Myrbetriq (Mirabegron) is a prescription medication for adults used to treat certain bladder problems (overactive bladder, neurogenic detrusor overactivity). Mirabegron is a type of medicine called a beta-3-adrenergic-receptor agonist, an alternative OAB treatment to antimuscarinics. It works by relaxing a certain bladder muscle (detrusor), which helps the bladder hold more urine and lessens symptoms of overactive bladder. Other alternative drugs include Vesicare, Ditropan, Toviaz.
In a study (A Prospective, Randomized, Placebo-Controlled Pilot Study of Mirabegron (Myrbetriq) and Behavioral Modification for Overactive Bladder in Parkinson Disease (908), April 14, 2020), P Agarwal, T Brown, S Ray, A Madan, I Roy-Faderman, found that “Mirabegron was safe and well-tolerated in this PD (Parkinson disease) population.”
In another clinical trial (STOMp: sexual function trial of overactive bladder medication, January 12, 2023), Allison Polland, MD, found that “Female sexual function has been shown to improve with overactive bladder (OAB) treatment”.
