Prostaglandin F2α 1,15-lactone is primarily utilized in medical and pharmacological research due to its role as a stable analog of prostaglandin F2α. It is often employed in studies focusing on reproductive biology, particularly in understanding and managing conditions related to the female reproductive system. Its application extends to inducing luteolysis, which is useful in synchronizing estrus cycles in livestock, thereby improving breeding efficiency. Additionally, it is investigated for its potential in treating glaucoma, as it helps reduce intraocular pressure by enhancing the outflow of aqueous humor. In experimental settings, it serves as a valuable tool for studying the mechanisms of prostaglandin action and its effects on various physiological processes.
