Sucralfate suspension 1 g/10 ml four times per day was found to be significantly better than placebo for the healing of active duodenal ulcer. An eight-week, double-blind, randomized, placebo-controlled, parallel-group multicenter study was conducted. A total of 292 patients were evaluated. Ulcer healing was evaluated by endoscopy and symptom assessment occurred at baseline and at two, four, and eight weeks, or upon symptom worsening as determined by the investigator. Healing was defined as complete re-epithelialization of the crater, without residual erosion. Patients completed eight weeks of treatment regardless of whether or not they were healed at two or four weeks. Treatment groups were comparable with regard to age, sex, ulcer history, cigarette smoking, alcohol and caffeine consumption, ulcer size, and ulcer symptoms. Analysis of procedurally correct cases demonstrated that sucralfate suspension was significantly more effective in healing duodenal ulcers than placebo at two, four, and eight weeks. Ulcer-healing rates efficacy analysis are as follows. At two weeks, the healing rate of sucralfate suspension was 22 of 125 patients (18 percent) and the healing rate of placebo suspension was eight of 130 patients (6 percent; p = 0.006). At four weeks, 58 of 114 patients (51 percent) for sucralfate and 38 of 112 patients (34 percent) for placebo (p = 0.011) were healed. At eight weeks, 80 of 105 (76 percent) for sucralfate and 53 of 100 (53 percent) for placebo (p = 0.001) were healed. Sucralfate-treated patients experienced significantly greater reductions in both daytime and nighttime pain scores at two weeks. A significant difference between treatment groups was also found for daytime symptoms at four weeks. At four and eight weeks, patients who smoked cigarettes had significantly lower healing rates than those who did not, regardless of treatment group. Sucralfate suspension was found to be effective for the treatment of active duodenal ulcer.

Twice-daily dosing with sucralfate was evaluated by two multicenter trials, trial 1 (eight weeks) and trial 2 (four weeks). Both trials demonstrated significantly better ulcer healing at study completion for the 2-g twice daily (B.I.D.) regimen compared with placebo. Both trials were double-blind, randomized, and placebo-controlled, with parallel groups. Patients received two doses daily consisting of sucralfate 2 g B.I.D., placebo/sucralfate 2 g at bedtime (H.S.), or placebo/placebo. Ulcer healing was assessed by scheduled endoscopy and symptom assessment. Healing was defined as complete absence of erosion or ulceration. Trial 1 evaluations were conducted at four and eight weeks, trial 2 evaluations at two and four weeks. Interim examinations were performed at investigator discretion. Treatment groups were comparable with regard to number of patients, age, sex, smoking status, ulcer size, and presence/absence of baseline symptoms. Sucralfate 2 g B.I.D. was significantly better than H.S. or placebo dosing at the completion of each trial. H.S. dosing was better than placebo only at the four-week analysis of trial 1. At Week 4 of trial 1, 14 of 54 patients (26 percent) were healed with the B.I.D. sucralfate regimen, whereas at Week 8, 41 of 54 (76 percent) were healed (p less than 0.001). For the placebo/sucralfate H.S. group, 17 of 57 patients (30 percent) were healed at Week 4 (p less than 0.05), and 32 of 56 patients (57 percent) were healed at Week 8. For the placebo group, six of 52 (12 percent) and 20 of 51 patients (39 percent) were healed at Weeks 4 and 8, respectively. In trial 2, the B.I.D. group had a 21 percent healing rate at Week 2 (13 of 61 patients) and 62 percent were healed at Week 4 (38 of 61 patients; p less than 0.05). The H.S. group had an 8 percent healing rate (five of 66 patients) at Week 2 and 50 percent (33 of 66 patients) at Week 4. For the placebo group, 10 of 62 patients (16 percent) and 26 of 62 patients (42 percent) were healed at Weeks 2 and 4, respectively. Trial 1 demonstrated significant symptom improvement for active treatment groups at both four and eight weeks, whereas no differences were found in trial 2. Sucralfate 2 g B.I.D. was found to be safe and effective for the treatment of acute duodenal ulcer.

