Latanoprost

Latanoprost, sold under the brand name Xalatan among others, is a medication used to treat increased pressure inside the eye (intraocular pressure). This includes ocular hypertension and open-angle glaucoma. Latanaprost is applied as eye drops to the eyes. Onset of effects is usually within four hours, and they last for up to a day. Common side effects include blurry vision, redness of the eye, itchiness, and darkening of the iris. Latanoprost is in the prostaglandin analogue family of medications. It works by increasing the outflow of aqueous fluid from the eyes through the uveoscleral tract. Latanoprost was approved for medical use in the United States and the European Union in 1996. It is on the World Health Organization's List of Essential Medicines. Latanoprost is available as a generic medication. In 2023, it was the 67th most commonly prescribed medication in the United States, with more than 9 million prescriptions. It is available as a fixed-dose combination with netarsudil as netarsudil/latanoprost and with timolol as latanoprost/timolol.
