TROPICAMIDE (OPHTHALMIC)

Indications/Pharmacology Tropicamide, like atropine, causes mydriasis and cycloplegia, but has more mydriatic than cycloplegic activity. Tropicamide has a more rapid onset (maximum mydriasis in 15-30 minutes) of action and a shorter duration of action (pupil returns to normal in 6-12 hours in most... ↪ Read more

METIPRANOLOL (OPHTHALMIC)

Indications / Pharmacology Metipranolol HCl can be used as a substitute for timolol maleate (see above). Metipranolol is a nonselective beta blocking agent and reduces intraocular pressure minimally inanimals by decreasing cyclic-AMP synthesis in the ciliary body. Pilot studies have suggested... ↪ Read more

TIMOLOL MALEATE (OPHTHALMIC)

Indications / Pharmacology Timolol maleate is used primarily to prevent the development of primaryglaucoma in the contralateral eye of a dog which has developed primary glaucoma in one eye. It onlyreduces intraocular pressure 3-10 mmHg and, therefore is of minimal usefulness in patients... ↪ Read more

Glaucoma, Topical Agents

Note: Generally, once acute congestive primary glaucoma is noted in one eye it is treated as anemergency using mannitol/glycerin systemically, a systemic carbonic anhydrase inhibitor, a miotic andthen surgery is considered for lasting control of intraocular pressure. The following topical drugs are... ↪ Read more
