Pharmaceutical Marketing Services

Pharmaceutical Marketing Services Inc. (PMSI) was a leading provider of market research and data services to the pharmaceutical and healthcare industries. Founded in 1991 as a spin-off from Walsh International, the company specialized in tracking prescription data and providing physician-level marketing insights through its subsidiary, Scott-Levin. PMSI became a publicly traded entity on NASDAQ under the symbol PMKS before being acquired by IMS Health (now IQVIA) in 1999 for approximately $290 million. The acquisition significantly expanded IMS Health's capabilities in specialized pharmaceutical data and physician profiling, consolidating major sources of pharmaceutical market intelligence.
