What Is Spravato?

Spravato (esketamine) Nasal Spray is a non-competitive N-methyl D-aspartate (NMDA) receptor antagonist indicated, in conjunction with an oral antidepressant, for the treatment of treatment-resistant depression (TRD) in adults.

What Are Side Effects of Spravato?

Common side effects of Spravato include:

Dosage for Spravato

The day 1 starting dose of Spravato is 56 mg. Subsequent doses of of Spravato are 56 mg or 84 mg administered twice a week for weeks 1 to 4, once weekly weeks 5 to 8, and every 2 weeks or once weekly week 9 and after.

What Drugs, Substances, or Supplements Interact with Spravato?

Spravato may interact with CNS depressants (e.g., benzodiazepines, opioids, alcohol), psychostimulants (e.g., amphetamines, methylphenidate, modafanil, armodafinil), and monoamine oxidase inhibitors (MAOIs). Tell your doctor all medications and supplements you use.

Spravato During Pregnancy and Breastfeeding

Tell your doctor if you are pregnant or plan to become pregnant before using Spravato; it may harm a fetus. There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to antidepressants, including Spravato, during pregnancy. Spravato passes into breast milk. Because of the potential for neurotoxicity, breastfeeding is not recommended while using Spravato. Withdrawal symptoms may occur if you suddenly stop taking Spravato.

Get emergency medical help if you have signs of an allergic reaction: hives; difficult breathing; swelling of your face, lips, tongue, or throat.

Your blood pressure will need to be checked before and after you use esketamine. Esketamine can increase your blood pressure for several hours after each dose. Tell your doctor if you have chest pain, trouble breathing, severe headache, blurred vision, pounding in your neck or ears, or a seizure.

Also call your doctor at once if you have:

  • extreme drowsiness or feeling like you might pass out;
  • severe dizziness or feelings of floating;
  • unusual changes in mood or behavior;
  • thoughts of hurting yourself;
  • worsening depression;
  • sleep problems;
  • problems with thinking or memory;
  • unusual or unpleasant memories (flashbacks);
  • hallucinations, feeling "spaced out"; or
  • urination problems (painful urination, increased urination, urgent need to urinate).

Common side effects may include:

  • dissociation, feeling drunk;
  • increased blood pressure;
  • drowsiness;
  • dizziness, spinning sensation;
  • feeling anxious;
  • nausea, vomiting; or
  • decreased sensations (touch or other senses).

Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice.

Patient Exposure

SPRAVATO was evaluated for safety in 1709 patients diagnosed with treatment resistant depression (TRD) [see Clinical Studies] from five Phase 3 studies (3 short-term and 2 long-term studies) and one Phase 2 dose-ranging study. Of all SPRAVATO-treated patients in the completed Phase 3 studies, 479 (30%) received at least 6 months of treatment, and 178 (11%) received at least 12 months of treatment.

Adverse Reactions Leading To Discontinuation Of Treatment

In short-term studies in adults < 65 years old (Study 1 pooled with another 4-week study), the proportion of patients who discontinued treatment because of an adverse reaction was 4.6% in patients who received SPRAVATO plus oral AD compared to 1.4% for patients who received placebo nasal spray plus oral AD. For adults ≥ 65 years old, the proportions were 5.6% and 3.1%, respectively. In Study 2, a long-term maintenance study, the discontinuation rates because of an adverse reaction were similar for patients receiving SPRAVATO plus oral AD and placebo nasal spray plus oral AD in the maintenance phase, at 2.6% and 2.1%, respectively. Across all Phase 3 studies, adverse reactions leading to SPRAVATO discontinuation in more than 2 patients were (in order of frequency): anxiety (1.2%), depression (0.9%), blood pressure increased (0.6%), dizziness (0.6%), suicidal ideation (0.5%), dissociation (0.4%), nausea (0.4%), vomiting (0.4%), headache (0.3%), muscular weakness (0.3%), vertigo (0.2%), hypertension (0.2%), panic attack (0.2%) and sedation (0.2%).

Most Common Adverse Reactions

The most commonly observed adverse reactions in TRD patients treated with SPRAVATO plus oral AD (incidence ≥5% and at least twice that of placebo nasal spray plus oral AD) were dissociation, dizziness, nausea, sedation, vertigo, hypoesthesia, anxiety, lethargy, blood pressure increased, vomiting, and feeling drunk. Table 3 shows the incidence of adverse reactions that occurred in TRD patients treated with SPRAVATO plus oral AD at any dose and greater than patients treated with placebo nasal spray plus oral AD.

Sedation

Sedation was evaluated by adverse event reports and using the Modified Observer's Alertness/Sedation scale (MOAA/s). In the MOAA/s scale, 5 means “responds readily to name spoken in normal tone” and 0 means “no response after painful trapezius squeeze.” Any decrease in MOAA/s from pre-dose is considered to indicate presence of sedation, and such a decrease occurred in a higher number of patients on esketamine than placebo during the short-term trials (Table 4). Dose-related increases in the incidence of sedation were observed in a fixed-dose study [see WARNINGS AND PRECAUTIONS].

Dissociation/Perceptual Changes

SPRAVATO can cause dissociative symptoms (including derealization and depersonalization) and perceptual changes (including distortion of time and space, and illusions). In clinical trials, dissociation was transient and occurred on the day of dosing. Dissociation was evaluated by adverse event reports and the Clinician-Administered Dissociative States Scale (CADSS) questionnaire. A CADSS total score of more than 4 indicates presence of dissociative symptoms, and such an increase to a score of 4 or more occurred in a higher number of patients on esketamine compared to placebo during the short-term trials (see Table 5). Dose-related increases in the incidence of dissociative symptoms (CADSS total score >4) were observed in a fixed-dose study. Table 5 shows the incidence of dissociation (CADSS total score >4) in a double-blind, randomized, placebo-controlled, fixed-dose study in adults <65 years of age and a double-blind, randomized, placebo-controlled, flexible-dose study with patients ≥ 65 years of age.

Increase In Blood Pressure

The mean placebo-adjusted increases in systolic and diastolic blood pressure (SBP and DBP) over time were about 7 to 9 mmHg in SBP and 4 to 6 mmHg in DBP at 40 minutes post-dose and 2 to 5 mmHg in SBP and 1 to 3 mmHg in DBP at 1.5 hours post-dose in patients receiving SPRAVATO plus oral antidepressants (Table 6).

Nausea And Vomiting

SPRAVATO can cause nausea and vomiting (Table 7). Most of these events occurred on the day of dosing and resolved the same day, with the median duration not exceeding 1 hour in most subjects across dosing sessions. Rates of reported nausea and vomiting decreased over time across dosing sessions from the first week of treatment in the short-term studies, as well as over time with long-term treatment (Table 7).

Sense Of Smell

Sense of smell was assessed over time; no difference was observed between patients treated with SPRAVATO plus oral AD and those treated with placebo nasal spray plus oral AD during the double-blind maintenance phase of Study 2 [see Clinical Studies].
