These agents exert a calming effect and help relax the patient.1 At higher doses, the same drug can produce drowsiness and initiate a relatively normal state of sleep (hypnosis). At still higher doses, some sedative–hypnotics (especially barbiturates) will eventually bring on a state of general anesthesia. Because of their general central nervous system (CNS)–depressant effects, some sedative-hypnotic drugs are also used for other functions, such as treating epilepsy or producing muscle relaxation.
