In this study, a new size exclusion chromatographic method has been developed and validated for the analysis of mucopolysaccharide polysulfate used as an anti-inflammatory and antithrombotic agent in topical formulations. Mucopolysaccharide polysulfate was analyzed in Repromer OH-4000 (10 mu m, 8.0 x 300 mm) and Repromer OH-5000 (10 mu m, 8.0 x 300 mm) columns using a 0.05 M sodium sulfate isocratic elution mobile phase system at 40 degrees C with a flow rate of 1 mL min(-1) and detected by using refractive index detection. The method was validated by means of the limit of quantification, limit of detection, linearity, robustness, recovery, precision and accuracy using the Bioanalytical Method Validation Guidance. The calibration curve showed linearity in the 0.090-1.575 mg mL(-1) range. The limits of detection and quantification were found to be 45.000 and 90.000 mu g mL(-1), respectively. Assay recovery and precision of mucopolysaccharide polysulfate from topical formulations at 0.450, 0.900 and 1.350 mg mL(-1) concentrations were evaluated. Intra-day and inter-day relative standard deviation values were calculated to be less than 2.46%. The mean recovery was calculated as 96.64%. The validated method was successfully applied to the determination of mucopolysaccharide polysulfate in cream and gel formulations.
