UDCHOLIC 150

Ursodeoxycholic Acid 150mg is a to break down small cholesterol gallstones when surgery isn't an option. It works by altering the composition of bile, making it less likely to form stones, and by protecting liver cells from bile acid–induced damage. It is typically taken with food, once or in divided doses as prescribed, and treatment often continues for several months depending on the condition being treated. Common side effects include mild diarrhea, nausea, and stomach upset. 

What Is Ursodeoxycholic Acid 150mg?

Ursodeoxycholic Acid (UDCA) 150mg is a synthetic bile acid, chemically similar to a naturally occurring bile acid produced in small amounts by the human liver. Unlike many other bile acids that can be harmful to liver cells in excess, ursodeoxycholic acid is considered hepatoprotective — meaning it helps shield liver tissue from damage while simultaneously improving the flow and composition of bile.

The 150mg strength is commonly prescribed for patients who need a lower or titratable dose, often used in combination regimens, in pediatric or lower-body-weight adults, or as a starting dose before escalation to higher strengths such as 300mg. It is manufactured under WHO-GMP and ISO-certified conditions to ensure consistent potency and safety across batches.

Key Clinical Indications

Condition	How Ursodeoxycholic Acid Helps
Cholesterol gallstones (small, radiolucent)	Dissolves stones by reducing cholesterol saturation in bile
Primary Biliary Cholangitis (PBC)	Slows disease progression, improves liver enzyme levels
Chronic hepatitis / fatty liver conditions	Adjunct therapy to reduce liver enzyme elevation
Post-bariatric surgery gallstone prevention	Prophylactic use to prevent gallstone formation
Biliary reflux gastritis	Reduces bile-related irritation of the stomach lining

Mechanism of Action

Ursodeoxycholic acid works through several complementary pathways:

1. Cholesterol desaturation – It reduces the cholesterol content of bile relative to bile acids and phospholipids, shifting the balance so that cholesterol crystals are less likely to form and existing small stones can gradually dissolve.
2. Cytoprotection – It replaces more toxic, hydrophobic bile acids in the bile acid pool with a milder, more hydrophilic molecule, reducing injury to liver cell membranes.
3. Immunomodulation – In conditions like PBC, it is believed to reduce the expression of certain immune-related molecules on bile duct cells, dampening inflammatory damage.
4. Choleretic effect – It stimulates bile flow (choleresis), which helps clear potentially toxic substances from the liver more efficiently.

Together, these actions make ursodeoxycholic acid useful both for dissolving certain stones and for slowing the progression of chronic cholestatic liver diseases.

Dosage Guidelines

Dosage of ursodeoxycholic acid 150mg is individualized based on body weight, the condition being treated, and physician judgment. General patterns include:

• Gallstone dissolution: Often dosed according to body weight, taken in divided doses with meals, continued for several months with periodic ultrasound monitoring.
• Primary Biliary Cholangitis: Typically a weight-based daily dose, taken in divided doses with food, as a long-term maintenance therapy.
• General liver support / adjunct use: Lower maintenance doses as directed by the prescribing doctor.

Tablets are generally best taken with food to improve absorption and reduce gastrointestinal discomfort. Missed doses should not be doubled up; patients should follow the schedule advised by their physician.

Key Benefits

• Non-surgical option for dissolving small cholesterol gallstones
• Slows progression of chronic cholestatic liver disease
• Generally well tolerated for long-term use compared to many other liver-directed therapies
• May improve liver enzyme markers over time in appropriate candidates
• Available in a lower 150mg strength suitable for titration or combination regimens

Side Effects

Most patients tolerate ursodeoxycholic acid well, but side effects can occur. These are generally categorized as follows:

Common (mild):

• Diarrhea or loose stools
• Nausea
• Mild abdominal discomfort or bloating

Less common:

• Constipation
• Headache
• Skin itching or mild rash

Rare but requiring medical attention:

• Signs of worsening liver function (yellowing of skin/eyes, dark urine, severe abdominal pain)
• Severe allergic reaction (swelling, difficulty breathing, hives)

Substitutes / Comparable Bile Acid Therapies

Composition	Typical Use Case	Notes
Ursodeoxycholic Acid 150mg	Lower/titratable dosing, combination regimens	This product
Ursodeoxycholic Acid 300mg	Standard adult maintenance dosing	Higher strength, same mechanism
Ursodeoxycholic Acid 450mg	Higher-weight patients, once-daily convenience	Fewer daily tablets needed
Obeticholic acid	Second-line PBC therapy	Used when UDCA response is inadequate

Precautions

• Not recommended for patients with calcified gallstones, gallbladder that does not function on imaging tests, or acute cholecystitis.
• Use with caution in patients with severe liver impairment; regular liver function monitoring is advised during treatment.
• Inform your doctor of all other medications, as certain drugs (e.g., cholesterol-binding resins, some antacids) can reduce absorption if taken too close together.
• Pregnancy and breastfeeding: use only if clearly advised by a physician after weighing risks and benefits.
• Periodic gallbladder ultrasound monitoring is typically recommended during gallstone dissolution therapy to track treatment response.

Conclusion

Ursodeoxycholic Acid 150mg is a well-established bile acid therapy used to dissolve small cholesterol gallstones and manage chronic cholestatic liver conditions such as primary biliary cholangitis. Its dual action of desaturating cholesterol in bile and protecting liver cells makes it a valuable option for patients seeking a non-surgical, long-term management approach. While generally well tolerated, side effects and treatment duration should always be discussed with a qualified doctor, and regular monitoring is essential for the best outcomes. Prescription only – consult your doctor to determine if this medication is right for your condition.
