Used primarily to treat neuropathic pain and epilepsy, this compound functions as an anticonvulsant and analgesic. It is commonly prescribed for conditions such as postherpetic neuralgia and diabetic neuropathy. It also finds use in managing certain types of seizures in epilepsy patients, often as an add-on therapy. Off-label, it is sometimes used for anxiety disorders, insomnia, and restless legs syndrome. Its mechanism involves modulating calcium channels in the central nervous system, reducing the release of excitatory neurotransmitters. Due to its impact on nerve signaling, it helps decrease abnormal electrical activity and pain signaling in the brain and spinal cord.
