Ketamine shows efficacy comparable to electroconvulsive therapy (ECT) for depression. Its low side-effect profile suggests evaluating ketamine as a second-line treatment for refractory depression.
Area of Science:
- Psychiatry
- Pharmacology
- Clinical Medicine
Background:
- Electroconvulsive therapy (ECT) is a highly effective treatment for depression.
- Ketamine demonstrates non-inferior efficacy to ECT for depression.
- Ketamine is currently considered a third-line option for treatment-refractory depression.
Purpose of the Study:
- To evaluate ketamine as a second-line augmentation strategy for refractory depression.
- To compare the efficacy and side-effect profile of ketamine with existing depression treatments.
Main Methods:
- Review of available data on ketamine's efficacy and tolerability.
- Comparison of ketamine's side-effect burden with second-line augmentation strategies.
- Consideration of treatment outcomes in relation to the duration of untreated illness.
Main Results:
- Ketamine is non-inferior to ECT in treating depression.
- Ketamine has a lower side-effect burden compared to many second-line depression treatments.
- Ketamine is better tolerated than several augmentation strategies.
Conclusions:
- Ketamine's high efficacy and low side-effect burden warrant its consideration as a second-line treatment.
- Re-evaluating ketamine's position from third-line to second-line agent is in patients' best interest.
- Further research should explore ketamine's role in optimizing depression treatment outcomes.

Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...
