Pharmacology

Esketamine (S-enantiomer of racemic ketamine) is a nonselective, noncompetitive N-methyl-D-aspartate (NMDA) receptor antagonist. The mechanism by which it exerts its antidepressant effect is unknown. The major circulating metabolite noresketamine demonstrated activity at the same receptor with less affinity.

Distribution

V_d: 709 L

Metabolism

Primarily metabolized to the active metabolite noresketamine via cytochrome P450 (CYP) enzymes CYP2B6 and CYP3A4 and to a lesser extent CYP2C9 and CYP2C19. Noresketamine is metabolized via CYP-dependent pathways and certain subsequent metabolites undergo glucuronidation.

Excretion

Urine (<1% as unchanged drug)

Time to Peak

Plasma: 20 to 40 minutes

Half-Life Elimination

Esketamine: 7 to 12 hours; Noresketamine (active metabolite): ~8 hours

Protein Binding

~43% to 45%

Special Populations: Hepatic Function Impairment

Mean esketamine AUC and t_1/2 values were higher in patients with moderate hepatic impairment.

Special Populations: Elderly

Mean esketamine C_max and AUC values were higher in elderly patients compared with younger adult patients.

Use: Labeled Indications

Depression, treatment-resistant: Treatment of treatment-resistant depression in adults, in conjunction with an oral antidepressant.

Major depressive disorder (unipolar) with suicidality: Treatment of depressive symptoms in adults with major depressive disorder with suicidal ideation or behavior.

Limitations of use: Not approved as an anesthetic agent. The safety and effectiveness of esketamine as an anesthetic agent have not been established. Additionally, esketamine treats depressive symptoms; effectiveness of esketamine in preventing suicide or decreasing suicidal ideation has not been shown.

Contraindications

Hypersensitivity to esketamine, ketamine, or any component of the formulation; aneurysmal vascular disease (including thoracic and abdominal aorta, intracranial, and peripheral arterial vessels) or arteriovenous malformation; history of intracerebral hemorrhage.

Canadian labeling: Additional contraindications (not in US labeling): Recent (within 6 weeks) major cardiovascular event (such as myocardial infarction or cerebrovascular accident).

Dosing: Adult

Note: Administer in conjunction with an oral antidepressant. Must be administered under the direct supervision of a health care provider with patients monitored for adverse effects for at least 2 hours following administration.

Depression, treatment-resistant: Intranasal:

Induction: 56 mg twice weekly; may increase dose (after first dose) based on response and tolerability to 84 mg twice weekly. After 4 weeks, evaluate for evidence of therapeutic benefit to determine need for continued treatment.

Maintenance: Beginning on week 5, using the previously established dose (56 or 84 mg) decrease the dosing frequency to once weekly. At week 9 and onward, continue effective dose (56 or 84 mg) once weekly or decrease to every 2 weeks.

Major depressive disorder (unipolar), with suicidality: Intranasal: Initial: 84 mg twice weekly for 4 weeks; may reduce dosage to 56 mg twice weekly based on tolerability. After 4 weeks, evaluate for evidence of therapeutic benefit to determine need for continued treatment; use beyond 4 weeks has not been evaluated.

Missed treatment sessions:

Treatment-resistant depression:

Missed treatment sessions and no worsening of symptoms: Continue current dosing schedule.

Missed treatment sessions during maintenance treatment and worsening of symptoms: Consider returning to patient's previous dosing schedule (eg, every 2 weeks to once weekly or weekly to twice weekly).

Major depressive disorder (unipolar) with suicidality:

Missed treatment sessions and no worsening of symptoms: Continue current dosing schedule.

Dosing: Geriatric

Refer to adult dosing.

Administration

Intranasal: To reduce risk of nausea and vomiting, avoid food for at least 2 hours before administration and avoid drinking liquids at least 30 minutes prior to administration. If patient requires a nasal corticosteroid or nasal decongestant on a dosing day, administer at least 1 hour prior to administration of esketamine. Do not prime the device prior to use to avoid medication loss; device indicator will show 2 green dots indicating ready for use (get a new device if dots are not present). Each nasal spray device contains 2 sprays (1 spray for each nostril) and delivers a total of 28 mg; spray once into each nostril per device. Use 2 devices for 56 mg dose or 3 devices for 84 mg dose, with a 5-minute rest between use of each device to allow for absorption. Gently blow nose to clear nostrils before the first device only. Instruct patient to recline head about 45 degrees. Instruct patient to close opposite nostril and breathe in through the nose while pushing plunger all way up the nose until it stops. Instruct patient to sniff gently after spraying into the nose. Dab any excess liquid with a tissue; do not blow nose. Dispose of used devices according to procedure for a schedule III drug and according to federal, state, and local regulations.

