Xcopri mechanism of action?

How does Xcopri (cenobamate) work?

Xcopri’s mechanism of action centers on how it changes neuronal firing. Cenobamate acts on brain sodium channels and GABA-related signaling, which helps reduce abnormal electrical activity in the brain associated with focal seizures [1].

What does Xcopri do to sodium channels?

Cenobamate modulates voltage-gated sodium channels, which can make neurons less likely to fire repeatedly at high frequency. This “stabilizes” neuronal electrical activity and supports seizure control [1].

How does Xcopri affect GABA (inhibitory signaling)?

Xcopri also enhances inhibitory neurotransmission linked to GABA activity, shifting the balance away from excessive excitation. That additional inhibitory effect contributes to its overall anti-seizure activity [1].

Why does this matter for seizures?

Focal seizures involve disrupted signaling networks. By both dampening excitatory firing (via sodium-channel modulation) and increasing inhibitory effects (GABA-related action), cenobamate can lower the likelihood that seizure activity will spread or sustain [1].

What seizures is Xcopri indicated for (context)?

Xcopri is used for treating focal seizures (with or without secondary generalization) in adults [1].
