Postpartum Hemorrhage Reduction With Oral Tranexamic Acid: a Clinical Trial

This is a multicentre randomized placebo-controlled double-blinded phase IV study among 1000 women in Sweden and South Africa on the effect of oral tranexamic acid on PPH after vaginal delivery. The main purpose of the study is to evaluate the effect of orally administered tranexamic acid (TA) compared to placebo on rate of postpartum hemorrhage (PPH) after vaginal birth. Participants will be randomized to receive either 20 ml (2g) of the investigational medicinal product (TA100mg/ml) or 20ml of a placebo solution during labor. Our main endpoint, assessed at 24 hours after delivery is PPH defined as blood loss \>=500ml and assessed both by weight and pre-postpartum hemoglobin (Hb) decrease \>10 units difference in vaginal deliveries. This RCT was preceded by a pilot intervention, included in the current protocol, aiming to assess uptake of oral forms of Tranexamic acid (TA) during active labour. The study took place at Södersjukhuset, Stockholm, Sweden between December 2022 and February 2023 among 51 women ≥ 36 gestational weeks with planned vaginal delivery who were randomized 1:1:1:1 to receive two grams of TA as oral solution, tablets, effervescent tablets, or 1g of intravenous (IV) TA, near full cervical dilatation. Blood samples were taken 30, 60, 120, 240, 360, and 480 minutes after TA administration. Plasma concentration of TA was measured using Liquid Chromatography-Tandem Mass Spectrometry. Mean values were compared between groups using ANOVA. Our main outcomes meas…
