What are drugs primarily used to induce sleep called?

Drugs that are primarily used to induce sleep are classified as hypnotics. These substances act on the central nervous system to produce a state of relaxation and drowsiness, making it easier for individuals to fall asleep and maintain sleep. They are specifically designed to treat sleep disorders such as insomnia and can vary in terms of their duration of action and side effects.

Hypnotics can include a variety of medications, such as benzodiazepines and non-benzodiazepine sleep aids, which are used to help individuals achieve restful sleep. This classification is distinct from other drug types, such as stimulants, which increase alertness and energy, antidepressants that are primarily aimed at alleviating mood disorders, and analgesics that are used to relieve pain. Each of these drug classes serves a very different purpose, illustrating the specific role hypnotics play in sleep management.
