Trospium chloride

Brand names: Sanctura

Why is Trospium chloride prescribed?

Sanctura is prescribed for the treatment of overactive bladder (OAB) in adults. People with overactive bladder experience a strong and urgent need to urinate (urgency), a need to urinate more often than normal (frequency), or uncontrolled urine leakage (incontinence).

In OAB, the muscle in the bladder wall spasms, causing a need to urinate even when the bladder is not full. It can also result in accidental urination. Sanctura blocks the signal that causes spasm, relaxing the muscle of the bladder wall and restoring more normal bladder function.

Special warnings about Trospium chloride

Sanctura should be used with caution if you have trouble emptying your bladder. Before taking Trospium chloride, make sure the doctor knows if you have liver or kidney disease, stomach or intestinal problems, severe constipation, ulcerative colitis, myasthenia gravis, or eye problems such as glaucoma. Sanctura may make these conditions worse.
