Lumigan vs Bimatoprost: are they the same?
Lumigan is a commercial brand whose active ingredient is exactly Bimatoprost. 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 — Lumigan contains Bimatoprost as its active ingredient. Talking about "Lumigan" in clinical terms is the same as talking about Bimatoprost at the dose strengths 0.01%, 0.03%. The differences from the authorised generic are brand, manufacturer (AbbVie / Allergan), excipients, tablet appearance and price — not the active molecule itself.
When Lumigan is used
Lumigan is approved in adults for the reduction of elevated intraocular pressure in patients with chronic open-angle glaucoma or ocular hypertension.
Mechanisms compared
Because they share the same active ingredient, the mechanism is identical: Bimatoprost is a prostamide analogue that increases aqueous humour outflow through both the trabecular meshwork and the uveoscleral pathway, lowering intraocular pressure.
Brand or generic — which to choose?
For most patients, authorised generics of Bimatoprost are clinically equivalent substitutes for Lumigan 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.
