Oxybutynin is an antispasmodic medication commonly used to treat overactive bladder by relaxing the bladder muscles, which helps reduce urinary urgency, frequency, and incontinence. It works by inhibiting the activity of acetylcholine, a neurotransmitter responsible for bladder contractions. Oxybutynin can provide relief for individuals suffering from conditions that result in frequent urination or an uncontrollable urge to urinate, improving their quality of life.
