In general, nitrous oxide is considered:

Nitrous oxide is classified as an anesthetic because it has the ability to induce a state of sedation, analgesia, and general anesthesia, particularly in dental and medical procedures. It is commonly used for its properties that provide pain relief and relaxation, making patients more comfortable during treatments. The mechanism by which nitrous oxide works involves the modulation of neurotransmitter systems in the brain, leading to a decreased perception of pain and anxiety while not inducing a complete loss of consciousness, which is characteristic of general anesthetics.

In clinical settings, nitrous oxide is often combined with oxygen to ensure safety and effectiveness, providing a quick onset and recovery profile that is particularly advantageous in outpatient procedures. Its classification as an anesthetic is crucial for understanding its applications and the safety measures required when used in practice.
