๐ฟ What is Mirabegron 50 mg (Mirago)?
Mirago 50 mg features Mirabegron, a first-in-class ฮฒ3-adrenoceptor agonist specifically designed to relax detrusor smooth muscle during bladder filling. This targeted mechanism increases bladder capacity and reduces involuntary contractions, delivering significant relief for patients suffering from the disruptive symptoms of OAB.
In clinical studies, the 50 mg dose of Mirabegron has been shown to reduce daily micturition frequency by up to 45% and decrease incontinence episodes by over 50% compared to placebo. Its favorable tolerability profileโlacking anticholinergic adverse effectsโmakes it an ideal option for those who cannot tolerate or do not respond adequately to muscarinic antagonists.
