Tafluprost, with the CAS number 209860-87-7, is a pharmaceutical substance used in the treatment of glaucoma and ocular hypertension. It is classified as a prostaglandin analog and works by reducing intraocular pressure in the eye. Tafluprost is commonly administered as eye drops and helps to increase the outflow of aqueous humor from the eye, thus lowering the pressure inside the eye. It is a selective FP prostaglandin receptor agonist, specifically targeting the FP (prostaglandin F2α) receptor. Tafluprost is known to be well-tolerated, and its most common side effects include ocular discomfort, conjunctival hyperemia, and periocular hyperpigmentation.
