An accurate voltammetric method for the piroxicam determination at solid state, with a detection limit of 0.47 mg/g, is described. The method is based on the incorporation and oxidation of piroxicam within a carbon paste matrix bound with a nonconducting solvent. The method was successfully applied to the analysis of several pharmaceutical formulations.
