There is no high quality evidence to indicate if IV oxytocin should be stopped once a woman reaches active labor in order to reduce the incidence of women requiring caesarean sections. Use of mifepristone has been described but is rarely used in practice. Relaxin has been investigated, but is not currently commonly used. mnemonic; ARNOP: Antiprogesterone, relaxin, nitric oxide donors, oxytocin, prostaglandins

Non-pharmaceutical
Membrane sweep, also known as membrane stripping, Hamilton maneuver, or "stretch and sweep". The procedure is carried out by a midwife or doctor as part of an internal vaginal examination. The midwife or doctor puts a couple of lubricated, gloved fingers into the womens vagina and inserts their index finger into the opening of the cervix or neck of the womb. They then use a circular movement to try to separate the membranes of the amniotic sac, containing the baby, from the cervix. This action, which releases hormones called prostaglandins, may prepare the cervix for birth and may initiate labour. Artificial rupture of the membranes (AROM or ARM) ("breaking the waters")
Extra-amniotic saline infusion (EASI), in which a Foley catheter is inserted into the cervix and the distal portion expanded to dilate it and to release prostaglandins. Cook Medical Double Balloon known as the Cervical Ripening Balloon with Stylet for assisted placement is FDA approved. The Double balloon provides one balloon to be inflated with saline on one side of the Uterine side of the cervix and the second balloon to be inflated with saline on the vaginal side of the cervix.
Labor induction is the process or treatment that stimulates childbirth and delivery. Inducing (starting) labor can be accomplished with pharmaceutical or non-pharmaceutical methods. In Western countries, it is estimated that one-quarter of pregnant women have their labor medically induced with drug treatment. Inductions are most often performed either with prostaglandin drug treatment alone, or with a combination of prostaglandin and intravenous oxytocin treatment. Medical uses
Commonly accepted medical reasons for induction include:

Postterm pregnancy, i.e. if the pregnancy has gone past the end of the 42nd week. Intrauterine fetal growth restriction (IUGR). There are health risks to the woman in continuing the pregnancy (e.g. she has pre-eclampsia). Premature rupture of the membranes (PROM); this is when the membranes have ruptured, but labor does not start within a specific amount of time. Premature termination of the pregnancy (abortion). Fetal death in utero and previous history of stillbirth. Twin pregnancy continuing beyond 38 weeks. Previous health conditions that puts risk on the woman and/or her child such as diabetes, high blood pressure
High BMIInduction of labor in those who are either at or after term improves outcomes for newborns and decreases the number of C-sections performed. Methods of induction
Methods of inducing labor include both pharmacological medication and mechanical or physical approaches.Mechanical and physical approaches can include artificial rupture of membranes or membrane sweeping.
