Lamez OD 100 Tablet SR contains Lamotrigine 100 mg, an antiepileptic medication primarily used for the management of epilepsy and bipolar disorder. Lamotrigine acts by stabilizing neuronal membranes and modulating voltage-sensitive sodium channels, thereby inhibiting the release of excitatory neurotransmitters such as glutamate. This mechanism helps in reducing the frequency and severity of seizures in patients with partial and generalized seizures, including tonic-clonic and absence seizures. Additionally, Lamotrigine is effective in the maintenance treatment of bipolar disorder by delaying the occurrence of mood episodes, particularly depressive episodes. The sustained-release formulation of Lamez OD 100 allows for a gradual release of the active ingredient, ensuring stable plasma concentrations, improved tolerability, and enhanced patient compliance through once-daily dosing. It is important to initiate treatment with a low dose and titrate gradually to minimize the risk of serious skin reactions, including Stevens-Johnson syndrome. Lamez OD 100 should be used under strict medical supervision, with regular monitoring for adverse effects such as dizziness, headache, blurred vision, and gastrointestinal disturbances. Dose adjustments may be necessary in patients with hepatic or renal impairment. This medication is contraindicated in individuals with known hypersensitivity to Lamotrigine or any excipients.
