Mirabegron
Mirabegron, sold as Myrbetriq, is the only product on this shelf. It comes in 25 mg and 50 mg tablets for Overactive Bladder.
Key points
- Mirabegron is a beta-3 adrenergic agonist used alone or with solifenacin to treat overactive bladder in adults and neurogenic detrusor overactivity in children aged 3 and older.
- Blood pressure may rise during treatment, so your doctor will check it regularly while you take mirabegron.
- The medicine controls symptoms of overactive bladder but does not cure the condition.
How does Mirabegron work?
Mirabegron relaxes the detrusor muscle, the main muscle in the bladder wall, so the bladder can hold more urine before sending a signal to empty. This reduces the sudden urge and frequency that characterise overactive bladder.
Unlike older anti-muscarinic medicines, mirabegron does not affect the receptors in the salivary glands, so dry mouth is six-fold less common. For anyone looking at Bladder Health options, this difference in side effects is a practical one.
