      • Procedure (Stability Conditions (Accelerated Condition and Long Term Condition),
      • Criteria for stability study of selection batch,
      • Stability Study Programme(Stability sample and testing time points for chemical analysis, Stability sample and testing time points for Microbiological analysis, Chemical stability test analysis and Microbiological stability test analysis) and
      • History log.
    • Stability station for ACC, Long term stability condition shall be as follows.

      • For: Accelerated condition : 0M, 3M, 6M
      • For: Long term stability condition: 0M, 3M, 6M, 9M, 12M, 18M, 24M, 36M, 48M, 60M up to the shelf life of the product and additional 12 months thereafter for the extension of expiration dating as per the requirement.
    • Tests required for the stability study shall be respective to the type of dosage form and shall be indicated as per the “stability study test guideline” (Annexure-3).
    • Test which has a “#” mark in the “stability analysis test guideline” shall apply for that dosage form and shall be selected for the test and for the evaluation parameters.
    • The sample quantity to be taken shall be decided base on the final product test procedure for each stability station and shall be taken 1.5 times excess for the evaluation purpose or as specified in the Stability Study protocol.
    • Protocol for Stability Study shall contain the “Stability analytical specification”, which gives information about the tests to be carried out and the evaluation parameter.
  • Stability Template Preparation in LIMS :

    • Stability Analytical Template shall be prepared by the LIMS Department and send to Section Head at the plant for checking and at the time of preparation mention all changes in the History log.
