Several calcium-channel modulators have been tried; for instance, pregabalin (Lyrica®) (anticonvulsant)  and oxacarbazepine (Trileptal®) (anticonvulsant) [2-4]. Calcium-channel modulators inhibit the activation of neuronal calcium channels and thereby inhibit the release of substances, such as excitatory amino acids, that are necessary for central sensitisation. These drugs are used to treat neuropathic pain . Several of these substances have a broad range of pharmacological actions and other mechanisms beyond calcium-channel modulation that might contribute to their effectiveness in treating neuropathic pain .
