title: Effect of mifepristone on dilatation of the pregnant and non-pregnant cervix.
abstract: The effect of the progesterone antagonist mifepristone on the cervix was investigated in two randomised double-blind placebo-controlled trials, the first in 30 women undergoing first trimester surgical termination of pregnancy and the second in 30 non-pregnant premenopausal women. 600 mg mifepristone, given orally 48 h before surgery, increased the mean preoperative cervical dilatation in both pregnant and non-pregnant treatment groups and also reduced the force required to dilate the pregnant and non-pregnant cervix.
