    Abstract:
    Relief of duodenal ulcer pain by aluminum hydroxide gel (AG) was compared with that obtained by a dummy gel (DG) in randomized trials. In 44 individual pain episodes, complete relief was obtained by 15-ml doses of AG in 79% and by DG in 45% (P less than 0.05). In 48 identical blind trials replicated at another hospital the difference was not significant. The gels were also tested against ulcer pain induced by intragastric acid instillation (Palmer test) in 35 patients; pain was relieved by AG in 63% and by DG in 62%. Presumed effectiveness in terminating ulcer episodes was studied in 65 patients admitted for pain; 37 received milk and cream hourly and 28 did not. All were treated with 15 ml of AG or DG during waking hours. Median time for complete disappearance of spontaneous pain was 3 days for AG and 7 days for DG, the same in both groups. In all patients the acid instillation test was repeated every few days. For the milk and cream group it became negative after 4 days with AG and after 6 days with DG. In 18 patients with gastric ulcer treated for 4 weeks AG led to greater reductions in size than did DG. A number of these trials indicate AG to be more effective than DG, but sampling and other methodological problems limit the certainty of any conclusions.
