Ketamine Therapy
Spravato represents a revolutionary treatment approach for resistant depression by enabling quick therapeutic effects that become visible much sooner after nasal administration to adults than with traditional antidepressants. The nasal formulation delivers esketamine, gaining access to the central nervous system through a metered-dose device that blocks the NMDA receptor to activate synaptogenesis and elevate mood.
Spravato is only available through a REMS-certified program required by the FDA to ensure safety. This program requires experienced staff to assess vital signs and mental status while monitoring potential side effects of dissociation, sedation, and temporary blood pressure increases.
Studies also demonstrate the therapeutic advantages of using ketamine off-label for managing both neuropathic and chronic pain, while its primary purpose remains in psychiatric treatment. For psychiatric treatment, patients typically need to start with twice-weekly doses until healthcare providers make management decisions that combine treatment results with safety and tolerability aspects.
The dissociative anesthetic substance Ketamine received its first medical approval in the 1960s. In 2019, Spravato brand nasal spray delivered the S-enantiomer (esketamine) through a product from Janssen Labels called a precision metered-dose device in the United States markets. Esketamine's antidepressant function derives from its capability to modulate glutamate activity by blocking NMDA receptors, resulting in synaptogenic effects that define its quick action.
Nasally administered esketamine works as a treatment option for adult patients having major depressive disorder after failing two distinct antidepressant therapies, while also treating adults with depression and acute suicidal behaviors. The pharmaceutical administration of esketamine takes place only in medical facilities under direct supervision because of its dissociative effects and psychoactive properties.
The main effects of Esketamine function by blocking N-methyl-D-aspartate (NMDA) receptors, which belong to glutamate receptors throughout the central nervous system. The blocking effect of NMDA receptors activates glutamate release in spikes and activates AMPA receptors to drive synaptogenesis, which leads to improved neural connectivity with mood-enhancing results.
The analgesic effects of ketamine alongside its adjacent stereoisomer derivatives apply to neuropathic pain and chronic conditions because they modulate central sensitization and lower nociceptive responses. The administration of Ketamine nasal spray for pain management requires dosages that are either low or comparable to standard patient requirements because healthcare professionals are creating official treatment recommendations.
According to Janssen, treatment typically begins with twice-weekly doses for four weeks, followed by weekly or biweekly maintenance depending on response and tolerability. A single device contains 28 mg of medication, so the administration requires two devices for 56 mg and three for 84 mg.
Patients self-administer the nasal spray under the supervision of trained healthcare staff in a REMS-certified setting. An entire administration session includes 1.5 to 2 hours for medication delivery and recovery while providers monitor patient status during the period. Two hours of continuous monitoring follow the dosage to identify adverse effects, including sedation, dissociation, or high blood pressure.
Patients experience psychoactive effects from esketamine beginning 10 to 20 minutes after use, with maximum intensity reached in 20 to 40 minutes, lasting between 60 and 90 minutes.
Esketamine develops its active effects through the nasal route 10 to 20 minutes after administration and reaches its peak effects at 20 to 40 minutes following dose time for approximately 60 to 90 minutes. Per REMS guidelines, patients should not drive or operate heavy machinery until the day after treatment.
The dissociative and sedative acute effects usually disappear within hours, but patients might encounter smaller sedation levels together with perception alterations during the first five hours after taking the drug. The pivotal trials conducted showed no cases of respiratory depression, yet healthcare providers keep patients under respiratory monitoring as a routine safety measure.
The question arises, “How long does ketamine nasal spray last?” The simple answer is that, according to clinical research and medical practice reports, Esketamine nasal spray's antidepressant impact extends from 5 to 7 days. However, patient responses also depend on depression severity, metabolism, and medication dosage. Research on a specified patient group demonstrated positive therapeutic effects against placebo, which appeared within two to four hours of the intervention period and continued until day 28.
Relapse prevention for depression patients occurs through extended maintenance therapy exceeding six months, which produces long-term effectiveness while keeping patients in treatment remission for two years or longer using regular dosing protocols as reported by PMC. Relapse can occur as early as 7 to 10 days after stopping treatment.
Medical researchers use ketamine nasal spray to investigate its potential for treating neuropathic pain and pain from ongoing cancer. Still, the US Food and Drug Administration has not approved these applications. Studies on nasal ketamine use (10–30 mg per nostril, for example) demonstrate short-term benefits, but the results only lasted for several hours to multiple days after administration.
The blocking activity of ketamine on NMDA receptors helps decrease chronic pain disorders that stem from central sensitization and “wind-up” processes. Studies with substantial patient numbers need to be established to validate ketamine treatment effectiveness, while health providers specialized in pain management should lead off-label cases because of their knowledge regarding ketamine's dissociative properties and its impact on blood circulation. Some of the benefits and side effects of this treatment are as follows:
Many patients report dramatic mood transformation together with swift elimination of suicidal thoughts, which they describe as a “life-saving” approach for treating persistent severe depression. Many patients mention in-clinic administration of medication and potential adverse effects, and high costs as major issues when reviewing ketamine treatments online and in internet forums.
Mental health clinics showed that their patients were satisfied with the effectiveness of the treatment, yet patients assigned low scores to affordability issues and convenience concerns, thus highlighting the need to find an equilibrium between medical outcomes, logistical aspects, and financial implications.
The introduction of Ketamine nasal spray (esketamine) brings revolutionary changes to the treatment of depression patients with depression who do not respond to other forms of therapy, while potentially providing additional pain relief benefits. Its fast mechanism of action, together with lengthy symptom relief spanning one week after administration, enables healthcare providers to treat patients who have no response to regular treatments.
Careful patient discrimination, active medical supervision, and support services are needed to address the costs, dissociative side effects, and medical administration requirements. Ongoing research efforts seek to improve long-term safety outcomes while discovering more pain treatment uses for ketamine nasal spray, which exists as a promising therapeutic agent, although it presents complex management requirements.

FAQs
What does ketamine nasal spray feel like
Ketamine nasal spray triggers a dissociative state that causes detachment through dream-like feelings, together with mild euphoria, dizziness, or altered perceptions. The onset of mental and physical changes from this drug occurs within 10 to 20 minutes, while they usually last for sixty to ninety minutes.
What is ketamine nasal spray used for?
The primary purpose of Ketamine in nose spray form remains the treatment of depression that resists various therapies, as well as immediate suicidal thoughts. Medical professionals are investigating the off-label use of ketamine nasal spray for treating chronic pain because of its pain-relieving properties.
How long does ketamine last for sedation?
When used for sedation, ketamine effects remain active from 30 to 60 minutes, although duration depends on the administration route and dosage amount. Patients may experience minor sedation together with residual drowsiness following the dosage period.
