(1) The availability of sections 1-4 of the draft expert panel reports for amphetamines and methylphenidate on November 15, 2004. Written public comments on the draft report must be received by December 29, 2004.
(2) The expert panel meeting for amphetamines and methylphenidate will be held on January 10-12, 2005, at the Holiday Inn Old Town Select Alexandria, Virginia. The public is invited to present oral comments at this meeting.

Draft Expert Panel Reports on Amphetamines and Methylphenidate Available
The CERHR announces the availability of the draft expert panel reports on amphetamines and methylphenidate on November 15, 2004 on the CERHR Web site (http://cerhr.niehs.nih.gov) or in printed text from the CERHR (contact information below). Amphetamines and methamphetamine are central nervous system stimulants. Amphetamine is indicated for the treatment of narcolepsy and attention deficit hyperactivity disorder (ADHD), and methamphetamine is indicated for the treatment of ADHD and for short-term treatment of obesity. These chemicals are available for pharmaceutical use as various salts and enantiomer preparations. The most common proprietary amphetamine preparation is Adderall®, a mixture of d- and l-amphetamine salts in a 3:1 ratio. d-Methamphetamine is used in pharmaceutical preparations in the United States and is also manufactured and used as an illicit drug. Methylphenidate (CAS RN 298-59-9) is a central nervous system stimulant approved by the Food and Drug Administration for the treatment of ADHD and narcolepsy in persons six years and older. d, l-Methylphenidate is marketed under the names Ritalin®, Metadate®, Methylin®, and Concerta®. The d-enantiomer is marketed under the name FocalinTM. The CERHR selected amphetamines and methylphenidate for expert panel evaluation because of widespread usage in children, availability of developmental studies in children and experimental animals, and public concern about the effects of these stimulants on child development.
Each draft expert panel report has the following sections:
1.0 Chemistry, Use, and Human Exposure
2.0 General Toxicological and Biological Effects
3.0 Developmental Toxicity Data
4.0 Reproductive Toxicity Data
5.0 Summary, Conclusions, and Critical Data Needs (to be prepared at expert panel meeting)
Sections 1-4 will be available to the public by the November 15th in PDF format on the CERHR Web site (http://cerhr.niehs.nih.gov) or in hard copy or as a PDF file on compact disk by contacting Dr. Michael Shelby, Director CERHR [NIEHS, 79 T.W.

The expert panel will review the scientific evidence regarding Start Printed Page 62907the potential reproductive and/or developmental toxicity associated with exposure to amphetamines and methylphenidate. The expert panel will review and revise the draft expert panel report and reach conclusions regarding whether exposure to amphetamines and/or methylphenidate is a hazard to human development or reproduction. The expert panel will also identify data gaps and research needs.
This meeting is open to the public and attendance is limited only by the available meeting room space. The meeting will begin at 8:30 a.m. each day.

Background Information About the CERHR
The NTP established the NTP CERHR in June 1998 [Federal Register, December 14, 1998 (Volume 63, Number 239, page 68782)]. The CERHR is a publicly accessible resource for information about adverse reproductive and/or developmental health effects associated with exposure to environmental and/or occupational exposures. Expert panels conduct scientific evaluations of agents selected by the CERHR in public forums.
The CERHR invites the nomination of agents for review or scientists for its expert registry. Information about CERHR and the nomination process can be obtained from its homepage (http://cerhr.niehs.nih.gov) or by contacting Dr. Shelby (contact information provided above). The CERHR selects chemicals for evaluation based upon several factors including production volume, extent of human exposure, public concern, and published evidence of reproductive or developmental toxicity.
CERHR follows a formal, multi-step process for review and evaluation of selected chemicals. The formal evaluation process was published in the Federal Register notice July 16, 2001 (Volume 66, Number 136, pages 37047-37048) and is available on the CERHR web site under “About CERHR” or in printed copy from the CERHR.Start Signature
