title: [Effect of programmed humidification and temperature on drug stability].
abstract: OBJECTIVE
  To simplify the study on the effect of relative humidity and temperature on drug stability.
  
  
  METHODS
  The stability of penicillin potassium as a model was studied with programmed humidifying and heating.
  
  
  RESULTS
  Results of our programmed humidifying and heating experiments are comparable to those of traditional experiment at constant humidity and temperature.
  
  
  CONCLUSIONS
  Programmed humidifying and heating experiments are applicable to drug stability study.
