Ursodeoxycholic Acid: Dosage, Uses & Side Effects

Ursodeoxycholic acid (UDCA) is a bile acid widely used to treat various liver and gallbladder disorders. This article will delve into its benefits, uses, and potential side effects, with a particular focus on its mechanism of action and applications in different conditions.

What is Ursodeoxycholic Acid?

Ursodeoxycholic acid tablet, also known as UDCA, is a secondary bile acid derived from cholesterol. It is primarily used to treat gallstones and certain liver diseases. Available in various forms, including tablets and syrups, UDCA is recognised for its ability to enhance bile flow and lower cholesterol saturation in bile.

Ursodeoxycholic acid (UDCA) is a secondary bile acid derived from cholesterol, primarily used to treat liver and gallbladder disorders. Ursodeoxycholic acid tablet use includes dissolving cholesterol gallstones, managing primary biliary cholangitis (PBC), and treating bile reflux.

Mechanism of Action

The primary mechanism of action of ursodeoxycholic acid involves its ability to reduce the cholesterol content in bile. This is achieved through several pathways:

Cholesterol Solubilization: UDCA enhances the solubilization of cholesterol in bile, thereby preventing the formation of cholesterol gallstones.
Cytoprotective Effect: It stabilises the membranes of hepatocytes and cholangiocytes, which contributes to its protective effect on the liver.
Immunomodulation: UDCA has been shown to modulate immune responses, particularly in autoimmune liver diseases like primary biliary cholangitis (PBC).

Ursodeoxycholic Acid Tablet Uses

Ursodeoxycholic Acid 300 mg Uses

UDCA 300 mg tablets are commonly prescribed for the following conditions:

Gallstone Dissolution: It is effective in dissolving small cholesterol gallstones in patients who prefer a non-surgical approach.
Primary Biliary Cholangitis (PBC): UDCA is the first-line treatment for PBC, a chronic liver disease characterised by the destruction of bile ducts.
Bile Reflux: It can alleviate symptoms of bile reflux, a condition where bile flows back into the stomach and esophagus.

Ursodeoxycholic Acid in Pregnancy

UDCA is also used to manage intrahepatic cholestasis of pregnancy (ICP), a liver disorder that occurs during pregnancy. It improves bile flow and reduces itching, a common symptom of ICP.

Ursodeoxycholic Acid Side Effects

While ursodeoxycholic acid is generally well-tolerated, it may cause some side effects, including:

Diarrhea: This is the most common side effect and can often be managed by adjusting the dose.
Nausea: Some patients may experience mild nausea.
Allergic Reactions: Although rare, allergic reactions such as rash or hives can occur.

While generally safe, UDCA can cause:

Common: Diarrhea, mild nausea, stomach discomfort.
Less Common: Headache, rash, or dizziness.
Rare: Severe allergic reactions or elevated liver enzymes.

If any severe symptoms appear, consult your doctor immediately.

Ursodeoxycholic Acid Dosage and Administration

The dosage of UDCA varies depending on the condition being treated. For gallstone dissolution, It is crucial to follow the prescribed dosage to achieve optimal results.

Gallstone Dissolution: 8–10 mg/kg/day (often using Ursocol 300 tablets).
PBC Treatment: 13–15 mg/kg/day.
Take with meals for better absorption.
Therapy may last months to years depending on the condition.
