Anticonvulsants may be used to alleviate painful dysesthesias, which frequently accompany peripheral neuropathies. Although they have many different mechanisms of action, their use for alleviating neuropathic pain probably depends on their general tendency to reduce neuronal excitability.

Gabapentin (Gralise, Neurontin)

Gabapentin is a membrane stabilizer, a structural analogue of the inhibitory neurotransmitter gamma-amino butyric acid (GABA), which paradoxically is thought not to exert an effect on GABA receptors. Gabapentin appears to exert action via the alpha(2)delta1 and alpha(2)delta2 auxiliary subunits of voltage-gaited calcium channels

It is used to manage pain and provide sedation in neuropathic pain.

Carbamazepine (Carbatrol, Equetro, Epitol, Tegretol, Tegretol-XR)

Carbamazepine is a sodium channel blocker that typically provides substantial or complete relief of pain in 80% of individuals with some forms of painful paresthesia. It reduces sustained, high-frequency, repetitive neural firing and is a potent enzyme inducer that can induce its own metabolism. Due to potentially serious blood dyscrasias, undertake benefit-to-risk evaluation before the drug is instituted.
