| Abstract: | OBJECTIVE The stability of metamizole sodium, as a solid state model, was investigated by stepped humidity and temperature controlled method. METHODS The stability of drugs which were unstable to both heat and moisture could be studied by a single pair of experiments, one with stepped humidity control and one with stepped temperature control, rather than many standard isothermal studies, each at constant relative humidity. RESULTS The stepped humidity and temperature controlling system used in our experiment was only a normal environmental chamber. CONCLUSION The results indicates that the kinetic parameters obtained are comparable to those from isothermal studies. |
