Abstract: Objective To study the stability of tinidazole and spironolactone cream. Methods The content of tinidazole and spironolactone in cream were determined simultaneously by HPLC, and the period of validity of tinidazole spironolactone cream was predicted by accelerated test and long term test predictive validity. Results The content of tinidazole and spironolactone were decreasing gradually with the increasing of prolonging of time. After accelerated test, 6 months of tinidazole dropped 4.37%.spironolactone dropped 3.10%.After long term test, 12 months of tinidazole dropped 5.27%, spironolactone dropped 3.73%.Content and other indicators were in line with the provision. Conclusion The validity period of tinidazole and spironolactone was 12 months.
