Tiaprost, marketed under the name Iliren, is primarily used in the field of veterinary medicine, particularly for the treatment of glaucoma in dogs. It functions by reducing intraocular pressure, which helps prevent damage to the optic nerve and preserves vision. The compound is a prostaglandin analog, which promotes the outflow of aqueous humor from the eye, thereby lowering pressure effectively. Its application is crucial in managing chronic glaucoma, providing a therapeutic option that improves the quality of life for affected animals. Regular administration as prescribed by a veterinarian ensures optimal management of the condition.
