USOSAN Ursodeoxycholic Acid 200mg Tablet 1's
Indications/Uses
Dosage/Direction for Use
Dosage may be adjusted depending on the patient's age or symptoms. Or as prescribed by the physician.
Overdosage
Administration
Contraindications
Patients with severe liver diseases.
Patients with radio-opaque calcified gallstones.
Patients with non-functioning gall bladder.
Patients with acute cholecystitis.
Special Precautions
Patients with peptic ulcer.
Patients who have gallstones in bile duct.
Serum hepatic enzyme level should be monitored periodically during therapy. Although severe adverse reaction following overdosage is not likely to happen, hepatic function test should be performed if necessary.
Use in Children: Cholesterol-rich gallstones are rare in children but when they occur, dosage should be related to bodyweight.
Use in Elderly: There is no evidence to suggest that any alteration in the adult dose is needed but the relevant precautions should be taken into account.
Use In Pregnancy & Lactation
Adverse Reactions
Hypersensitivity: Occasionally pruritus, and rarely eruption may occur.
Others:Rarely malaise, dizziness, calcified gall bladder, and increased GOT, GPT, and γ-GTP level may occur.
Drug Interactions
In vitro study has shown that cholestyramine, colestipol, charcoal, and certain antacids containing aluminum hydroxide decrease the absorption of the drug.
Drugs known to increase cholesterol elimination in bile, such as estrogen-containing oral contraceptives, and certain blood cholesterol lowering agents, such as clofibrate, should not be prescribed concomitantly.
Storage
Action
Pharmacokinetics: Intestinal absorption after an oral dose of ursodeoxycholic acid is high, with a first-pass clearance of about 50 to 60%. Studies show that passive diffusion occurs, whereupon the drug enters the enterohepatic circulation and is subject to an efficient hepatic extraction mechanism. The 'spillover' into the systemic blood supply is therefore minimal. Plasma levels are not clinically important but may be useful in estimating patient compliance; they reach maximum concentrations at about 60 minutes after ingestion with another peak recorded at 3 hours.
Ursodeoxycholic acid is rapidly conjugated with glycine and taurine in the liver. Microbial biotransformation of the drug and its metabolites occurs when they leave the enterohepatic circulation and is responsible for high levels of faecal lithocholic and 7-ketolithocholic acids during ursodeoxycholic acid therapy. Intestinal flora also hydrolyse conjugated drug back to the parent compound and interconvert ursodeoxycholic and chenodeoxycholic acids.
