Meladrazine is a drug used in urology as an antispasmodic. Meladrazine acts on the central nervous system as a polysynaptic inhibitor. Its usefulness in treating spasticity in patients with multiple sclerosis is well known. As many of these patients have bladder problems, a coincidental beneficial effect on uninhibited bladders has been discovered. Meladrazine caused a high incidence of side effects; therefore, treatment with terodiline separately is recommended for geriatric patients who have severe motor urge incontinence.
