Beta adrenergic agonists have been shown to stimulate parathyroid hormone (PTH) secretion from isolated parathyroid cells. This action can be blocked with the β-adrenergic antagonist propranolol. This response appears to differ from that due to calcium itself, since β-blockade does not alter tissue response to calcium and high calcium concentration does not suppress the response to β-adrenergic stimuli (1-3). Short-term in-vivo studies in animals (4) and humans (5) have also shown PTH responsiveness to β-adrenergic agonists and elimination of this response by propranolol.
We recently found that propranolol significantly decreased serum levels of PTH, alkaline phosphatase, and the incidence of
