VALLEY FORGE, Pa., Oct 1, 2001 (BUSINESS WIRE) --AmerisourceBergen Corporation (NYSE: ABC) today announced that its Pharmacy Healthcare Solutions (PHS) unit has signed a co-marketing and investment agreement with ClinPharm LLC. ClinPharm develops advanced clinical software programs designed to enhance patient safety and optimize drug therapy.

ClinPharm's primary product, MedStorm(TM), enables pharmacists to easily search and analyze medication profiles and laboratory results to identify patients at risk for medication related adverse events and initiates an automated physician notification process. The program provides pharmacists and physicians with recommendations for optimal care by integrating national guidelines, published recommendations and hospital-specific protocols into its medical logic modules.

"We are excited about the prospect of offering to our customers an efficient and inexpensive system of reducing adverse drug events," commented Allen Zimmerman, President of Pharmacy Healthcare Solutions. "ClinPharm's programs are quite expansive and represent a new generation of proactive software to the market."

During the development stages, MedStorm won an "Innovation in Teaching" award from the American Association of Colleges of Pharmacy and it's founder, Gamal Hussein, Pharm. D., won the prestigious "Health System Practitioner Award" given by the National Pharmaceutical Association. In addition, the International Association of Therapeutic Drug Monitoring has supported and promoted the evaluation of the program by its members in more than 40 countries.

Under the terms of the agreement, PHS will initially take a minority ownership of the company with rights to purchase the remainder of the company during the term of the agreement.

Dr. Hussein stated, "We are pleased that we will be working with PHS and AmerisourceBergen to expand access to MedStorm's innovative technology. This is the best time to unite our efforts to optimize one of America's top healthcare priorities: patient safety."
