Depressants are substances that primarily work by slowing down the activity of the central nervous system (CNS). This action results in a decrease in brain activity, which can lead to effects such as relaxation, sedation, and alleviation of anxiety. By inhibiting neural activity, depressants can diminish alertness, impair motor skills, and result in slowed reaction times.

For instance, medications like benzodiazepines and alcohol are common depressants that help manage anxiety or induce sleep by suppressing certain functions of the CNS. The term "inhibit" accurately reflects this characteristic, as it conveys the notion of reducing or restraining the normal functioning of neurological activity, leading to the calming effects associated with these substances. Understanding this mechanism is crucial for recognizing the potential risks associated with the use of depressants, including the risk of overdose and dependency.
