Definitions

  • the present invention relates to a pharmaceutical preparation for chronic hepatitis treatment.
  • Chronic hepatitis is an inflammatory disease of the liver which persists for at least 6 months and is considered to be caused by an infection by the hepatitis virus, autoimmunity, certain kinds of drugs, and the like.
  • a liver disease will take the course of an occurrence of a transitional extension, chronic change, and inverterate hepatitis, and in some cases, that the disease takes 10 or more years before healing or the disease may be migrated to cirrhosis, and a further complication of primary hepatoma may cause death in many cases.
  • the migration percentage from chronic hepatitis to cirrhosis is not constant, depending on the source, but is approximately 40%.
  • the healing percentage is much smaller, and has been estimated to be around 10%. Accordingly, about half of the cases have persistent subjective symptoms and liver function abnormalities and are difficult to cure.
  • Chronic hepatitis is classified into an active type and a nonactive type, by liver function and liver biopsis image, and the active type and nonactive type are mutually migratable to each other.
  • the therapy therefore is performed at the time when an active lesion exists and the practiced drug therapy is based on instructions on food intake and how to relax.
  • Neo Minofagen C ⁇ as liver protecting agents, interferon (IFN), arabinoside-A (Ara-A) as antiviral agents, and glucocorticoid (GC) withdrawal as the immune control therapy have been practiced, but some problems arise in the use of these prior art methods.
  • IFN interferon
  • Ara-A arabinoside-A
  • GC glucocorticoid
  • the objects of the present invention are to eliminate the above-mentioned disadvantages of the prior art and to provide a pharmaceutical preparation for chronic hepatitis treatment capable of being orally administered and having few side effects and a high efficacy.
  • a pharmaceutical preparation for chronic hepatitis treatment comprising an active vitamin D, as an active ingredient, and a carrier therefore.
  • Figure 1 shows the change of GOT when l ⁇ -hydroxy- vitamin D 3 is administered.
  • Fig. 2 shows the change of GPT when l ⁇ -hydroxy- vitamin D is administered.
  • Active vitamin D's such as la-hydroxyvitamin D, l 24(R)-dihydroxyvitamin D, l ⁇ , 25-dihydroxyvitamin D, promote an absorption of calcium in the small intestine promote bone resorption and bone formation in bones, an are well known in the art as a therapeutic agent for diseases due to various calcium metabolism abnor ⁇ malities.
  • the present inventors made an intensive investiga- tion of the effects of the active vitamin D on chronic hepatitis, and consequently, surprisingly found that th active vitamin D has the action of lowering the GOT and GPT, which are indices of liver function.
  • the active vitamin D usable in the present invention includes the active vitamin D « , the active vitamin D, , and derivatives thereof.
  • Typical examples of such compounds are l ⁇ -hydroxyvitamin D, l ⁇ , 24(R)- dihydroxyvita in D, l ⁇ , 25-dihydroxyvitamin D, l ⁇ , 24 25-trihydroxyvitamin D, 24, 24-difluoro-l f 25-dihy- droxyvita in D, 26, 26, 26, 27, 27, 27-hexafluoro-l ⁇ , 25-dihydroxyvitamin D, 25-hydroxyvitamin D.,-26, 23-lactone and l ⁇ , 25-dihydroxyvitamin D-,-26, 23-lactone.
  • l ⁇ -hydroxy ⁇ vitamin D, , l ⁇ » 24(R)-dihydroxyvitamin D, , l ⁇ j 25-dihydroxyvitamin D are preferable, and particularly l ⁇ , hydroxyvitamin D, is most preferred.
  • active ingredients can be used as oral preparation in the form of, for example, soft capsules, hard capsules, tablets, powders, granules, or syrup, or optionally can be used as parenteral preparations in th form of injections, or external preparations, with the use of appropriate vehicles including excipients according to conventional methods.
