Urapidil is an antagonist of postsynaptic alpha 1 receptors, which leads to a diminution of the increased blood pressure by reducing the peripheral vascular resistance. With this pilot study we examined, whether it is possible to reduce the pregnancy-induced-hypertension with urapidil postpartum. The postpartum dosage of dihydralazine was diminished step by step and finally discontinued. We started i.v. treatment with urapidil at a diastolic blood pressure of more than 100 mm Hg. We observed a declining blood pressure in all cases without any tachycardia or serious side effects. Further studies will have to classify the rank of urapidil in the treatment of hypertension in preeclampsia.
