Severe depression

This novel approach offers a potential alternative to traditional antidepressants, which often take weeks to show effects – a luxury many palliative care patients don’t have.

Understanding Ketamine: Mechanism of Action

NMDA Receptor Antagonism

Ketamine primarily blocks the brain’s N-methyl-D-aspartate (NMDA) receptors. This mechanism:

Reduces glutamate signaling.
Alters neural connectivity.
Promotes neuroplasticity.

These effects contribute to ketamine’s unique ability to alleviate depressive symptoms and emotional distress rapidly.

Rapid-Acting Antidepressant Effects

Unlike conventional antidepressants, ketamine can produce noticeable improvements in mood within hours or days. This rapid action is precious in palliative care, where time is often limited. The quick onset of effects can:

Provide immediate relief from emotional suffering.
Improve the quality of life in a short timeframe.
Allow patients to engage more fully with loved ones and care providers.

Oral Ketamine vs. Traditional Ketamine Administration

Advantages of Oral Formulation

Oral ketamine offers several benefits over traditional intravenous (IV) administration:
