While ketamine can be legally prescribed and administered “off label” by licensed physicians, the drug has only been officially approved by the FDA as an anesthetic and not as a treatment for depression. By way of comparison, an estimated 30% of all medications are prescribed “off-label,” including many cancer drugs, and are frequently used by physicians even though they are not FDA approved for that particular purpose. Although ketamine has shown the potential to help millions of people find relief from the crushing effects of depression and neuropathic pain, pharmaceutical companies have been hesitant to invest the tens of millions of dollars required to fund the extensive and expensive clinical trial process necessary to get official FDA approval. Since the drug is and will remain off-patent, no company can own the revenue stream. Ketamine’s use for depression and neuropathic pain treatment follows all required rules and regulations, and has safely and effectively been prescribed as a fast-acting depression and pain treatment for almost a decade in private medical practices and some hospitals and HMOs.
