Mirabegron
Mirabegron (often known by the brand Betmiga) is a medication used to treat symptoms associated with Overactive Bladder. It serves as an effective option for those seeking to regain control over bladder function. Myrbetriq is the one product listed, available as a prolonged-release tablet.
Key points
- As a beta-3 adrenergic agonist, it relaxes the bladder wall muscle to increase how much urine it can hold.
- By easing involuntary bladder contractions, it reduces the sudden urges and frequency associated with an overactive bladder.
- Because it can raise blood pressure in some people, blood pressure readings are checked before treatment starts.
- Increased heart rate, headache and dry mouth are typical early effects that tend to settle as the body adjusts.
What is Mirabegron?
Mirabegron is a beta-3 adrenergic agonist. It acts specifically to relax the detrusor muscle of the bladder wall. By increasing the bladder’s storage capacity, it reduces the involuntary contractions that lead to sudden urges.
What Mirabegron is used for
This medication is primarily indicated for the management of Overactive Bladder. It addresses symptoms such as the urgent need to urinate, increased frequency, and urge incontinence. Management of these symptoms is often categorised under Bladder Health.
How does Mirabegron work?
The medication stimulates specific receptors located in the bladder muscle. This activation allows the bladder to hold more urine before the signal to empty is sent to the brain, effectively easing the urge to go frequently.
Mirabegron brands and forms
Available in a prolonged-release tablet form, this preparation is designed for convenience and consistent coverage throughout the day. While commercial supply involves specific brand names such as Betmiga and Myrbetriq, the active chemical ingredient remains the same across these options.
