This site displays a prototype of a “Web 2.0” version of the daily Federal Register. It is not an official legal edition of the Federal Register, and does not replace the official print version or the official electronic version on GPO’s govinfo.gov.
The documents posted on this site are XML renditions of published Federal Register documents. Each document posted on the site includes a link to the corresponding official PDF file on govinfo.gov. This prototype edition of the daily Federal Register on FederalRegister.gov will remain an unofficial informational resource until the Administrative Committee of the Federal Register (ACFR) issues a regulation granting it official legal status. For complete information about, and access to, our official publications and services, go to About the Federal Register on NARA's archives.gov.
The OFR/GPO partnership is committed to presenting accurate and reliable regulatory information on FederalRegister.gov with the objective of establishing the XML-based Federal Register as an ACFR-sanctioned publication in the future. While every effort has been made to ensure that the material on FederalRegister.gov is accurately displayed, consistent with the official SGML-based PDF version on govinfo.gov, those relying on it for legal research should verify their results against an official edition of the Federal Register. Until the ACFR grants it official status, the XML rendition of the daily Federal Register on FederalRegister.gov does not provide legal notice to the public or judicial notice to the courts.
Food and Drug Administration, HHS.
The Food and Drug Administration (FDA) is announcing the availability of a guidance for industry entitled “ANDAs: Impurities in Drug Substances,” which is a revision of a guidance for industry of the same name that published in November 1999. The guidance provides recommendations for applicants on what chemistry, manufacturing, and controls (CMC) information to include regarding the reporting, identification, and qualification of impurities in drug substances produced by chemical synthesis when submitting original abbreviated new drug applications (ANDAs); drug master files (DMFs), including type II DMFs; and ANDA supplements for changes in the synthesis or processing of a drug substance.
Submit written or electronic comments on agency guidances at any time.
Submit written requests for single copies of the guidance to the Division of Drug Information (HFD-240), Center for Drug Evaluation and Research, Food and Drug Administration, 10903 New Hampshire Ave., Bldg. 51, rm. 2201, Silver Spring, MD 20993-0002.

FDA is announcing the availability of a revised guidance for industry entitled “ANDAs: Impurities in Drug Substances.” The guidance provides revised recommendations on what CMC information to include regarding the reporting, identification, and qualification of impurities in drug substances produced by chemical synthesis when submitting: (1) Original ANDAs; (2) DMFs, including type II DMFs; and (3) ANDA supplements for changes in the synthesis or processing of a drug substance. The guidance also provides recommendations for establishing acceptance criteria for impurities in drug substances.
In November 1999, FDA published the first version of this guidance. In 2003, the International Conference on Harmonisation made changes to recommendations on impurities in drug substances for new drug applications in the guidance for industry entitled “Q3A Impurities in New Drug Substances” (Revision 1) (Q3A(R)). As a result of these changes, FDA began an effort to revise this guidance for ANDAs. FDA has revised the guidance to update information on listing impurities, setting acceptance criteria, and qualifying impurities (thresholds and procedures) in ANDAs to make it consistent with Q3A(R).
On January 31, 2005 (70 FR 4857), FDA announced the availability of the draft revision for public comment. The comment period closed on May 2, 2005. A number of comments were received, which the agency considered carefully as it began the process of finalizing the guidance.
This guidance is being issued consistent with FDA's good guidance practices regulation (21 CFR 10.115). The guidance represents the agency's current thinking on impurities in drug substances for generic drugs. It does not create or confer any rights for or on any person and does not operate to bind FDA or the public. An alternative approach may be used if such an approach satisfies the requirements of the applicable statutes and regulations.
Interested persons may submit to the Division of Dockets Management (see ADDRESSES) written or electronic comments regarding this document. Submit a single copy of electronic comments or two paper copies of any mailed comments, except that individuals may submit one paper copy. Comments are to be identified with the docket number found in brackets in the heading of this document. Received comments may be seen in the Division of Dockets Management between 9 a.m. and 4 p.m., Monday through Friday.
III. Paperwork Reduction Act of 1995
This guidance refers to previously approved collections of information found in FDA regulations. These collections of information are subject to review by the Office of Management and Budget (OMB) under the Paperwork Reduction Act of 1995 (44 U.S.C. 3501-3520). The collections of information in 21 CFR part 314 have been approved under OMB Control No. 0910-0001.
