ENAC Blockade and Arterial Stiffness

Insulin Resistance Clinical Trial

Official title:
Estrogen Receptor Alpha Signaling in Endothelial Cells Exacerbates Arterial Stiffening Via Upregulation of ENaC in Insulin Resistant Females

Clinical Trial Summary

To determine whether treatment with the ENaC inhibitor, amiloride, improves endothelial function and arterial stiffness in obese insulin resistant subjects in a randomized placebo-controlled trial examining pre and postmenopausal women and age-matched men.

Clinical Trial Description

Overweight/obese males, pre- and post-menopausal females with insulin resistance, 30-70 years of age will be recruited. Following screening, eligible men and women will be randomly assigned to either amiloride (max dose 5mg) or placebo in a double-blinded design manner. After randomization, subjects will be scheduled for an outpatient visit to the undergo baseline assessment of arterial stiffness (carotid femoral pulse wave velocity - cfPWV) and endothelial function (brachial popliteal artery flow mediated dilation). Subject assessment will be repeated at 12 weeks and at 24 weeks. ;
