title: [Animal experimental studies on the question of the interaction of paracetamol and acetylsalicylic acid].
abstract: The mutual effects of acetylsalicylic acid and paracetamol used in combination were studied in rats and mice. The antiexudative effects of acetylsalicylic acid in the edema tests on the hind paw of the rat, the antipyretic activity against yeast-fever of the rat and the analgesic effect on the inflamed hind paw of the rat was potentiated by paracetamol given simultaneously. The biosynthesis of prostaglandins in vitro by an enzyme preparation from bovine seminal vesicles was inhibited by acetylsalicylic acid and paracetamol in additive synergistic mode. The hepatotoxicity of paracetamol in mice measured by an increase of GOT in serum is antagonized by acetylsalicylic acid in dose-dependent manner. The suppression of the hepatotoxicity of paracetamol by acetylsalicylic acid in mice is not the consequence of interaction during absorption. The 3H-content of the liver following an oral dose of 3H-paracetamol is not influenced by acetylsalicylic acid given in combination with paracetamol. The mechanism of interactions between acetylsalicylic acid and paracetamol is discussed.
