the Pharmacological

Pharmacokinetics Absorption At properties of the person after intravenous administration a pharmacokinetic profile of an ademetionin is biexpotentsialny with a fast phase of distribution in fabrics and clearance with elimination half-life about 1.5 h. Absorption at intramuscular introduction of 96%, the maximum plasma concentration are reached in 45 min. after use. After intake of kishechnorastvorimy tablets of an ademetionin (400 1000 mg) the reached maximum plasma concentration are dose-dependent and make 0.5 1 mg/l in 3 5 hours. The bioavailability after oral administration increases if ademetionin it is applied between meals. Plasma concentration decrease to reference values within 24 hours.


the Volume of distribution makes 0.41 and 0.44 l/kg for doses of an ademetionin of 100 mg and 500 mg respectively. Linking with serum proteins insignificant also makes also le, 5%.


Process of metabolism of an ademetionin is cyclic and is called a cycle of an ademetionin. At the first stage of this cycle the ademetionin-dependent metilaza uses ademetionin as substrate for products S-adenozil-gomotsisteina which is hydrolyzed then to a gomotsistein and adenosine by means of S-adenozil-gomotsistein-gidralazy. Gomotsistein in turn is exposed to the return transformation to methionine by transfer of methyl group from 5 methyltetrahydrofolates. Finally, methionine can be transformed in ademetionin, finishing a cycle.


Approximately at 60% of the total number of the healthy volunteers participating in researches on intake of a radioactive (methyl 14C) ademetionin, renal excretion was 15.5&plusmn, 1.5% in 48 h, excretion with excrements 23.5&plusmn, 3.5% in 78 h.

A pharmacodynamics

Geptral (active agent – S-аденозил-L-methionine (ademetionin)) natural amino acid which is present at all fabrics and fluid mediums of an organism. Geptral (ademetionin) first of all acts as coenzyme and the donor of methyl group in many reactions of transmethylation. Transfer of methyl groups (transmethylation) of an ademetionin is a basis at creation of a phospholipidic cell membrane and plays a role in the fluidity of membranes.

Geptral (ademetionin) is capable to get through a blood-brain barrier. High concentrations of Geptral (ademetionin) influence the transmethylation processes which are very important in brain fabric thanks to influence on metabolism of catecholamines (dopamine, adrenaline, noradrenaline), indolamines (serotonin, melatonin) and a histamine.

Geptral (ademetionin) is also a predecessor of biochemical thiol connections (cysteine, taurine, glutathione, coenzyme A, etc.) in transsulphonating reactions.

Glutathione, the most powerful antioxidant, is an important component for a hepatic detoxication. Geptral increases glutathione level at patients with damage of a liver of both alcoholic, and not alcoholic genesis. Folic acid and B12 vitamin are essential to – nutrients in metabolism and Geptral’s (ademetionina) accumulation.

The intra hepatic cholestasia

Drug is effective at treatment of an intra hepatic cholestasia in liver diseases, during pregnancy and other chronic hepatic diseases.

The intra hepatic cholestasia is a complication of chronic diseases of a liver and is the reason of damage of hepatic cells.

In chronic diseases of a liver such functions of hepatocytes as clearance and regulation of production of bile acids are broken that leads ment of an intra hepatic cholestasia.

Use of an ademetionin was studied at patients with the chronic diseases of a liver which are often followed by a vnutripechechny cholestasia: primary biliary cirrhosis, primary sclerosing cholangitis, lekarstvenno – the induced damages of a liver, a viral hepatitis, the cholestasia induced by parenteral nutrition, damages of a liver of alcoholic and not alcoholic genesis.

A depression

Geptral (ademetionin) was applied parenterally and inside to treatment depressss. Antidepressive action was shown for 5-7 day of treatment in the absence of side effects, including anticholinergic reactions.

An intra hepatic cholestasia of pregnant women

Treatment ademetioniny (in/in, in oil, inside in the form of tablets) is effective at an intra hepatic cholestasia of pregnant women and is shown in the form of reduction of a skin itching and improvement of biochemical parameters.


– an intra hepatic cholestasia at pretsirrotichesky states and cirrhosis

– an intra hepatic cholestasia at pregnant women in the III trimester

– a depressive syndrome

the Route of administration and doses

Treatment can be begun with parenteral administration of drug (intravenously slowly or intramusculary) with the subsequent use of drug in the form of tablets or at once with use of tablets.

It is necessary to swallow of tablets without chewing. The tablets Geptrala are covered with a special cover which is dissolved only in intestines thanks to what ademetionin it is released in a duodenum. For the best absorption of active agent and full therapeutic effect the pill should be taken between meals. The tablet Geptrala should be taken out from the blister just before reception. In case of discoloration of tablets from initial from white to yellowish (owing to damage of an aluminum cover of the blister) it is necessary to refrain from their use.

Initial therapy (oral administration) the Recommended dose makes 10 25 mg/kg/day. The usual initial dose makes on 500 mg 1-2 times a day. The daily dose should not exceed 1500 mg.

Maintenance therapy: 2 3 tablets a day in (1000 1500 mg/day.)

Duration of therapy depends on weight and a course of the disease and is defined by the doctor individually.

Patients of advanced age.

Treatment is recommended to be begun with the smallest recommended dose, in view of decrease in hepatic, renal or warm function, existence of the accompanying morbid conditions and use of other medicines.

Use for patients with a renal failure

of Researches at patients with a renal failure was not carried out, in this regard it is recommended to be careful at use of an ademetionin for such patients.

Use for patients with a liver failure

the Parameters of pharmacokinetics of an ademetionin are similar at healthy volunteers and at patients to chronic diseases of a liver.

Medicinal interactions

the message about development of a serotoninovy syndrome in the patient applying ademetionin and klomipramin Was beta. It is necessary to apply with care Geptral along with selective serotonin reuptake inhibitors, tricyclic antidepressants (such as klomipramin), the drugs and vegetable means containing tryptophane.

Special instructions

At patients with pre-cirrhotic states and cirrhosis with a giperkreatininemiya it is necessary to control creatinine level during reception of the tablets Geptrala.

Insufficiency of B12 vitamin and folic acid can lead to reduction of concentration of an ademetionin therefore to patients of risk group (anemia, a liver failure, pregnancy or potential for a lack of vitamins because of other diseases or preferences in food, such as strict vegetarians) neokhodimo to carry out daily blood tests to check plasma levels. If insufficiency is found, treatment by B12 vitamin and folic acid is recommended along with use of an ademetionin.

Some patients at therapy ademetioniny can have a dizziness. It is not necessary to run vehicles or to work with other mechanisms before total disappearance of symptoms which can affect speed of response at the specified types of activity.

Geptral is not recommended for use for patients with bipolar psychoses. Messages about transition of a depression to a hypomania or mania at treatment were received ademetioniny.

Patsiyentov it is necessary to warn about need of informing the doctor if during therapy by Geptral the symptoms of their disease (depression) do not pass or worsen. Patients with a depression need careful observation and continuous mental health services at treatment ademetioniny for the purpose of control of efficiency of treatment.

One literary message about a serotoninovy syndrome at the patient receiving ademetionin and klomipramin was received. As the possibility of medicinal interaction is not excluded, it is necessary to apply with care Geptral along with selective serotonin reuptake inhibitors, tricyclic antidepressants (such as klomipramin), the drugs and vegetable means containing tryptophane.

Messages about the tranzitorny or amplifying alarm at the patients receiving treatment Geptraly (ademetioniny) were received. In most cases, the treatment termination was not required. In certain cases the alarm stopped after a dose decline or the termination of therapy.
