Nootropics are drugs, which ameliorate the functional “plasticity” of the central nervous system. The nootropic drug acts at the telencephalic level through a series of bioenergetic, hemorheological, microcirculatory and neurochemical mechanisms. As to this, recent data show a facilitation by piracetam, of the efficiency of the central cholinergic system.
