Mirbeg-S 25 Combo Pack is a prescription-only medication comprising a fixed-dose combination of Mirabegron (25mg) and Solifenacin (5mg) for the management of symptoms associated with overactive bladder (OAB). The product is designed to provide relief from urinary frequency, urgency, and incontinence, as well as nocturia, a common OAB symptom characterized by nighttime awakenings to void. Mirabegron, an β3-adrenergic receptor agonist, works by relaxing the bladder muscles, increasing bladder capacity, and improving urinary flow. Solifenacin, a muscarinic receptor antagonist, inhibits the activity of the muscarinic receptors in the bladder, reducing the contractions that can lead to urgency and incontinence. The combination of these two agents in Mirbeg-S 25 Combo Pack offers a unique mechanism of action, addressing both the functional and anatomical aspects of OAB. As directed, the product is taken orally once daily, providing consistent and sustained relief from OAB symptoms for up to 24 hours.
