Understanding Dorzolamide: An In-Depth Overview
Dorzolamide is a potent carbonic anhydrase inhibitor primarily formulated as eye drops. It plays a crucial role in managing elevated intraocular pressure, a common feature in conditions like open-angle glaucoma and ocular hypertension. By reducing the aqueous humor production within the eye, dorzolamide helps to safeguard the optic nerve from damage caused by excessive pressure.
Mechanism of Action
This medication works by inhibiting the enzyme carbonic anhydrase, which is vital in the biochemical pathway responsible for aqueous humor synthesis. When this enzyme’s activity is suppressed, the production of fluid inside the eye diminishes, leading to a corresponding decrease in intraocular pressure. This targeted approach helps patients maintain better eye health and prevent vision loss.
Forms and Usage Instructions
Dorzolamide is typically available in a 2% ophthalmic solution. It is often prescribed as a twice or thrice daily treatment, depending on the severity of the condition and the doctor’s recommendations. Patients should strictly adhere to prescribed dosages and usage schedules to ensure optimal results.
