Final answer:
When searching for a drug in the PDR by its brand name, you should consult the Brand Names section to find the relevant page number.
Step-by-step explanation:
If you know the brand name of a drug, you would turn to the Brand Names section of the Physicians' Desk Reference (PDR) to locate the page number where the drug is listed. The PDR is a comprehensive book that healthcare professionals use to find information about drugs. When seeking information on a drug by its brand name, it would not be efficient to look through the generic names or the other sections as they serve very different purposes. The Generic Names section lists drugs alphabetically by their generic name, Dosage Information provides specific details about how a drug is administered, and Special Precautions highlights important safety information about the drug that prescribers need to be aware of.
