Oxiracetam (developmental code name ISF 2522) is a nootropic drug of the racetam family and a very mild stimulant.[1][2] Several studies suggest that the substance is safe even when high doses are consumed for a long period of time.[3][4][5] However, the mechanism of action of the racetam drug family is still a matter of research. Oxiracetam is not approved by Food and Drug Administration for any medical use in the United States.
