Carafate - Pharmacology:

Although sucralfate's mechanism is not entirely understood, there are several factors that most likely contribute to its action. Carafate, with its strong negative charge, binds to exposed positively-charged proteins at the base of ulcers. In this way, it coats the ulcer and forms a physical barrier that protects the ulcer surface from further injury by acid and pepsin. It directly inhibits pepsin (an enzyme that breaks apart proteins) in the presence of stomach acid and binds bile salts coming from the liver via the bile thus protecting the stomach lining from injury caused by the bile acids. Carafate may increase prostaglandin production, and prostaglandins are known to protect the lining of the stomach and may also bind epithelial growth factor and fibroblast growth factor, both of which enhance the growth and repair mechanism of the stomach lining.

Carafate 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. Because of the potential of CARAFATE to alter the absorption of some drugs, CARAFATE should be administered separately from other drugs when alterations in bioavailability are felt to be critical. In these cases, patients should be monitored appropriately.
