Fifty-eight patients with endoscopically confirmed benign gastric ulceration were randomly allocated to treatment with 150 mg ranitidine twice daily, placebo matching ranitidine twice daily, or 200 mg cimetidine three times daily and 400 mg at night. Patients were endoscoped at monthly intervals for up to 3 months, the endoscopist being unaware of the treatment. Significantly more ulcers (p less than 0.05) had healed after 2 months of ranitidine (14 of 18, 78%) and cimetidine (17 of 20, 85%) than with placebo (9 of 20, 45%; p less than 0.05) and after 3 months of ranitidine (15 of 18, 88%) and cimetidine (18 of 20, 90%) than with placebo (11 of 20, 55%; p less than 0.05). Forty-eight patients with healed ulcers were randomly allocated in a double-blind prophylactic study to receive 150 mg ranitidine at night or matching placebo. After 6 months recurrent ulcers were found in 2 of 24 (8%) of patients receiving ranitidine and 10 of 24 (42%) of patients receiving placebo (p less than 0.05). These data indicate that H2-receptor antagonists are significantly better than placebo in healing gastric ulceration and that ranitidine and cimetidine are equally effective. Ranitidine is significantly superior to placebo in preventing gastric ulcer recurrence.

Ranitidine (150 mg twice daily) was compared with placebo in 42 patients with gastric ulcer. The study was conducted as a double-blind trial for one month, followed by an open assessment of one, two, and three months of ranitidine in the patients with persistent ulceration. Thirty-eight patients completed the double-blind trial. Repeat endoscopy confirmed complete healing in 16 of the 21 who had received ranitidine and five of the 17 who had received placebo (p less than 0.01). The remaining 17 patients with persistent ulceration participated in the open assessment. The combined cumulative healing rates of ranitidine at four, eight, and 12 weeks were 73%, 88%, and 97%. There were no adverse effects or unusual reasons for withdrawal from the study (four patients). Ranitidine appears to be a safe and highly effective treatment of gastric ulceration, with about 90% of ulcers healed after eight weeks.

50 patients with acute gastrointestinal bleeding (GIB) were randomly allocated to treatment with i.v. Ranitidine 50 mg b.d., or to a standard conservative therapy. When possible i.v. administration was replaced by oral ranitidine 150 mg b.d. for a total of up to 10 days. Three subgroups included gastric ulcer, duodenal ulcer and haemorrhagic gastritis. The criteria were: the need for blood replacement, comparison of the endoscopic appearance before and after therapy, and the final outcome of treatment, including the need for surgery. Ranitidine appeared to be superior to the standard treatment, the advantages being due largely to the gastric ulcer cases.

One hundred and seventy seven duodenal ulcer and eighty-one gastric ulcer patients were treated with either ranitidine or placebo in a prospective double-blind study. Groups treated with active drug and placebo were comparable and ulcer healing was assessed by weekly endoscopic examinations. Ranitidine was shown to accelerate the rate of spontaneous ulcer healing in both duodenal and gastric ulcer. This acceleration is significant after one week of treatment in duodenal ulcer and from three weeks onwards in gastric ulcer. The ulcer healing rate after three weeks treatment with ranitidine was 85.5% in duodenal ulcer, and 72.5% in gastric ulcer which was significantly higher than in the placebo group where it was 51.7% and 41.5% respectively (P less than 0.005 and P less than 0.01). Treatment with ranitidine for a maximum of six weeks healed 97.1% of duodenal ulcer patients (172 out of 177) and 96.5% of gastric ulcer patients (77 out of 81). Out of total of 258 patients only 9 failed to heal. No adverse events were seen with ranitidine and it would appear free of the side effects that have been seen with cimetidine. In addition there were no significant changes in blood haematology or clinical chemistry parameters. Ranitidine is also given in a more convenient regimen, 150 mg daily as compared to 200 mg three times daily and 400 mg nocte with cimetidine.

A multicenter trial of oral ranitidine 150 mg bid was conducted in 41 patients with duodenal and 30 with gastric ulcers. Patients were randomly allocated in double-blind fashion to 4 wk treatment with either ranitidine or placebo, after which all unhealed patients were given 4 wk on the active drug without breaking the original allocation code. After 4 wk of treatment the healing rate associated with ranitidine was significantly superior to that of placebo in both duodenal and gastric ulcer patients. Further improvement in cumulative healing rates was observed after the 2nd month of the study. After the allocation code was broken and all patients had had the opportunity of up to 8 wk on the active drug, there remained only a single unhealed pyloric ulcer. No serious adverse effects or biochemical abnormalities were observed. Ranitidine is a potent and well-tolerated H2 antagonist. Therapy for 4 or 8 wk is highly effective in the treatment of uncomplicated gastroduodenal ulcer.

