Prostaglandin Analog

prostaglandin analog

A prostaglandin analog is a type of medicine that acts like naturally occurring prostaglandins in the eye. These drugs are most commonly used to lower pressure inside the eye by changing how fluid drains. They work mainly by increasing the outflow of aqueous humor through the uveoscleral pathway, which reduces intraocular pressure. Because lowering pressure is the main way to slow or prevent damage to the optic nerve, these medicines are a cornerstone of glaucoma treatment. Examples include latanoprost, bimatoprost, and travoprost, which are often prescribed as once-daily eye drops. Side effects tend to be local and can include eye redness, irritation, darker iris color over time, and longer or thicker eyelashes; systemic side effects are uncommon. Some newer formulations are designed to release the medicine over weeks or months, which can help people who have trouble using daily drops. Doctors choose these drugs because they are effective, generally well tolerated, and easy to use, but they still require regular follow-up to check eye pressure and eye health. Understanding how they work and what to expect helps people and caregivers make informed decisions about long-term eye care.
