An anticonvulsant medication that stabilizes mood by blocking voltage-gated sodium channels in neurons, used to treat epilepsy and bipolar disorder. It helps prevent both manic and depressive episodes.
A synthetic compound name derived from its chemical structure, developed by GlaxoSmithKline in the 1980s. The '-ine' suffix is common in pharmaceutical nomenclature for nitrogen-containing compounds.

However, it can cause a potentially life-threatening skin rash called Stevens-Johnson syndrome, so patients must start with tiny doses and increase very slowly.
