【Abstract】 Objective To develop a method for the preparation and quality control of compound ornidazole emulsion. Methods To sodium carboxymethyl cellulose (CMC Na) was added water for injection quantum satis. Sodium bisulfite was added after complete swelling of the CMC Na, followed by trituration for thorough mixing. Cod liver oil,Tween 80,ornidazole and ketoconazole were then successively added, followed by trituration for thorough mixing.By adding water and further trituration finally, the preparation of compound ornidazole emulsion was finished. The content of ornidazole in the suspension was determined with dual wavelength κ ratio spectrophotometry. Results The calibration curves were linear when the concentrations of ornidazole and ketoconazole were within the ranges of 7.04-14.08 μg·mL 1 , r =0.999 5 and 9.984- 19.968 μg·mL 1 , r =0.999 9 ( n =7), respectively. The average rates of recovery of ornidazole and ketoconazole were 100.10% ( RSD =0.58%, n =4) and 100.10%( RSD =0.90%, n =4), respectively. Conclusion Compound ornidazole emulsion was shown to be stable, handy in preparation and the method of its quality control was accurate.更多还原
