Oxiracetam (ISF 2522) is a nootropic drug of the racetam family and stimulant. Several animal studies suggest that the substance is safe even when high doses are consumed for a long period of time.[medical citation needed] However, the mechanism of action of the racetam drug family is still a matter of research. There has been effort put into investigating the possible use of oxiracetam as a medication to attenuate the symptoms of dementia. However, no convincing results were obtained from studies where patients suffering from Alzheimer's dementia or organic solvent abuse were given 800 mg of the drug orally twice daily. The proven effects of the drug are limited to beneficial effects that lead to higher scores in tests for logical performance, attention, concentration, memory and spatial orientation. According to V. Gallai et al, oxiracetam is more effective than piracetam for this purpose.
