The objective was to study the materials in the fourth with temperature conditions (temperature and humidity control, etc.), evaluating its quality stability changes over time, and lead to the establishment of the medicinal materials at this temperature with check period and the recommended storage

The goal is studies this bulk drugs under the fourth temperature band condition (control temperature and humidity and so on) a stability, appraises its quality along with the time change, from this and establishes this bulk drugs in this temperature band re-check time and the recommendation storing
