Biosite(R) Announces FDA Clearance to Market Triage(R) TOX Drug Screen

SAN DIEGO, July 13 (HSMN NewsFeed) -- Biosite® Incorporated (Nasdaq: BSTE ), a research-based provider of novel, Rapid Medical diagnostics, today announced it has received U.S. Food and Drug Administration (FDA) clearance to add methadone to its Triage® TOX Drug Screen. The addition of methadone expands the Triage TOX Drug Screen menu to cover 10 drug classes, all of which can be accurately and simultaneously detected within approximately 15 minutes. In 2004, there were nearly 2 million drug-related emergency department visits in the United States, of which more than 30,000 visits were estimated to be associated with methadone use or abuse(1).

"Many drugs, such as methadone, can dangerously interact with other medications, which can put patients at risk if the substances in their body are not accurately identified in a timely manner," said Norman Paradis, M.D., Biosite's vice president, clinical and medical affairs. "The Triage TOX Drug Screen is a rapid and easy-to-interpret device that may allow physicians to make quicker treatment decisions."

Methadone is a medication affecting the central nervous system that is used by clinics and hospitals as a treatment of narcotic withdrawal and dependence. Methadone relieves withdrawal symptoms from heroin, morphine and other opioid drugs and reduces an addict's opiate craving(2).

With this FDA clearance, Biosite will offer the Triage TOX Drug Screen with analytes covering 10 major classes of drugs for the qualitative determination of acetaminophen/paracetamol, amphetamines, methamphetamines, barbiturates, benzodiazepines, cocaine, methadone, opiates, phencyclidine, THC and tricyclic antidepressants.

Shipments of the Triage TOX Drug Screen are expected to commence in the second half of 2006. The tests will be available in countries internationally upon approval by the local regulatory agencies.
