Role of pepsin in the development of indomethacin-induced antral ulceration in the rat.
    Alimentary pharmacology & therapeutics, 1995, Volume: 9, Issue:2

    To examine the effects of a pepsin inhibitor, pepstatin-A, a long acting H2-receptor blocker, loxtidine, exogenous pepsin and exogenous acid against indomethacin-induced antral ulceration in the rat.. Indomethacin (60 mg/kg s.c.) caused antral ulceration in fasted/re-fed rats over a period of 4 h. Ulceration was prevented in a dose-dependent manner by treatment with pepstatin-A (0.1-1 mg.kg hourly) or loxtidine (3 mg/kg) given orally. Acidified methylcellulose (1 mL hourly per os) enhanced damage and also prevented protection by loxtidine (3 mg/kg per os). The protection by pepstatin-A was not altered by treatment with acidified methylcellulose but was reversed by treatment with a 10-fold excess of pepsin.. These studies suggest that mucosal degradation by pepsin, rather than direct damage by luminal acid, was the major factor in the development of indomethacin-induced antral ulceration in the rat.
