Ursocol (Ursodeoxycholic Acid): An Anti-Gallstone and Hepatoprotective Agent

Ursocol contains Ursodeoxycholic Acid, a naturally occurring bile acid. It is indicated for the treatment of various hepatobiliary disorders, including cholestasis (jaundice), viral hepatitis, alcoholic fatty liver, and primary biliary cirrhosis (PBC). It is also used to reduce the cholesterol saturation of bile to promote the dissolution of gallstones and to treat Primary Sclerosing Cholangitis (PSC) and Non-Alcoholic Steato Hepatitis (NASH). Ursocol belongs to the therapeutic class of anti-gallstone drugs and bile acids.

How Ursocol Works (Pharmacology)

Ursodeoxycholic Acid's activity is multifaceted, primarily working to alter bile composition and protect liver cells:

• Reduces Cholesterol in Bile: It reduces the secretion of cholesterol into bile by decreasing cholesterol absorption and suppressing liver cholesterol synthesis. This changes bile composition from supersaturated to unsaturated, allowing cholesterol gallstones to gradually dissolve.
• Promotes Gallstone Dissolution: It facilitates the formation of liquid cholesterol crystal complexes, which helps remove cholesterol from the gallbladder.
• Hepatoprotective Action: It improves cholestatic liver diseases by:
  • Protecting liver cells (cholangiocytes and hepatocytes) from the toxic effects of other bile acids.
  • Stimulating hepatobiliary secretion.
  • Protecting hepatocytes against bile acid-induced apoptosis (cell death).

Key Indications & Benefits

Ursocol is indicated for the treatment of:

• Cholestasis (Jaundice)
• Viral Hepatitis
• Alcoholic Fatty Liver
• Primary Biliary Cirrhosis (PBC)
• Primary Sclerosing Cholangitis (PSC)
• Dissolution of Gallstones
• Non-Alcoholic Steato Hepatitis (NASH)

Dosage & Administration

The dosage of Ursocol is based on the condition being treated and the patient's weight. Always consult a registered physician for specific dosage instructions.

• Dissolution of Gallstones: 8-12 mg/kg/day, as a single nighttime dose or in divided doses.
• Primary Biliary Cirrhosis: 10-15 mg/kg/day, in 2-4 divided doses.
• Acute Viral Hepatitis: 600 mg/day.
• Alcoholic Fatty Liver: 300 mg/day.
• Primary Sclerosing Cholangitis: 25-30 mg/kg/day.
• Non-Alcoholic Steato Hepatitis: 13-15 mg/kg/day.

Important Considerations & Warnings

It is crucial to discuss your full medical history with your doctor before taking Ursocol.

Contraindications:

• Non-functioning gall-bladder.
• Calcified and pigmented gallstones.
• Inflammatory bowel disease.

Side Effects:

• Commonly reported: Nausea, vomiting, diarrhea, pruritus (itching), and gallstone opacification.

Pregnancy & Lactation:

• Pregnancy: Ursocol is classified as Pregnancy Category B. There is no evidence of harm during pregnancy, and it has been used to treat cholestasis of pregnancy.
• Lactation: Problems have not been documented in humans regarding breastfeeding.

Precautions & Warnings:

• Use with caution in patients with liver disease.

Drug Interactions:

• Estrogenic hormones: Should not be used with drugs that increase bile cholesterol, such as estrogenic hormones.
• Bile-acid binding drugs: Concomitant administration with drugs like antacids, charcoal, or cholestyramine should be avoided, as they can reduce the effectiveness of Ursocol.

Storage Conditions

Store below 25°C, protected from light and moisture. Keep out of the reach of children.