Prophylactic maintenance therapy for one year using ranitidine 150 mg at night or a placebo was assessed in 68 patients whose gastric or duodenal ulcers had previously healed after therapy with ranitidine 150 mg twice daily or placebo. Gastroscopy was carried out on symptomatic relapse and at the end of the year. Of the duodenal ulcer group, seven out of 20 relapsed on ranitidine compared with 15 out of 17 on placebo (p less than 0.001). Of the gastric ulcer group one of 15 patients relapsed on ranitidine compared with 11 of 16 patients on placebo (p less than 0.005). There were no adverse effects from ranitidine during the trial period. Ranitidine in low dose maintenance therapy is therefore reasonably effective in the prevention of relapse of duodenal ulcers and appears to be particularly effective in preventing relapse of gastric ulcers at least for one year. As gastric ulcers occur more frequently in the older patients in whom there are often medical contraindications to surgery, maintenance treatment may be appropriate for many such patients.

The effect of treatment for 4 weeks with the H2-receptor antagonist ranitidine 200 mg daily on ulcer healing, clinical symptoms and antacid consumption, and on gastric acid secretion, was studied in a double blind trial in 48 patients with a total of 50 endoscopically confirmed duodenal, prepyloric or corporeal gastric ulcer. Patients whose ulcers did not show complete healing within 28 days were continued openly on ranitidine for up to a further 4 weeks. Endoscopy, basal gastric acid secretion (BAO) and pentagastrin-stimulated maximal secretion (PAO) studies were performed at 2-week intervals. After four weeks, 73% of the gastro-duodenal ulcers in the ranitidine group showed complete healing versus 42% in the placebo group (p less than 0.05). Gastric acid secretion was considerably inhibited both under basal (89%; p less than 0.001) and maximal challenge (71%; p less than 0.001) conditions. The inhibitory effect was still pronounced 13-15 h after administration of ranitidine 100 mg. Symptoms and the need for antacids were significantly reduced. Ranitidine appears to be an efficacious, safe and well tolerated medicine principle for the treatment of gastro-duodenal ulcer disease.

We compared the clinical effectiveness and endoscopic results of ranitidine and cimetidine treatment; 71 outpatients, all affected with benign gastric ulcer, were selected for the study (43 type I, 7 type II and 21 type III, according to Johnson's classification). The patients were treated randomly for 4 weeks with ranitidine (300 mg daily) or cimetidine (1 g daily). An endoscopic examination was repeated within 3 days after the end of the treatment. Clinical checks were performed weekly in order to monitor the clinical course of pain and antacid consumption, according to the patient's needs. The patients who did not demonstrate complete healing on endoscopic examination were treated for an additional 4 week period. At the end of this 4 week period, another endoscopic examination was done. Thirty-six patients treated with ranitidine and 33 with cimetidine completed the first period of therapy. The two groups were homogeneous with regard to sex, age, duration of disease, smoking habits, alcohol consumption, and type and size of ulcer. Ranitidine and cimetidine treatments did not demonstrate any significant difference with regard to ulcer healing after the 4th or the 8th week of therapy. Both ranitidine and cimetidine were less effective in healing type I than type II and III G.U., at the 4th week of treatment. No significant differences between the two groups were noted with regard to pain or weekly antacid consumption. No significant side effects were reported.

A randomized, double-blind study was done to determine the efficacy and safety of ranitidine in the short-term treatment of duodenal and benign gastric ulcers. Fifty-one patients with duodenal ulcer and 44 patients with gastric ulcer were admitted to the study. Forty-two duodenal ulcer patients and 36 gastric ulcer patients completed the study. In the duodenal ulcer group, 14 (70%) of 20 patients on ranitidine and one (4.5%) of 22 patients on placebo were healed. In the gastric ulcer group, 12 (75%) of 16 patients on ranitidine and six (30%) of 20 patients on placebo were healed. The healing percentages in both groups significantly favored ranitidine. Ranitidine was also significantly better than placebo in relieving ulcer pain. No side effect could be attributed definitely to ranitidine.

Ranitidine 150 mg twice daily is effective for the treatment of gastric ulcers. We proposed that ranitidine 300 mg once daily would also be effective. In a randomized, double-blind, placebo-controlled, multicenter, parallel-group study, adults with an endoscopically verified acute gastric ulcer > or = 5 mm were treated with either ranitidine 300 mg (n = 183) or placebo (n = 178) at bedtime for up to 12 wk. Gastric ulcer healing, determined by endoscopy, was achieved in 65% and 89% of ranitidine-treated patients by 6 and 12 wk, compared with 45% and 72% of placebo-treated patients by 6 wk and 12 wk (p < 0.001). Throughout the 12-wk study, ranitidine 300 mg was significantly more effective than placebo in relieving pain (p < 0.05), with ranitidine-treated patients also using fewer antacid tablets. Ranitidine 300 mg had a safety profile similar to that of placebo. We conclude that ranitidine 300 mg at bedtime is safe and effective for healing acute gastric ulcers.
