What Is Tolterodine ER Used For? -- An Overview
An overactive bladder is caused by bladder muscle
contractions that are too frequent and 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 bladder muscles contract spastically and frequently. This causes the following symptoms:
- Sudden, frequent urges to urinate
- Frequent urination (needing to go more than eight times in 24 hours)
- Leaking accidents (known as urinary incontinence or urge incontinence).
Sometimes, an overactive bladder is caused by other medical problems, such as an
enlarged prostate. In these cases, it is usually best to treat the underlying problem, instead of using
tolterodine ER. The medication is not approved for other types of
bladder problems.
How Does Tolterodine ER Work?
As mentioned, tolterodine ER belongs to a group of medications known as anticholinergics or antimuscarinics. It 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 due to bladder muscle contractions that are too frequent and uncontrollable, tolterodine ER can help relieve many of the associated symptoms.
