CHENODIOL vs URSO FORTE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Chenodiol is a bile acid that reduces cholesterol saturation in bile by suppressing hepatic synthesis of cholesterol and inhibiting intestinal absorption of cholesterol. It also expands the bile acid pool and decreases biliary cholesterol secretion, promoting dissolution of cholesterol gallstones.
Ursodeoxycholic acid (UDCA) is a hydrophilic bile acid that reduces the concentration of hydrophobic bile acids in bile, thereby decreasing hepatocyte injury. It also has immunomodulatory effects, including inhibition of apoptosis and stimulation of bile flow.
13-15 mg/kg/day orally in 2-4 divided doses, typically starting at 250 mg twice daily, then increasing by 250 mg/day every 1-2 weeks to full dose.
13-15 mg/kg/day orally in 2-4 divided doses for primary biliary cholangitis; for gallstone dissolution, 8-10 mg/kg/day in 2-3 divided doses.

Terminal elimination half-life: 3-5 days. Clinical context: Prolonged due to enterohepatic recycling; steady-state achieved in 3-4 weeks.
Terminal elimination half-life of ursodeoxycholic acid is approximately 3.5–5.8 days (range due to enterohepatic cycling). Clinically, this long half-life supports once-daily dosing and reflects slow turnover in the bile acid pool.
Primarily biliary (renal excretion minimal; <1% unchanged in urine). Fecal excretion as metabolites.
Biliary (primary); renal (<1% as unchanged drug). Ursodeoxycholic acid undergoes extensive hepatic conjugation and enterohepatic circulation; fecal elimination of metabolites and minor amounts of parent drug.
