Definitions
- the present invention relates to a cholestatic improving agent containing tauroursodeoxycholic acid as an active ingredient.
- Tauroursodeocholic acid is a compound represented by the following structural formula, which is a taurine conjugate of ursodeoxycholic acid.
- Bile depression is a condition in which bile secretion, an important function of the liver, is impaired, and the flow of bile from the liver to the duodenum via the biliary tract is reduced, resulting in stasis of bile components.
- extrahepatic obstructive jaundice which has a clear mechanism of mechanical obstruction such as tumors and gallstones
- intrahepatic cholestasis which shows cholestasis despite the fact that the obstruction is not evident macroscopically.
- intrahepatic cholestasis is acute, associated with drug-induced hepatitis, viral hepatitis, It is classified into chronic type typified by primary biliary cirrhosis (PBC), recurrent type that occurs during pregnancy, etc., all of which are characterized by severe jaundice and persistent pruritus .
- PBC primary biliary cirrhosis
- tauroursodeoxycholic acid compared to ursodeoxycholic acid, It has been found that it has good solubility, is easy to prepare as an injection, and has a cholestatic improvement effect.
- a cholestatic agent comprising tauroursodeoxycholic acid as an active ingredient.
- the tauroursodeoxycholic acid used in the present invention may be a pharmacologically acceptable salt, and is a well-known method for producing a taurine conjugate of bile acid using ursodequincholic acid as a raw material. It can be manufactured by applying. For example, it can be produced by reacting ursodeoxycholic acid in a non-hydrating solvent with alkyl chlorocarbonate under a basic catalyst, and reacting this solution with taurine in an aqueous alkali solution.
- estradiol 1 ⁇ ⁇ 17 3—D-glucuronide (E—17—G) 10 ⁇ mo 1 e / kg was administered once from the femoral vein.
- tauroursodeoxycholic acid 0.6 mo 1 emi 100 gW.B. was continuously administered from the femoral vein for 2 hours, and the bile flow was measured over time.
- Taurol sodoxycholic acid inhibits the reduction of bile flow due to E—17—G at doses of 0.3 zmo 1 e / min / 100 g B.W. It was more significant than deoxycholic acid.
- ⁇ -naphthylisotoosinate ( ⁇ ⁇ ⁇ ) 8 O mg / kg was administered to male ICR mice, and tauroursodeoxycolic acid was administered 100 hours before and 2 hours after administration of ANIT.
- ⁇ : 1200 zmol / kg was administered via the tail vein.
- Serum pyrylvin concentration, total bile acid concentration and LDH activity were measured after ANIT administration2.
- Tauroursodeoxycholate inhibited ANIT-induced increases in bilirubin concentration, total bile acid concentration, and LDH activity.
- Example 1 Man, 71 years old, 46 kg In this case, the GOT and GPT levels increased from the third day after administration due to the drug administered for the treatment of neuralgia in January and February 1992. UZ 1, GPT 664 U / 1, and the total pyrirubin level increased to 18.6 mg / d 1 even after discontinuation of drug administration. Abdominal ultrasonography revealed thickening of the gall g wall, and severe jaundice was observed. The patient was diagnosed with cholestatic depression due to drug-induced liver injury.
- total pyrilrubin value ⁇ 6.9 mg gZd 1
- no improvement was observed in subjective symptoms such as skin pruritus and epigastric discomfort.
- Cholic acid was injected intravenously once daily at a dose of 100 mg for 14 days.
- the total pyrilrubin level was 2.1 mg / d 1
- GOT was reduced to 45 UZ 1
- GPT was reduced to 36 UZ 1
- the jaundice symptoms disappeared, subjective symptoms such as skin pruritus and epigastric discomfort Also disappeared.
- the patient was a Japanese living in San Francisco, but in March 1993 he felt pruritus on his fingers, was diagnosed with viral acute hepatitis at a local hospital, and received temporary treatment.
- tauroursodeoxycholate was administered intravenously at a dose of 100 mg per dose for 14 days.
