Effective influence of the drug Cerebral and its micro- and macrofractions on the mean lifespan and degenerative process dynamics of Drosophila melanogaster have been investigated. No dose--effect dependence was detected when different concentrations of Cerebral were used. The administration of Cerebral as a neuroactivating remedy combined with piracetam and verapamil was most effective, leading to an increase in the lifespan and a delay in the appearance of brain degenerative processes.
