Gabapentin
Based on 14 publication(s) in Google Scholar
Gabapentin is a potent, orally active P/Q type Ca2+ channel blocker. Gabapentin inhibits neuronal Ca2+ influx and reduction of neurotransmitter release. Gabapentin is a GABA analog that can be used to relieve neuropathic pain.

Gabapentin (0-300 μM) 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) decreases the K+-evoked release of endogenous aspartate and glutamate in neocortical slices by 16 and 18%, respectively[1].
Gabapentin (0-1000 μM) reduces the K+-evoked [3H]-noradrenaline release in neocortical slices (IC50=48 μM; maximal inhibition of 46%) but not from synaptosomes[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Gabapentin (1-100 mg/kg; i.p.; once; male mice) has analgesic effect and reduces writhing in a dose-dependent manner[3].
