Summary

This study is designed to answer the question as to whether the sympathetic nervous system is an important determinant of bone metabolism in humans.

Detailed description

In postmenopausal women, who have increased sympathetic outflow, to test the hypothesis that treatment with low doses of a non-selective β-blocker (propranolol) will increase serum markers of bone formation and reduce markers of bone resorption (Aim 1a); and using increasingly β1-AR (adrenergic receptor) selective blockers (atenolol and nebivolol), to better define the β-adrenergic receptor selectivity (β1 versus β2) in the regulation of bone turnover by sympathetic outflow in humans.
