[Prolonged effect of an antacid treatment on changes in gastric potential difference induced by aspirin in man]

In ten healthy volunteers, we evaluated the effects of a 6 days antacid treatment (Rocgel) on the aspirin induced changes in gastric potential difference (PD). In this placebo controlled cross-over study, PD was measured twelve hours after the last take of the antacid. Aspirin induced drop of PD was less pronounced after antacid compared to placebo; maximal fall of PD and area upper the curve decreased (p less than 0.001). This effect was observed twelve hours after the last take of the antacid. It may suggested a long-term protective effect on the gastric mucosa.
