Des 4-trans-hydroxy-glibenclamide show hypoglycemic activity?

Abstract

Different doses of glibenclamide and of 4-transhydroxy-glibenclamide (main metabolite in man) were administered i.p. to rats and blood glucose was measured. The comparison of the doses capable of producing a 30% decrease of the glycemia shows that 4-trans-hydroxy-glibenclamide is about 6.5 times less potent than glibenclamide in our experimental conditions.
