[Article in Russian]


The central neurotropic effects of 4-phenylpyracetam, a new phenyl analog of pyracetam, were studied and compared with the effects of pyracetam, morpholene and 4-phenylpyrrolidone. 4-Phenylpyracetam was found to activate the operant behavior more powerfully, to remove psychodepressant effects of diazepam, to inhibit post-rotational nystagmus, and to prevent the development of retrograde amnesia. Unlike pyracetam, 4-phenylpyracetam exhibits a specific anticonvulsant action. When given in high doses, the compound under study produces psychodepressant effects.
