Which medication type is described as high-potency tranquilizers used in pharmacological treatment of anxiety disorders?

• A. SSRIs
• B. Beta-blockers
• C. Benzodiazepines
• D. MAO inhibitors

Answer: (C)

High-potency tranquilizers are benzodiazepines, a class of drugs that provide rapid calming effects for anxiety disorders. They work by enhancing the activity of the GABA neurotransmitter in the brain. Specifically, they bind to the GABA-A receptor and increase the likelihood that the chloride channel opens, which makes neurons more inhibited. This leads to quick relief of anxious feelings (anxiolysis), along with sedative, muscle-relaxant, and anticonvulsant properties. Because of their fast onset, benzodiazepines are often used for short-term relief of acute anxiety, panic episodes, or severe situational anxiety. However, they carry risks of dependence, tolerance, and withdrawal, so they’re typically not favored for long-term treatment. SSRIs are antidepressants that treat anxiety more gradually and are usually used long-term, not for immediate calming. Beta-blockers can reduce physical symptoms of anxiety like rapid heartbeat and tremor, especially in performance anxiety, but they don’t produce the central tranquilizing effect. MAO inhibitors are older antidepressants with dietary restrictions and a broader side effect profile, not used as high-potency tranquilizers for anxiety. So, the description fits benzodiazepines.
