Ketamine is a well-established anesthetic used worldwide since 1970 and is listed on the World Health Organization's Essential Medicines list. Over the years, it has been shown to be highly effective in treating conditions like treatment-resistant depression, PTSD, anxiety, suicidal thoughts, and neuropathic pain. Unlike traditional antidepressants, which may take weeks to show results, ketamine often shows improvement after just one intravenous (IV) dose. This makes it especially valuable for providing immediate relief from mood disorders and suicidal ideation.
