Tương tác
May decrease the absorption of digoxin, quinidine, fluoroquinolones, tetracycline, ketoconazole, sulpiride, levothyroxine, phenytoin, ranitidine, cimetidine, warfarin and theophylline; consider dosing interval of at least 2 hours between sucralfate and other concomitant non-antacid drugs. May increase the total body burden of Al when concomitantly used with other preparation that contains Al (e.g. Al-containing antacids). If antacids are concurrently needed, a dosing interval of 30 minutes between sucralfate and antacids is recommended.
Tác dụng
Description: Sucralfate is a basic, Al complex of sucrose octasulfate. It binds with positively charged protein exudates at the ulcer site, forming a viscous paste-like ulcer-adherent complex. This complex acts as a protective barrier on the gastric lining against pepsin, peptic acid and bile salts. It also inhibits pepsin activity.
Onset: 1-2 hours.
Pharmacokinetics:
Absorption: Minimally absorbed from the gastrointestinal tract (as sucrose sulfate). Small amounts of Al may be absorbed after sucralfate administration.
Distribution: Locally acts to ulcer sites; unbound in the gastrointestinal tract to Al and sucrose octasulfate.
Excretion: Mainly via urine (small amounts of sulfated disaccharide).
