Animal studies suggest that some angiotensin converting enzyme inhibitors augment endothelium-dependent vasorelaxation. We aimed to determine if captopril augments endothelium-dependent vasodilation in middle-aged hypertensive patients. By using strain-gauge plethysmography, forearm vasodilation evoked with intra-arterial acetylcholine (4, 8, 16, and 24(More)
An orally effective, nonpeptide vasopressin V1 receptor antagonist, OPC-21268 was produced for possible human use. We investigated the effects of OPC-21268 on the vascular effects of intra-arterially infused arginine vasopressin in human forearm vessels. The brachial artery was cannulated for drug infusions and direct measurement of arterial pressure.(More)
