  • Title: Comparative effects of oxatomide on the release of histamine from rat peritoneal mast cells.
    Author: De Clerck F, Van Reempts J, Borgers M.
    Journal: Agents Actions; 1981 May; 11(3):184-92. PubMed ID: 6167156.
    Abstract:
    Oxatomide inhibits the release of histamine from rat peritoneal mast cells in vitro induced by C 48/80, antigen, anti-IgE and ionophore A 23 187, without effect on non-specific release by n-decylamine. Its effect is concentration- and pH-dependent and decreases with increasing extracellular Ca2+-concentrations. Prolonged incubation does not enhance the inhibition, which is lost after one single wash-out. Aminophylline and isoproterenol are not potentiated by oxatomide. The present study points to an effect of oxatomide on a Ca2+-dependent process at the level of cell membrane common to antigen, C 48/80 and ionophore A 23 187.
