PDR 全名是 Physician's Desk Reference http://en.wikipedia.org/wiki/Physicians'_Desk_Reference The Physicians' Desk Reference (PDR) is a commercially published compilation of manufacturers' prescribing information (package insert) on prescription drugs, updated annually. While designed to provide physicians with the full legally mandated information relevant to writing prescriptions (just as its name suggests), it is widely available in libraries and bookstores, widely used by other medical specialists, and in significant part valuable to consumers. It is financially supported in part by pharmaceutical manufacturing corporations which create drugs listed within its pages.
