  • Title: Effects of lipid A content, hydrocortisone and polymyxin B on endotoxin-induced decreases in in vivo drug metabolism.
    Author: Abernathy CO, Zimmerman HJ, Utili R.
    Journal: Microbios; 1987; 49(199):91-6. PubMed ID: 3033452.
    Abstract:
    Using hexobarbital sleeping and zoxazolamine paralysis time as indices of in vivo hepatic drug metabolism, the effects of endotoxin on drug action appear to be time- and dose-dependent and the lipid A moiety of endotoxin appears to be responsible for its inhibitory effects. These studies have also demonstrated that polymyxin B can ameliorate the adverse effects of endotoxin on drug metabolism. Since hydrocortisone protects mice from endotoxin lethality, but does not alter the prolongation of hexobarbital sleeping time caused by endotoxin, it is possible to separate the lethal effects of endotoxin from its effects on drug metabolism.
