The Physicians' Desk Reference provides information about drugs approved by the Federal Drug Administration, including dosage, clinical trials and side effects. In American Psychological Association format, it is cited like a book without an author.
Within a scholarly paper, information from the PDR is cited inside parentheses. The title is italicized and followed by a comma and the publication year, such as: (Physicians' Desk Reference, 2013). If the information concerns a specific drug, its name inside quotation marks is used instead of the title.
An APA style paper has a "References" page listing sources of in-text citations. The title, in sentence case, is in italics, followed by a period. Inside parentheses is the edition number, with "edition" abbreviated "ed." Then there's a period. The publication year is in parentheses. After another period, comes the publication location, a colon, the publisher and a period. For example: Physicians' desk reference. (67th ed.). (2013). Montvale, NJ: PDR Network.
Specific Drug Reference
A reference to a drug has its capitalized name followed by a period. The year of publication is within parentheses. There's another period, then "In" is followed by the italicized PDR title in sentence case. Within parentheses is the edition number. There's a comma, and "p." for "page" or "pp." for "pages" is followed by the page number or numbers separated with a hyphen; then there's a period. The publishing information is the same as for a book reference. For example: Xanax. (2013). In Physicians' desk reference (67th ed., pp. 1987-1990). Montvale, NJ: PDR Network.
A reference for the PDR electronic version has the capitalized name of the drug and then a period. Next comes the website publication date in parentheses and another period. Finally, "Retrieved from" is followed by the URL.
