Which of the following is a characteristic of Sedative-Hypnotics?

• A. Increase alertness
• B. Decrease anxiety
• C. Stimulate the CNS
• D. Cause hallucinations

Answer: (B)

Sedative-hypnotics are a class of drugs that primarily have the effect of calming the body and mind, making them effective for decreasing anxiety and promoting sleep. They work by enhancing the effects of the neurotransmitter gamma-aminobutyric acid (GABA) in the central nervous system, which leads to a tranquilizing effect that is often used in the treatment of anxiety disorders, insomnia, and other conditions that require sedation. The characteristic of decreasing anxiety aligns directly with the pharmacological properties of these substances, as they serve to provide relief from anxiety symptoms. In therapeutic contexts, this is often their primary use, making it a defining feature of sedative-hypnotics. Other options do not accurately describe sedative-hypnotics. For example, increasing alertness is associated with stimulant drugs, not sedatives. Stimulants act to enhance alertness and energy levels, which contrasts with the sedative effects of the drugs in question. Additionally, sedative-hypnotics do not stimulate the central nervous system; on the contrary, they depress it, leading to relaxation and sedation. Lastly, causing hallucinations is more commonly associated with hallucinogens or certain other drugs, rather than sedative-hypnotics, which generally
