Tafluprost free acid (AFP-172) is primarily used in ophthalmology for the treatment of glaucoma and ocular hypertension. As the free acid form of Tafluprost, a synthetic prostaglandin analogue, it effectively reduces intraocular pressure by enhancing the outflow of aqueous humor. This mechanism helps prevent optic nerve damage and preserves vision. Commonly formulated as eye drops, it provides an efficient and safe therapeutic option for long-term eye health management, slowing the progression of vision loss in patients.
