Rapid and sustained improvement in treatment-refractory depression through use of acute intravenous ketamine and concurrent transdermal selegiline: A case series.

BACKGROUND

Treatment resistant depression is a significant source of morbidity and mortality. For patients having failed or unable to undergo the electroconvulsive therapy procedure few effective alternative treatments exist.

METHODS

A case series is presented where six patients with treatment resistant depression failing both electroconvulsive therapy and oral antidepressants are concomitantly treated with short course intravenous ketamine and longer term selegiline transdermal system.

RESULTS

All six patients experienced clinical improvement with intravenous ketamine, with resolution of suicidality, increased food intake, and commitment to treatment adherence. Five patients showed sustained improvement with the selegiline transdermal system. One patient discontinued selegiline after developing peripheral edema and palpitations.

LIMITATIONS: This case series included only patients experiencing moderate to severe treatment resistant depression. Availability of long-term follow-up data not available in some cases.

CONCLUSION

Intravenous ketamine with simultaneous administration of the selegiline transdermal system is one strategy for treating treatment resistant depression in patients having failed or unable to undergo the electroconvulsive therapy procedure.
