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. Additionally, it is sometimes used off-label for conditions like restless legs syndrome, fibromyalgia, and certain anxiety disorders. Its mechanism involves modulating calcium channels in the central nervous system, reducing abnormal neuronal activity. Due to its favorable safety profile and low potential for drug interactions, it is widely used in elderly and multi-medicated patients.
