Mirabegron is a once-daily beta-3 adrenoceptor agonist for the symptomatic treatment of urgency, frequency and/or urgency incontinence which is now available for the treatment of OAB.
Antimuscarinic agents such as Oxybutynin, Vesicare and Toviaz are the current treatment standard but doctors will now be able to offer patients an alternative new treatment that works in a different way.
Mirabegron has a completely different mechanism of action to antimuscarinics. It works by stimulating the beta-3 receptors in the muscle of the bladder causing relaxation of the bladder muscle and improving storage capacity of the bladder without impeding bladder voiding.
Potential Side Effects
In the three 12 week, Phase III studies, the most common adverse reactions reported for Mirabegron 50mg were tachycardia (a faster than normal heart rate) (1.2%) and urinary tract infections (2.9%). More serious adverse reactions include artrial fibrillation.
For further information we suggest you contact your GP and if possible, take a bladder diary with you to show him/her the measurements and frequency of voiding.
