Analysis of Scyllo-Inositol in a Wistar Rat Animal Model-A Preliminary Study

Background: Scyllo-inositol (SCI) is a naturally occurring carbocyclic sugar implicated in many biological processes. Studies have highlighted the potential of using SCI in Alzheimer's therapy. However, in order to fully use this compound in the treatment of neurovegetative diseases, its pharmacokinetics must be thoroughly understood. Objectives: We undertook the task of analyzing SCI in a Wistar rat animal model. The aim of this study was to observe the changes in SCI concentration after oral administration. Methods: All rats received 10 mg/kg of SCI as a solution in distilled water by oral gavage. Estimated parameters were based on the serum concentration of SCI observed in six individual rats with regard to time. Results: The first peak concentration appeared at 30 min for SCI. Thereafter, the serum SCI concentration increased rapidly and reached its highest level after approximately 1.5 h. There was no second peak in SCI concentration. The elimination half-life was determined to be 10.07 h and the mean residence time was 14.52 h. There were no side effects of SCI supplementation noticed during the study. Conclusions: Although our results present an analysis of SCI immediately after oral administration up to 48 h, further studies are necessary.
