Mirabegron extended-release tablets are a beta-3 adrenergic agonist indicated for the treatment of: Overactive bladder (OAB) in adult patients with symptoms of urge urinary incontinence, urgency, and urinary frequency. ( 1.1 ) Neurogenic detrusor overactivity (NDO) in pediatric patients aged 3 years and older and weighing 35 kg or more. ( 1.2 ) 1.1 Adult Overactive Bladder (OAB) Mirabegron Monotherapy Mirabegron extended-release tablets are indicated for the treatment of OAB in adult patients with symptoms of urge urinary incontinence, urgency, and urinary frequency. 1.2 Pediatric Neurogenic Detrusor Overactivity (NDO) Mirabegron extended-release tablets are indicated for the treatment of NDO in pediatric patients aged 3 years and older and weighing 35 kg or more.

Mirabegron extended-release tablets are contraindicated in patients with known hypersensitivity reactions to mirabegron or any inactive ingredients of the tablet [see Adverse Reactions ( 6.1 , 6.2 )]. Hypersensitivity to mirabegron or any inactive ingredients. ( 4 )

Increases in Blood Pressure: Can increase blood pressure in adult or pediatric patients. Periodically monitor blood pressure, especially in hypertensive patients. Mirabegron extended-release tablets are not recommended in patients with severe uncontrolled hypertension. ( 5.1 ) Urinary Retention in Patients with Bladder Outlet Obstruction and in Patients Taking Muscarinic Antagonist Drugs for Overactive Bladder: Administer with caution in these patients because of risk of urinary retention. ( 5.2 ) Angioedema: Angioedema of the face, lips, tongue and/or larynx has been reported with mirabegron. ( 5.3 , 6.2 ) 5.1 Increases in Blood Pressure Increases in Blood Pressure in Adults Mirabegron can increase blood pressure. Periodic blood pressure determinations are recommended, especially in hypertensive patients. Mirabegron is not recommended for use in patients with severe uncontrolled hypertension (defined as systolic blood pressure greater than or equal to 180 mm Hg and/or diastolic blood pressure greater than or equal to 110 mm Hg) [see Clinical Pharmacology ( 12.2 )] . In two, randomized, placebo-controlled, healthy adult volunteer studies, mirabegron was associated with dose-related increases in supine blood pressure. In these studies, at the maximum recommended dose of 50 mg, the mean maximum increase in systolic/diastolic blood pressure was approximately 3.5/1.5 mm Hg greater than placebo. In contrast, in adult OAB patients in clinical trials, mirabegron, taken as …

8.1 Pregnancy Risk Summary There are no studies with the use of mirabegron in pregnant women or adolescents to inform a drug-associated risk of major birth defects, miscarriages, or adverse maternal or fetal outcomes. Mirabegron administration to pregnant animals during organogenesis resulted in reversible skeletal variations (in rats) at 22-fold (via AUC) the maximum recommended human dose (MRHD) of 50 mg/day and decreased fetal body weights (in rabbits) at 14-fold the MRHD. At maternally-toxic exposures in rats (96-fold), decreased fetal weight and increased fetal mortality were observed and, in rabbits (36-fold), cardiac findings (fetal cardiomegaly and fetal dilated aortae) were …
