Which of the following drugs is considered to be a nonbarbituate sedative/hypnotic?

a. meperidine (Demerol)
b. midazolam (Versed)
c. propofol (Diprivan)
d. diazepam (Valium)

c. Nonbarbiturates are more widely used because they have fewer side effects, including less cardiac depression. Propofol (Diprivan) is widely used because it is associated with rapid recovery without hangover and nausea and vomiting. Propofol is a nonbarbiturate sedative/hypnotic agent and the most recently developed intravenous anesthetic (1989) that is used for induction of general anesthesia or for maintenance of a balanced anesthesia technique and also for moderate sedation in mechanically ventilated patients.
