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.

Gadofosveset is a contrast agent. It is used in magnetic resonance angiography (MRA) to help create a clear picture of the blood vessels (arteries). The MRA scan is a special kind of diagnostic procedure. It uses magnets and computers to create images or “pictures” of the blood vessels in certain areas of the body. Gadofosveset is a gadolinium-based contrast agent (GBCA).

Gadofosveset is given by injection before MRA to help diagnose problems in the blood vessels (e.g., blockage of the arteries).

Gadofosveset is to be used only by or under the direct supervision of a doctor.
