Effectiveness
How Comtan Affects PatientsEntacapone is a drug used to treat Parkinson's disease when used in combination with other medicines. It works by blocking an enzyme (COMT) found in the liver, kidneys, heart, lungs, muscles, and other parts of the body. COMT breaks down dopamine and other chemicals, so blocking it allows the dopamine to remain active longer. When a decarboxylase inhibitor is present, COMT becomes the main enzyme responsible for breaking down the medicine levodopa.
How Comtan works in the bodyEntacapone works with levodopa and other drugs to help people with Parkinson's disease. It blocks an enzyme called COMT, which breaks down levodopa in the bloodstream. This helps keep the levodopa in the body longer, meaning it can provide more constant relief from symptoms.

Comtan Reviews: What are patients saying about Comtan?
5Patient Review
4/27/2008 I started having hallucinations that were really scary and real to me. I would see faces in my plants, bikes driving around my property, and trucks backing through my bedroom window.
5Patient Review
7/31/2008 Though it causes a feeling of "fogginess," this prescription helps alleviate symptoms.
4.3Patient Review
3/13/2012 Sinemet just wasn't cutting it for me. Comtan, on the other hand, worked like a charm! I could walk and didn't have any constipation issues. The only downside is that I've had diarrhea ever since starting Comtan.
4.3Patient Review
9/1/2012 I began taking Comtan as directed, and it did wonders for my tremor and overall mood. However, after about three months of use, I started experiencing persistent diarrhea. This has been a real hindrance to enjoying the benefits of the drug.
4.3Patient Review
12/5/2013 This medication has been a godsend for me. It's helped control my Parkinson's quite well, and I'm currently in the process of increasing my dosage.
