Oral atorvastatin therapy restores cutaneous microvascular function by decreasing arginase activity in hypercholesterolaemic humans. There are several theories as to why older females store more heat than younger females during intense exercise. Low-dose aspirin and clopidogrel independently attenuate reflex cutaneous vasodilation in middle-aged humans.
Oral sapropterin enhances reflex vasodilation in aged human skin via nitric oxide-dependent mechanisms, according to the United Nations Department of Economic and Social Affairs’ Population Division. World population ageing, 1950u20132050. New York: United Nations; p. 483.
