The present IIT (Investigator-Initiated Trial) study is a prospective, randomised, placebo-controlled, double blind trial. Women hospitalised with signs of preterm birth can be recruited for the study. Participants will take study medication for 2 weeks (or until birth) and fill out a questionnaire at 3 time points (at baseline, after 1 week and after 2 weeks) to assess state of anxiety and sleep quality. Furthermore, information regarding adverse events and the further course of the pregnancy are recorded.
Preterm birth is one of the leading causes for mortality and morbidity in newborns and preterm contractions are the cause of a considerable part of preterm deliveries. In the treatment of preterm labour, tocolytic medications are often used that are associated with numerous side effects for the pregnant woman, which limits their use in time. Preparations from Bryophyllum pinnatum, which demonstrated excellent tolerability, constitute a safe alternative for tocolytic treatment. It was introduced as an alternative tocolytic by anthroposophic medicine in Europe and is used as a monotherapy or add-on therapy for preterm labour in many perinatal clinics in Switzerland today. In vitro studies support the use of B. pinnatum as a tocolytic. In addition, there are also limited options for the treatment of mental disorders and sleep disturbances during pregnancy. Anxiety plays a major role in the development of preterm labour and often leads to administration of tocolytics longer than necessary. Preparations from B. pinnatum have traditionally been in the treatment of anxiety. Improvements of sleep quality in pregnant women during treatment with B. pinnatum preparations were already shown in previous studies. This exploratory study aims at investigating the effects of B. pinnatum for the treatment of anxiety in patients with signs of preterm birth.
