Drug Enforcement Administration, Department of Justice.
Notice of proposed rulemaking.
This proposed rule is issued by the Deputy Administrator of the Drug Enforcement Administration (DEA) to place the substance carisoprodol, including its salts, isomers, and salts of isomers whenever the existence of such salts, isomers, and salts of isomers is possible, into schedule IV of the Controlled Substances Act (CSA). This proposed action is based on a recommendation from the Acting Assistant Secretary for Health of the Department of Health and Human Services (DHHS) and on an evaluation of the relevant data by DEA. If finalized, this action would impose the regulatory controls and criminal sanctions of schedule IV on those who handle carisoprodol and products containing carisoprodol.

Carisoprodol is a centrally acting muscle relaxant and is indicated for the relief of discomfort associated with acute, painful musculoskeletal conditions. Carisoprodol has been available since 1959 as a prescription drug in the United States under the trade name Soma®. It is also marketed as generic products. Carisoprodol is similar to a variety of central nervous system (CNS) depressants, including meprobamate (C-IV) and chlordiazepoxide (C-IV). The actual abuse data from several databases demonstrate that carisoprodol is abused in the United States. Because of growing concerns about abuse of carisoprodol, a number of states have regulated carisoprodol under their controlled substance regulations, and a number of additional states are currently considering such regulation.
Because of the evidence relating to diversion, abuse, and trafficking of carisoprodol, in March 1996, the DEA requested from the DHHS a scientific and medical evaluation and a scheduling recommendation for carisoprodol, in accordance with 21 U.S.C. 811(b).
In February 1997, the U.S. Food and Drug Administration (FDA) Drug Abuse Advisory Committee (DAAC) deliberated upon the abuse and scheduling issues and concluded that the data were insufficient to control carisoprodol under the CSA at that time. Since the FDA DAAC meeting, pharmacological studies addressing the abuse liability of carisoprodol have been conducted under the direction of the National Institute on Drug Abuse (NIDA) and the College on Problems of Drug Dependence (CPDD). DEA acquired new carisoprodol-related data on actual abuse, law enforcement encounters and other information and sent this supplementary information to DHHS on November 14, 2005. FDA acquired new data from the Drug Abuse Warning Network (DAWN), National Survey on Drug Use and Health (NSDUH), Florida Medical Examiners Commission reports, FDA's Adverse Event Reporting System (AERS) and information from the published scientific literature and conducted a scientific and medical evaluation. These data collectively indicate that carisoprodol has abuse potential and is being diverted, trafficked, with increasing frequency and magnitude.
Carisoprodol abuse has been associated with increasing numbers of emergency department (ED) visits in recent years as indicated by DAWN. The “abuse frequency,” calculated as ED visits per 10,000 prescriptions, of carisoprodol (frequency range during 2002-2007: 15.1 to 22.6 visits/10,000 prescriptions) is similar to that of a schedule IV drug, diazepam (frequency range during 2002-2007: 12.5 to 14.1 visits/10,000 prescriptions). Carisoprodol is used as either the sole drug or in combination with other substances such as opioids, benzodiazepine, alcohol, marijuana, and cocaine. Data from the AERS database show that carisoprodol is associated with adverse health events including dependence and withdrawal syndrome.
The data from National Poison Data System of the American Association of Poison Control Centers documented 8,821 carisoprodol toxic exposure cases including 3,605 cases in which it was Start Printed Page 59110the sole drug mentioned in 2007. Medical Examiners Commission Reports released by the Florida Department of Law Enforcement (FDLE) indicate that carisoprodol/meprobamate related deaths in Florida increased by 100 percent from 208 deaths in 2003 to 415 deaths in 2008.
The National Forensic Laboratory Information System (NFLIS), a DEA system that tracks analyzed drug exhibits submitted by the federal, state, and local law enforcement, documented evidence of substantial diversion of carisoprodol. For example, law enforcement submitted a total of 3,873 carisoprodol drug items to participating forensic laboratories in 2008. NFLIS consistently listed carisoprodol in the top 25 most frequently identified drugs since 2000. The 2007 NSDUH data show that 2.7 million individuals used Soma® in their lifetime (i.e., ever used) for a non-medical purpose.
The data from in vitro electrophysiological studies using the whole-cell patch clamp technique demonstrate that carisoprodol elicits barbiturate-like effects. Intravenous drug self-administration studies in rhesus monkeys show that carisoprodol has positive reinforcing effects. Meprobamate, pentobarbital, and chlordiazepoxide substitute fully for the discriminative stimulus effects of carisoprodol in rats. Bemegride, a barbiturate antagonist, antagonizes the discriminative stimulus effects of carisoprodol.
Data from an animal study indicates that carisoprodol has dependence liability similar to barbital (schedule IV), a central nervous system depressant. Carisoprodol administered orally fully prevented the appearance of abstinence phenomena in dogs tolerant and dependent on barbital. Several published reports document evidence of tolerance and dependence to carisoprodol and indicate the occurrence of abstinence symptoms during carisoprodol withdrawal in humans.
