Schedules of Controlled Substances; Removal of Exemption Status for Inactive Butalbital Products
The Drug Enforcement Administration (DEA) proposes to revoke the exempted status for certain nonnarcotic prescription products that are currently on DEA's Table of Exempted Pres...
Drug Enforcement Administration, Department of Justice.
ACTION:
Notice of proposed rulemaking.
SUMMARY:
The Drug Enforcement Administration (DEA) proposes to revoke the exempted status for certain nonnarcotic prescription products that are currently on DEA's Table of Exempted Prescription Products list but whose National Drug Code (NDC) is inactive because they are no longer available and/or the company that applied for the exemption no longer exists. If finalized, these products would be removed from DEA's Table of Exempted Prescription Products list, and they would no longer be considered exempt prescription products under the Controlled Substances Act. This action will not impact exempted prescription products with active NDC numbers.

Legal Authority
The Controlled Substances Act (CSA) authorizes the Attorney General, by regulation, to exempt from certain provisions of the CSA any compound, mixture, or preparation containing certain nonnarcotic controlled substances if she finds that it is both (1) approved for prescription use, and (2) contains one or more other active ingredients which are not listed in any schedule and which are included in such combinations, quantity, proportion, or concentration as to vitiate the potential for abuse.[1]
The Attorney General has delegated this authority to the Administrator of DEA (Administrator).[2]
The Administrator may also revoke a previously granted exemption by following the same procedures that are used to evaluate an application for exemption—namely, by publishing in the
Federal Register
a general notice of the proposed rulemaking (NPRM) for revoking the exemption, permitting interested persons to file written comments on or objections to the proposed revocation, considering any comments submitted, and publishing a final order in the
Federal Register
that sets forth the findings of fact and conclusions of law upon which the order is based.[3]
This notice proposes to revoke the exemption status for certain prescription products previously granted exemption because the National Drug Codes (NDCs) of these products are no longer active and/or the companies that originally filed for their exemption are no longer in existence. If finalized, this action will revoke the exemption status for a number of products and remove them from DEA's Table of Exempted Prescription Products list. While this action would revoke the exemption status, this action should have no effect on these products because they are no longer marketed.
Background: Exempted Prescription Products
DEA has exempted prescription drug products from certain parts of the CSA when the products meet the requirements for exemption, including the requirement to contain active ingredients believed to vitiate the potential for abuse. The current table of products that have been granted exempted prescription product status, pursuant to 21 CFR 1308.31 and
( printed page 30528)
1308.32, can be found on the DEA Diversion Control Division website.[4]
Butalbital is classified as an intermediate acting barbiturate. Butalbital is a schedule III nonnarcotic controlled substance that falls under DEA Administration Controlled Substances Code Number 2100, as it is a derivative of barbituric acid.[5]
Originally, some butalbital prescription products were excepted by the Bureau of Drug Abuse Control (BDAC) of the Food and Drug Administration (FDA), the predecessor to the Bureau of Narcotics and Dangerous Drugs and later DEA. A panel of public health physicians and FDA medical officers developed the criteria used to exempt butalbital prescription products by BDAC in 1967. These criteria were based upon the expectation that combining the controlled substance with an amount of counteractive drug sufficient to cause early deterrent side effects would vitiate the potential for abuse. For products containing long or intermediate acting barbiturates in combination with analgesics, the criteria provided that an exception would be granted if, for every 15 mg of barbiturate, the product contained at least (1) 188 mg aspirin; (2) 375 mg salicylamide; or (3) 70 mg phenacetin, acetanilid, or acetaminophen.
Following the establishment of the criteria, DEA approved subsequent applications by new manufacturers based upon the same criteria, whereby the inclusion of these other active ingredients was thought to be in sufficient quantities to vitiate the potential for abuse. The criteria developed in 1967 was originally found to meet the standard for exemption currently described in 21 U.S.C. 811(g)(3)(A), such that if a prescription drug was found to meet the 1967 criteria for exception, then it also met the test to contain an ingredient that vitiated the potential for abuse under the CSA standard.
Currently, there are 189 butalbital products listed by their NDC on DEA's Table of Exempted Prescription Products. Using the FDA's National Drug Code Directory [6]
and the U.S. National Institute of Health-National Library of Medicines DailyMed database,[7]
DEA determined that 160 of the NDCs correlating to butalbital products on the exempt prescription product list are no longer active and marketed. DEA confirmed with FDA these products are no longer marketed. Therefore, DEA is proposing to remove these inactive products from the exempted prescription product list for clarity and to accurately portray which products are currently on the market. DEA welcomes comments from any company who believes their product is being erroneously removed from the exempt prescription product list because their product is still available for sale.

