Gabapentin hydrochloride is a potent, orally active P/Q type Ca2+ channel blocker. Gabapentin hydrochloride inhibits neuronal Ca2+ influx and reduction of neurotransmitter release. Gabapentin hydrochloride is a GABA analog that can be used to relieve neuropathic pain[1][2][3].
Gabapentin (0-300 μM) hydrochloride produces a concentration-dependent inhibition of the K+-induced [Ca2+]i increase in synaptosomes (IC50=14 μM; maximal inhibition by 36%)[1].
Gabapentin (100  μM) hydrochloride decreases the K+-evoked release of endogenous aspartate and glutamate in neocortical slices by 16 and 18%, respectively[1].
Gabapentin (0-1000 μM) hydrochloride reduces the K+-evoked [3H]-noradrenaline release in neocortical slices (IC50=48 μM; maximal inhibition of 46%) but not from synaptosomes[1].
Gabapentin (5 and 10 mg/kg; i.p.; once; male BALB/c mice) hydrochloride has improving effects on spatial and emotional cognitive performance of naive mice in Morris water maze (MWM), passive avoidance (PA) and modified elevated plus maze (mEPM) tasks[2].
Gabapentin (1-100 mg/kg; i.p.; once; male mice) hydrochloride has analgesic effect and reduces writhing in a dose-dependent manner[3].
