A combination of the plant-derived compound ibogaine with magnesium, given alongside complementary treatments, led to large improvements in functioning, PTSD, depression, and anxiety in 30 male Special Operations Forces veterans with mild traumatic brain injury. Functioning improved significantly both immediately after treatment and one month later, with very large effects on PTSD, depression, and anxiety at one month. No serious adverse events occurred. The authors call for controlled trials to confirm these initial open-label findings.
Ketamine rapidly reduces suicidal thoughts in major depressive disorder, but the effect is short-lived. In this trial, adults with major depression and active suicidal ideation received a single ketamine infusion, then were randomly assigned to take either low-dose buprenorphine or a placebo daily for four weeks. Suicidal thoughts dropped significantly more in the buprenorphine group (average decrease of 11.6 points on the Scale for Suicide Ideation) than in the placebo group (average decrease of 6.3 points). Depression scores did not differ between groups. No serious side effects occurred. Buprenorphine appears to sustain and boost ketamine's antisuicidal effects, offering a potentially safe, scalable option for suicide prevention.
