Prostaglandin analogues are synthetic compounds that mimic the action of natural prostaglandins, which are lipid compounds involved in various physiological processes. These analogues are commonly used in medicine to treat conditions such as glaucoma and ocular hypertension by increasing the outflow of fluid from the eye, thereby reducing intraocular pressure. In addition to eye care, prostaglandin analogues are also used in obstetrics to induce labor and manage certain reproductive health issues. They work by promoting uterine contractions and softening the cervix, facilitating childbirth. Overall, these compounds play a significant role in both ophthalmology and gynecology.
