Ketamine infusions can help reduce symptoms of suicidal ideation, depression, and anxiety in patients with treatment-resistant depression, new research suggests.
in hospitals, ketamine is also taken illegally as a recreational drug. Users may aim for an intense high or feeling of dissociation, or an out-of-body–type experience.
Patients in the study were typically started on 0.5 mg/kg of ketamine, with the dose titrated to achieve symptoms of partial dissociation. The median dose administered after titration was 0.93 mg/kg over 40 minutes. The primary outcome was PHQ-9 total scores, for which researchers looked at seven time periods: 1 week, 2-3 weeks, 4-6 weeks, 7-12 weeks, 13-24 weeks, 25-51 weeks, and 52+ weeks.Results showed PHQ-9 total scores declined by 50% throughout the course of treatment, with much of the improvement gained within 4-6 weeks. There was a significant difference between week 1 and all later time periods and between weeks 2 and 3 and all later periods .
Oliver noted that the success rate for repetitive transcranial magnetic stimulation is 40%-60% depending on the modality; and for selective serotonin reuptake inhibitors, the success rate"is somewhere between the mid-20s and low-30s percent range." Symptoms of generalized anxiety were also substantially improved. There was about a 30% reduction in the GAD-7 score during treatment and, again, most of the response occurred by 4-6 weeks.Sex, age, and other demographic characteristics did not predict response or remission, but suicide planning trended toward higher response rates . This suggests that a more depressed subgroup can achieve greater benefit from the treatment than can less symptomatic patients, the investigators note.
Previous research has suggested that ketamine therapy is not linked to long-term side effects, such as sexual dysfunction, weight gain, lethargy, or cognitive issues, said Oliver.
