title: Acetaminophen protects human erythrocytes against oxidative stress.
abstract: Acetaminophen protects human erythrocytes against various modes of oxidative stress. Protection against ozone-induced damage can be explained by a direct scavenging reaction between the drug and ozone. With t-butylhydroperoxide acetaminophen appeared to be an effective scavenger of radicals, generated in secondary reactions. The protection by acetaminophen against t-butylhydroperoxide- and hydrogen peroxide-induced lipid peroxidation and K+-leakage can be explained along these lines. In all cases the protective effect of acetaminophen was attended with covalent binding of acetaminophen to membrane proteins.
