Lamez OD 150 Tablet SR contains Lamotrigine 150 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 and aspartate. This mechanism helps in controlling seizures and mood swings. Lamez OD 150 Tablet SR is a sustained-release formulation designed to provide a consistent plasma concentration, enhancing therapeutic efficacy and improving patient compliance by reducing dosing frequency. It is indicated for the treatment of partial seizures, generalized tonic-clonic seizures, and seizures associated with Lennox-Gastaut syndrome. Additionally, it is employed as a maintenance treatment for bipolar disorder to delay the occurrence of mood episodes. The medication should be initiated at a low dose with gradual titration to minimize the risk of serious skin reactions, including Stevens-Johnson syndrome. Caution is advised in patients with a history of hypersensitivity to Lamotrigine or related compounds. Common adverse effects include dizziness, headache, blurred vision, and nausea. Lamez OD 150 Tablet SR should be used under medical supervision with regular monitoring to ensure safety and efficacy.
