DESCRIPTION
Sucron is an α-D-glucopyranoside, β-D-fructofuranosyl-, octakis(hydrogen sulfate), aluminum complex.
R = SO Al(OH) 3 2
Tablets for oral administration contain 1 g of Sucron.
CLINICAL PHARMACOLOGY
Sucron is only minimally absorbed from the gastrointestinal tract. The small amounts of the sulfated disaccharide that are absorbed are excreted primarily in the urine.
Although the mechanism of sucralfate’s ability to accelerate healing of duodenal ulcers remains to be fully defined, it is known that it exerts its effect through a local, rather than systemic, action. The following observations also appear pertinent:
- Studies in human subjects and with animal models of ulcer disease have shown that Sucron forms an ulcer-adherent complex with proteinaceous exudate at the ulcer site.
- , a sucralfate-albumin film provides a barrier to diffusion of hydrogen ions. In vitro
- In human subjects, Sucron given in doses recommended for ulcer therapy inhibits pepsin activity in gastric juice by 32%.
- , Sucron absorbs bile salts. In vitro
These observations suggest that sucralfate’s antiulcer activity is the result of formation of an ulcer-adherent complex that covers the ulcer site and protects it against further attack by acid, pepsin, and bile salts. There are approximately 14 to 16 mEq of acid-neutralizing capacity per 1 g dose of Sucron.
CLINICAL TRIALS
INDICATIONS AND USAGE
Sucron is indicated in:
- Short-term treatment (up to 8 weeks) of active duodenal ulcer. While healing with Sucron may occur during the first week or two, treatment should be continued for 4 to 8 weeks unless healing has been demonstrated by x-ray or endoscopic examination.
- Maintenance therapy for duodenal ulcer patients at reduced dosage after healing of acute ulcers.
CONTRAINDICATIONS
There are no known contraindications to the use of Sucron.
PRECAUTIONS
Duodenal ulcer is a chronic, recurrent disease. While short-term treatment with Sucron can result in complete healing of the ulcer, a successful course of treatment with Sucron should not be expected to alter the posthealing frequency or severity of duodenal ulceration.
Special Populations
Drug Interactions
Some studies have shown that simultaneous Sucron administration in healthy volunteers reduced the extent of absorption of single doses of the following: cimetidine, digoxin, fluoroquinolone antibiotics, ketoconazole, l-thyroxine, phenytoin, quinidine, ranitidine, tetracycline, and theophylline. Subtherapeutic prothrombin times with concomitant warfarin and Sucron therapy have been reported in spontaneous and published case reports. However, two clinical studies have demonstrated no change in either serum warfarin concentration or prothrombin time with the addition of Sucron to chronic warfarin therapy.
The mechanism of these interactions appears to be nonsystemic in nature, presumably resulting from Sucron binding to the concomitant agent in the gastrointestinal tract. In all case studies to date (cimetidine, ciprofloxacin, digoxin, norfloxacin, ofloxacin, and ranitidine), dosing the concomitant medication 2 hours before Sucron eliminated the interaction. Because of the potential of Sucron to alter the absorption of some drugs, Sucron should be administered separately from other drugs when alterations in bioavailability are felt to be critical. In these cases, patients should be monitored appropriately.
Carcinogenesis, Mutagenesis, Impairment of Fertility
Chronic oral toxicity studies of 24 months’ duration were conducted in mice and rats at doses up to 1 g/kg (12 times the human dose).
There was no evidence of drug-related tumorigenicity. A reproduction study in rats at doses up to 38 times the human dose did not reveal any indication of fertility impairment. Mutagenicity studies were not conducted.
Pregnancy
Teratogenic Effects
Nursing Mothers
It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when Sucron is administered to a nursing woman.
Pediatric Use
Safety and effectiveness in pediatric patients have not been established.
Geriatric Use
Clinical studies of Sucron tablets did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy. DOSAGE AND ADMINISTRATION
This drug is known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function.

ADVERSE REACTIONS
Adverse reactions to Sucron in clinical trials were minor and only rarely led to discontinuation of the drug. In studies involving over 2700 patients treated with Sucron tablets, adverse effects were reported in 129 (4.7%).
Constipation was the most frequent complaint (2%). Other adverse effects reported in less than 0.5% of the patients are listed below by body system:
OVERDOSAGE
Due to limited experience in humans with overdosage of Sucron, no specific treatment recommendations can be given. Acute oral toxicity studies in animals, however, using doses up to 12 g/kg body weight, could not find a lethal dose. Sucron is only minimally absorbed from the gastrointestinal tract. Risks associated with acute overdosage should, therefore, be minimal. In rare reports describing Sucron overdose, most patients remained asymptomatic. Those few reports where adverse events were described included symptoms of dyspepsia, abdominal pain, nausea, and vomiting.
