Chemical Structure

XCOPRI is a white to off-white crystalline powder. It is very soluble in aqueous solutions (water 1.7 mg/mL) and has higher solubility in organic solvents like ethanol (209.4 mg/mL).

Mechanism of Action

The precise mechanism by which cenobamate exerts its therapeutic effects in patients with partial-onset seizures is unknown. Cenobamate has been demonstrated to reduce repetitive neuronal firing by inhibiting voltage-gated sodium currents. It is also a positive allosteric modulator of the γ-aminobutyric acid (GABAA) ion channel.

What is the most important information I should know about Xcopri?

Xcopri can cause serious side effects, including:

Serious or life threatening allergic reactions which may affect organs and other parts of your body like the liver or blood cells. You may or may not have a rash with these types of reactions.
Call your healthcare provider right away and go to the nearest emergency room if you have any of the following:

  • swelling of your face, eyes, lips, or tongue
  • trouble swallowing or breathing
  • a skin rash
  • hives
  • fever, swollen glands, or sore throat that does not go away or comes and goes
  • painful sores in the mouth or around your eyes
  • yellowing of your skin or eyes
  • unusual bruising or bleeding
  • severe fatigue or weakness
  • severe muscle pain
  • frequent infections that do not go away

These symptoms may be the first signs of a serious reaction. A healthcare provider should examine you to decide if you should continue taking Xcopri.
