Neuroprotective and Antiamnestic Effects of a New Drug Emopag in Rats

Resumo

Emopag, a new drug, preventively administered in doses of 10 and 30 mg/kg/day over 4 days produced a pronounced neuroprotective effect in the model of brain ischemia caused by gravitational overload and reduced animal mortality from 17 to 0%. The preparation more effectively corrected neurological deficit than the reference drugs Mexidol (in considerably larger doses of 30 and 90 mg/kg/day) and antihypoxic drug amtizol (30 mg/kg/day). Moreover, Emopag exhibited considerable antiamnestic activity comparable to that of Mexidol (in 3-fold higher doses); in a dose of 30 mg/kg/day Emopag was more effective than Mexidol and amtizol in the same dose. Thus, Emopag showed marked neuroprotective and antiamnestic effects in the model of gravitational overload in rats.
