Dinitrogen Oxide (NITROUS OXIDE)
Dinitrogen oxide, also known as nitrous oxide, is a small molecule drug in the nitrous oxide class. It is used as an anesthetic and analgesic agent, providing pain relief and sedation. Nitrous oxide is not FDA-approved for any specific indication, but it is widely used in medical and dental procedures. The commercial status of nitrous oxide is complex, as it is not patented, but its use is heavily regulated. Key safety considerations include potential for oxygen displacement, neurotoxicity, and abuse.
