An information about the experience with DILATOL-treatment of 11 patients suffering from EPH-gestosis with hypertonia as the main symptom, is given. In all cases it was possible to reduce the systolic and diastolic blood-pressure. In long-time treatment an increasing resistance to therapy was noticed. In any case the treatment has to be combined with a frequent medical control of the gravidity with respect to the foetus and the placenta, to determine the right moment of the premature finishing of the gravidity, which is often necessary. Although no child of our 11 patients, died, it wasn't possible to prove the fact, that the perinatal mortality in the case of heavy EPH-gestosis after treating with beta-adrenergic substances is reduced. There weren't noticed any detrimental consequences to mother and child after treating with DILATOL within a space of time up to 4 weeks up to a total amount of 500 mg.
