Final answer:
Anti-anxiety tranquilizers, like benzodiazepines, are sometimes referred to as minor tranquilizers and are prescribed for reducing anxiety symptoms.
Step-by-step explanation:
Anti-anxiety tranquilizers are sometimes called minor tranquilizers. These medications, such as benzodiazepines, are prescribed to reduce symptoms of anxiety, including panic attacks and intense fear or worry. Benzodiazepines work by affecting the central nervous system, leading to effects like sedation, muscle relaxation, and anticonvulsant activity. Common examples of benzodiazepines include diazepam (Valium), and chlordiazepoxide (Librium). They are used in various situations, including as anxiolytics and hypnotics, and in the management of anxiety disorders. Unlike barbiturates, which also produce a depressant effect on the central nervous system, benzodiazepines are preferred due to their lower risk of addiction and overdose, as well as being effective in treating anxiety and insomnia.
