Key takeaways
Bimatoprost (Lumigan) and latanoprostene bunod (Vyzulta) are both medications used to lower eye pressure in conditions like open-angle glaucoma and ocular hypertension. They belong to the same drug class, prostaglandins, and are used as eye drops once daily in the evening. However, they have some differences. Bimatoprost is available in both brand and generic forms, while latanoprostene bunod is only available as a brand-name medication. Bimatoprost is approved for people 16 years and older, whereas latanoprostene bunod is approved for those 17 and older. Bimatoprost can cause side effects like eye redness, itchy eyes, and eyelash growth, while latanoprostene bunod may cause eye redness and eye pain. Both medications can darken the color of your eyes and eyelashes over time. Additionally, latanoprostene bunod releases nitric oxide, which helps lower eye pressure through two pathways, unlike bimatoprost, which uses one pathway.
