SSRI Antidepressants: Pharmacology Made Easy & Clinically Relevant

In this This Is Why pharmacology review, Dr. Busti walks through the Selective Serotonin Reuptake Inhibitors (SSRIs)—how they became first-line for major depressive disorder and a wide range of anxiety-related disorders, and where their real-world pitfalls live.

We compare the core agents—citalopram, escitalopram, fluoxetine, fluvoxamine, paroxetine, and sertraline—covering indications, mechanism, and clinical nuances that matter at the bedside. You’ll learn how dose, half-life, metabolism, and side-effect patterns influence patient-specific choices, and what to monitor for safety and success.

This episode includes practical guidance on:

• Managing sexual dysfunction, QT risk, and SIADH
• Recognizing CYP2D6 interactions
• Understanding fluoxetine’s long half-life
• Applying MAOI washout rules to avoid serotonin syndrome
• Starting low and titrating slow for anxiety

If you want to go beyond memorization and understand the why behind the what, this episode connects the science, safety, and strategy of SSRI use.
