Ursodeoxycholic acid
Ursodeoxycholic acid is an epimer of chenodeoxycholic acid (DB06777). It is a mammalian bile acid found first in the bear and is apparently either a precursor or a product of chenodeoxycholate. Its administration changes the composition of bile and may dissolve gallstones. It is used as a cholagogue and choleretic. [PubChem] Indication: The drug reduces cholesterol absorption and is used to dis...
متن کاملUrsodeoxycholic acid complexation with 2-hydroxypropyl-beta-cyclodextrin increases ursodeoxycholic acid biliary excretion after single oral administration in rats.
Complexation of ursodeoxycholic acid (UDCA) with 2-hydroxypropyl-beta-cyclodextrin (HPbetaCD) improves the water solubility and the dissolution rate of UDCA and may therefore increase its bioavailability. We compared the amount and the rate of biliary excretion of UDCA and biliary lipid secretion after a single oral administration of UDCA in 3 different pharmaceutical formulations [UDCA-HPbetaC...
متن کاملMolecular Mechanisms of Ursodeoxycholic Acid Toxicity & Side Effects: Ursodeoxycholic Acid Freezes Regeneration & Induces Hibernation Mode
Ursodeoxycholic acid (UDCA) is a steroid bile acid approved for primary biliary cirrhosis (PBC). UDCA is reported to have "hepato-protective properties". Yet, UDCA has "unanticipated" toxicity, pronounced by more than double number of deaths, and eligibility for liver transplantation compared to the control group in 28 mg/kg/day in primary sclerosing cholangitis, necessitating trial halt in Nor...
متن کاملRadioimmunoassay of ursodeoxycholic acid in serum.
A sensitivie and specific radioimmunoassay for the measurement of serum ursodeoxycholic acid has been developed. Ursodeoxycholic acid bound to bovine serum albumin was used as an antigen, and antiserum to this antigen was raised in the rabbit. [11, 12-3h2]Ursodeoxycholic acid was used as the radioactive tracer, and the radioimmunoassay was carried out by the method of Simmonds et al. (1973. Gas...
متن کاملClinical Study of Ursodeoxycholic Acid in Barrett's Esophagus Patients.
Prior research strongly implicates gastric acid and bile acids, two major components of the gastroesophageal refluxate, in the development of Barrett's esophagus and its pathogenesis. Ursodeoxycholic acid (UDCA), a hydrophilic bile acid, has been shown to protect esophageal cells against oxidative stress induced by cytotoxic bile acids. We conducted a pilot clinical study to evaluate the clinic...
