Effect of programmed humidification and temperature on drug stability

AimTo simplify the study on the effect of relative humidity and temperature on drug stability. MethodsThe stability of penicillin potassium as a model was studied with programmed humidifying and heating. ResultsResults of our programmed humidifying and heating experiments are comparable to those of traditional experiment at constant humidity and temperature. Conclusion Programmed humidifying and heating experiments are applicable to drug stability study.
