In this This Is Why pharmacology review, Dr. Busti unpacks the Serotonin–Norepinephrine Reuptake Inhibitors (SNRI) — how they evolved as “cleaner, safer TCA-like” options and why they’re often the next step after SSRIs for major depressive disorder and anxiety disorders. Dr. Busti compares the class head-to-head and zooms into real-world decisions: when SNRIs shine (e.g., pain comorbidities), when to be cautious (e.g., hypertension, SIADH/hyponatremia, discontinuation syndrome), and how dose and kinetics shape outcomes (e.g., venlafaxine as SSRI at low dose, true SNRI at higher doses).
You’ll get crisp pearls on the key agents—duloxetine, venlafaxine, desvenlafaxine, milnacipran, levomilnacipran—including indications beyond MDD (GAD, panic/social anxiety, neuropathic pain, fibromyalgia, chronic MSK pain; regional use in stress urinary incontinence), common adverse effects, interaction traps (e.g., MAOI washouts, serotonergic stacking), and a practical monitoring & counseling checklist you can use tomorrow.
