Neurontin vs Gabapentin: are they the same?
Neurontin is a commercial brand whose active ingredient is exactly Gabapentin. 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 — Neurontin contains Gabapentin as its active ingredient. Talking about "Neurontin" in clinical terms is the same as talking about Gabapentin at the dose strengths 100mg, 300mg, 400mg, 600mg, 800mg. The differences from the authorised generic are brand, manufacturer (Pfizer), excipients, tablet appearance and price — not the active molecule itself.
When Neurontin is used
Neurontin ist bei Erwachsenen und Kindern ab drei Jahren zur Zusatztherapie fokaler Anfälle und bei Erwachsenen zur Behandlung der postherpetischen Neuralgie zugelassen.
Mechanisms compared
Because they share the same active ingredient, the mechanism is identical: Gabapentin bindet an die Alpha-2-Delta-Hilfsuntereinheit spannungsabhängiger Calciumkanäle im zentralen Nervensystem und reduziert dadurch den präsynaptischen Calciumeinstrom sowie die Freisetzung exzitatorischer Neurotr…
Brand or generic — which to choose?
For most patients, authorised generics of Gabapentin are clinically equivalent substitutes for Neurontin 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.
