Pharmacological action
Gabagamma – antiepileptic drug. Gabapentin is similar in structure to the neurotransmitter gamma-aminobutyric acid (GABA), however, its mechanism of action is different from other drugs that interact with GABA receptors (valproate, barbiturates, benzodiazepines, GABA transaminase inhibitors, GABA uptake inhibitors, and GABA agonists GABA formulations ) It does not have GABA-ergic properties and does not affect the uptake and metabolism of GABA.
Preliminary studies have shown that gabapentin binds to the 2 – subunit of voltage-dependent calcium channels and reduces the flow of calcium ions, which plays an important role in the occurrence of neuropathic pain. Other mechanisms of action of gabapentin in neuropathic pain are a decrease in glutamate-dependent death of neurons, an increase in GABA synthesis, and suppression of the release of neurotransmitters of the monoamine group. Clinically significant concentrations of gabapentin do not bind to receptors of other common drugs or neurotransmitters, including GABAA, GABAB, benzodiazepine, glutamate and glycine NMDA receptors.
Unlike phenytoin and carbamazepine, gabapentin does not interact with sodium channels in vitro. Gabapentin partially attenuated the effects of the glutamate NMDA receptor agonist in some in vitro tests, but only at a concentration of more than 100 μmol, which is not achieved in vivo. Gabapentin slightly reduces the in vitro release of monoamine neurotransmitters.
