Tasmar

Tasmar is a medication commonly used for treating Parkinson's disease. It must be used in combination with carbidopa-levodopa products, as it is not effective at treating Parkinson's disease without the use of levodopa. This prescription medication works by increasing blood levels of levodopa, helping it last longer in the body. Possible side effects of Tasmar include nausea, sleep problems, and involuntary movements.

 

What Is Tasmar?

Tasmar® (tolcapone) is a prescription medication used to treat Parkinson's disease. It is always used in combination with carbidopa-levodopa products (Sinemet®, Sinemet CR, or Parcopa®), as it is not effective at treating Parkinson's disease without the use of levodopa. Tasmar is useful for people who experience otherwise uncontrollable fluctuations in their symptoms, such as "wearing off" of their carbidopa-levodopa before each dose.
 
Due to the risk of potentially fatal liver failure that is sometimes caused by Tasmar, people should only use the drug if other alternatives are not acceptable or do not work.

Who Makes Tasmar?

Tasmar is made by Orion Corporation, Inc. and marketed by Valeant Pharmaceuticals International.
 

How Does Tasmar Work?

Tasmar is always used in combination with carbidopa and levodopa; it is not effective at treating Parkinson's disease when used alone. The drug works by increasing blood levels of levodopa and helping it last longer in the body. Tasmar works by inhibiting an enzyme known as catechol-O-methyltransferase (COMT) that breaks down levodopa before it has a chance to reach the brain.
 

Effects of Tasmar

In clinical studies, Tasmar (with carbidopa-levodopa) was shown to be more effective than just carbidopa-levodopa for Parkinson's treatment. In these studies, people who were experiencing wearing-off fluctuations of their carbidopa-levodopa therapy were given either Tasmar or a placebo (a "sugar pill" that does not contain any active ingredients) to take with each dose of their carbidopa-levodopa. These studies showed that Tasmar helped the carbidopa-levodopa to work longer, with shorter "off" periods (when the medication did not work well) and longer "on" periods (when the medication did work well).
 
Although studies have also shown that adding Tasmar is useful for people who are not experiencing problems with wearing-off or other symptom fluctuations, the drug is not recommended for such people, as the risks of using it (especially liver failure) outweigh the potential benefits.