- the total pyrilvin level before the start of administration decreased from 31.4 mg / dl to 13.7 mg / d1 and the total bile acid amount from 21 zmol Zl to 12 mole Zl. From 3 onwards, subjective symptoms such as skin itching and anorexia disappeared, and jaundice symptoms were reduced.
- liver biopsy showed necrosis of parenchymal cells around the center of the lobule, and was diagnosed with drug-induced liver injury.
- Xycolic acid was intravenously infused at a dose of 300 mg once per day for 14 days.
- the total pyrilrubin value was 2.8 mg Zd1
- GOT was 171 U / 1
- GPT was 1
- the measured value was not increased even 2 weeks after the completion of the administration, and improvement of jaundice symptoms due to cholestasis was observed.
- total pyrilrubin value 16.19 mg Zd 1
- tauroursodeoxycholic acid was infused intravenously once daily at a dose of 30 Omg for 14 days.
- total bilirubin decreased to 4.4 mg / d 1
- GOT decreased to 48 UZ1
- GPT decreased to 36 U / 1
- jaundice symptoms began to decrease after one week, and after 10
- subjective symptoms such as general malaise disappeared.
- Example 6 Male, 55 years old, 60 kg D In this case, when he noticed jaundice in the middle of May 1993, he was diagnosed with endoscopic retrograde cholangiohepatic angiography (ERCP). The patient was diagnosed with obstructive jaundice because of an irregular stenosis of 3-4 cm, and a nasal bile duct drainage (ENBD) was performed on May 31.
- ERCP endoscopic retrograde cholangiohepatic angiography
- ENBD nasal bile duct drainage
- taurol sodoxycholic acid was intravenously injected at a dose of 100 mg per dose for 22 days.
- an increase in bile flow and a decrease in the total pyrilrubin level were clearly observed, and with this, jaundice and pruritus dermatitis were improved.
- PTCD percutaneous transhepatic biliary drainage
- Acute toxicity (LD 50 ) of tauroursodeoxycholic acid by intravenous administration was measured using 6-week-old CD male and female rats and 8- to 11-month-old male and female beagle dogs.
- LD 5 The values for rats were 600-80 Omg / kg for males and 800-100 mg / k for females. In beagle dogs, the dose was 300-600 mgZkg for both males and females.
- tauroursodeoxycholic acid is an active ingredient Can be referred to as a cholestatic improving agent having a hepatocyte protective action.
- the dosage of tauroursodeoxycholic acid for patients varies depending on age, symptoms, etc., but for adults, 50 to 300 mg orally, preferably 200 to 150 mg per patient
- the dose should be 30 to 120 mg, preferably 100 to 60 Omg, intravenously, and used in 1 or 2 divided doses.
- the bile stasis ameliorating agent of the present invention includes various pharmaceutical compositions containing a solid or liquid pharmaceutical carrier harmless to the active ingredient tauroursodeoxycholic acid as long as the above-mentioned daily dose can be maintained. Things are also included.
- the pharmaceutical composition can be in the form of tablets, capsules, powders, fine granules, granules, solutions, syrups, or injections.
- tauroursodeoxycholic acid which is an active ingredient of the present invention, has high water solubility, it can be made into an aqueous injection with purified water or physiological saline. In this case, it is preferable that tauroursodeoxycholic acid is contained at a concentration of 1% to 10% (W / V).
- a solution of 10 g of tauroursodeoxycholic acid and 46 g of D-mannitol prepared in purified water with a total volume of 100 ml was treated in the same manner as in Formulation Example 1 to obtain tauroursodeoxycholic acid.
- An injection containing 1% (w / v) cholic acid was produced.
- tauroursodeoxycholic acid of the present invention is excellent in water solubility, exhibits a bile effect and has a hepatocyte protective effect, it has an intrahepatic bile depressant improving agent and bile after obstructive jaundice, and in the treatment of obstructive jaundice. It is useful as a stasis improving agent.
