Gabapentin 600 mg tablet is an anticonvulsant medication used for the treatment of epilepsy and neuropathic pain.Each film coated Gabapentin 600 mg tablet contains Gabapentin 600 mg and Excipients . Gabapentin binds with high affinity to the alpha-2-delta-1 subunit of voltage-gated Ca channels and appears to inhibit the action of alpha2delta subunits, thus decreasing the density of presynaptic voltage-gated calcium channels and subsequent release of excitatory neurotransmitters. This mechanism is likely to relieve neuropathic pain and is also responsible for the anti-epileptic action of gabapentin.
