The study examined the effects of a novel neurotropic medication based on a lithium complex composed of lithium citrate, polymethylsiloxane, and aluminum oxide on electrophysiological parameters of the rat brain. In contrast to lithium carbonate (the reference drug), the novel preparation resulted in a wave-like dynamics of electrical activity in the visual cortex. Rhythmic photic stimulation of the rats treated with lithium carbonate resulted in appearance of the signs attesting to up-regulation of excitability of cerebral cortex in all examined ranges. In contrast, the complex lithium preparation diminished the delta power spectrum, which was the only affected frequency band. It is hypothesized that the complex lithium medication induces milder activation of the cerebral cortex in comparison with lithium carbonate. The novel medication composed of lithium citrate, aluminum oxide, and polymethylsiloxane, is characterized by greater efficacy and safety than the preparation based on inorganic lithium salt (lithium carbonate).
