is there any rules/ regulation that raw materials shelf life to be same as product shelf life?
Suppose Excipient shelf life is April 2024, and finished product shelf life is given April 2025. finished product is manufactured with that excipient. Is there any regulation that excipient should also have shelf life through out finished product.
Madam it is all about validation study which is to be performed during Pilot batch stability study but thumb rule is that Finished Product (FP) expiry is finalized based on expiry of active and excipients. Sort expiry active or excipients can not be used in FP if it is used then FP expiry must be same as expiry of active and excipients.

Therefore it is to be ensured that the formulation product’s shelf-life shall not exceed that of active raw materials used in that formulation.
