Blood-clot drug ben­e­fit

The Guardian Weekly - - Discovery -

Im­me­di­ate treat­ment with a cheap clot-sta­bil­is­ing drug could save the lives of thou­sands of peo­ple each year, in­clud­ing women with se­vere bleed­ing af­ter child­birth, a study has found. A meta-anal­y­sis of more than 40,000 pa­tients found that the like­li­hood of death due to blood loss was re­duced by more than 70% if tranex­amic acid was ad­min­is­tered straight af­ter in­jury or birth. But the ef­fec­tive­ness of the drug di­min­ished over time. The chances of sur­vival fell by 10% for each 15-minute delay, with no ben­e­fit seen when ad­min­is­tered af­ter three hours. Post­par­tum haem­or­rhage is the lead­ing cause of ma­ter­nal death world­wide, killing about 100,000 women a year.
