Preeclampsia Severe, Preeclampsia Second Trimester, Preterm Birth Complication
Conditions
Brief summary
A recent randomized controlled trial by Cluver et al included 180 women with preterm pre-eclampsia between 26+0 to 31+6 weeks' gestation undergoing expectant management: 90 were randomised to extended release metformin and 90 to placebo. Investigators found that extended release metformin (3g daily) can prolong gestation in women with preterm pre-eclampsia. Combination metformin and esomeprazole has shown promise in the treatment of preeclampsia as both agents reduce placental and endothelial secretion of soluble fms-like tyrosine kinase 1 (sFlt-1) and soluble endoglin, and reduce endothelial dysfunction.
Interventions
Combination 2 g of oral extended release metformin, Esomeprazole 20mg daily until delivery.
