16-Phenoxy tetranor PGE2 is primarily used in the field of ophthalmology as an active ingredient in eye drops for the treatment of glaucoma and ocular hypertension. It works by increasing the outflow of aqueous humor from the eye, thereby reducing intraocular pressure. This mechanism helps in preventing optic nerve damage and preserving vision in patients with these conditions. Additionally, it is being researched for its potential applications in promoting wound healing and reducing inflammation in various tissues, owing to its prostaglandin-like properties. Its efficacy and safety profile make it a valuable component in therapeutic formulations aimed at managing eye-related disorders.
