SUPPLEMENTARY INFORMATION:

Background

On December 31, 2004, the Food and Drug Administration (FDA) approved pregabalin [(S)-3-(aminomethyl)-5-methylhexanoic acid] for marketing under the trade name LyricaTM. LyricaTM will be marketed in the United States as a prescription drug product for the management of neuropathic pain associated with diabetic peripheral neuropathy (DPN) and postherpetic neuralgia (PHN). Pregabalin has recently been placed on the market in some European countries for the treatment of epilepsy and neuropathic pain.

On April 4, 2005, the Acting Assistant Secretary for Health of the Department of Health and Human Services (DHHS), sent the Administrator of the DEA a letter recommending that pregabalin, and its salts, be placed into Schedule V of the CSA. Enclosed with the April 4, 2005, letter was a document prepared by the FDA entitled, ``Basis for the Recommendation for Control of Pregabalin in Schedule V 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)).

Based on the recommendation of the Acting Assistant Secretary for Health and an independent review of the available data by the DEA, the Deputy Administrator of the DEA, in a May 13, 2005, Federal Register Notice of Proposed Rulemaking (70 FR 25502), proposed placement of pregabalin into Schedule V of the CSA. The proposed rule provided an opportunity for all interested persons to submit their comments, objections or requests for hearing to be received by the DEA on or before June 13, 2005.

Comments Received

The DEA received two comments in response to the Notice of Proposed Rulemaking. One commenter stated that the DEA should not minimize the similarity in effects produced by pregabalin and diazepam and should place pregabalin in Schedule IV of the CSA.

The DEA does not agree. Careful consideration of all the available data suggests that pregabalin has less abuse potential than Schedule IV substances. Pregabalin does not substitute for benzodiazepines in benzodiazepine-dependent animals. Data from clinical trials suggest that some of pregabalin's positive psychic effects are limited and do not continue with time or continued drug use. The data are consistent with a substance that could be abused intermittently for reward, but not for reinforcement. In addition, withdrawal effects of pregabalin are less severe than with other substances currently controlled in Schedule IV.

Another commenter stated that, in their experience with pregabalin in clinical trials, pregabalin does not demonstrate any risk that would merit being considered a scheduled drug.

The DEA does not agree. Preclinical studies indicated that pregabalin is transiently and sporadically self-administered at rates greater than vehicle but substantially lower than active comparators pentobarbital (CII) and methohexital (CIV). In clinical trials, pregabalin produces some pharmacological effects characteristic of diazepam and alprazolam and is likely to be abused for its positive psychic effects. The percentage of individuals that experienced acute euphoric effects was unusually high for pregabalin in clinical trials. Pregabalin also produced dizziness, somnolence, dry mouth, edema, blurred vision, weight gain and attentional problems more frequently than placebo. These data suggest that pregabalin does have sufficient abuse potential to warrant control under the CSA. The DHHS recommended control in Schedule V of the CSA and the DEA concurs.

Scheduling of Pregabalin

Relying on the scientific and medical evaluation and 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 the DEA, and after a review of the comments received in response to the Notice of Proposed Rulemaking, the Deputy Administrator of the DEA, pursuant to sections 201(a) and 201(b) of the Act (21 U.S.C. 811(a) and 811(b)), finds that:

(1) Pregabalin has a low potential for abuse relative to the drugs or other substances in Schedule IV;

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

(3) Abuse of pregabalin may lead to limited physical dependence or psychological dependence relative to the drugs or other substances in Schedule IV. (21 U.S.C. 812(b)(5))

Based on these findings, the Deputy Administrator of the DEA concludes that pregabalin, including its salts, and all products containing pregabalin, warrant control in Schedule V of the CSA.

In order to make pregabalin pharmaceutical products available for medical use as soon as possible, the Schedule V controls for pregabalin will be effective July 28, 2005. In the event that the regulations impose special hardships on the registrants, the DEA will entertain any justified request for an extension of time to comply with the Schedule V regulations regarding pregabalin. The applicable regulations are as follows:

Registration. Any person who manufactures, distributes, dispenses, imports, exports, conducts research or instructional activities or chemical analysis or proposes to engage in such activities with pregabalin, must submit an application for Schedule V registration 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 August 29, 2005, and may continue their activities until the DEA has approved or denied that application.

Security. Pregabalin is subject to Schedule III-V security requirements and must be manufactured, distributed and stored in accordance with Sec. Sec. 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 and after July 28, 2005.

Labeling and Packaging. All labels and labeling for commercial containers of pregabalin shall comply with requirements of Sec. Sec. 1302.03-1302.07 of Title 21 of the Code of Federal Regulations. 

Inventory. Every registrant required to keep records and who possesses any quantity of pregabalin must keep an inventory of all stocks of pregabalin on

[[Page 43635]]

hand pursuant to Sec. Sec. 1304.03, 1304.04 and 1304.11 of Title 21 of the Code of Federal Regulations on and after July 28, 2005. Every registrant who desires registration in Schedule V for pregabalin is required to conduct an inventory of all stocks of the substance on hand at the time of registration.

Records. All registrants must keep records pursuant to Sec. Sec. 1304.03, 1304.04, 1304.21, 1304.22, and 1304.23 of Title 21 of the Code of Federal Regulations on and after July 28, 2005.

Prescriptions. All prescriptions for pregabalin or prescriptions for products containing pregabalin must be issued pursuant to 21 CFR 1306.03-1306.06 and 1306.21, 1306.23-1306.27.

Importation and Exportation. All importation and exportation of pregabalin must be in compliance with part 1312 of Title 21 of the Code of Federal Regulations on and after July 28, 2005.

Criminal Liability. Any activity with pregabalin not authorized by, or in violation of, the Controlled Substances Act or the Controlled Substances Import and Export Act occurring on and after July 28, 2005, shall be unlawful.

Regulatory Certifications

Administrative Procedure Act

The Administrative Procedure Act permits an agency to make a rule effective upon the date of publication when the agency finds good cause exists and publishes its findings with the rule (5 U.S.C. 553(d)(3)). As noted previously, on December 31, 2004, the FDA approved pregabalin [(S)-3-(aminomethyl)-5-methylhexanoic acid] for marketing under the trade name Lyrica. On April 4, 2005, the Acting Assistant Secretary for Health of the DHHS sent the Administrator of the DEA a scientific and medical evaluation and a scheduling recommendation that pregabalin, and its salts, be placed in Schedule V of the CSA. Since this is a new drug not previously available in the United States and the first drug product specifically approved for the treatment of neuropathic pain associated with diabetic peripheral neuropathy (DPN) and postherpetic neuralgia (PHN), in order to prevent harm to the public health and safety by delaying the availability of this new drug, the DEA finds good cause to make this Final Rule effective immediately upon publication.

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. 605(b)), 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. Pregabalin products will be prescription drugs used for the treatment of neuropathic pain. Handlers of pregabalin often handle other controlled substances used to treat pain which are already subject to the regulatory requirements of the CSA.

Pregabalin is a new drug in the United States; recent approval of LyricaTM by the FDA will allow it to be marketed once it is placed into Schedule V of the CSA. This final rule will allow medical access to a new pharmaceutical product.

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 $115,000,000 or more 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.

Small Business Regulatory Enforcement Fairness Act of 1996

This rule is not a major rule as defined by Sec. 804 of the Small Business Regulatory Enforcement Fairness Act of 1996. 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.
