Stabilitytest type:
Challenge test: in particularto sterility testing (microbiology test additional), should be carried out atleast at the beginning and at the end of the shelf-life, and the endotoxin testshould be conducted at the release testing
Photostability testing.
In-use sability, shouldbe performed on the rec**tituted or diluted drug product at the initial and finaltime points and intermediate time point if applicable on no less than 2 pilotbatches, At least one of these batches should be chosen towards the end of itsshelf life.
Position/ Orientation study: Forglass ampoule not required, Lyophilised powders/cakes still required as thereis still very slight chance of contact with closure
Accelerate stability expectation condition:Wherean expectation (based on development experience) exists that results fromaccelerated studies are likely to approach significant change criteria,increased testing should be conducted either by adding samples at the finaltime point or by including a fourth time point in the study design.
