Revolutionizing hyperlipidemia treatment: Nanoencapsulated CoQ10 and selenium combat simvastatin-induced myopathy and insulin resistance in rats

Abstract

Purpose: The objective of this study was to develop a nanoencapsulated platform for coenzyme Q10 nanoparticles (coQNPs) or selenium nanoparticles (SeNPs) and explore their potential therapeutic benefits in treating hyperlipidemia and combating simvastatin (SV)-induced myopathy and adverse reactions in hyperlipidemic rats. Methods: The physical and chemical properties of the solid nanoparticles, coQNPs, and SeNPs were characterized, including zeta potential studies. Male Wistar albino rats were treated with various interventions for 112 days, including a nano-vehicle only, high-fat diet (HFD), HFD with SV alone, or with coQNPs or/and SeNPs for the last 30 days. Results: The coQNPs and SeNPs exhibited uniform spherical shapes with high encapsulation efficiency (EE% 91.20±2.14 and 94.89±1.54, respectively). The results demonstrated that coQNPs and SeNPs effectively reduced hyperlipidemia, insulin resistance, SV-induced myopathy, and hepatotoxicity. However, combining SV with coQNPs and SeNPs resulted in severe liver and muscle damage. Treatment with SV and SeNPs or SV and coQNPs alone showed significant improvements compared to SV treatment alone. Conclusion: These findings suggest that the CoQNPs or SeNPs platforms offer advanced relief for hyperlipidemia and insulin resistance while limiting adverse effects such as myopathy and hepatotoxicity.
