New York: Researchers have found that Lansoprazole, an over-the-counter acid reflux drug that is often taken by pregnant women, maybe a promising therapy to reduce preterm birth. The study, published in the journal JCI Insight also identified 12 other USFDA-approved drugs that are deemed safe in pregnancy. While the drugs encompass a variety of modalities, the researchers said they all appear to act on biological pathways that affect the immune response, which is implicated in preterm birth. (IANS)
