Bimatoprost, sold under the brand name Lumigan among others, is a medication used to treat high pressure inside the eye including glaucoma. Specifically it is used for open angle glaucoma when other agents are not sufficient. It may also be used to increase the size of the eyelashes. It is used as an eye drop and effects generally occur within four hours.Common side effects include red eyes, dry eyes, change in color of the eyes, blurry vision, and cataracts. Use during pregnancy or breastfeeding is generally not recommended. It is a prostaglandin analog and works by increasing the outflow of aqueous fluid from the eyes.Bimatoprost was approved for medical use in the United States in 2001. It is available as a generic medication. In 2018, it was the 274th most commonly prescribed medication in the United States, with more than 2 million prescriptions. Uses
Medical
Bimatoprost is used for the treatment of open-angle glaucoma and ocular hypertension in adults, either alone or in combination with a beta blocker, typically timolol.Studies have shown bimatoprost to be more effective than timolol in reduction of intraocular pressure (IOP) and at least as effective as the prostaglandin analogs latanoprost and travoprost in reducing IOP. Cosmetic
Bimatoprost may be used to treat small or underdeveloped eyelashes. The medical term for this is treatment of hypotrichosis; however, the U.S. Food and Drug Administration (FDA) approval is for purely cosmetic purposes (see Prostaglandin F receptor#Clinical significance). Side effects
Side effects are similar to other prostaglandin analogs applied to the eye.
