Side-effects associated with ketamine use in depression: a systematic review
This is the first systematic review of the safety of ketamine in the treatment of depression after single and repeated doses. We searched MEDLINE, PubMed, PsycINFO, and Cochrane Databases and identified 288 articles, 60 of which met the inclusion criteria. After acute dosing, psychiatric, psychotomimetic, cardiovascular, neurological, and other side-effects were more frequently reported after ketamine treatment than after placebo in patients with depresssion. Our findings suggest a selective reporting bias with limited assessment of long-term use and safety and after repeated dosing, despite these being reported in other patient groups exposed to ketamine (eg, those with chronic pain) and in recreational users. We recommend large-scale clinical trials that include multiple doses of ketamine and long-term follow up to assess the safety of long-term regular use.
En volgens mij bijbehorend comment, in ieder geval uit hetzelfde issue;
Can we confidently use ketamine as a clinical treatment for depression?
Findings from several proof-of-concept, double-blinded, placebo-controlled studies have shown rapid and large antidepressant effects in patients with major depression after a single dose of ketamine.1 These data are remarkable in the rapidity of therapeutic effects, with remission within 24 h (though relapse often occurs within days), the high degree of antidepressant potency in cohorts with moderate-to-high treatment resistance, and the consistency of findings between studies. Given that ketamine is readily available in many countries as an approved anaesthetic drug, it is not surprising that there has been enthusiasm for the use of ketamine to treat depression.
