| Popis: | The present study attempts to assess the alteration in patterns of gastro-oesophageal reflux as assessed by 24-h oesophageal pH monitoring by varying degrees of H2-receptor blockade with famotidine. Subjects were 12 patients with complaints of daily heartburn who demonstrated at least 6% of acid mucosal contact time by 24-h ambulatory oesophageal pH monitoring. All subjects had a positive Bernstein test, and nine of the 12 subjects had erosive oesophagitis. The study was conducted as a double-blind crossover design utilizing 40 mg nocte, 20 mg b.d., and 40 mg b.d. and placebo treatments. Results indicated that all treatments significantly reduced the 24-h percentage acid contact time (P less than 0.05) compared to placebo. The two b.d. treatment regimens also significantly (P less than 0.05) reduced the number of episodes lasting longer than 5 min. Only the b.d. regimens successfully lowered the percentage of upright acid exposure. All treatments significantly (P less than 0.01) reduced the percentage of supine acid contact time, as well as the number of episodes lasting more than 5 min. It is concluded that gastro-oesophageal reflux disease may well require a b.d. dosing regimen with famotidine in order to achieve optimal mucosal healing and day time symptom control. |
