What is Ketamine?

Ketamine in an anesthetic developed in the early 1960s. It is one of the most widely used drugs in modern medicine, and is on the World Health Organization’s List of Essential Medicines. It has a variety of medical uses and is FDA-approved as an anesthetic.

Ketamine has a remarkably safe track record in surgical settings and is frequently used in pediatric surgery. The US military has used ketamine as a battlefield anesthetic since the Vietnam War.

Ketamine has been found to be effective in treating many conditions as a surgical anesthetic, and has only been approved by the FDA to be marketed as such. Ketamine’s use outside of that as an anesthetic is considered “off-label.” It is estimated that almost 1/4 of all prescription medications sold in the United States are prescribed off label. In the US, ketamine is listed as a DEA Schedule III drug.
