What is the main therapeutic use of sedatives?

Sedatives are primarily used to relieve anxiety by promoting a calming effect on the central nervous system. They achieve this by increasing the activity of certain neurotransmitters, such as gamma-aminobutyric acid (GABA), which helps to inhibit excessive neural activity and induces relaxation. This property makes sedatives particularly valuable in medical settings for patients experiencing anxiety disorders, stress-related conditions, or before surgical procedures to help ease apprehension.

While enhancing mental activity, stopping bleeding, and reducing inflammation are associated with other classes of medications or therapeutic approaches, they are not the main functions of sedatives. The primary focus of sedatives is to manage anxiety, making option B the most accurate choice.
