what is a PDR
The Physicians' Desk Reference (PDR) is a commercially published compilation of manufacturers' prescribing information (package insert) on prescription drugs, updated annually.n 1984, Paul C. Kranz and Michael Grondin travelled to Oradell, New Jersey, and presented to Medical Economics (then-publisher of the PDR) a prototype developed by Grondin on a TI 99/4A computer of how a digital copy of the PDR would work and benefit clinicians.
