Objective: To develop acrylate based transdermal drug delivery system (TDDS) for glibenclamide and evaluate it for its pharmacodynamic performance in male Wistar rats.
Methods: The drug embedded in a polymeric matrix of polymethyl methacrylate and ethylcellulose was evaluated for its hypoglycemic activity in normal and streptozotocin induced diabetic rats in comparison with its oral therapy. A glucose tolerance test (GTT) was conducted in oral, TDDS and control group.
Results: TDDS significantly sustained the hypoglycemic activity for 24 hrs in normal rats when compared to oral administration where the effect declined after 8 hrs. In diabetic rats, normoglycemic levels were maintained for a period of 24 hrs after transdermal delivery, an effect comparable to that of oral glibenclamide. The GTT curve was inhibited in both the groups. However, the reduction was slow and sustained in case of TDDS when compared to oral administration where significant hypoglycemic response was observed in all the three studies performed.
Conclusion: The transdermal system is effective in preventing the frequent hypoglycemic episodes encountered after oral glibenclamide administration.
