In Vivo Antihyperglycemic Study of Insulin Self-Nanoemulsifying Drug Delivery System (SNEDDS)
Abstract
To deliver insulin orally requires an appropriate formulation strategy. Self nano-emulsifying drug delivery system (SNEDDS) can be used as an alternative to increase insulin bioavailability and activity. This study aim was to evaluate the antihyperglycemic activity of SNEDDS insulin. Insulin was loaded in SNEDDS by first dissolving it in glycerin. The dissolved content in glycerine was determined spectroscopically using the Bradford method. Insulin SNEDDS is then administered orally in rats in a variety of doses such as 43.39; 108,47; 216.94 IU / Kg. The rats used in this study were diabetic rats that had been induced with streptozotocin 48 mg / Kg BW. The insulin SNEDDS given can reduce blood glucose levels, while insulin without SNEDDS, PBS pH 7.4, and blank SNEDDS cannot lower blood glucose levels. The results of this study indicate that insulin given using the SNEDDS formulation can increase insulin activity, which is entirely ineffective if given orally without SNEDDS formulation.
