Abstract
We investigated the effects of the calcium channel blocker amlodipine besilate on serum levels of adrenal androgens and insulin in 20 men with essential hypertension and obesity (age: 51.9+/-4.7 years, body mass index: 27.7+/-1.5 kg/m2). All were treated with amlodipine besilate (Norvasc) for 3 months. Blood pressure, fasting plasma glucose (FPG), HbA1c and serum levels of insulin, dehydroepiandrosterone (DHEA), DHEA sulfate (DHEA-S), and lipids were measured before and after a 3-month period. In 10 patients, 75 g oral glucose tolerance test (75 g-OGTT) was also performed. Amlodipine besilate treatment 1) lowered the fasting serum insulin level and total serum insulin level during 75 g-OGTT and 2) increased serum DHEA and DHEA-S levels. No changes in fasting plasma glucose, HbA1c and serum lipids were observed during treatment. We conclude that amlodipine besilate improves insulin resistance and consequently increases serum DHEA and DHEA-S levels.
