AGENCY:

Drug Enforcement Administration, Department of Justice.

ACTION:

Final rule.

SUMMARY:

With the issuance of this final rule, the Deputy Administrator of the Drug Enforcement Administration (DEA) places the substance fospropofol, 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). As a result of this rule, the regulatory controls and criminal sanctions of schedule IV will be applicable to the manufacture, distribution, dispensing, importation, and exportation of fospropofol and products containing fospropofol.

DATES:

Effective Date: November 5, 2009.

Background

On December 12, 2008, the Food and Drug Administration (FDA) approved fospropofol for marketing under the trade name Lusedra® in the United States as a drug product indicated for monitored anesthesia care (MAC) sedation in adult patients undergoing diagnostic or therapeutic procedures.

Fospropofol, 2,6-diisopropopylphenoxymethyl phosphate disodium, is a water soluble, phosphono-O-methyl prodrug of propofol. It is metabolized in the body to propofol, the active metabolite. Propofol has been available for medical use in the United States since 1989 and is not currently a controlled substance. The pharmacological effects of fospropofol are attributed to the pharmacological actions of propofol. Propofol binds to γ-aminobutyric acid (GABAA) receptor and acts as a modulator by potentiating the activity of GABA at this receptor.

Since propofol is the active metabolite of fospropofol, the abuse potential of fospropofol is comparable to that of propofol. Animal self-administration studies demonstrated that the reinforcing effects of propofol are relatively low and comparable to midazolam and other schedule IV benzodiazepines. Fospropofol elicits behavioral effects similar to methohexital and midazolam, schedule IV sedative-hypnotics.

Since fospropofol is a new molecular entity, there has been no evidence of diversion, abuse, or law enforcement encounters involving the drug.

On February 27, 2009, the Acting Assistant Secretary for Health, Department of Health and Human Services (DHHS), sent the Deputy Administrator of DEA a scientific and medical evaluation and a letter recommending that fospropofol be placed into schedule IV of the CSA. Enclosed with the February 27, 2009, letter was a document prepared by the FDA entitled, “Basis for the Recommendation for Control of Fospropofol and Its Salts 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)).

After a review of the available data, including the scientific and medical evaluation and the scheduling recommendation from DHHS, the Deputy Administrator of the DEA published a Notice of Proposed Rulemaking entitled “Schedules of Controlled Substances: Placement of Fospropofol into Schedule IV” on July 23, 2009 (74 FR 36424), which proposed placement of fospropofol into schedule IV of the CSA. The proposed rule provided an opportunity for all interested persons to submit their written comments on or before August 24, 2009.

Comments Received

The DEA received two comments in response to the Notice of Proposed Rulemaking. One comment received from a concerned citizen did not relate to fospropofol, the substance that is being controlled. Thus DEA did not consider this comment.Start Printed Page 51235

Another comment received from a professional organization of anesthesiologists is in agreement with the findings of scientific and medical evaluation that formed the basis for the present rule controlling fospropofol as a schedule IV substance and it fully supported this control action.

Scheduling of Fospropofol

Based on the recommendation of the Acting 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) Fospropofol has a low potential for abuse relative to the drugs or substances in schedule III. Although there is no direct comparison to a schedule III substance, this finding is based on the demonstration of the abuse potential of propofol, the active metabolite, relative to the schedule IV substances, methohexital and midazolam;

(2) Fospropofol has a currently accepted medical use in treatment in the United States; and

(3) Abuse of fospropofol may lead to limited physical dependence or psychological dependence relative to the drugs or other substances in schedule III. This finding is based on the symptoms exhibited upon withdrawal from propofol.

Based on these findings, the Deputy Administrator of DEA concludes that fospropofol, 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))

Requirements for Handling Fospropofol

Registration. Any person who manufactures, distributes, dispenses, imports, exports, engages in research or conducts instructional activities with fospropofol, or who desires to manufacture, distribute, dispense, import, export, engage in instructional activities or conduct research with fospropofol, must be registered to conduct such activities in accordance with part 1301 of Title 21 of the Code of Federal Regulations. Any person who is currently engaged in any of the above activities and is not registered with DEA must submit an application for registration on or before November 5, 2009 and may continue their activities until DEA has approved or denied that application.

Security. Fospropofol is subject to schedules III-V security requirements and must be manufactured, distributed, and stored in accordance with §§ 1301.71, 1301.72(b), (c), and (d), 1301.73, 1301.74, 1301.75(b) and (c), 1301.76, and 1301.77 of Title 21 of the Code of Federal Regulations on or after November 5, 2009.

Regulatory Certifications

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, in accordance with the Regulatory Flexibility Act (5 U.S.C. 601-612), has reviewed this final rule and by approving it certifies that it will not have a significant economic impact on a substantial number of small entities. Fospropofol products will be used for monitored anesthesia care (MAC) sedation in adult patients undergoing diagnostic or therapeutic procedures. Handlers of fospropofol also handle other controlled substances used for sedation which are already subject to the regulatory requirements of the CSA.

Executive Order 12988

This regulation meets the applicable standards set forth in Sections 3(a) and 3(b)(2) of Executive Order 12988 Civil Justice Reform.

Executive Order 13132

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 provisions of the Unfunded Mandates Reform Act of 1995.

Congressional Review Act

This rule is not a major rule as defined by § 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.
