DATE RAPE DRUG COULD HELP FIGHT NARCOLEPSY

WASHINGTON--A government advisory panel decided Wednesday that a drug
abused in date rape can be useful as a treatment for a rare but
dangerous complication of the sleep disorder narcolepsy.

The panel convened by the Food and Drug Administration had been asked
to consider whether prescription sales should be permitted for gamma
hydroxy butyrate, or GHB, under the brand name Xyrem.

The committee voted, 6 to 3, that the manufacturer has shown that the
drug is useful in treating cataplexy, a complication that can cause
people to suddenly collapse when their muscles lose strength.

The vote in effect endorses sales of the drug. The FDA is not
required to follow the recommendations of its advisory panels but
most often does so.

The advisory panel urged that the FDA, if it approves the drug,
develop a strong risk management plan to make sure that the drug does
not get into the wrong hands.

Narcolepsy is marked by recurring episodes of daytime sleep in the
victim, lasting from a few seconds to an hour. A new drug, Provigil,
was recently approved for that condition, and the committee voted
unanimously not to accept Xyrem for general narcolepsy.

Some narcolepsy victims also suffer a cataplexy that can be disabling
and dangerous. If approved by the FDA, Xyrem would be the first
treatment for these people.

GHB, which depresses the central nervous system, originally was
developed as an anesthetic. It later was withdrawn because of
unwanted side effects. Before 1990, it was available in many health
stores until increasing reports surfaced of its abuse as a
recreational drug.

Last year, President Clinton signed a bill toughening federal laws
for possession and distribution of GHB, which has been linked to at
least 58 deaths since 1990 and more than 5,700 recorded overdoses,
according to the Drug Enforcement Administration.

It is sometimes used as a date-rape drug. A few drops of the
colorless, odorless drug are slipped into a drink. A victim who
drinks it can lose consciousness within 20 minutes and often have no
memory of what happened. The drug is difficult to trace, often
leaving the body within 24 hours.

The cause of narcolepsy has eluded researchers, Stimulant drugs help
some victims but can cause side effects. There are about 125,000
narcolepsy patients in the United States.
