Used primarily in ophthalmology, it is an active pharmaceutical ingredient in eye drops designed to reduce intraocular pressure. This makes it effective in managing conditions like glaucoma and ocular hypertension, helping to prevent optic nerve damage and vision loss. Its trans-isomer form enhances stability and efficacy, ensuring prolonged therapeutic action. It works by increasing the outflow of aqueous humor from the eyes, thereby lowering pressure. Its application is critical for patients requiring long-term treatment to maintain eye health and preserve vision.
