What Is Mirabegron Used For?

Mirabegron is prescribed to treat symptoms of an overactive bladder in adults. It has been shown that using mirabegron can help reduce leaking accidents and prevent people from having to urinate as often. It works by binding to a certain receptor in the bladder, which helps the bladder muscle relax. As a result, the bladder can fill more fully and store more urine.

An Overview of Uses for Mirabegron

Mirabegron (Myrbetriq™) is a prescription medication approved to treat symptoms of an overactive bladder. It is the first medicine in a class of drugs known as beta-3 adrenergic agonists.

Mirabegron Use for an Overactive Bladder

An overactive bladder (also known as urge incontinence) is a condition that occurs when people cannot control their bladder muscles. It is estimated that this conditions affects 33 million people in the United States.
Normally, the bladder fills slowly until nerve signals tell your brain the bladder is full and that you need to use the bathroom. During urination, muscles in the bladder contract or tighten, forcing urine out of the bladder. At the same time, muscles surrounding the urethra (the tube that carries urine out of the body) relax and let the urine pass through. In people with an overactive bladder, the bladder muscles contract too often and without warning.
Because of these frequent and involuntary contractions, people with an overactive bladder have sudden, frequent urges to urinate (urinary urgency). These urges can lead to leaking accidents, known as urge incontinence. People with an overactive bladder also urinate too often throughout the day (known as urinary frequency).
Mirabegron is one of several different treatment options available to treat an overactive bladder. Like most other treatments, the drug can help reduce the symptoms of an overactive bladder but will not provide a cure. Most people will continue to have some symptoms, even with treatment.
