TEGRETAL 100

About

Carbamazepine, marketed under brand names like Tegritol and Tegretal, is an anticonvulsant and mood-stabilizing medication primarily used in the treatment of epilepsy, trigeminal neuralgia, and bipolar disorder. Its mechanism of action involves stabilizing hyperexcited nerve membranes, inhibiting repetitive neuronal firing, and reducing the synaptic propagation of excitatory impulses. This is achieved by blocking voltage-gated sodium channels, thereby preventing the rapid influx of sodium ions into neurons that is characteristic of seizure activity.

Beyond its antiepileptic properties, carbamazepine is effective in managing the severe, paroxysmal pain associated with trigeminal neuralgia by reducing abnormal nerve impulses. In bipolar disorder, it acts as a mood stabilizer, helping to prevent extreme mood swings. Due to its complex pharmacokinetics and potential for drug interactions, careful dosage titration and therapeutic drug monitoring are often required to optimize efficacy and minimize adverse effects.
