[Influence of various non-steroid antirheumatic drugs on the electric potential between the gastric serosa and mucosa (author's transl)].

Non-steroid antirheumatic drugs inhibit the synthesis of prostaglandin, which results in a reduction in the efficacy of the gastric mucosal barrier. The transmural electric potential difference of the stomach wall would appear to be a useful criterion for mucosal barrier function. After 4 weeks of treatment with Indomethacin, Azapropazpone, Diclofenac or Phenylbutazone, a significant reduction in the gastric potential difference as compared with the pre-treatment measurement was observed. Accordingly, non-steroid antirheumatics give rise to a reduction in the functional efficacy of the mucosal barrier.