  • Examples of the vehicles usable in the present invention are vegetable oil or mineral oils, white petrolatum, branched chain fats or oils, animal fats an high molecular weight alcohols for liquid agents or external application agents.
  • vegetable oils corn oil, cotton oil, coconut oil, almond oil
  • middle chain length fatty acid triglycerides are preferred.
  • examples of the vehicles for solid agents usable are cellulose derivatives (crystalline cellulose, hydroxypropyl cellulose, hydroxypropyl-methyl cellulose, methyl cellulose), polyvinylpyrolidone, dextrin, cyclodextrin, casein, lactose, mannitol, gelatin or starch. Among them, lactose, polyvinylpyrolidone etc. are preferred.
  • the content of the active ingredient i.e., the active vitamin D in the composition
  • the content of the active ingredient is preferably (0.00004 - 0.2) x 10 -4% by
  • the dose of the active ingredient is preferably about 0.01 to 10 ⁇ g/day/person, more preferably 0.25 to
  • preparations are obtained which satisfy such conditions.
  • Example 1 Active vitamin D- , l ⁇ -Hydroxyvitamin D_, ,
  • Fig. 1 and Fig. 2 The mean GOT and GPT levels for 6 months before and after the administration are shown in Fig. 1 and Fig. 2, respectively. It is clear from Fig. 1, that the mean GOT level was reduced from 173.9 KU to 83.1 KU by the treatment. It was also confirmed that the mean GPT level was reduced from 172.4 KU to 83.2 KU. These reductions of GOT and GPT levels to 100 or less after administration, it is expected that the migration from chronic hepatitis to cirrhosis can be inhibited. Also, hypercalcemia and side effects were not observed during the test period.
  • BLP 300 ⁇ q protein/ml
  • CFA Complete Freund's Adjuvant
  • mice To DBA/2 strain male mice (7 weeks old) were intraperitoneally injected with 0.25 ml of rabbit ⁇ globulin (RGG» 4 mg/ml) emulsified with an equal volume of CFA. Five days later, 0.6 ml of the anti-BLP antibody was injected through the tail vein, and blood for GPT assay was collected from the right ventricle 18 hours after antibody injection. l ⁇ -OH-D, (0.8, 4, or 20 ng/kg/day) was orally administered once a daily for 7 days from one day before the RGG injection. The results are shown in Table 1.
  • the mean GPT level was 72.5 KU/1, which was clearly higher than that of normal mice and RGG-treated mice: mean levels 14.0 and 11.8 KU/1, respectively.
  • l ⁇ -0H-D 3 at doses of 0.8, 4 and 20 ng/kg/day, inhibited the mean GPT level by 40.3, 45.7, and 44.8%, respectively.
  • Example 3 acnes LPS-induced Hepatitis Model .
  • Balb/c mice (male, 8 weeks old) were injected with 0.1 mg of heat-killed Propionibacterium acnes (P. acnes) through the tail vein.
  • P. acnes heat-killed Propionibacterium acnes
  • 3 ⁇ q of lipopolysaccharide (LPS) derived from E. coli was injected through the same route. Blood was collected 18 hours thereafter, from the right ventricle, and the serum GPT level was measured.
  • l ⁇ -OH-D (4, 100 ng/kg/day) was orally administered for 9 days from one day before the P. acnes treatment. The results are shown in Table 2.
  • Active vitamin D, , l ⁇ -hydroxyvitamin D, was orally administered, at a dose of 1.5 ⁇ q/day for 14 months into to a patient (female, age 50) with chronic hepatitis confirmed by liver biopsy and serologic study.
  • the liver function (GOT, GPT) and the liver biopsy were evaluated.
  • the GOT and GPT levels were reduced from 130 KU and 132 KU, and from 132 KU to 30 KU, respectively. It was confirmed by a tissue observation of the liver bio ass examination that the remarkable decrease in the inflammation observed before and after the administration. The histopathological finding was not substantially different from normal tissue. No side effects such as hypercalcemia were observed during the examination.
