Diabetes is a metabolic disorder and is associated with serious complications caused by oxidative stress. The existing therapies only delay or reduce the severity of these complications but cannot completely prevent or reverse them. Antioxidant therapy is one promising alternative strategy to assuage these complications. However, the poor biopharmaceutical properties of many antioxidants limit their use as first line therapies. Here we propose a new therapeutic strategy to treat diabetes using biodegradable nano-co-encapsulated antioxidant particles (NanoCAPs) of ellagic acid (EA) and coenzyme Q(10) (CoQ(10)). The combination of EA and CoQ(10) showed beneficial effects in ameliorating lipid peroxidation, dyslipidemia and in preventing organ damage in streptozotocin induced diabetic rats. Significantly lower dose of EA and CoQ(10) in NanoCAPs showed equal and sometimes more prominent results in comparison to simple suspension suggesting improved efficacy Additionally, a statistically significant increase was observed in plasma insulin levels with nanoparticulate formulation of EA and CoQ(10) combination in comparison to simple suspension of EA, CoQ(10) alone or in combination as well as CoQ(10) nanoparticles. Collectively, this data indicates the potential use of NanoCAPs of EA and CoQ(10) in diabetes and reducing the associated complications.