On October 6, 2009, the Acting Assistant Secretary for Health, DHHS, sent the Deputy Administrator of DEA a scientific and medical evaluation and a letter recommending that carisoprodol be placed into schedule IV of the CSA. Enclosed with the October 6, 2009, letter was a document prepared by the FDA entitled, “Basis for the Recommendation for Control of Carisoprodol in Schedule IV of the Controlled Substances Act (CSA).” The document contained a review of the factors which the CSA requires the Secretary to consider (21 U.S.C. 811(b)). The factors considered by the Assistant Secretary of Health and DEA 21 U.S.C. 811(c)) with respect to carisoprodol were:
(1) Its actual or relative potential for abuse;
(2) Scientific evidence of its pharmacological effects;
(3) The state of current scientific knowledge regarding the drug;
(4) Its history and current pattern of abuse;
(5) The scope, duration, and significance of abuse;
(6) What, if any, risk there is to the public health;
(7) Its psychic or physiological dependence liability; and
(8) Whether the substance is an immediate precursor of a substance already controlled under this subchapter.
Based on the recommendation of the Assistant Secretary for Health, received in accordance with section 201(b) of the Act (21 U.S.C. 811(b)), and the independent review of the available data by DEA, the Deputy Administrator of DEA, pursuant to sections 201(a) and 201(b) of the Act (21 U.S.C. 811(a) and 811(b)), finds that:
1. Carisoprodol has a low potential for abuse relative to the drugs or other substances in Schedule III. Animal studies indicate that carisoprodol is similar to schedule IV drugs such as meprobamate and chlordiazepoxide in its central nervous system depressant effects. The documented data on law enforcement encounters and actual abuse of carisoprodol demonstrate that it has a potential for abuse and is being diverted and abused. Since 2000, DEA's NFLIS database consistently mentioned carisoprodol in the top 25 drugs that were most frequently identified by state and local forensic laboratories thereby indicating that carisoprodol is being diverted. Emergency department visits data from DAWN indicate that abuse frequency of carisoprodol is similar to that of diazepam, a schedule IV drug. Recent data from DAWN medical examiner reports and emergency department visits showed an increase in carisoprodol abuse.
2. Carisoprodol has a currently accepted medical use in treatment in the United States. Carisoprodol is an FDA approved drug and is used for the relief of discomfort associated with acute, painful musculoskeletal conditions.
3. Abuse of carisoprodol may lead to limited physical dependence or psychological dependence relative to the drugs or other substances in schedule III. Carisoprodol, similar to barbital (schedule IV), prevents the abstinence syndrome in drug withdrawn barbital-dependent dogs. Published reports indicate that carisoprodol causes psychological or physical dependence and withdrawal syndrome.
Based on these findings, the Deputy Administrator of DEA concludes that carisoprodol, including its salts, isomers, and salts of isomers whenever the existence of such salts, isomers, and salts of isomers is possible warrants control in schedule IV of the CSA. (21 U.S.C. 812(b)(4))
References to the above studies and data may be found in the Health and Human Services scheduling recommendation and DEA's independent analysis, both of which are available on the electronic docket associated with this rulemaking.
Requirements for Handling Carisoprodol
If this rule is finalized as proposed, carisoprodol would be subject to CSA regulatory controls and administrative, civil, and criminal sanctions applicable to the manufacture, distribution, dispensing, importing, and exporting of a schedule IV controlled substance, including the following:
Registration. Any person who manufactures, distributes, dispenses, imports, exports, engages in research or conducts instructional activities with carisoprodol, or who desires to manufacture, distribute, dispense, import, export, engage in instructional activities or conduct research with carisoprodol, would need to be registered to conduct such activities in accordance with 21 CFR part 1301.
Security. Carisoprodol would be subject to schedules III-V security requirements and would need to be manufactured, distributed, and stored in accordance with 21 CFR 1301.71, 1301.72(b), (c), and (d), 1301.73, 1301.74, 1301.75(b) and (c), 1301.76, and 1301.77.
Labeling and Packaging. All labels and labeling for commercial containers of carisoprodol which are distributed on or after finalization of this rule would need to comply with requirements of 21 CFR 1302.03-1302.07.
Inventory. Every registrant required to keep records and who possesses any quantity of carisoprodol would be required to keep an inventory of all stocks of carisoprodol on hand pursuant to 21 CFR 1304.03, 1304.04 and 1304.11. Every registrant who desires registration in schedule IV for carisoprodol would be required to conduct an inventory of all stocks of the substance on hand at the time of registration.
Records. All registrants would be required to keep records pursuant to 21 Start Printed Page 59111CFR 1304.03, 1304.04, 1304.21, 1304.22, and 1304.23.
Prescriptions. All prescriptions for carisoprodol or prescriptions for products containing carisoprodol would be required to be issued pursuant to 21 CFR 1306.03-1306.06 and 1306.21, 1306.22-1306.27.
