  • Drug Interactions (1) In combination with chenodeoxycholic acid, the effect of promoting cholesterol level and de-saturation in bile were more than single drugs. The effect is also greater than that of the sum of the two drugs. (2) This product is not suitable taken together with cholestyramine or antacids containing aluminum hydroxide for not affecting the absorption. (3) Oral contraceptives may affect the efficacy of the product.
  • Uses Ursodeoxycholic acid is a naturally occurring bile salt in humans. It is rapidly absorbed in the small intestine and excreted with the bile. Ursodeoxycholic acid is the drug of choise for the treatment of primary biliary cirrhosis and primary sclerosis cholanyitis. The daily dose amounts to 10-15 mg/kg. It has no side effects even after a treatment period of up to 20 years.Dissolution of gallstones. Mainly used for the treatment of inoperable cholesterol gallstones, it will have a cure rate especially in the case when gallbladder is basically normal, stones have a 15mm or lower diameters, X-ray penetrable, non-calcified and high-floating cholesterol stones.Ursodeoxycholic acid can also improve the efficacy of α-interferon on treatment of chronic hepatitis C. It can also used to treat diarrhea, rare constipation, allergic reactions, itching, headache, dizziness, stomach pain, pancreatitis and bradycardia Patients of completely biliary obstruction or severe liver dysfunction and pregnant women should avoid using. Ursodeoxycholic acid (UDCS) is a cell protectant used extensively to mitigate hepatic and biliary diseases. Ursodeoxycholic acid may be used to study its specific activities that range from reduction of cholesterol absorpition, cholesterol gallstone dissolution to suppression of immune response. It is also used as an anticholelithogenic. Epimer with Chenodiol with respect to the hydroxyl group at C7.
  • Production method Method 1: Use chenodeoxycholic acid as raw materials Preparation of 3α, 7α-diacetyl cholic acid methyl ester; Take 36ml of anhydrous methanol, and pass through 1g dried hydrogen chloride gas, add bile acid 12g, stir, heat and reflux for 20-30min. After standing for several hours at room temperature when crystals are separated out, freeze, filter, wash with ether, and dry to obtain methyl cholate. Take 2g methyl cholate, add 9.6 mL of benzene, 2.4mL pyridine, 2.4 mL of acetic anhydride, shake for 10-15min, stand for 20h at room temperature, then pour the reaction mixture into 100ml of water, remove the benzene layer, repeatedly wash with distilled water before recycling the solvents. Wash the solid residue with petroleum ether once, and re-crystallize with methanol-aqueous solution to obtain 3α, 7α-diacetyl bile acid methyl ester. Bile acid methyl → → 3α, 7α-diacetyl bile acid methyl ester Preparation of Chenodeoxycholic acid: Take the 1.5 g diacetyl bile acid methyl ester, add 24 mL acetic acid, add potassium chromate solution (Take 0.76g potassium chromate to dissolve it in 1.8ml take in water), heated to 40 °C, perform reaction for 8h, add water 120ml, shaking for some moment, placed 12h, filter, wash with distilled water till neutralization, dry to give 3α, 7α-diacetoxy-12-keto bile acid methyl ester, referred briefly as the 12-ketone. Take 12-15 g 12-ketone, add 150 mL 2-glycol ether, 15 mL 80% hydrazine hydrate solution, and 15 g potassium hydroxide. Heat to 30 °C and reflux for 15h, heat to 195-200 °C, refluxed for 2.5h, heat to 217 °C for some moment of reaction cool to 190 °C, add 0.7ml hydrazine hydrate solution, heat from within 215 °C to 220 °C within 3h, cool, add 600mL distilled water, adjust to pH 3 with 10% sulfuric acid, separate out the crystals, filter, wash with water until neutralization. Add ethyl acetate, dump the aqueous layer, use water to wash the organic layer was washed for 1-2 times, vacuum distillation and obtain 3α, 7α-dihydroxy cholanic acid, namely Chenodeoxycholic acid. 3α, 7α-diacetyl methyl cholate → 3α, 7α-diacetoxy-12-Keto ursodeoxycholic acid methyl ester → 3α, 7α-dihydroxy ursodeoxycholic acid (Chenodeoxycholic acid) Preparation of refined ursodeoxycholic acid; Taken 2 g chenodeoxycholic acid, add 100ml of acetic acid and 20g potassium acetate, shake to dissolve. Add potassium chromate 1.5g (dissolved in 10 mL of water), at room temperature overnight, add water 200ml, separate out the crystals, filter, wash, and dry to obtain 3α-hydroxy-7-keto-ursodeoxycholic acid. Take 4g 3α-hydroxy-7-keto-ursodeoxycholic acid, add 100 mL n-butanol, heat to about 115 °C, gradually add 8 g metal sodium after which, white slurry gradually comes out, keep reaction for 30min, add 120ml water, stir and heat to transparently dissolve. Evaporate the organic layer under reduced pressure; add 500 mL water to the residue, dissolve, and filter. Adjust the pH the filtrate to pH 3 with 10% sulfuric acid which will yield white precipitate, filter, wash till neutralization with water, dry, wash with ethyl acetate, crystallize with diluted ethanol and obtain 3α, 7β-dihydroxycholanic acid, that’s refined ursodeoxycholic acid. Chenodeoxycholic acid [potassium chromate] → 3α-hydroxy-7-keto acid [sodium metal, 115 °C] → 3α, 7β-Keto ursodeoxycholic acid methyl ester (Ursodeoxycholic acid) Method 2: Use pig bile or bile salts as raw material; Use thin layer chromatography to isolate ursodeoxycholic acid from pigs bile or bile salt. Pig bile salt contains free and bound type of UDCA whose content is about 30%; pig bile contains bound UDCA whose content is about 0.6%.
