Official title

Effect of Combined Estradiol and Drospirenone Treatment Versus Combined Estradiol and Medroxyprogesterone Acetate Treatment on Endothelial Function: A Crossover Study

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

This study compares the effects of two common hormone medications on the heart and blood vessels of healthy post-menopausal women over the age of 45. The study will take place over the course of about 5 months. Each subject will take two different medications over two six-week periods. They will be randomized at the beginning of the study to either estradiol+medroxyprogesterone acetate or estradiol+drospirenone for the first period, and will receive the other medication the second six-weeks of the study. At the very beginning of the study and at the end of each six-week treatment period, subjects will come to the hospital various tests including non-invasive blood vessel imaging tests, blood draws to test the levels of certain hormones in the body, an oral glucose tolerance test, a test to monitor renal blood flow, and 24-hour blood pressure monitoring. Between treatment periods, there will be a four-week medication-free washout period.
