Lamotrigine is an anti-convulsant drug that is used to treat epilepsy and the resulting seizures. As a treatment for epilepsy, lamotrigine can be prescribed to children as young as 2 years. The drug may also be used in the treatment of bipolar disorder as a tool to stabilize mood episodes. In this course of treatment, it is prescribed only to adults. Lamotrigine is a triazine derivate that inhibits voltage-sensitive sodium channels. Lamotrigine is an anticonvulsant drug used for treating epilepsy and bipolar disorder. It is used as an adjunct in treating clinical depression off-label. For epilepsy, Lamotrigine is used in the treatment of primary and secondary tonic-clonic seizures, focal seizures, and seizures associated with Lennox-Gastaut syndrome. Lamotrigine is used to prevent extreme mood swings of bipolar disorder in adults. Lamotrigine is known as an antiepileptic drug or anticonvulsant. Lamotrigine works by restoring the balance of certain natural substances found in the brain. Lamotrigine also blocks P-type and L-, N-, calcium channels and has weak 5-hydroxytryptamine-3 receptor inhibition. These actions inhibit release of glutamate at cortical projections in the ventral striatum limbic areas, and its anti-glutamatergic and neuroprotective effects have been pointed out as promising contributors to its mood stabilizing activity.
