Revista Vita et Sanitas, Trindade, v. 5, n. 1, p. 2-12, jan./dez, 2011.e- 1982-5951http://repositorio.bc.ufg.br/handle/ri/15452Several methods, eg colorimetric and chromatographic methods have been used for the identification and quantification of methyldopa in pharmaceutical formulations, as well as in samples of clinical interest, which typically have high analysis time and reagent consumption. Thus, much effort has been directed towards the development of analytical procedures simple, fast, accurate and low cost. In this context, we intend to evaluate the electrochemical behavior of methyldopa with analytical purposes and chemical-pharmaceutical products, since redox mechanisms are probably involved in the process of decarboxylation and action of methyldopa in nervous tissue. The redox behavior of methyldopa was evaluated by cyclic voltammetry, varying different parameters (Scanning Range of Potential or Reversal Potential and Scan Rate), as well as characteristics of the supporting electrolyte (pH, Salt) and working electrode (Carbon Paste, Glassy Carbon and Pt).porAcesso AbertoMetildopaEletrólitosCaracterização eletroquímicaMethyldopaElectrolytesElectrochemical characterizationArtigo
