Nitrous Oxide has the longest continuous usage compared to any other drug?

Nitrous oxide is well-known for its extensive and continuous usage in various medical and dental practices, making it a common anesthetic agent throughout history. Its long-standing application can be traced back to the 19th century, when it was first used in surgeries and subsequently adopted in dentistry for its analgesic and anxiolytic properties.

The advantage of nitrous oxide lies in its rapid onset and recovery profile, allowing patients to regain consciousness quickly after its administration. This makes it not only effective but also convenient for numerous procedures, which has contributed to its sustained popularity over time.

When considering the context, while other anesthetic agents have also been used for many years, few have the same breadth of application across various fields, including both dental and surgical settings. Nitrous oxide’s history and versatility solidify its position as a drug with prolonged and continuous usage compared to its counterparts.
