Myrbetriq is FDA-approved for the treatment of overactive bladder (OAB) in adults, including symptoms of urinary urgency, increased frequency, and urge incontinence. It may be used as monotherapy or in combination with other OAB medications.
Myrbetriq is a beta-3 adrenergic agonist. It activates beta-3 receptors in the detrusor muscle of the bladder, causing relaxation of the smooth muscle. This increases bladder capacity and storage without affecting the voiding contraction, reducing OAB symptoms.
Common side effects may include hypertension, nasopharyngitis, and urinary tract infections. Patients with severe uncontrolled hypertension should not use this medication. It may interact with certain drugs metabolized by CYP2D6. Patients should inform their healthcare provider of their complete medical history before starting treatment.
