Abstract

Diabetes Mellitus (DM) is a global epidemic, which represents a serious challenge for the public health system. One of the measures to maintain the normal glycemic level and reduce morbidity and mortality due to DM is the use of antidiabetic medicines such as glibenclamide (GLB) and gliclazide (GLZ). This work aimed at the development of unpublished, simple, fast, reliable and low cost analytical methods for the spectrophotometric determination of GLB and GLZ content in pharmaceutical formulations. Qualitative tests were performed from GLB and GLZ with Eosin (EOS). The formation of optically stable colored compounds with maximum absorption at 545 and 543 nm, respectively, was observed. Under optimized experimental conditions, analytical curves were obtained by relating the GLB and GLZ concentrations to the equivalent absorbances against the corresponding reagent blank. The proposed methods are based on the formation of binary, colored and highly stable complexes between investigated drugs and EOS. When
applied to the GLB and GLZ assay contained in commercial samples, the results showed that there were no significant differences between the proposed methods and the official methods. The accomplishment of this work was of paramount importance, since it allowed the development of unpublished, precise, accurate, reliable, simpler, faster, more versatile
analytical methods with greater economic feasibility (low cost). These methods can be used in routine analyzes for the quality control of antidiabetic drugs (GLB and GLZ) present in medicines consumed in Brazil.
