Which eye drop medication helps reduce intraocular pressure?

Prostaglandin analogs are a class of medications commonly used to lower intraocular pressure (IOP) in patients with glaucoma or ocular hypertension. These medications work by increasing the outflow of aqueous humor, the fluid produced inside the eye, thus reducing the pressure. They enhance the uveoscleral pathway, helping the eye to drain this fluid more effectively.

Prostaglandin analogs are known for their effectiveness and relatively favorable side-effect profile, making them a first-line treatment option in many cases of elevated intraocular pressure.

In contrast, while beta-blockers are also used for managing IOP, they function differently by reducing the production of aqueous humor rather than enhancing its outflow. Antihistamines are primarily used to treat allergic reactions and do not have an effect on intraocular pressure. Antibiotics are used to treat bacterial infections and are unrelated to the management of IOP.
