New Drug treatment for partial-onset seizures!

The U.S. Food and Drug Administration approved XCOPRI (cenobamate tablets) to treat partial-onset seizures in adults.
A seizure is a usually short episode of abnormal electrical activity in the brain. Seizures can cause uncontrolled movements, abnormal thinking or behavior, and abnormal sensations. Movements can be violent, and changes in consciousness can occur. Seizures occur when clusters of nerve cells (neurons) in the brain undergo uncontrolled activation. A partial-onset seizure begins in a limited area of the brain.

W

hile the precise mechanism by which XCOPRI exerts its therapeutic effect is unknown, XCOPRI is believed 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.

XCOPRI should be initiated at 12.5 mg once-daily and titrated every two weeks; it will be available in six tablet strengths for once-daily dosing: 12.5 mg, 25 mg, 50 mg, 100 mg, 150 mg, and 200 mg. XCOPRI can be combined with other AEDs or used alone.

Long-term safety of XCOPRI has been evaluated in the ongoing open-label extensions of the randomized studies and the open-label safety study. Additional clinical trials are investigating XCOPRI in other seizure types.

IMPORTANT SAFETY INFORMATION AND INDICATION FOR XCOPRI® (cenobamate tablets) CX

INDICATION:
XCOPRI is a prescription medicine used to treat partial-onset seizures in adults 18 years of age and older.

It is not known if XCOPRI is safe and effective in children under 18 years of age.

DO NOT TAKE XCOPRI IF YOU:

  • Are allergic to cenobamate or any of the other ingredients in XCOPRI.

XCOPRI CAN CAUSE SERIOUS SIDE EFFECTS, INCLUDING:

Allergic reactions: XCOPRI can cause serious skin rash or other serious 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.

Take XCOPRI exactly as your healthcare provider tells you to take it. It is very important to increase your dose of XCOPRI slowly, as instructed by your healthcare provider.