Importation and Exportation. All importation and exportation of carisoprodol would need to be in compliance with 21 CFR part 1312.
Criminal Liability. Any activity with carisoprodol not authorized by, or in violation of, the Controlled Substances Act or the Controlled Substances Import and Export Act occurring on or after finalization of this proposed rule would be unlawful.
Executive Order 12866
In accordance with the provisions of the CSA (21 U.S.C. 811(a)), this action is a formal rulemaking “on the record after opportunity for a hearing.” Such proceedings are conducted pursuant to the provisions of 5 U.S.C. 556 and 557 and, as such, are exempt from review by the Office of Management and Budget pursuant to Executive Order 12866, section 3(d)(1).
Regulatory Flexibility Act
The Deputy Administrator hereby certifies that this rulemaking has been drafted in accordance with the Regulatory Flexibility Act (5 U.S.C. 601-612), has reviewed this regulation, and by approving it certifies that this regulation will not have a significant economic impact on a substantial number of small entities.
In considering the impact on small entities, the first question is whether a substantial number of small entities are affected. In this instance, the entities affected are those now selling carisoprodol-containing products without registration. DEA has identified 22 firms manufacturing carisoprodol-containing products in 2009. Fifteen of these firms have existing DEA registrations. This leaves seven firms from this data set selling carisoprodol without registration. DEA has no information on the number of non-registrants distributing or importing carisoprodol, but there is every reason to believe that the number of such firms is well in excess of the seven already identified. The Small Business Administration size standard for a small wholesaler of drugs is 100 employees. It is clearly possible to operate a drug distributing firm with fewer than 100 employees. There can be no question that a substantial number of small entities will be affected by this rule.
The impact on non-registrants now selling carisoprodol will occur in two forms: the cost of registration and the cost of meeting the security requirements in 21 CFR part 1301. There is also a potential impact on firms not now selling carisoprodol who might have wished to enter the market.
The annual registration fee for a distributor, importer, or exporter is $1,147. There is some uncertainty in estimating the cost of meeting the security requirements, because most nonregistrants already meet the security requirements, at least in part, for schedule III and IV substances. To be conservative, it is assumed that every nonregistrant will have to buy a safe to store carisoprodol. A safe with capacity of 13.5 cubic feet should be adequate. A safe of this size may be purchased for $1,350. Annualized over 15 years at 7.0 percent, that is $148 per year. Total annual cost of compliance with the rule, then, is $1,295. The usual standard for a significant economic impact is 1.0 percent of revenue. For $1,295 per year to be a significant economic impact, annual revenue of a firm would have to be under $130,000. Any firm in the business of distributing drugs needs annual revenue well in excess of that amount to sustain itself.
It should be acknowledged that, for a small firm, there may be some inconvenience and expense in preparing necessary forms for registration and registration renewal. These are minor costs. There are also recordkeeping requirements, but these impose little or no incremental cost for a firm that is already maintaining records needed for a wholesale business. The costs of registration and security requirements will not be a significant economic impact.
If a firm chose not to register and to drop its carisoprodol line, the cost to the firm would exceed its earnings on the carisoprodol sales. The firm might also lose some customers who do not want to buy from a vendor without carisoprodol in its product line. A competent manager will recognize this cost. In light of the very small cost of registering, he would presumably choose to drop carisoprodol from the firm's products only if the firm were earning a negligible profit from that line and he judged that dropping it would not turn away significant customers. In light of the foregoing analysis, DEA finds that this rule will not have a significant economic impact on a substantial number of small entities. DEA has no information regarding the number of persons who may distribute carisoprodol-containing products, but do not manufacture, package, repackage, or relabel those products. Therefore, DEA seeks comment on any entities that might be affected by this control action.
This regulation meets the applicable standards set forth in Sections 3(a) and 3(b)(2) of Executive Order 12988 Civil Justice Reform.
This rulemaking does not preempt or modify any provision of state law; nor does it impose enforcement responsibilities on any state; nor does it diminish the power of any state to enforce its own laws. Accordingly, this rulemaking does not have federalism implications warranting the application of Executive Order 13132.
Unfunded Mandates Reform Act of 1995
This rule will not result in the expenditure by state, local, and tribal governments, in the aggregate, or by the private sector, of $120,000,000 or more (adjusted for inflation) in any one year, and will not significantly or uniquely affect small governments. Therefore, no actions were deemed necessary under the provisions of the Unfunded Mandates Reform Act of 1995.
Congressional Review Act
This rule is not a major rule as defined by section 804 of the Small Business Regulatory Enforcement Fairness Act of 1996 (Congressional Review Act). This rule will not result in an annual effect on the economy of $100,000,000 or more; a major increase in costs or prices; or significant adverse effects on competition, employment, investment, productivity, innovation, or on the ability of United States-based companies to compete with foreign based companies in domestic and export markets.Start List of Subjects
