Esketamine nasal spray: New hope for resistant depression

Esketamine nasal spray: New hope for resistant depression

On March 05, 2019 The U.S. Food and Drug Administration approved Spravato (esketamine) nasal spray, in conjunction with an oral antidepresant, for the treatment of depression in adults who have tried other antidepressant medicines but have not benefited from them (treatment-resistant depression).

Because of the risk of serious adverse outcomes resulting from sedation and dissociation caused by Spravato administration, and the potential for abuse and misuse of the drug, it is only available through a restricted distribution system, under a Risk Evaluation and Mitigation Strategy (REMS).

Non respondents depressives:

Patients with major depressive disorder who, despite trying at least two antidepressant treatments given at adequate doses for an adequate duration in the current episode, have not responded to treatment are considered to have treatment-resistant depression.

Spravato!

The Spravato labeling contains a Boxed Warning that cautions that patients are at risk for sedation and difficulty with attention, judgment and thinking (dissociation), abuse and misuse, and suicidal thoughts and behaviors after administration of the drug.

Because of the risk of sedation and dissociation, patients must be monitored by a health care provider for at least two hours after receiving their Spravato dose.

The REMS requires the prescriber and the patient to both sign a Patient Enrollment Form that clearly states that the patient understands they should make arrangements to safely leave the health care setting to get home and that the patient should not drive or use heavy machinery for the rest of the day on which they received the drug.

Additionally, Spravato must be dispensed with a patient Medication Guide that outlines the drug’s uses and risks.
