Gabapentin is an anticonvulsant medication used in the management of peripheral neuropathic pains, postherpetic neuralgia, and partial-onset seizures.
It was originally developed as a novel anti-epileptic for the treatment of certain types of seizures – today it is also widely used to treat neuropathic pain.
Gabapentin has some stark advantages as compared with other anti-epileptics, such as a relatively benign adverse effect profile, wide therapeutic index, and lack of appreciable metabolism making it unlikely to participate in pharmacokinetic drug interactions.
