Product Description:

Esketamine nasal spray is a novel antidepressant specifically indicated for treatment-resistant depression (TRD) in adults. It provides a rapid-acting option for patients with major depressive disorder (MDD) who have not responded adequately to conventional antidepressant therapies. Esketamine is the S-enantiomer of ketamine and acts as an NMDA receptor antagonist, modulating glutamatergic neurotransmission in the brain to improve mood and cognitive function.

Major depressive disorder is a widespread mental health condition affecting millions globally, characterized by persistent low mood, loss of interest or pleasure in daily activities, and associated symptoms such as fatigue, weight changes, psychomotor retardation, feelings of worthlessness, impaired concentration, and suicidal thoughts. Esketamine offers a valuable therapeutic approach for patients with severe or refractory depression, providing benefits in both symptom relief and functional improvement. Administered intranasally under medical supervision, it is generally well-tolerated, though monitoring for potential adverse effects, including dissociation and blood pressure changes, is recommended. Esketamine represents an important advancement in the management of MDD, particularly for patients with limited response to traditional antidepressants.
