Oxiracetam

Social recognition ability of adult male rats pre-treated sufficiently long with Oxiracetam is resistant to the neurotoxicity effect of TMT. Oxiracetam administered at doses of 3, 10 and 30 mg/kg immediately after the acquisition session prevented the scopolamine induced prolongation of the transfer latency. Thus, oxiracetam forestalled the impairment of retrieval of memory trace: the animals were able to remember the spatial configuration of the plus-maze. On the contrary, oxiracetam was not effective in the diazepam treated mice. We suggest that beneficial effect of oxiracetam might be confounded or blocked by the anxiolytic effect of diazepam. Oxiracetam interacted with the glutamatergic NMDA receptor system and forestalled the impairment of retrieval of long-term memory. The results also justify the usage of the elevated plus-maze method in the evaluation of potential anti-amnesic or nootropic drugs. Several studies suggest that the substance is safe even when high doses are consumed for a long period of time.
