Abstract
The effect of 2 weeks treatment with propranolol or metoprolol on skin blood flow (SBF) at rest was examined in 12 diabetic patients with essential hypertension in whom gross large vessel disease had been excluded. Neither drug significantly altered resting skin blood flow. However we cannot exclude an important difference between the two beta-adrenoceptor blockers because of the great variability of SBF within subjects. A larger study and/or more accurate methods of measuring SBF are needed to determine if beta 1-selective adrenoceptor antagonists differ from non-selective beta-adrenoceptor blockers with respect to skin blood flow.
