Megatas 50 Tablet belongs to the group of medications called ‘urinary antagonists' or 'antispasmodics' primarily used to treat overactive bladder (OAB) symptoms. Overactive bladder is a condition in which the urinary bladder muscles constrict uncontrollably, thereby causing an urgent need to urinate, frequent urination, and an inability to control urination.

Megatas 50 Tablet contains ‘mirabegron’ that relaxes the urinary bladder muscles, which in turn decreases the activity of the overactive bladder. In an overactive bladder, muscle contractions occur before the full expansion of the bladder, causing the patient to have frequent urges to urinate. Megatas 50 Tablet stops these sudden contractions of urinary bladder muscles, thereby enabling control over urination. Thus, it increases the amount and volume of urine that can be held by the bladder.

Overactive bladder (OAB): In normal conditions, when the urinary bladder is filled with urine, it sends a message to the brain that an individual is ready to urinate. During the urination process, bladder muscles contract, which ultimately leads to a uniform flow of urine. Contrary to this, in an overactive bladder (OAB), the urinary bladder muscles start contracting before the urine is filled in the urinary bladder, thereby causing frequent urges to urinate.
