Feedback:
The adverse effects caused by barbiturates are more severe than those associated with other, newer sedatives/hypnotics. For this reason, barbiturates are no longer considered the mainstay for the treatment of anxiety. In addition, the development of physical tolerance and psychological dependence is more likely with the barbiturates than with other anxiolytics. The most common adverse effects are related to central nervous system (CNS) depression. Hypersensitivity reactions to barbiturates are sometimes fatal.
