How does bimatoprost work?
Bimatoprost increases the drainage of fluid from the eye (aqueous humor), which lowers intraocular pressure and reduces the risk of optic nerve damage.
What is bimatoprost used to treat?
Bimatoprost is commonly prescribed for:
- Glaucoma (to prevent optic nerve damage caused by high eye pressure)
