Zoloft vs Sertraline: are they the same?
Zoloft is a commercial brand whose active ingredient is exactly Sertraline. This page explains what that means in practice: where they differ (brand, manufacturer, price, available strengths), why they are clinically equivalent, and when the brand or an authorised generic is the better choice.
Are they the same?
Yes — Zoloft contains Sertraline as its active ingredient. Talking about "Zoloft" in clinical terms is the same as talking about Sertraline at the dose strengths 25mg, 50mg, 100mg. The differences from the authorised generic are brand, manufacturer (Pfizer), excipients, tablet appearance and price — not the active molecule itself.
When Zoloft is used
Zoloft est autorisé chez l'adulte dans la dépression caractérisée, le trouble panique avec ou sans agoraphobie, le trouble obsessionnel compulsif, l'état de stress post-traumatique, l'anxiété sociale et le trouble dysphorique prémenstruel.
Mechanisms compared
Because they share the same active ingredient, the mechanism is identical: La sertraline agit en bloquant sélectivement le transporteur de la sérotonine, empêchant la recapture de la sérotonine depuis la fente synaptique et augmentant sa concentration synaptique.
Brand or generic — which to choose?
For most patients, authorised generics of Sertraline are clinically equivalent substitutes for Zoloft and typically cost substantially less. The practical differences are manufacturer, excipients (rarely matters except in specific sensitivities), tablet appearance and price. The brand is preferred by some patients for personal reasons or insurance coverage; the generic is the default when cost matters.
