Section 512(b) of the Federal Food, Drug and Cosmetic Act (21 U.S.C. 360b) establishes the requirements for new animal drug approval.  21 CFR 514.1 specifies the proper form and the information required to be submitted. Included is a requirement under section 514.1(b)(5)(x) that an applicant submit data from stability studies completed as well as information about studies that are underway to substantiate the request for a specific expiration date and provide information on the stability of the drug products.

CGMP regulations under 21 CFR Part 200 also require stability testing for pharmaceutical dosage forms (21 CFR 211) and Type A Medicated Articles (medicated premixes) (21 CFR 226).  This guideline can be used as an aid to conduct the required stability testing.
