Sucralfate

Clinical summary

Indications and usage INDICATIONS AND USAGE Sucralfate Oral Suspension is indicated in the short-term (up to 8 weeks) treatment of active duodenal ulcer. Dosage and administration DOSAGE AND ADMINISTRATION Active Duodenal Ulcer: The recommended adult oral dosage for duodenal ulcer is 1 gram (10 mL) four times per day. Sucralfate Oral Suspension should be administered on an empty stomach. Antacids may be prescribed as needed for relief of pain but should not be taken within one-half hour before or after Sucralfate Oral Suspension. While healing with sucralfate 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. Elderly: 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 (see PRECAUTIONS Geriatric Use ). Call your doctor for medical advice about side effects. You may report side effects to Amneal Pharmaceuticals at 1-877-835-5472 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. Warnings and cautions WARNINGS Fatal complications, including pulmonary and cerebral emboli have occurred with inappropriate intravenous administration of Sucralfate Oral Suspension. Administer Sucralfate Oral Suspension only by the oral route. Do not administer intravenously. Drug interactions Drug Interactions Some studies have shown that simultaneous sucralfate administration in healthy volunteers reduced the extent of absorption (bioavailability) 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 sucralfate 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 sucralfate to chronic warfarin therapy. The mechanism of these interactions appears to be nonsystemic in nature, presumably resulting from sucralfate binding to the concomitant agent in the gastrointestinal tract. In all cases studied to date (cimetidine, ciprofloxacin, digoxin, norfloxacin, ofloxacin, and ranitidine), dosing the concomitant medication 2 hours before sucralfate eliminated the interaction. Due to Sucralfate Oral Suspension's potential to alter the absorption of some drugs, Sucralfate Oral Suspension should be administered separately from other drugs when alterations in bioavailability are felt to be critical. In these cases, patients should be monitored appropriately. Pregnancy Pregnancy Teratogenic effects. Teratogenicity studies have been performed in mice, rats, and rabbits at doses up to 50 times the human dose and have revealed no evidence of harm to the fetus due to sucralfate. There are, however, no adequate and well-controlled studies in pregnant women. Because animal reproduction studies are not always predictive of human response, this drug should be used during pregnancy only if clearly needed.
