SUPPLEMENTARY INFORMATION:

The United States is a party to the 1971 Convention on Psychotropic Substances (the Psychotropic Convention). Article 2 of the Psychotropic Convention provides that if a party to the convention or WHO has information about a substance, which in its opinion may require international control or change in such control, it should notify the Secretary General of the United Nations (the Secretary-General) and provide the Secretary-General with information in support of its opinion.

The CSA (21 U.S.C. 811 et seq.) (Title II of the Comprehensive Drug Abuse Prevention and Control Act of 1970) provides that when WHO notifies the United States under Article 2 of the Psychotropic Convention that it has information that may justify: (1) Adding a drug or other substances to one of the schedules of the convention, (2) transferring a drug or substance from one schedule to another, or (3) deleting it from the schedules, the Secretary of State must transmit the notice to the Secretary of Health and Human Services (the Secretary of HHS). The Secretary of HHS must then publish the notice in the Federal Register and provide opportunity for interested persons to submit comments that HHS will consider in its preparation of the scientific and medical evaluations of the drug or substance.

II. Background

Gamma-hydroxybutyric acid (GHB) is classified as a central nervous system depressant. In 2002, FDA approved a GHB-containing product, Xyrem, for the treatment of cataplexy associated with narcolepsy. Xyrem was approved under the regulations in 21 CFR 314.520, and the product labeling contained a comprehensive risk management program, which includes restricted distribution of the drug through a central pharmacy. Xyrem is controlled domestically in Schedule III of the CSA, while bulk GHB and all other material containing GHB is controlled in Schedule I. In addition, illicit use of Xyrem is subject to Schedule I penalties of the CSA. GHB is controlled internationally in Schedule IV of the Psychotropic Convention. The WHO Expert Committee on Drug Dependence pre-reviewed GHB at its thirty-fourth meeting and recommended it for critical review at a future meeting.

Ketamine is classified as a rapid-acting general anesthetic agent used for short diagnostic and surgical procedures that do not require skeletal muscle relaxation. It is marketed in the United States as an injectable. Ketamine is controlled domestically in Schedule III of the CSA. It is not controlled internationally under the Psychotropic Convention or the Single Convention on Narcotic Drugs. The WHO Expert Committee on Drug Dependence reviewed ketamine at its thirty-fourth meeting, and recommended that the Secretariat produce an updated version of the critical review for ketamine and present it to the next meeting of the WHO Expert Committee on Drug Dependence.

Dextromethorphan is classified as an oral antitussive agent for treating uncomplicated, nonproductive coughs. It is marketed in the United States without a prescription in mixtures such as syrups, lozenges, or in combination with antihistamines. Dextromethorphan is not controlled domestically or controlled internationally under the Psychotropic Convention or the Single Convention on Narcotic Drugs.

N-benzylpiperazine (BZP) is used as an intermediate in chemical synthesis, but has been taken orally as either powder or tablets and by other routes including smoking or snorting. It has no medical use in the United States. BZP is controlled domestically in Schedule I of the CSA. BZP is not controlled internationally under the Psychotropic Convention or the Single Convention on Narcotic Drugs.

1-(3-trifluoromethylphenyl)piperazine (TFMPP) is a piperazine-based serotonin receptor agonist. It has no medical use in the United States. TFMPP is not controlled domestically or controlled internationally under the Psychotropic Convention or the Single Convention on Narcotic Drugs.

1-(3-chlorophenyl)piperazine (mCPP) is a piperazine-based serotonin receptor agonist. It has no medical use in the United States. mCPP is not controlled domestically or controlled internationally under the Psychotropic Convention or the Single Convention on Narcotic Drugs.

1-(4-Methoxyphenyl)piperazine (MeOPP) is a piperazine-based derivative. It has no medical use in the United States. MeOPP is not controlled domestically or controlled internationally under the Psychotropic Convention or the Single Convention on Narcotic Drugs.

1-(3,4-methylenedioxybenzyl)piperazine (MDBP) is a piperazine derivative with no medical use in the United States. It is not controlled domestically or controlled internationally under the Psychotropic Convention or the Single Convention on Narcotic Drugs.

Gamma-butyrolactone (GBL) is used as a solvent and reagent in chemistry. GBL can be used in the synthesis of GHB, and can be converted to the central nervous system depressant drug Gamma-hydroxybutyric acid (GHB) in the body after ingestion. As a precursor in the manufacture of GHB, GBL is controlled domestically as a List I chemical in the United States under the CSA. It is not controlled internationally under the Psychotropic Convention or the Single Convention on Narcotic Drugs.

1,4-Butanediol is used as an industrial solvent for manufacturing and also used for the synthesis of GBL. After ingestion, 1,4-Butanediol can also be converted to the central nervous depressant drug GHB. It has no medical use in the United States. 1,4-Butanediol is not controlled domestically under the CSA in the United States, but is subject to controls in several states under State law.

III. Opportunity to Submit Domestic Information

As required by section 201(d)(2)(A) of the CSA (21 U.S.C. 811(d)(2)(A)), FDA, on behalf of HHS, invites interested persons to submit comments regarding the 10 named drugs. HHS will consider any received comments when it prepares a scientific and medical evaluation of these drugs. HHS will forward a scientific and medical evaluation of these drugs to WHO, through the Secretary of State, for WHO's consideration in deciding whether to recommend international control/decontrol of any of these drugs. Such control could limit, among other things, the manufacture and distribution (import/export) of these drugs and could impose certain recordkeeping requirements on them.

HHS will not now make any recommendations to WHO regarding whether any of these drugs should be subjected to international controls. Instead, HHS will defer such consideration until WHO has made official recommendations to the Commission on Narcotic Drugs, which are expected to be made in early 2010. Any HHS position regarding international control of these drugs will be preceded by another Federal Register notice soliciting public comments as required by section 201(d)(2)(B) of the CSA.

IV. Comments

Interested persons may submit to the Division of Dockets Management (see ADDRESSES) written or electronic comments regarding the drugs by (see DATES). This abbreviated comment period is necessary to allow sufficient time to prepare and submit the domestic information package by the deadline imposed by WHO. Two paper copies of any comments are to be submitted, except that individuals may submit one paper copy. Comments are to be identified with the docket number found in brackets in the heading of this document.
