Used primarily as an anticonvulsant medication, particularly in the treatment of epilepsy. It helps control various types of seizures, including generalized tonic-clonic, absence, and myoclonic seizures. The compound is also prescribed for managing bipolar disorder due to its mood-stabilizing properties. Additionally, it may be used in the prevention of migraine headaches. Its mechanism involves increasing the concentration of gamma-aminobutyric acid (GABA) in the brain, which helps reduce neuronal excitability.
