Correct Response: B. The Physicians' Desk Reference (PDR) Consumer Drug Information website includes information on nearly all prescription drugs, and its huge database is searchable by drug, health condition, and disease. An A-Z guide includes substantial information on each drug, including its purpose, benefits, usual dosages, side effects, who should or should not take it, what to avoid while taking it, and food and drug interactions. Although the PDR publishes articles, health news, and consumer tips, it does not provide lists of drugs approved and covered by specific health insurance plans (A), examine marketing techniques and research studies used to promote newly patented drugs (C), or assess the reasonability of prices charged by local retailers for particular drugs (D).
