What Is Trospium Used For?
Trospium is used for relieving symptoms of an overactive bladder, such as frequent urination, frequent or sudden urges to urinate, and leaking accidents. The medication works by preventing the bladder muscles from contracting too frequently and uncontrollably (which occurs with an overactive bladder). At this time, there are no approved trospium uses for children.
Trospium chloride (Sanctura®) is a prescription medication approved for relieving overactive bladder symptoms. It belongs to a group of medications known as anticholinergics or antimuscarinics.
An overactive bladder is caused by muscle contractions that are too frequent and usually uncontrollable. Normally, the bladder slowly fills until nerve signals tell your brain that the bladder is full and you need to use the bathroom. Then the bladder muscles contract when you urinate. However, in some people, the muscles contract frequently and spastically. This causes the following symptoms:
- A frequent need to urinate (usually defined as needing to go more than eight times a day)
- Sudden, frequent urges to urinate
- Leaking accidents (known as urinary incontinence or urge incontinence).
Sometimes, an overactive bladder is caused by other medical problems, such as an enlarged prostate (also known as benign prostatic hyperplasia or BPH). In these cases, it is usually best to treat the underlying problem instead of using trospium. The medication is not approved for other types of bladder problems.
Trospium works by binding to specific receptors in the bladder, called muscarinic receptors, which helps the muscles of the bladder to relax. Since an overactive bladder is often caused by muscles that contract too frequently and uncontrollably, trospium can help relieve many of the associated symptoms.
