  • Title: Activation of acetaminophen oxidation in rat liver microsomes by caffeine.
    Author: Nouchi T, Lasker JM, Lieber CS.
    Journal: Toxicol Lett; 1986; 32(1-2):1-8. PubMed ID: 3738921.
    Abstract:
    Addition of caffeine in vitro stimulated the oxidative metabolism of acetaminophen by rat liver microsomes, resulting in increased formation of acetaminophen-glutathione (GSH) conjugates and increased covalent binding of acetaminophen to microsomal protein. This metabolic enhancement by caffeine was most prominent using liver microsomes from phenobarbital (PB)-treated rats. Liver microsomes obtained from rats treated with ethanol-oxidized acetaminophen at much faster rates than microsomes from control, PB-treated or 3-methylcholanthrene (3-MC)-treated animals. The stimulatory effect of caffeine was, however, minimal in liver microsomes obtained from ethanol-treated rats.
