ONGENTYS Uses, Side Effects, Interactions, Warnings & Dosing

What is ONGENTYS?

What is ONGENTYS?

ONGENTYS is the brand name for opicapone oral capsules.

What dosages is ONGENTYS available in?

What dosages is ONGENTYS available in?

ONGENTYS is available as 25 mg and 50 mg oral capsules.

What is ONGENTYS used for?

What is ONGENTYS used for?

ONGENTYS 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 ONGENTYS work?

How does ONGENTYS work?

ONGENTYS 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, ONGENTYS 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 ONGENTYS?

Effects of other drugs, drug classes and over-the-counter products on ONGENTYS

Effects of other drugs, drug classes and over-the-counter products on ONGENTYS

The following medications may interact with ONGENTYS:

  • Non-Selective Monoamine Oxidase (MAO) Inhibitors: Both ONGENTYS 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 ONGENTYS with non-selective MAO inhibitors is contraindicated. Selective MAO-B inhibitors can be used concomitantly with ONGENTYS
  • Drugs Metabolized by Catechol-O-Methyltransferase (COMT): Concomitant use of ONGENTYS 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 ONGENTYS and drugs metabolized by COMT.
