Dorzolamide, sold under the brand name Trusopt among others, is a medication used to treat high pressure inside the eye, including in cases of glaucoma.[3] It is used as an eye drop.[3] Effects begin within three hours and last for at least eight hours.[3] It is also available as the combination dorzolamide/timolol.[3][4]

Common side effects include eye discomfort, eye redness, taste changes, and blurry vision.[3] Serious side effects include Steven Johnson syndrome.[3] Those allergic to sulfonamides may be allergic to dorzolamide.[3][5] Use is not recommended in pregnancy or breastfeeding.[5] It is a carbonic anhydrase inhibitor and works by decreasing the production of aqueous humor.[3]

Dorzolamide was approved for medical use in the United States in 1994.[3] It is available as a generic medication.[5] In 2022, it was the 201st most commonly prescribed medication in the United States, with more than 2 million prescriptions.[6][7]
