SUPPLEMENTARY INFORMATION:
I. Background
FDA is announcing the availability of a draft guidance for industry entitled “Drug Interactions Section of Labeling for Human Prescription Drug and Biological Products—Content and Format.” The draft guidance is intended to assist applicants in developing the DRUG INTERACTIONS section of the Prescribing Information labeling as described in FDA regulations for the content and format of labeling for human prescription drug and biological products.
21 CFR 201.56(a) and (d) and 201.57(c)(8). This guidance applies to drugs, including biological products that are regulated as drugs. For the purpose of this guidance, “drug product” or “drug” will be used to refer to human prescription drug and biological products that are regulated as drugs.
Prescription drug labeling must contain a summary of the essential information necessary for safe and effective use of the drug and is a primary tool for FDA to communicate drug interaction information to healthcare practitioners. Effective communication of drug interaction information informs the optimal use of the drug and the healthcare practitioner's clinical decision-making ( e.g., prescribing decisions or management instructions).
The purpose of this guidance is to provide recommendations on what information to include in, and how to present and organize the information within, the DRUG INTERACTIONS section of prescription drug labeling to enhance communication of clinically significant drug interactions and facilitate the safe and effective use of prescription drugs by healthcare practitioners. This guidance also provides illustrative examples of the content and format of drug interaction information in prescription drug labeling.
In addition, the guidance includes an FDA website ( https://www.fda.gov/CYPandTransporterInteractingDrugs ) as one resource that health care practitioners can use to view examples of clinical substrates, inhibitors, and inducers of Cytochrome P-450 (CYP) enzymes and substrates and inhibitors of transporters. FDA is seeking input regarding the utility of this website as a resource that health care practitioners can reference to find examples of clinical substrates, inhibitors, and inducers of CYP enzymes and substrates and inhibitors of transporters. FDA is also seeking input on ways to describe drug interactions in labeling, specifically when drugs have numerous, clinically relevant drug interactions ( e.g., azole antimycotics) that require listing many interactions. In addition, FDA is seeking input on ways to describe complex drug-interaction scenarios, including but not limited to:
- Concurrent inhibition of an enzyme and a transporter by a drug;
- Concurrent inhibition and induction of a drug's metabolic pathway by one or more enzymes;
- Increased inhibition of drug elimination by use of inhibitors of more than one enzyme that metabolizes the drug;
- Inhibition of an enzyme other than the genetic polymorphic enzyme in poor metabolizers taking a substrate metabolized by both enzymes;
- Effect of enzyme/transporter inhibitors in subjects with organ impairment; and
- Two drugs acting as both precipitant and object of a drug interaction.
The draft guidance, when finalized, will represent the current thinking of FDA on “Drug Interaction Information in Human Prescription Drug and Biological Product Labeling.” It does not establish any rights for any person and is not binding on FDA or the public. You can use an alternative approach if it satisfies the requirements of the applicable statutes and regulations.
II. Paperwork Reduction Act of 1995
While this guidance contains no collection of information, it does refer to previously approved FDA collections of information. The previously approved collections of information are subject to review by the Office of Management and Budget (OMB) under the Paperwork Reduction Act of 1995 (PRA) (44 U.S.C. 3501-3521). The collections of information in 21 CFR parts 314 and 601 are approved under OMB control numbers 0910-0001 and 0910-0338, respectively. The collections of information in 21 CFR parts 201.56 and 201.57 have been approved under OMB control number 0910-0572.
