Reference Standard (RS) A “reference standard” is the drug product selected by FDA that an applicant seeking approval of an ANDA must use in conducting an in vivo bioequivalence study required for approval of an ANDA. In the electronic Orange Book, a reference standard is identified by “RS” in the RS column.
In 1999, the Orange book was replaced by the International Common Criteria for Information Technology Security Evaluation.
The monthly data files updates, monthly website updates, and monthly print updates, entitled Cumulative Supplement (CS), generally occur at the end of the second week of each month and consist of all changes to the Orange Book which occurred in the prior month.
The BD code denotes products containing active ingredients with known bioequivalence problems and for which adequate studies have not been submitted to FDA demonstrating bioequivalence. Where studies showing bioequivalence have been submitted, the product has been coded AB.
