Effect of two oral doses of 17β‐estradiol associated with dydrogesterone on thrombin generation in healthy menopausal women: a randomized double‐blind placebo‐controlled study

Oral hormone therapy is associated with an increased risk of venous thrombosis. Drug agencies recommend the use of the lowest efficient dose to treat menopausal symptoms for a better risk/ratio profile, although this profile has not been totally investigated yet. The aim of the study was to compare the effect of the standard dose of 17β‐estradiol to a lower one on thrombin generation (TG).
