[Federal Register Volume 62, Number 131 (Wednesday, July 9, 1997)] [Notices] [Pages 36836-36837] From the Federal Register Online via the Government Publishing Office [www.gpo.gov] [FR Doc No: 97-17796] ----------------------------------------------------------------------- DEPARTMENT OF HEALTH AND HUMAN SERVICES Food and Drug Administration [Docket No. 97D-0267] Guidance for Industry on Expiration Dating and Stability Testing of Solid Oral Dosage Form Drugs Containing Iron; Availability AGENCY: Food and Drug Administration, HHS. ACTION: Notice. ----------------------------------------------------------------------- SUMMARY: The Food and Drug Administration (FDA) is announcing the availability of a guidance document entitled ``Guidance for Industry: Expiration Dating and Stability Testing of Solid Oral Dosage Form Drugs Containing Iron.'' The guidance document provides information to manufacturers of iron-containing drug products who are affected by a final rule that requires label warning statements and unit-dose packaging for solid oral drug products that contain 30 milligrams (mg) or more of iron per dosage unit. The guidance document describes the circumstances under which the agency does not intend to object, for a limited period of time, to modified expiration dating by drug manufacturers and packagers who are required to package their products into unit-dose containers under the final rule. DATES: Written comments may be submitted at any time. The agency does not expect to be guided by the recommendations in this guidance document after July 15, 1999. ADDRESSES: Submit written requests for single copies of ``Guidance for Industry: Expiration Dating and Stability Testing of Solid Oral Dosage Form Drugs Containing Iron'' to the Drug Information Branch (HFD-210), Center for Drug Evaluation and Research, Food and Drug Administration, 5600 Fishers Lane, Rockville, MD 20857. Send one self-addressed adhesive label to assist that office in processing your requests. FOR FURTHER INFORMATION CONTACT: Barry Rothman, Center for Drug Evaluation and Research (HFD-325), Food and Drug Administration, 7520 Standish Pl., Rockville, MD 20855, 301-594-0098. SUPPLEMENTARY INFORMATION: FDA is announcing the availability of a guidance document entitled ``Guidance for Industry: Expiration Dating and Stability Testing of Solid Oral Dosage Form Drugs Containing Iron.'' The purpose of this guidance document is to describe an approach to stability testing and expiration dating for a limited class of iron-containing products for certain manufacturers and packagers of drug products containing iron. In the Federal Register of January 15, 1997 (62 FR 2218), FDA issued a final rule entitled ``Iron-Containing Supplements and Drugs: Label Warning Statements and Unit-Dose Packaging Requirements'' (hereinafter called the iron regulations). The iron regulations, effective July 15, 1997, require label warning statements and unit-dose packaging for solid oral drug products that contain 30 mg or more of iron per dosage unit. FDA requires that drug products bear an expiration date determined by appropriate stability testing Secs. 211.137 and 211.166 (21 CFR 211.137 and 211.166). Drug product stability needs to be evaluated over time in the same container-closure system that will be used in the marketing of the product, and accelerated stability studies can be used to support tentative expiration dates in the event that full shelf life studies are not available. When a firm changes the packaging of a drug product, stability testing must be performed on the product in its new packaging, and expiration dating must reflect the results of the new stability testing. To meet the requirements of the iron regulations, all manufacturers of solid oral drug products that contain 30 mg or more of iron per dosage unit must package their products in unit-dose packaging. As a result, these manufacturers must determine an appropriate expiration date for that packaging. Because the final iron regulations were published only 6 months before they were to take effect, accelerated stability testing may be necessary to justify an expiration date of more than 6 months. However, accelerated stability studies are impractical for some drug products containing iron, especially multivitamin products, because such products often do not perform well under the artificially stressful conditions of accelerated studies. For these drug products, real-time stability testing may be the only method to determine an appropriate expiration date. To minimize the burden faced by those manufacturers and packagers who have made good faith efforts to comply with the stability testing requirements but were unable to do so, FDA advises that, for a limited period of time, it does not intend to object if such a firm fails to comply with Secs. 211.137 and 211.166, so long as it establishes expiration dates and stability testing protocols under the specific approach described in the guidance document. FDA expects that sufficient stability testing will be performed in a timely fashion; therefore, the agency does not expect to be guided by the recommendations in this guidance document after July 15, 1999. This guidance document represents the agency's current thinking on expiration dating for solid oral drug products containing 30 mg or more of iron. 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 approach satisfies the requirement of the applicable statute, regulations, or both. Interested persons may, at any time, submit written comments on the guidance to the Dockets Management Branch (HFA-305), Food and Drug Administration, 12420 Parklawn Dr., rm. 1-23, Rockville, MD 20857. Two copies of any comments are to be submitted, except that individuals may submit one copy. Requests and comments are to be identified with the docket number found in brackets in the heading of this document. The guidance and received comments may be seen in the office above between 9 a.m. and 4 p.m., Monday through Friday. An electronic version of this guidance is also available on the Internet using the World Wide Web at http://www.fda.gov/cder/ guidance.htm. [[Page 36837]] Dated: June 30, 1997. William K.