Regulatory Analyses
Executive Orders 12866, 13563, 14192, and 14294
DEA has determined that this proposed rulemaking is not a “significant regulatory action” under section 3(f) of E.O. 12866, Regulatory Planning and Review. This proposed rule has been drafted and reviewed in accordance with E.O. 12866, “Regulatory Planning and Review,” section 1(b), Principles of Regulation and E.O. 13563, “Improving Regulation and Regulatory Review,” section 1(b), General Principles of Regulation. This action is also not subject to E.O. 14192, “Unleashing Prosperity Through Deregulation,” or E.O 14294, “Fighting Overcriminalization in Federal Regulations,” as this action is neither a deregulation nor invokes criminal penalties.
This proposed regulation meets the applicable standards set forth in sections 3(a) and 3(b)(2) of E.O. 12988 to eliminate drafting errors and ambiguity, minimize litigation, provide a clear legal standard for affected conduct, and promote simplification and burden reduction.
This proposed rulemaking does not have federalism implications warranting the application of E.O. 13132. The proposed rule does not have substantial direct effects on the States, on the relationship between the national government and the States, or the distribution of power and responsibilities among the various levels of government.
This proposed rule does not have tribal implications warranting the application of E.O. 13175. It does not have substantial direct effects on one or more Indian tribes, on the relationship between the Federal government and Indian tribes, or on the distribution of power and responsibilities between the Federal government and Indian tribes.
Regulatory Flexibility Act
The Administrator, in accordance with the Regulatory Flexibility Act,[8]
has reviewed this proposed rule and, by approving it, certifies that it will not have a significant economic impact on a substantial number of small entities. There would be no economic impact because the products being removed from DEA's prescription product exempt list are no longer marketed.
Unfunded Mandates Reform Act of 1995
In accordance with the Unfunded Mandates Reform Act (UMRA) of 1995,[9]
DEA has determined and certifies that this action would not result in any Federal mandate that may result “in the expenditure by State, local, and tribal governments, in the aggregate, or by the private sector, of $100,000,000 or more (adjusted annually for inflation) in any 1 year . . . .” Therefore, neither a Small Government Agency Plan nor any other action is required under UMRA of 1995.
( printed page 30532)
Paperwork Reduction Act of 1995
This proposed rule would not impose a new collection of information under the Paperwork Reduction Act of 1995.[10]
Also, this proposed rule would not impose new or modify existing recordkeeping or reporting requirements on State or local governments, individuals, businesses, or organizations.

FDA's NDC directory contains information about finished, unfinished (
e.g.,
active pharmaceutical ingredients) and compounded drugs. The NDC Directory contains product listing data submitted for all finished drugs including prescription and over-the-counter drugs, approved and unapproved drugs as well as repackaged and relabeled drugs. Drug establishments are required to provide FDA with a current list of all drugs, including active pharmaceutical ingredients manufactured, prepared, propagated, compounded, or processed for sale in the United States at their facilities. Drugs are identified and reported using a unique NDC, which serves as the FDA's identifier for drugs. FDA publishes the listed NDC numbers in the NDC directory, which is updated daily. Database queried January 27-February 3, 2026.
