Myrbetriq (generic name: mirabegron) is a new drug that is primarily prescribed to treat the symptoms of an
overactive bladder, including incontinence (loss of bladder control), a strong need to urinate right away, or a frequent need to urinate. It may also be prescribed to treat neurogenic detrusor overactivity, a bladder dysfunction frequently observed in children with conditions such as multiple sclerosis (MS) and spinal cord injury (SCI).
Mirbagron acts on receptors in the bladder (
beta-3 adrenergic receptors). Activating these receptors leads to the relaxation of the bladder and the relief of the symptoms characteristic of an overactive bladder.
Studies have reported that mirabegron or other selective β3‐Adrenergic Receptor (β3AR) agonists could help treat humans by promoting adipose tissue (AT) “beiging,” which could perhaps help in the treatment of metabolic disorders like obesity and type 2 diabetes (T2D)

Overactivity of the bladder is a common condition that crops up in old age but may appear at any age. Overactive bladder is a condition in which bladder muscles contract uncontrollably and cause frequent urination. This creates an urgent need to urinate and an inability to control urination in adults.
Both men and women can suffer from this condition, but women tend to suffer more often than men. The symptoms of this phenomenon are frequent urination both day and night and a sudden urge to urinate that is difficult to control.
In children three years of age and older, the condition known as neurogenic detrusor overactivity produces a loss of bladder control caused by brain, spinal cord, or nerve problems or multiple sclerosis.
