Antidepressant Tachyphylaxis: Systematic Approach to Antidepressant Failure

Evidence-Based Clinical Masterclass
Antidepressant Tachyphylaxis
A systematic approach to antidepressant failure. When a medication that once provided stability begins to fail, this text-based masterclass moves beyond reflexive dose escalation toward a 2026 precision-psychiatry framework — from receptor downregulation to the SAINT protocol and esmethadone.

About This Course

Antidepressant tachyphylaxis is a distinct subtype of relapse: a patient who previously achieved a stable therapeutic response (≥50% improvement) for at least six months experiences a gradual return of symptoms — despite staying on the same medication and dose. The reflexive response is usually dose escalation or trial-and-error.

This course replaces that reflex with a systematic framework — the Tachyphylaxis Clinical Audit — to diagnose why a treatment has failed and how to strategically respond. It spans the molecular dynamics of receptor downregulation through to current pharmacological, NMDA, and neuromodulation options, built for the busy clinician who needs actionable, peer-reviewed answers.

Format note: This is a text-based course. There are no video lectures — each chapter is written to be read and referenced like a professional clinical textbook.
