title: [Comparative characteristics of the nootropic action of fenibut and fepiron].
abstract: The nootropic effects of phenibut and phepyrone administered in low doses were studied and compared in experiments on rats. Experiments made in a water maze and a shuttle box demonstrated that both phepyrone and piracetam improved the learning performance in rats. In the doses tested phenibut did not produce any nootropic activity.
