title: [Clinical evaluation and pH control in patients with duodenal ulcer treated with ranitidine].
abstract: In 31 duodenal ulcer patients treated with ranitidine at regular doses, during four weeks we could prove: a) by endoscopy, the ulcer "epithelization" in 13 patients (41.93%) and a positive response in the other cases; b) a high increase in the intragastric pH after the treatment, with an increase rate of pH 3.288 over the initial medium levels. The clinical-endoscopical response as well as an important increase in the intragastric pH, show the effectiveness of the ranitidine in the treatment of the duodenal ulcer.
