Lamitor OD 200 Tablet SR contains Lamotrigine 200mg, an antiepileptic medication primarily indicated for the management of epilepsy and bipolar disorder. Lamotrigine acts by stabilizing neuronal membranes through inhibition of voltage-sensitive sodium channels, thereby reducing the release of excitatory neurotransmitters such as glutamate. This mechanism helps in controlling seizures and mood episodes. Lamitor OD 200 Tablet SR is a sustained-release formulation designed to provide a consistent plasma concentration, improving patient compliance by allowing once-daily dosing. It is effective in treating various types of seizures, including partial seizures, generalized tonic-clonic seizures, and seizures associated with Lennox-Gastaut syndrome. Additionally, Lamotrigine is utilized as a mood stabilizer in 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 such as Stevens-Johnson syndrome. Common side effects include dizziness, headache, blurred vision, and gastrointestinal disturbances. Lamitor OD 200 Tablet SR should be used under medical supervision with regular monitoring, especially during dose adjustments or when combined with other antiepileptic drugs. It is contraindicated in patients with known hypersensitivity to Lamotrigine or any excipients in the formulation.
