​Pharmacology - Gabapentin 
Effective anticonvulsant and analgesic.

Method of Operation 
The action is attributed to the binding of the alpha 2- sigma-1 and alpha 2- sigma-2 subunits of voltage-activated Ca2+ channels (P/Q or N-type) in order to prevent the entry of Ca2+ and the exocytosis of transmitter (glutamate) from nerve terminals.
It has also been suggested that there is an enhanced release of GABA.
