Procedure: The procedure shall be as follows 5.1

Introduction 5.1.1 To provide guidance on how to conduct stability studies under various environmental conditions such as temperature and humidity in container closure system simulated to dispatch containers.

5.2

Selection of batches 5.2.1 Stability studies shall be conducted on at least three primary batches of the drug substance. The batches shall be manufactured to a minimum of pilot scale by the same synthetic route or commercially produced batches. 5.2.2 One commercial batch shall be added to the long term stability on every year [add on batch]. 5.2.3 Reprocessing or reworking batches shall be kept for stability studies. 5.2.4 Materials which undergo physical modification such as micronization should be kept for stability studies. 5.2.5 If the batch uses recovery solvents in the manufacturing process one batch should be kept for stability study inorder to evaluate their effect on stability of the drug substance. 5.2.6 Enter the details of batches selected in Stability Programme Register in format number - 01
