MEDICAL INFORMATION
Opicapone Key Facts
What dosages is Opicapone available in?
Opicapone is available as 25 mg and 50 mg oral capsules.
What is Opicapone used for?
Opicapone is a COMT inhibitor and is used to add-on treatment for people with Parkinson’s disease taking carbidopa/levodopa medications (e.g., Sinemet, Rytary) who experience “wearing-off” episodes.
How does Opicapone work?
Opicapone is a catechol-O-methyltransferase (COMT) inhibitor. COMT is a protein in your body that breaks down a commonly used Parkinson’s medication called levodopa. This causes levodopa to be less effective at relieving symptoms of Parkinson’s disease, which occur due to low dopamine levels in the brain. By blocking COMT, Opicapone allows levodopa to reach and stay at higher levels in the body. This means more levodopa can be converted into dopamine in the brain to relieve PD symptoms.
How do I take Opicapone?
The typical dose is 50 mg by mouth once per day at bedtime. For people with moderate liver problems, the typical dose is 25 mg by mouth once per day.
Is it safe for me to take Opicapone?

Effects of other drugs, drug classes and over-the-counter products on Opicapone
The following medications may interact with Opicapone:
- Non-Selective Monoamine Oxidase (MAO) Inhibitors: Both Opicapone and non-selective MAO inhibitors (e.g., phenelzine, isocarboxazid, and tranylcypromine) inhibit catecholamine metabolism, leading to increased levels of catecholamines. Concomitant use may increase the risk of possible arrhythmias, increased heart rate, and excessive changes in blood pressure
- Concomitant use of Opicapone with non-selective MAO inhibitors is contraindicated. Selective MAO-B inhibitors can be used concomitantly with Opicapone
- Drugs Metabolized by Catechol-O-Methyltransferase (COMT): Concomitant use of Opicapone with drugs metabolized by COMT may affect the pharmacokinetics of those drugs, which may increase the risk of possible arrhythmias, increased heart rate, and excessive changes in blood pressure. Drugs known to be metabolized by COMT should be administered with caution. Monitor for changes in heart rate, rhythm, and blood pressure in patients
- concomitantly treated with Opicapone and drugs metabolized by COMT.
