Myrbetriq, known generically as mirabegron, is a medication that has gained attention for its role in treating specific bladder conditions. This article explores what Myrbetriq is, how it works, its uses, and what patients need to know about it.
Understanding Myrbetriq
Myrbetriq belongs to a class of drugs called beta-3 adrenergic agonists. It works by relaxing the detrusor muscle in the bladder, which improves the bladder’s ability to store urine and reduces the frequency of urinary urgency and incontinence episodes.
Primary Use: Overactive Bladder (OAB)
The primary use of Myrbetriq is for the treatment of overactive bladder (OAB). OAB is characterized by a sudden urge to urinate that is difficult to control, frequent urination, and, in some cases, urge incontinence, where there is an involuntary loss of urine.
Patients with OAB often experience:
-
Urgency: A sudden and compelling need to urinate.
-
Frequency: Having to urinate more than eight times in 24 hours.
-
Nocturia: Waking up more than once in the night to urinate.
Myrbetriq helps manage these symptoms by relaxing the bladder muscle, allowing the bladder to hold more urine and reducing the frequency and urgency of urination.
Secondary Use: Neurogenic Detrusor Overactivity (NDO)
In addition to treating OAB, Myrbetriq has also been approved for use in patients with neurogenic detrusor overactivity (NDO). NDO is a bladder dysfunction caused by neurological conditions such as spinal cord injury or multiple sclerosis. In NDO, the bladder muscle contracts too often or at the wrong times, leading to similar symptoms as OAB. Myrbetriq’s muscle-relaxing effects help alleviate these symptoms, improving bladder control for patients with NDO.
Benefits of Myrbetriq
Myrbetriq offers several benefits for patients suffering from bladder conditions:
-
Improved Quality of Life: By reducing the symptoms of OAB and NDO, Myrbetriq helps patients regain control over their bladder, thereby improving their quality of life.
-
Convenient Dosage: Typically taken once daily, Myrbetriq provides a convenient treatment option for managing bladder issues.
-
Alternative to Anticholinergics: For patients who cannot tolerate anticholinergic medications (another class of drugs used to treat OAB), Myrbetriq provides an effective alternative.

Side Effects and Considerations
As with any medication, Myrbetriq may cause side effects. Common side effects include:
-
Increased blood pressure
-
Common cold symptoms (nasopharyngitis)
-
Urinary tract infection
-
Headache
Less common but more serious side effects can include severe allergic reactions, fast or irregular heartbeat, and angioedema (swelling of deeper layers of the skin).
Patients considering Myrbetriq should discuss their full medical history with their healthcare provider, particularly if they have hypertension, as Myrbetriq can raise blood pressure. Regular monitoring of blood pressure is recommended during treatment.
