Used intranasally for treatment (in combination with an oral antidepressant) of treatment-resistant depression. Although there are various definitions of treatment-resistant depression, the condition is often defined as the failure of ≥2 trials of first-line antidepressants given in an adequate dosage for an adequate duration of therapy.

Intranasal esketamine substantially improved depressive symptoms as measured by the Montgomery-Asberg Depression Rating Scale (MADRS) within 24 hours of administration in a short-term clinical trial and prolonged time to relapse in a longer-term maintenance trial.

Esketamine is the S-enantiomer of racemic ketamine, which is an anesthetic agent. However, esketamine is not labeled for use as an anesthetic agent; efficacy and safety not established.

With the advent of more effective therapies for the treatment of peptic ulcer disease, antimuscarinics have only limited usefulness in this condition.