Warnings/Precautions

Concerns related to adverse effects:

• Abuse and misuse: [US Boxed Warning]: Esketamine has the potential to be abused and misused. Consider the risks and benefits of prescribing esketamine prior to use in patients at higher risk of abuse. Monitor patients for signs and symptoms of abuse and misuse including drug-seeking behavior, while on therapy. Individuals with a history of drug abuse or dependence are at greater risk; use careful consideration prior to treatment and monitor for signs of abuse or dependence.

• CNS depression: [US Boxed Warning]: Patients are at risk for sedation after administration of esketamine. Because of the risks of sedation, patients must be monitored for at least 2 hours at each treatment session, followed by an assessment to determine when the patient is considered clinically stable and ready to leave the health care setting. CNS depression may impair physical or mental abilities; patients must be cautioned about performing tasks that require mental alertness (eg, operating machinery or driving) until the next day after a restful sleep. Manufacturer labeling recommends patients arrange transportation home following treatment. No adverse effects of esketamine nasal spray on cognitive functioning were observed in a one-year open-label safety study; long-term cognitive and memory impairment have been reported with repeated ketamine misuse or abuse. Closely monitor sedation with concomitant CNS depressants.

• Dissociation: [US Boxed Warning]: Patients are at risk for dissociative or perceptual changes after administration of esketamine. Because of the risks of dissociation, patients must be monitored for at least 2 hours at each treatment session, followed by an assessment to determine when the patient is considered clinically stable and ready to leave the health care setting. Given its potential to induce dissociative or perceptual changes (including distortion of time, space, and illusions), derealization and depersonalization, assess patients with psychosis carefully before esketamine administration; treatment should only be initiated if benefit outweighs risk.

• Blood pressure: Increases in systolic and/or diastolic BP (occurring ~40 minutes after administration and lasting ~4 hours) have been observed at all recommended doses. Substantial BP increases may occur after any dose even if smaller effects were observed with previous administrations. Esketamine is contraindicated in patients for whom an increase in BP or intracranial pressure poses a serious risk (eg, aneurysmal vascular disease, arteriovenous malformation, history of intracerebral hemorrhage). Carefully assess patients with other cardiovascular and cerebrovascular conditions prior to esketamine use to determine whether the potential benefits outweigh the risks. Assess BP prior to administration; if elevated (>140/90 mm Hg) consider the benefits and risks of delaying therapy. Measure BP ~40 minutes post-dose and subsequently as clinically indicated for at least 2 hours after administration of last dose or until values decline. Refer patients experiencing symptoms of a hypertensive crisis (eg, chest pain, shortness of breath) or hypertensive encephalopathy (eg, sudden severe headache, visual disturbance, seizures, diminished consciousness or focal neurological deficits) immediately for emergency care. Closely monitor blood pressure with concomitant use of esketamine with psychostimulants or monoamine oxidase inhibitors. In patients with a history of hypertensive encephalopathy, more intensive monitoring, including more frequent BP and symptom assessment is warranted because these patients are at increased risk for developing encephalopathy with even small increases in BP.

• Suicidal thoughts and behaviors: [US Boxed Warning]: Antidepressants increased the risk of suicidal thoughts and behavior in pediatric and young adult patients in short-term studies. Short-term studies did not show an increased risk in patients >24 years of age and showed a decreased risk in patients ≥65 years. Closely monitor all patients for clinical worsening, suicidality, or unusual changes in behavior, particularly during the initial 1 to 2 months of therapy or during periods of dosage adjustments (increases or decreases); the patient's family or caregiver should be instructed to closely observe the patient and communicate condition with health care provider. The possibility of a suicide attempt is inherent in major depression and may persist until remission occurs. Worsening depression and severe abrupt suicidality that are not part of the presenting symptoms may require discontinuation or modification of drug therapy. Esketamine is not approved in pediatric patients.

