Stability and sterility testing and dating taylor lautner and selena gomez are they dating
Testing procedures must include a stability indicating test which will distinguish the active ingredient from any degradation products and be able to make a reliable estimate of the quantity of any degradate.
The stability indicating test does not have to be the assay method used to determine product strength.
Since a dosage form is a complex unit and there are continued variables in the production process, such as change in personnel, raw material lots and suppliers, and equipment, it is imperative that stability studies are not limited only to initial production batches but a portion of annual production batches be the subject of an ongoing stability program.
When accelerated stability studies are performed, one batch may be adequate in order to establish a tentative expiration date.
There must be separate stability studies to support each expiration date.

Manufacturers, who contract with analytical laboratories to perform either end product testing or stability studies, or who produce product under contract for other firms are ultimately responsible for the quality of the product and must have copies of all analytical procedures employed and the appropriate documentation to assure their validity on file.
Likewise, repackers who rely on stability studies performed by the manufacturer must have copies of all analytical data necessary to support the expiration dating period.
It is commonly recommended that stability testing be performed initially, than every three months for the first year, then every six months for the second year, and then annually thereafter.The requirement that stability testing be performed in the same container-closure system as that in which the drug product is marketed has been subject to interpretation. Although stability studies were performed on the dosage unit in the original manufacturer’s container, the event of placing the dosage unit into a different storage unit may and often does affect the product’s shelf life.It is the policy of the Center for Drugs and Biologics to allow repacking into container-closure systems that can be demonstrated to be at least as protective or more protective than the original system without performing new stability studies prior to marketing.The USP defines controlled room temperature as being between 15 and 30 C (59 and 86 F).A product stored for stability at or near 15 C may have quite a different quality profile at its expiration date than a product stored at or near 30 C.
