Effectiveness

How Entacapone Affects PatientsEntacapone is a drug used to treat Parkinson's disease that is similar to another drug called tolcapone, but does not have the same risk of causing liver damage. Entacapone blocks an enzyme (COMT) that is found in many organs in the body and helps to break down certain substances, like dopamine and levodopa. By blocking this enzyme, entacapone helps to increase the levels of levodopa in the body for longer, which reduces Parkinson's symptoms.
How Entacapone works in the bodyEntacapone works by blocking an enzyme that breaks down levodopa, a medication used to treat Parkinson's. When entacapone is taken with levodopa and an aromatic amino acid decarboxylase inhibitor, it boosts the effectiveness of the levodopa. This helps to more consistently reduce the symptoms of Parkinson's.

Entacapone for Parkinson's Disease
This medication has some pretty unpleasant side effects, but it does seem to help with my motor skills. I've only taken it a few times, and I've already experienced muscle cramping, mood swings, and blurred vision.

I'm not thrilled with how much this drug costs my Medicare Advantage company every month. It's outrageous that it's so expensive, especially since it's made in Finland.

What class of drug is entacapone?

Answered by AI

What is the purpose of entacapone?

"Entacapone is a drug used to treat the "wearing off" effect in patients with [Parkinson's disease](https://www.withpower.com/clinical-trials/parkinson's-disease). Parkinson's disease is a disorder of the central nervous system."

Answered by AI

What is the mechanism of action of entacapone?

"Entacapone is believed to work by inhibiting COMT and changing the way levodopa is absorbed in the bloodstream."

Answered by AI

Is levodopa same as entacapone?

"This medicine contains entacapone, which helps levodopa last longer by blocking the COMT enzyme. COMT breaks down levodopa before it reaches the brain, but entacapone inhibits this action, allowing more levodopa to be available to the brain."
