Single infusion of controversial drug changed severe depression symptoms within hours, study finds
A recent study indicates that a single intravenous infusion of ketamine can rapidly alleviate symptoms of severe depression. The review analyzed 26 clinical trials involving over 1,100 patients, showing significant improvements in depressive symptoms within hours. While ketamine can be effective, it also carries risks of misuse and temporary side effects.
