Myrbetriq is a prescription medication that contains the synthetic compound mirabegron. It is classified as a beta-3 adrenergic receptor agonist used to treat overactive bladder symptoms. The drug is absorbed orally and reaches peak plasma concentrations within a few hours after ingestion. Mirabegron binds selectively to beta-3 receptors on the detrusor muscle of the urinary bladder. Activation of these receptors leads to relaxation of the bladder smooth muscle, increasing bladder capacity. This relaxation reduces the frequency and urgency of involuntary bladder contractions. The sustained pharmacological effect contributes to improved storage function of the urinary tract. Clinical studies have demonstrated that Myrbetriq decreases the number of urge incontinence episodes and nocturnal voids.

Myrbetriq is a prescription medication that contains the active ingredient mirabegron. It is indicated for the treatment of overactive bladder in adults. The drug works by acting as a selective agonist on beta-3 adrenergic receptors in the urinary tract. Activation of these receptors leads to relaxation of the detrusor muscle and increased bladder capacity. This physiological effect reduces urgency and frequency of urination associated with the condition. Overall Myrbetriq provides symptomatic relief without directly influencing bladder sensory pathways.

Myrbegron may cause headache in some patients. It can lead to infections of the urinary tract. Nasopharyngitis is reported as a frequent adverse effect. Increases in blood pressure have been observed during treatment. Some users experience bronchitis or other respiratory infections. Dizziness may occur, especially when standing quickly. Nausea and diarrhea are also listed among common reactions. Fatigue sometimes accompanies the above symptoms.
