Abstract:
The authors examined sodium concentrations from 97 oxcarbazepine-treated (OXC) and 451 carbamazepine-treated (CBZ) patients with epilepsy using cross-section and follow-up studies. The frequency of hyponatremia (Na+ < or = 134 mEq/L) was 29.9% among OXC-treated patients and 13.5% among CBZ-treated patients (p < 0.0001). Hyponatremia (Na+ < or = 128 mEq/L) was severe: 12.4% of OXC-treated patients and 2.8% of CBZ-treated patients (p < 0.001). Advanced age was a risk factor for hyponatremia. Hyponatremia, once present, persisted in both groups.

Antiepileptic Drugs: Calcium Channel Blockers
Calcium channel blockers exert their antiepileptic effects by targeting T-type calcium channels, which are integral to transmitting nerve signals in the central nervous system. These channels allow the passage of calcium ions, which are vital for neuronal communication. By inhibiting T-type calcium channels, calcium channel blockers effectively reduce the release of neurotransmitters and...
