BISMUTH

Written by

Various bismuth chelates and complexes, such as sucralfate, effective in healing gastric and duodenal ulcers are available. They may act by a direct toxic effect on gastric HELICOBACTER PYLORI, or by stimulating mucosal prostaglandin (see PROSTAGLANDINS) or bicarbonate secretion. Healing tends to be longer than with H2-RECEPTOR ANTAGONISTS and relapse still occurs. New regimens are being developed involving co-administration with antibiotics. ENCEPHALOPATHY, described with older high-dose bismuth preparations, has not been reported.
