Are all SSRIs basically the same? The answer starts with "yes" and immediately turns into "except in every way that matters clinically." This episode breaks down the real differences between Prozac, Lexapro, paroxetine, fluvoxamine, sertraline, and the newer wave of antidepressants. We explore why escitalopram is the "purest" serotonin player, why paroxetine behaves like pharmacological buckshot, and how fluvoxamine's unique sigma-one agonism made it a candidate for OCD and even COVID research. Then we look at where drug development is heading — from vortioxetine's multi-receptor steering to Auvelity's bold break from serotonin altogether. If you've ever wondered whether your SSRI is actually different from someone else's, this episode explains the pharmacology, the clinical reasoning, and the future of the category.
