The electrochemical behavior of anti-hyperglycemic (glibenclamide, GBC) was investigated and discussed at HMDE in Britton-Robinson universal buffer using cyclic voltammetry.Its voltammogram at pH values 6-11 displayed a quasi-reversible redox couple one-electron peak corresponding to a catalytic hydrogen process.Based on this voltammetric peak, a validated and sensitive SW-AdCS voltammetric method...
