Xval-OD 1000 Tablet contains Divalproex 1000 mg, an anticonvulsant and mood-stabilizing agent primarily used in the management of epilepsy, bipolar disorder, and migraine prophylaxis. Divalproex is a compound of sodium valproate and valproic acid that increases gamma-aminobutyric acid (GABA) levels in the brain, thereby exerting an inhibitory effect on neuronal firing and stabilizing electrical activity. Xval-OD 1000 is indicated for the treatment of various seizure types, including absence, complex partial, and simple partial seizures. Additionally, it is effective in the acute treatment and prophylaxis of manic episodes associated with bipolar disorder and in reducing the frequency of migraine headaches. The extended-release formulation allows for once-daily dosing, improving patient compliance and maintaining steady plasma drug concentrations. Common side effects may include gastrointestinal disturbances, tremor, weight gain, and somnolence. Serious adverse effects such as hepatotoxicity, pancreatitis, and thrombocytopenia require regular monitoring of liver function tests, complete blood counts, and serum valproate levels. Use during pregnancy is contraindicated due to teratogenicity. Dose adjustments may be necessary in patients with hepatic impairment or concomitant use of other antiepileptic drugs. Xval-OD 1000 should be prescribed and monitored by healthcare professionals experienced in managing neurological and psychiatric disorders.
