Prostin is a brand name for a medication that contains the active ingredient prostaglandin E2, also known as dinoprostone. It is used in various medical settings, primarily in obstetrics and gynecology, to manage different aspects of childbirth and related conditions. Prostin can be administered to induce labor in pregnant women who are at or near term, to soften and dilate the cervix in preparation for labor induction, and to manage certain types of miscarriages. It works by mimicking the action of naturally occurring prostaglandins in the body, which are involved in initiating labor by causing the cervix to soften, dilate, and the uterine muscles to contract. Prostin is available in different forms, including vaginal tablets, gels, and suppositories, allowing for flexible administration depending on the specific medical need and patient condition.
