OWHAT DORZOLAMIDE/TIMOLOL EYE DROPS IS AND WHAT IT IS USED FOR
Dorzolamide/Timolol contains two medicines: dorzolamide and timolol.
Dorzolamide belongs to a group of medicines called "carbonic anhydrase inhibitors"

Dorzolamide/Timolol is prescribed to lower raised pressure in the eye in the treatment of glaucoma when beta-blocker eye drop medicine used alone is not adequate.
