THE MEDICAL LETTER'S DATABASE OF ADVERSE
DRUG INTERACTIONS NOW AVAILABLE ON PDA

NEW ROCHELLE, NY -- October 29, 2002 -- The Medical Letter® has signed an agreement with Skyscape, Inc., to make the Medical Letter's highly regarded Adverse Drug Interactions database, based on its Handbook of Adverse Drug Interactions, available on personal data assistants (PDAs) running the Palm OS® and Windows CE®/Pocket PC operating systems. The new software called DrugIx™ is available for handheld devices from Skyscape and gives the medical community convenient access to interactions between as many as 16 drugs with Palm OS® or an unlimited number of drugs with Pocket PC.

"DrugIx™ provides physicians with rapid access to a highly regarded drug interaction database and will help them to prescribe appropriate nonconflicting drugs, right at the point of patient care," said Gianna Zuccotti, M.D., M.P.H., Deputy Editor of The Medical Letter. "The new software also expands our family of medical information resources for the handheld, giving physicians greater choices in how they receive information."

Unlike other drug interaction databases, The Medical Letter's evidence-based database is clinically oriented and well documented, and generally does not contain theoretical interactions unless they are considered contraindications by the FDA. The resulting report differs from a pharmacy-derived report in that it contains only interactions that have been shown to be clinically significant. The report describes the interaction and its probable mechanism and offers recommendations for clinical management and references to the original reports.

The database is updated and the software rereleased every six months. It is also available as a handbook, published annually, and a CD-ROM program.
"We work with the world's leading medical publishers, using our technology to create handheld versions of the best medical references," said Sandeep Shah, president and CEO of Skyscape. "We expect DrugIx to gain the same tremendous acceptance among the medical community as our other solutions because of the quality of the content provided by The Medical Letter and our ability to give users not just the information they need, but the capability to use it the way they think."

DrugIx is a valuable resource for the growing number of physicians who use a PDA in their clinical practices.
