SUPPLEMENTARY INFORMATION:

In 1984, Congress enacted the Drug Price Competition and Patent Term Restoration Act of 1984 (Pub. L. 98-417) (the 1984 amendments), which authorized the approval of duplicate versions of drug products under an ANDA procedure. ANDA applicants must, with certain exceptions, show that the drug for which they are seeking approval contains the same active ingredient in the same strength and dosage form as the “listed drug,” which is a version of the drug that was previously approved. ANDA applicants do not have to repeat the extensive clinical testing otherwise necessary to gain approval of a new drug application (NDA).

The 1984 amendments include what is now section 505(j)(7) of the Federal Food, Drug, and Cosmetic Act (21 U.S.C. 355(j)(7)), which requires FDA to publish a list of all approved drugs. FDA publishes this list as part of the “Approved Drug Products With Therapeutic Equivalence Evaluations,” which is known generally as the “Orange Book.” Under FDA regulations, drugs are removed from the list if the Agency withdraws or suspends approval of the drug's NDA or ANDA for reasons of safety or effectiveness or if FDA determines that the listed drug was withdrawn from sale for reasons of safety or effectiveness (21 CFR 314.162).

A person may petition the Agency to determine, or the Agency may determine on its own initiative, whether a listed drug was withdrawn from sale for reasons of safety or effectiveness. This determination may be made at any time after the drug has been withdrawn from sale, but must be made prior to approving an ANDA that refers to the listed drug (§ 314.161 (21 CFR 314.161)). FDA may not approve an ANDA that does not refer to a listed drug.

NIPRIDE RTU (sodium nitroprusside), 10 mg/50 mL (0.2 mg/mL), is the subject of NDA 209387, held by Exela Pharma Sciences, LLC, and initially approved on March 8, 2017. NIPRIDE RTU is indicated for immediate reduction of blood pressure of adult and pediatric patients in hypertensive crises; induction and maintenance of controlled hypotension in adults and children during surgery, to reduce bleeding; and treatment of acute heart failure to reduce left ventricular end-diastolic pressure, pulmonary capillary wedge pressure, peripheral vascular resistance, and mean arterial blood pressure.

NIPRIDE RTU (sodium nitroprusside), 10 mg/50 mL (0.2 mg/mL), is currently listed in the “Discontinued Drug Product List” section of the Orange Book.

Cardinal Health Regulatory Sciences submitted a citizen petition dated July 15, 2020 (Docket No. FDA-2020-P-1678), under 21 CFR 10.30, requesting that the Agency determine whether NIPRIDE RTU (sodium nitroprusside), 10 mg/50 mL (0.2 mg/mL), was withdrawn from sale for reasons of safety or effectiveness.

After considering the citizen petition and reviewing Agency records and based on the information we have at this time, FDA has determined under § 314.161 that NIPRIDE RTU (sodium nitroprusside), 10 mg/50 mL (0.2 mg/mL), was not withdrawn for reasons of safety or effectiveness. The petitioner has identified no data or other Start Printed Page 14452information suggesting that NIPRIDE RTU (sodium nitroprusside), 10 mg/50 mL (0.2 mg/mL), was withdrawn for reasons of safety or effectiveness. We have carefully reviewed our files for records concerning the withdrawal of NIPRIDE RTU (sodium nitroprusside), 10 mg/50 mL (0.2 mg/mL), from sale. We have also independently evaluated relevant literature and data for possible postmarketing adverse events. We have found no information that would indicate that this drug product was withdrawn from sale for reasons of safety or effectiveness.

Accordingly, the Agency will continue to list NIPRIDE RTU (sodium nitroprusside), 10 mg/50 mL (0.2 mg/mL), in the “Discontinued Drug Product List” section of the Orange Book. The “Discontinued Drug Product List” delineates, among other items, drug products that have been discontinued from marketing for reasons other than safety or effectiveness. ANDAs that refer to NIPRIDE RTU (sodium nitroprusside), 10 mg/50 mL (0.2 mg/mL), may be approved by the Agency as long as they meet all other legal and regulatory requirements for the approval of ANDAs. If FDA determines that labeling for this drug product should be revised to meet current standards, the Agency will advise ANDA applicants to submit such labeling.
