Lamez OD 50 Tablet SR contains Lamotrigine 50 mg, an antiepileptic medication primarily indicated for the treatment of epilepsy and bipolar disorder. Lamotrigine acts by stabilizing neuronal membranes through the inhibition of voltage-sensitive sodium channels, thereby modulating the release of excitatory neurotransmitters such as glutamate and aspartate. 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, particularly in delaying the occurrence of mood episodes, including depressive episodes. The sustained-release (SR) formulation ensures a controlled release of the active ingredient, promoting consistent plasma levels and improving patient compliance by allowing once-daily dosing. Lamez OD 50 should be administered under medical supervision, with careful dose titration to minimize the risk of serious adverse reactions such as Stevens-Johnson syndrome. Common side effects may include dizziness, headache, blurred vision, and gastrointestinal disturbances. It is contraindicated in patients with known hypersensitivity to Lamotrigine or any excipients. Caution is advised when used concomitantly with other antiepileptic drugs or in patients with hepatic or renal impairment.
