the effect of administering low doses of famotidine or ranitidine alone or in combination with an m1-receptor-selective antagonist , pirenzepine , on night intragastric acidity was evaluated in 16 active duodenal ulcer patients to verify 1 ) whether anticholinergics and h2-antagonists have a synergic effect on inhibition of night gastric acidity , and 2 ) whether patients with vagal hypertone are more sensitive to anticholinergics than the remainder of the duodenal ulcer population .
