Description
Generic Name: entacapone
Drug Class: COMT inhibitors
Comtan Indications
Comtan is an oral prescription drug used to treat end-of-dose “wearing-off” among patients with Parkinson’s disease. This is usually given together with other medications, such as levodopa and carbidopa. Its effectiveness has not been established among people with Parkinson’s disease who do not experience end-of-dose “wearing-off”.
Comtan Dosage Forms
This is available in Comtan 200 mg tablets.
Comtan Mechanism of Action
This drug works by inhibiting catechol-O-methyltransferase or COMT while inhibiting the plasma pharmacokinetics of levodopa. When administered with carbidopa and levodopa, it stops the breakdown of the dopamine precursor and can help with its metabolism. This prevents the return or worsening of Parkinson’s symptoms.
How to Take Comtan
Before starting to take this Comtan, it is necessary to read the information leaflet or medication guide given by a healthcare professional. Before taking a medication, make sure you understand its purpose and directions. For further medical advice or additional details, contact your doctor or pharmacist.
This tablet is only meant to be taken by mouth and is usually prescribed up to 8 times a day together with each dose of levodopa or carbidopa. Take Comtan with or without a meal. Swallow the oral tablet and drink fluids right after.
Make a dosing schedule. Do not increase or decrease your Comtan dosage as it depends on the liver function, overall medical condition, and response to therapy.
