## Core Concept
Latanoprost is a prostaglandin F2α analogue used primarily in the treatment of glaucoma and ocular hypertension. It works by increasing the outflow of aqueous humor, thereby reducing intraocular pressure (IOP). This class of drugs is known for its efficacy in managing glaucoma.

## Why the Correct Answer is Right
Latanoprost, being a prostaglandin analogue, acts by stimulating the prostaglandin receptors in the eye, which leads to an increase in the uveoscleral outflow of aqueous humor. This mechanism results in a decrease in intraocular pressure, making it beneficial for patients with glaucoma or ocular hypertension. The correct answer highlights a specific characteristic or benefit of latanoprost.
