Hold study evaluation plays a main role for manufacturing the
new products in GMP conditions. Based on the hold time study
establishment and shelf life product manufacturing plan can be
decided. Hold time study results are passing the 60 days time interval
then 45 days limit is good for general practice. In the same way if the
stage is passing the 72 hours interval then 48 hours limit is general
practice. If not performed the hold study in the product development
stage then in commercial level need to perform the hold study for first
three commercial batches
