Tarafenacin is primarily used in the treatment of overactive bladder (OAB) syndrome. It works by blocking muscarinic receptors in the bladder, which helps reduce involuntary bladder contractions. This action increases bladder capacity and decreases the frequency and urgency of urination. It is particularly beneficial for patients who experience symptoms such as frequent urination, sudden urges to urinate, and urinary incontinence. Tarafenacin is often prescribed when lifestyle changes and other treatments have not provided sufficient relief. Its targeted mechanism helps improve the quality of life for individuals suffering from OAB by providing better control over bladder function.
