Antiepileptic, neuropathy

Properties

Gabapentin is an anti-epileptic drug of a new generation that increases the gamma-aminobutyric acid (GABA) levels, it is structurally related to the neurotransmitter GABA, by the addition of a cyclohexyl group to its backbone, but does not interact with GABAA or GABAB receptors of GABA uptake carriers of brain.
Gabapentin interacts with a high affinity-binding site in brain membranes, which is an auxiliary subunit of voltage-sensitive calcium ion channels. Gabapentin is not appreciably metabolized in the body and most of the dose is excreted unchanged in the urine. Peak plasma concentrations are usually achieved within 3 hours and elimination half-life is about 5 to 7 hours.
