Pharmacological properties:

Pharmacodynamics. Renders membrane stabilizing, hepatoprotective, cholagogue, holelitichesky and immunomodulatory action. It is built in a hepatocyte membrane, stabilizes its structure and protects a hepatic cell from the striking factors. Competitively inhibits absorption of lipophilic bile acids in intestines, raises their "fractional" turn at enterogepatichesky circulation. Induces bilification, rich with bicarbonates that leads to increase in its passage and stimulates removal of toxic bile acids with a stake. Replacing unpolar bile acids, creates the non-toxic mixed micelles. Slows down synthesis of cholesterol in a liver. Forms rare crystals with cholesterol molecules and interferes with its absorption in intestines, reduces a bile litogennost, reduces a holato-cholesteric index, renders assistance to dissolution of cholesteric stones and prevents their education. At a cholestasia activates Sa2+-zavisimuyu α-proteinase and stimulates an exocytosis, reduces concentration of bile acids (cholic, lithocholic, deoxycholic, etc.).

Immunological activity is caused by reduction of an expression of histocompatibility antigens of HLA-1 on hepatocytes and HLA-2 on holangiotsita, reduces "attack" of immunocompetent immunoglobulins (first of all, Ig M), reduces formation of cytotoxic T lymphocytes.

Pharmacokinetics. After intake of Ursokhol® it is well soaked up in a small bowel due to passive diffusion, and in an ileal gut – by means of active transport. The maximum concentration in plasma is reached within 30 - 60 min. after reception.

At regular use becomes the main bile acid in a blood plasma, making about 96 - 99% of their general contents.

 The maximum concentration in bile is noted at a daily dose 10 - 14 mg/kg. At further increase in a dose concentration of ursodezoksikholevy acid in bile does not increase. Gets through a placental barrier. About 50 - 70% of a dose are removed with bile and partially – with excrements.

Pharmaceutical characteristics.

Main physical and chemical properties: the white, opaque, solid gelatin capsules containing white powder or granules.

Side effects:

Side effects from digestive tract: liquid excrements or diarrhea during therapy by ursodezoksikholevy acid (often).

At therapy of the developed stages of primary biliary cirrhosis the decompensation of hepatic cirrhosis which partially regressed after the treatment termination was observed.

Reactions of hypersensitivity it is (very rare): rash can be observed.


Interaction with other medicines:

The УрсохолÒ capsules cannot be used along with Colestyraminum, kolestipoly or the antiacid drugs containing aluminum hydroxide and (or) smectite (aluminum oxide) as these drugs connect ursodezoksikholevy acid in intestines and thus reduce its absorption and efficiency. If use of the drugs containing one of these substances nevertheless is necessary, they need to be applied at least for 2 h to or after reception of the УрсохолÒ capsules.

In some cases the УрсохолÒ capsules can reduce ciprofloxacin absorption.

Урсохол® can strengthen absorption of cyclosporine from intestines. Therefore, at the patients applying cyclosporine it is necessary to check concentration of cyclosporine in blood and in case of need to modify a cyclosporine dose.

Increases effect of peroral antidiabetic means.

Ursodezoksikholevy acid reduces the maximum concentration in plasma and the area under a curve of the calcic antagonist of a nitrendipin. Proceeding from it, and also from one message on interaction with substance dapsone (reduction of therapeutic effect) and from the researches in vitro, it is possible to assume that ursodezoksikholevy acid induces activity of the P450 3A4 cytochrome metabolizing drug.

Therefore at simultaneous use of the means which are metabolized with the participation of this enzyme it is necessary to be careful and consider possibility of need for dose adjustment.

Hypersensitivity to drug components.

Patients with a gall bladder which is not visualized by radiological methods, calcific stones of a gall bladder, the broken contractility of a gall bladder, patients with frequent bilious gripes.
