[Comparative studies of antihypoxic, neuroprotective and analgesic action of succinate-containing drugs].

Abstract

Experiments with mice showed that, unlike reamberin (100 mg/kg), mexidol (100 mg/kg) and cytoflavin (1 ml/kg) act as antihypoxants in pressure and hermetic chambers but not in case of acute hemic and histotoxic hypoxia. Amtisol succinate (100 mg/kg), a reference antihypoxant, excels the other tried succinate-containing drugs in all models of acute hypoxia except the hermetic chamber. In addition, the neuroprotective action of mexidol (100 mg/kg/d) and cytoflavin (100 ml/kg/d) in rats with induced ischemic stroke which was stronger than that of reamberin and amtisol succinate (100 mg/kg/d). Besides, mexidol (100 mg/kg) but not cytoflavin (1 ml/kg), reamberin or amtisol succinate (100 mg/kg) had a distinct analgesic effect in rabbits. On the neuronal level, mexidol interacts with the GABAA- benzodiazepine-receptor complex in nearly 60% cells and inhibits ion currents through the NMDA-receptor ion channels in nearly 80% neurons.