Sucralfate 1 g twice daily was found to be significantly better than placebo for the prevention of duodenal ulcer recurrence. This was a double-blind, randomized, placebo-controlled, parallel groups study. A total of 254 patients with a history of two or more duodenal ulcers, the most recent event diagnosed within three months of study entry, were entered into the trial after healing was documented. Patients received sucralfate 1 g twice daily or placebo for four months, or until recurrence. Endoscopies and symptom assessments were scheduled monthly and at investigator discretion upon symptom development. Treatment groups were comparable with regard to number of patients, age, sex, smoking status, and ulcer history. Traditional ulcer prevalence and point prevalence analyses were performed. Traditional ulcer prevalence included all ulcers found at scheduled visits and interim recurrences. Point prevalence included only ulcers found at scheduled visits. In the traditional analysis, sucralfate was significantly better than placebo in reducing ulcer recurrence for all months of the study. The life table estimate of the cumulative percent with ulcer at four months was 42 percent for the sucralfate group and 63 percent for the placebo group (p = 0.002). At four months, there were 49 recurrences among 122 patients in the sucralfate group and 71 among 117 patients for the placebo group. In the point prevalence analysis, sucralfate was significantly better than placebo in reducing ulcer recurrence at Months 2 through 4. The life table estimate of the cumulative percent with ulcer at four months was 36 percent for the sucralfate group and 55 percent for the placebo group (p = 0.005). At four months, there were 38 recurrences among 114 patients in the sucralfate group and 54 among 104 patients for the placebo group. Both analyses demonstrated that sucralfate 1 g twice daily was significantly better than placebo for the prevention of duodenal ulcer recurrence. Symptom development was associated with recurrence in both treatment groups. Smoking was associated with a greater tendency to recur in placebo-treated patients only.

In a randomized trial involving 20 Italian centers, the effectiveness of 1 g sucralfate three times a day and 150 mg ranitidine twice a day in the treatment of chronic gastritis was assessed and compared. Five hundred outpatients with dyspeptic symptoms and endoscopic evidence of chronic nonerosive gastritis were randomly assigned to either treatment for a period of eight weeks. Endoscopic scores were determined at the beginning and at the end of the study. The severity of dyspeptic symptoms was assessed at Weeks 0, 2, 4, 6, and 8. Four hundred seventy-three patients completed the study. In 331 cases, biopsies were taken during endoscopy, and a histologic evaluation was also performed, according to Whitehead's criteria. Sucralfate was significantly more effective than ranitidine in inducing healing or improvement of both endoscopic (p less than 0.02) and histologic (p less than 0.001) features. At the end of the study, 77.6 percent of the patients in the sucralfate group and 79.4 percent in the ranitidine group were symptom free. Ranitidine was significantly more efficacious at releiving pain during the first four weeks of therapy. Mild side effects were reported by 4.9 percent of patients treated with sucralfate and by 3.6 percent of patients treated with ranitidine. Treatment was withdrawn in one patient treated with sucralfate because of nausea. In conclusion, sucralfate appears significantly superior to ranitidine in improving endoscopic and histologic aspects of chronic nonerosive gastritis. The symptomatic activity of the two drugs is similar, although more rapid relief is obtained with ranitidine.

Sucralfate was evaluated in several clinical studies on reflux esophagitis, a total of over 400 patients were studied worldwide. In this study 49 patients with reflux esophagitis of stage I-III acc. to Savary and Miller were included. The evaluation was based on 41 patients, 22 received sucralfate suspension 1 g in 5 ml qid, 19 ranitidine 150 mg bid. The patients were treated for 8 weeks, endoscopic controls were performed before treatment and after 8 weeks. The healing rates were 64% in the sucralfate group and 68% in the ranitidine group and exhibited no significant difference (p greater than 0.05). Antacid consumption and symptomatic improvement were comparable in both groups. Sucralfate seems to be a valid alternative to H2-blockers in the treatment of reflux esophagitis.

Sucralfate is known for its gastroprotective properties in humans and rats, but the importance of intragastric pH in this protection is a subject of controversy. This study, performed on healthy young volunteers and rats, was designed to compare the gastroprotective effects of sucralfate with those of sucralfate combined with ranitidine or of sucralfate adjusted to pHs varying from 1 to 7. In humans the mucosal damage induced by 40% ethanol spray after 4 days of pretreatment with placebo, sucralfate (1 g four times daily), ranitidine (150 mg three times daily), or the combination of sucralfate plus ranitidine was evaluated by means of endoscopy with mucosal biopsy and histologic examination. Sucralfate alone reduced the endoscopic score significantly (compared with placebo) and prevented deep necrotic lesions. Neither ranitidine alone nor its combination with sucralfate prevented ethanol-induced endoscopic and histologic mucosal changes. In rats acute gastric lesions were induced by 100% ethanol. Sucralfate was relatively more effective in mucosal protection against ethanol when given at lower pH (1 or 2) than at original pH (4.5) and failed to protect at neutral pH (7.0). Pretreatment with ranitidine, which by itself did not change ethanol damage, greatly reduced the protection afforded by sucralfate. We conclude that sucralfate protects the gastric mucosa against ethanol damage both in humans and in rats and that this protection is dependent on the presence of an acidic intragastric pH.

