Summary
This trial will test whether the ENaC inhibitor amiloride can improve endothelial function and arterial stiffness in obese, insulin resistant subjects. The trial will involve pre and postmenopausal women and age-matched men.
Who is the study for?
This trial is for obese or overweight adults aged 30-70 with a BMI of 25.1-50 kg/m2 or certain waist measurements, plus one other metabolic syndrome feature like high triglycerides. It's not for smokers, heavy drinkers, those on specific heart/kidney medications, diabetics, very active individuals, pregnant/breastfeeding women, and people with recent severe health issues.
What is being tested?
The study tests if amiloride (an ENaC blocker) can improve blood vessel function and reduce artery stiffness in obese insulin-resistant subjects compared to a placebo. The participants are pre/postmenopausal women and age-matched men who will be randomly assigned to the treatments.
What are the potential side effects?
Possible side effects of amiloride include elevated potassium levels which could affect heart rhythm, dizziness due to low blood pressure especially after standing up quickly from sitting/lying down positions, muscle cramps or weakness.