• Ulcerative or interstitial cystitis: Cases of ulcerative or interstitial cystitis have been reported in individuals with long-term off-label use or misuse/abuse of ketamine. In clinical trials there was a higher rate of lower urinary tract symptoms (pollakiuria, dysuria, micturition urgency, nocturia, and cystitis) in esketamine-treated patients; however, no cases of esketamine-related interstitial cystitis were observed in patients treated for up to a year. Monitor for urinary tract and bladder symptoms during the course of treatment and refer to an appropriate health care provider as clinically indicated.

Disease-related concerns:

• Hepatic impairment: Patients with moderate hepatic impairment may need to be monitored for adverse reactions for a longer period of time. Esketamine is not recommended in patients with severe hepatic impairment.

Concurrent drug therapy issues:

• Drug interactions: Potentially significant interactions may exist, requiring dose or frequency adjustment, additional monitoring, and/or selection of alternative therapy. Consult drug interactions database for more detailed information.

Other warnings/precautions:

• Appropriate use: Use of esketamine does not preclude the need for hospitalization if clinically needed, even if improvement is seen after initial dose. Additionally, esketamine treats depressive symptoms; the safety and effectiveness of esketamine in the prevention of suicide or reducing suicidal ideation or behavior has not been established.

• REMS program: [US Boxed Warning]: Because of the risks of serious adverse outcomes resulting from sedation, dissociation, and abuse and misuse, esketamine is only available through a restricted program under a Risk Evaluation and Mitigation Strategy (REMS) called the SPRAVATO REMS. Under the esketamine REMS program, only certified health care settings and pharmacies may administer and dispense esketamine. Esketamine may only be administered to patients who are enrolled in the program and under the direct observation of a health care provider (during administration) with monitoring for at least 2 hours following the last dose. Call 855-382-6022 or visit www.spravatorems.com for further information.

Monitoring Parameters

Monitor all patients for adverse effects in a health care setting for at least 2 hours following administration of the last dose.

Blood pressure (prior to dose; repeat ~40 minutes post-dose, and then as clinically indicated for at least 2 hours post-dose); suicidal ideation (especially at the beginning of therapy or when doses are increased or decreased)

Prior to administration, assess patient risk for abuse or misuse, psychosis, and cardiovascular and cerebrovascular conditions.

Closely monitor all patients for clinical worsening of depression and emergence of suicidal thoughts and behaviors, especially during the initial few months of therapy and at times of dosage changes; assess for evidence of therapeutic benefit at the end of the induction phase to determine need for continued treatment; closely monitor patients for signs/symptoms of abuse and misuse during therapy; monitor for sedation with use of concomitant CNS depressants; monitor for urinary tract or bladder symptoms during the course of treatment.

Reproductive Considerations

Based on adverse events observed in animal reproduction studies, the manufacturer recommends females of reproductive potential consider pregnancy planning and prevention during esketamine therapy.

Pregnancy Considerations

Based on animal data, use of medications that block N-methyl-D-aspartate (NMDA) receptors and/or potentiate gamma-aminobutyric acid (GABA) activity, may affect brain development.

The ACOG recommends treatment of depression during pregnancy should be individualized and incorporate the clinical expertise of the mental health clinician, obstetrician, primary health care provider, and pediatrician. According to the American Psychiatric Association (APA), the risks of medication treatment should be weighed against other treatment options and untreated depression. For women who discontinue antidepressant medications during pregnancy and who may be at high risk for postpartum depression, the medications can be restarted following delivery. Treatment algorithms have been developed by the ACOG and the APA for the management of depression in women prior to conception and during pregnancy (ACOG 2008; APA 2010; Yonkers 2009)

Pregnant females exposed to antidepressants during pregnancy are encouraged to enroll in the National Pregnancy Registry for Antidepressants (NPRAD). Females 18 to 45 years of age or their health care providers may contact the registry by calling 1-844-405-6185 or online at https://womensmentalhealth.org/clinical-and-researchprograms/ pregnancyregistry/antidepressants/. Enrollment should be done as early in pregnancy as possible.
