Amitriptyline

A tricyclic antidepressant (tca) that affects chemicals in the brain linked to mood and emotions.

Ketamine Hydrochloride

An anesthetic with antidepressant properties, affecting glutamate neurotransmission.

Treatment-resistant depression (TRD): When other antidepressants have failed to provide adequate relief.

Suicidal ideation in severe depression: In cases where the risk of self-harm is high and other treatments haven't been effective.

Major Depressive Disorder (MDD) with severe symptoms: This combination may be considered for patients with acutely severe symptoms unresponsive to standard treatments.

Amitriptyline primarily blocks the reuptake of serotonin and norepinephrine, increasing their levels in the brain. Ketamine acts differently, blocking NMDA receptors, leading to rapid changes in synaptic plasticity and potentially faster antidepressant effects than TCAs alone. The combination aims to leverage the different mechanisms to improve treatment outcomes.

Store at room temperature, away from moisture, heat, and light. Keep out of reach of children. Discard according to healthcare professional's instructions.

Dosage is highly individualized and determined by a physician based on individual needs and response.

Ketamine is typically administered intravenously in a clinical setting under medical supervision, not usually combined in a single pill with amitriptyline.

Amitriptyline may be given orally in combination with a separate ketamine treatment plan.