Inhibition of gastric acid secretion is a major factor in protecting the gastric mucosa, although other mechanisms such as bile salt binding may contribute to the protective properties of individual agents. Sucralfate, antacid (Maalox), and Meciadanol, a new flavonoid, were compared with cholestyramine resin for binding bile salts. The free, glycine, and taurine conjugates of the human bile salts, cholate, chenodeoxycholate, and deoxycholate, were incubated with each of the above. Cholestyramine resin adsorbed 91-97% of all bile salts tested. Meciadanol adsorbed all of the bile salts fairly well except for the free forms of chenodeoxycholate and deoxycholate. Meciadanol (53 to 84%) adsorbed bile salts better than sucralfate (4.2 to 61%), and significantly (P less than 0.05) better than Maalox (10 to 47%). In our in vitro studies, sucralfate was not as effective in binding bile salts as previously reported. Patients in the surgical intensive care unit were randomized prospectively to receive nasogastric instillation of Maalox, sucralfate, or Meciadanol to prevent gastrointestinal bleeding. The gastric aspirates were analyzed for bile salt concentration. The mean bile salt concentration of those treated with Maalox (0.24 mM), Meciadanol (0.24 mM), or sucralfate (0.35 mM) was significantly lower than those treated with nasogastric aspiration (0.87 mM) alone (P less than 0.01). This suggests that these substances bind bile salts and may provide additional protection to the gastric mucosa along with their ability to neutralize gastric acid.

Sucralfate is well established in the treatment of upper gastrointestinal inflammation and ulceration, and preliminary evidence suggests it may be of benefit in active colitis. We have therefore undertaken a clinical trial to compare enemas of sucralfate (4 g) and prednisolone metasulphobenzoate (20 mg) in the treatment of active distal ulcerative colitis. Forty-four patients were entered into a 4-week study. Two patients were withdrawn because of non-compliance, and five were unable to complete the study: two developed constipation (both allocated to sucralfate) and three were unable to retain the enemas (two prednisolone and one sucralfate). Intention-to-treat analysis showed significant within-treatment improvement in rectal bleeding, sigmoidoscopic grade, and histologic grade in the prednisolone-treated group, and in stool frequency, rectal bleeding, and sigmoidoscopic grade in the sucralfate-treated group. Between-treatment comparisons, however, showed greater resolution of rectal bleeding and more marked improvements in histologic grade in patients treated with prednisolone metasulphobenzoate enemas. Further studies using higher doses of sucralfate would be useful.

Aphthous ulcers are common, painful lesions that affect the oral mucosa and for which no successful treatment has been found. Sucralfate, which acts by locally binding with the proteins at the base of an ulcer to provide a protective covering, has been suggested as a treatment for aphthous ulcers. Forty-five subjects with active aphthous ulcers were recruited into this double-blind study designed to compare treatment of aphthous ulcers using sucralfate or placebo in a powdered spray. Measures of ulcer diameter and area were recorded before and after four days of treatment and the subjects completed a daily log measuring subjective response to the treatment. Sucralfate, as used in this study, was not found to be effective in the treatment of aphthous ulcers.

Ten cases of gastroduodenal inflammation were diagnosed by endoscopy among a series of 196 children with evidence of Crohn's disease involving other regions of the intestinal tract. Endoscopic and histologic confirmation of upper gastrointestinal tract involvement was performed only in those cases with suggestive symptoms. The mean age at presentation in the 10 cases with gastroduodenal inflammation was 14.6 +/- 1.9 (+/- SD) years, with involvement identified at the time of initial diagnosis of Crohn's disease in five of the 10. Eight of 10 cases occurred in boys. The major presenting symptoms were weight loss in five cases, epigastric pain in three, and recurrent vomiting in two. Hematemesis and melena occurred in only one of the 10 cases. Endoscopic and histological evidence of mucosal inflammation was seen in all 10 cases. Three of 10 cases had noncaseating granuloma present in biopsies of the stomach or duodenum. Two cases also had endoscopic and histological evidence of esophageal involvement. All cases were initially treated with oral corticosteroids, and in each instance a good clinical response was noted. Sucralfate (n = 1), 6-mercaptopurine (n = 1), and H2 receptor antagonists (n = 3) were used as adjunct therapy. After follow-up for 2.7 years (range, 0.5-5.5 years), none of the 10 cases required surgical intervention. Therefore, at least in the short-term, the outlook for adolescents with gastroduodenal Crohn's disease appears to be good and their medical management need not differ from those patients with Crohn's disease involving only more distal portions of the small intestine.
