Sedative-hypnotics are a class of drugs used to treat anxiety and sleep disorders, but their use is fraught with risks, including dependence, cognitive impairment, and next-day drowsiness. As pharmacists are on the front lines of dispensing these medications, a deep understanding of their pharmacology, risks, and appropriate patient counseling is vital. This quiz for PharmD students will test your knowledge of benzodiazepines, “Z-drugs,” and other agents used to promote sleep, ensuring you are prepared to manage these therapies safely and effectively.
