Epitab XR (400mg) 20 Tablets

Carbamazepine 400mg Tablet primarily exerts its therapeutic effects through its ability to stabilize neuronal membranes and inhibit voltage-gated sodium channels. By blocking these sodium channels, carbamazepine limits the repetitive firing of neurons, thereby reducing the propagation of abnormal nerve impulses. This mechanism is particularly relevant in conditions characterized by excessive neuronal excitability, such as epilepsy and certain types of neuropathic pain. Additionally, carbamazepine is believed to modulate neurotransmitter activity, including enhancing GABA (gamma-aminobutyric acid) and inhibiting glutamate release, which further contributes to its anticonvulsant and mood-stabilizing properties. The drug's anticonvulsant action is primarily associated with its major active metabolite, carbamazepine-10,11-epoxide, which also plays a role in its therapeutic effects.
