of urge urinary incontinence, urgency, and urinary frequency.
Begronrelaxes the muscles of the bladder to reduce the need to urinate frequently or urgently. It works by activating beta-3 adrenergic receptors, which causes the detrusor muscles of the bladder to relax. This increases the amount of urine the bladder can hold, and reduces the frequency and urgency of urination.
