Table of contents:

Comtan is a medication used in conjunction with levodopa/carbidopa to treat the symptoms of Parkinson's disease. The active ingredient in Comtan is Entacapone. Entacapone works by inhibiting catechol-O-methyltransferase (COMT), an enzyme that breaks down levodopa in the body.

Entacapone helps treat symptoms of end of dose "wearing-off" that some people experience when taking carbidopa/levodopa. By inhibiting COMT, entacapone helps to increase and prolong the effect of levodopa in the brain, and can improve motor symptoms such as tremors, stiffness, and slowness of movement. Comtan is available as tablets containing 200 mg of entacapone.

Uses and Dosage

Comtan (Entacapone) comes as a tablet to be taken orally, either with or without food. It is typically taken with each prescribed dose of levodopa/carbidopa (up to 8 times daily), or as directed by your physician. Take Comtan regularly to receive the maximum benefits, and to take it at a consistent time each day to ensure that you remember to take it. Do not discontinue usage suddenly unless advised to do so by your healthcare provider, as this may result in the worsening of Parkinson's symptoms.

The recommended dosage is based on your medical condition, liver function, and response to therapy. However, the typical dose of Comtan tablet is 200 mg by mouth taken with each dose of carbidopa/levodopa. Do not take more than 1,600 mg (8 tablets) in a day.
