5. Study Description

Brief Summary
The use of zein nanoparticles as vehicles for drug delivery is under study, but of the effects observed in empty nanoparticles, in laboratory animals, the reduction of glucose levels was something worth studying. Thus, the present research on patients with prediabetes has been proposed. The objective is to assess the efficacy of zein nanoparticles on the glycemic control. For this purpose, a randomized, double blind crossover study has been designed. Target sample size is 60.
