Abstract:
Objective:To compare the similarity of dissolution curves of domestic ibuprofen suspension and the imported prepara-tion to provide the basis for the comprehensive quality evaluation of ibuprofen suspension. Methods: The in vitro dissolution of the products from four different manufacturers was investigated in pH 7. 2 phosphate buffer solution. The similarity of dissolution behavior was compared with that of the imported preparation in pH 1. 2 hydrochloric acid solution, pH 4. 5 acetate buffer solution, pH 6. 8 phos-phate buffer solution, pH 7. 2 phosphate buffer solution and water, respectively. Results:The dissolution rate of ibuprofen suspension from the four different manufacturers reached above 80% in 60 min. The dissolution profiles of ibuprofen suspension from two different manufacturers were similar with that of the imported preparation. Conclusion: The dissolution behavior of ibuprofen suspension from different manufacturers is significantly different.
