Nine uraemic patients not yet on dialysis received IV 1 microgram/kg/min of propranolol for 85 min after a priming dose of 1 mg. Fifteen days later six of them received IV 1.2 microgram/kg/min of metoprolol after a priming dose of 1.2 mg. Plasma concentrations of PTH and calcitonin decreased significantly with propranolol but not with metoprolol. No change was observed with either drug as regards plasma concentration of total and ionised Ca and PO4. Heart rate was decreased similarly with both drugs. We conclude that (i) propranolol acutely suppresses PTH and Calcitonin secretion in uraemic patients. This warrants further studies to assess its long term effects on the secretion of these hormones and on renal osteodystrophy; (ii) the contrast between the significant effect of propranolol and the lack of effect with metoprolol supports the concept that PTH and CT secretion are moderated through specific beta 2 receptors.
