Abstract

The aim of this work was to develop and validate a dissolution test for diacerhein in capsules using spectrophotometric method. The dissolution established conditions were: 900 mL of sodium phosphate buffer pH 7.0 with 0.75 % of sodium lauryl sulphate as dissolution medium, using a basket apparatus at a stirring rate of 50 rpm. The drug release was evaluated by UV spectrophotometric method at 258 nm. The method was validated to meet requirements for a global regulatory filing. The validation included specificity, linearity, precision and accuracy. In addition, filter suitability and drug stability in medium were demonstrated. The comparison of the obtained dissolution profiles of capsules, obtained from three different brands (denominate product A, B and C) of 50 mg diacerhein, was performed and the results showed no significative difference among the products.
