piperidines and aluminum-hydroxide--magnesium-hydroxide--drug-combination

To evaluate the safety and efficacy of cisapride in patients with gastroesophageal reflux disease.. Patients (N = 177) were randomized to double-blind treatment with cisapride (10 or 20 mg q.i.d.) or placebo for 12 wk. Efficacy was determined by pre- and poststudy endoscopies, symptom assessments by patient and physician, and Maalox consumption. Safety evaluations included vital signs, electrocardiograms, clinical laboratory tests, and reports of adverse events.. Cisapride 10 mg significantly reduced daytime and nighttime heartburn at 4 wk compared with placebo. Cisapride 20 mg reduced both daytime and nighttime heartburn at 4, 8, and 12 wk, compared with placebo, and was also significantly superior to the 10-mg dose at 12 wk. The percent of patients with endoscopic healing was significantly higher with cisapride 20 mg than with placebo [healing: 51 vs 36% (p < or = 0.044)]. Maalox usage declined significantly with cisapride 20 mg compared with placebo. No clinically significant changes in safety variables occurred with cisapride. The most frequently reported adverse events in the cisapride group were diarrhea, headache, and sinusitis.. Cisapride 10 and 20 mg q.i.d. were safe and well tolerated in a population of patients with mild-to-moderate gastroesophageal reflux disease. Both symptoms and endoscopic grade improved after 12 wk of treatment with cisapride 20 mg q.i.d.

We conducted a double-blind study comparing two dosage regimens of a prokinetic drug, cisapride (10 mg q.d.s. and 20 mg b.d.), with a low dose of a H2-receptor antagonist (150 mg ranitidine b.d.) in the treatment of 155 patients with reflux oesophagitis as determined by endoscopy. The active treatment took 8 to 12 weeks depending on whether complete healing was found at endoscopy. Improvement in oesophagitis grades from baseline to endpoint was observed in 68% of patients in the 10 mg cisapride q.d.s. group, 83% in the cisapride 20 mg b.d. group and 81% in the ranitidine group (N.S.). At endpoint, the percentages of endoscopically cured patients with initial grades I or II were 52% for 10 mg cisapride q.d.s., 71% for 20 mg cisapride b.d. and 80% for ranitidine (N.S.). The proportional improvement of the overall reflux symptom score (60%) also showed no significant difference between the three groups. In the treatment of mild reflux oesophagitis (grades I and II) similar results can be expected from 20 mg cisapride b.d. and 150 mg ranitidine b.d. As the results of the two dosage regimens of cisapride were not different, the 20 mg twice daily regimen is preferred because it will improve patient compliance. It is concluded that in reflux oesophagitis grades I and II, the efficacy of 20 mg cisapride b.d. and 150 mg ranitidine b.d. are broadly similar.
