Comtan or Entacapone belongs to the class of drugs called nitrocatchols and is used to treat Parkinson’s disease. The drug Comtan is a COMT or catechol O methyl transferase inhibitor. Comtan, along with drugs like levodopa and carbidopa are used to treat symptoms such as poor muscle control, muscle spasms, tremors, and stiffness associated with Parkinson’s disease. Sometimes doctors use Comtan to treat other symptoms and conditions as well. When Comtan is used in conjunction with levodopa and carbidopa, levodopa levels in the body as well as the efficacy of the drug levodopa are maximized.
Conditions Treated by Comtan
Comtan is used to treat Parkinson’s disease and its different symptoms
a.) Typical dosage recommendations
If you are being treated for Parkinson’s disease, your doctor will recommend one 200 mg Comtan tablet to be taken with each and every dose of levodopa and carbidopa. You may have to take this up to 8 times (8 tablets) every day. If you suffer from Dyskinesia or cosume more than 800 mg of levodopa daily, your doctor may reduve the dosage of levodopa carbidopa. This is because Comtan maximizes the blood levels of levodopa carbidopa. You cannot and should not adjust your Comtan dose by yourself without the specific instructions from your doctor. Your doctor may increase or decrease your Comtan dosage depending on factors like other existing medical conditions, other medicines you consume and bothersome side effects.
b.)Missing a dose
If you for some reason have missed a dose, take it when you remember. If you forget to take your dose at the usual time and it is almost time for the next dosage, take the tablet at the next regular schedule and skip the missed dose. You should not consume additional Comtan pills to compensate for missed doses.
