IA#68-08 --- 2/10/87

BACKGROUND

The Center for Veterinary Medicine has received reports that the following
drugs are being used illegally in race horses in this country:

    1.  Healon Injection or Hylartin V (Hyaluronic Acid or Sodium
        Hyaluronate)

    2.  Arteparon (Glucosaminoglycan Polysulfuric Acid Ester)

    3.  Clenbuterol

    4.  Domosedan (Detomidine hydrochloride)

    5.  Circulon (Isoxsuprine hydrochloride)

We routinely receive complaints from state race track authorities about the
illegal use of these drugs.  Although we are not sure exactly how these drugs
enter the country, we suspect they enter in small lots which escape detection.

All of these drugs may legally enter when consigned to the holder of a valid
INAD or approved NADA.  Any product entering which does not conform to the
requirements of an NADA/INAD must be denied entry.  Following are the
specifics of the appropriate NADA/INAD.

     Hylartin V or Healon Injection (Hyaluronic Acid or Sodium
     hyaluronate) (approved NADA 112-048)

     Pharmacia AB, Uppsala, Sweden, is the only source of hyaluronic acid
     provided for in the approved NADA.  Pharmacia Inc., Piscataway, New
     Jersey is the sponsor named in the NADA.  Any hyaluronic acid in import
     status not from Pharmacia and not going to Piscataway, New Jersey, should
     be denied entry.

     According to our information, most of the illegal entries of hyaluronic
     acid originate in Italy.  Pitman-Moore also holds an INAD for hyaluronic
     acid (HYVISC) but they do not receive shipments from foreign sources.

     Arteparon (glycosaminoglycan polysulfated ester) - This is a human
     labeled product produced by Luitpold-Werk, Munich, West Germany, being
     brought into the U.S. illegally for use in race horses.  There is an
     approved NADA 136-383 for the same drug under the trade name Adequan
     manufactured by the same German firm.  The U.S. sponsor is Dr. Lawrence
     Goldman, Jupiter, Florida.

     Clenbuterol (INAD 2227)

     Bohringer Ingelheim Ltd., in Germany is the only source of Clenbuterol
     provided for in the INAD.  Philips Roxanne, Inc., 2621 North Belt
     Highway, St. Joseph, MO, is the sponsor named in the INAD.  Clenbuterol
     should not be coming from any other source or going to any other
     consignee.  Any Clenbuterol in import status not conforming to the above
     should be denied entry.

     Domosedan (Detomidine Hydrochloride) (INAD 2956)

     Domosedan is the trade name of the product approved in England and
     Finland.  Wolfgang Jochle Associates, Inc., Denville, New Jersey, holds
     the INAD on behalf of the Farmos Group Ltd., Turku, Finland.  Any
     detomidine hydrochloride not consigned to Wolfgang Jochle Associates
     should be detained.

     Circulon (Isoxsuprine Hydrochloride) (INAD 2912)

     Circulon is the trade name of the product approved in Australia.  Ceva
     Labs, Overland Park, Kansas is the U.S. Sponsor of Circulon under this
     INAD.  The legal drug is sent to Ceva Labs by Medical Research Pty. Ltd.,
     Sydney, Australia.  Any entries of Isoxsuprine hydrochloride not
     consigned to Ceva should be detained.
