Indications to use: Peptic ulcer of a stomach. Reflux esophagitis. Zollingera-Ellison's syndrome. Stressful ulcers. Eradikation N. pylori.


General characteristics. Structure:

Active ingredient: 10 mg or 20 mg of a rabeprazol of sodium.

Excipients: magnesium oxide, Mannitolum, starch corn, K30 povidone, the hypro rod low-replaced the sodium stearylfumarating.

Structure of a cover: целлацефат, titanium dioxide, dye ferrous oxide red.

Antiulcerous drug.




Pharmacological properties:

Pharmacodynamics. Antiulcerous drug from group of inhibitors of the protonew pump (N + / To +-ATF-azy), is metabolized in covering cells of a stomach to active sulphonamide derivatives which inactivate the H+/K sulphhydryl groups +-ATF-azy.

Blocks a final stage of secretion of Acidum hydrochloricum, reducing the content of basal and stimulated secretion, irrespective of the irritant nature.

Has high lipophilicity, easily gets into covering cells of a stomach and concentrates in them, having cytoprotective effect.

The anti-secretory effect after oral administration of 20 mg occurs during 1 h and reaches a maximum in 2-4 h; oppression by basal and stimulated food of secretion of acid in 23 h after the first reception makes 62% and 82% respectively; action duration - 48 h. After the end of reception secretory activity is normalized within 2-3 days.

Concentration of gastrin in blood serum increases and returned to the first 2-8 weeks of therapy to initial levels within 1-2 weeks after drug withdrawal. Does not influence TsNS, cardiovascular and respiratory systems.

Pharmacokinetics. Absorption and distribution. It is absorbed from a small intestine (because of existence of an acid resisting kishechnorastvorimy cover). Absorption is high, time of achievement of Cmax - 3.5 h. Cmax and AUC values have linear character in the range of doses from 10 to 40 mg. Bioavailability - 52%, does not increase at multiple dose.

Communication with proteins of plasma - 97%.

Metabolism and removal. It is metabolized in a liver with participation of isoenzymes of P450 cytochrome (CYP 2C19 and CYP 3A4). T1/2 - 0.7-1.5 h, clearance - 283 ± 98 ml/min. It is removed by kidneys - 90% in the form of two metabolites: conjugate of mercapturic acid (M5) and carboxylic acid (M6); intestines - 10%.

Pharmacokinetics in special clinical cases. At patients with a chronic liver failure of weak or average degree after a single dose of AUC T1/2 - by 2-3 times increases twice. After reception of 20 mg of a rabeprazol within 7 days of AUC T1/2 - by 1.2 times increases by 1.5 time. At the patients with a stable end-stage of a renal failure needing a hemodialysis (KK less than 5 ml/min. / 1.73 sq.m), distribution of a rabeprazol of sodium is close to that at healthy faces.

At elderly patients after reception of a rabeprazol within 7 days of AUC is twice more, Cmax - is 60% more, than at young people.

At patients with the slowed-down metabolism of CYP2C19 after 7 days of reception of a rabeprazol in a dose of 20 mg in days of AUC T1/2 by 1.6 times in comparison with the same parameters at "bystry metabolizator" while Cmax increases by 40% increases by 1.9 times, and.


Indications to use:

a peptic ulcer of a stomach and duodenum in an aggravation stage;

— gastroesophageal reflux disease;

— hyper secretory states, including Zollingera-Ellison's syndrome;

stressful ulcers of a GIT.

As a part of complex therapy:

— Helicobacter pylori eradikation at patients with a peptic ulcer of a stomach and duodenum or chronic gastritis;

— treatment and prevention of a recurrence of the peptic ulcer connected with Helicobacter pylori.


Route of administration and doses:

Drug is appointed on 20 mg of 1 times/days. A pill should be taken inside, in the morning before meal, swallowing entirely, not chewing and without crushing.

At a peptic ulcer of a duodenum and a peptic ulcer of a stomach in a stage of an aggravation appoint 20 mg (1 таб.) 1 times/days in the morning within 4-6 weeks.

At a gastroesophageal reflux disease (GERB) appoint 20 mg (1 таб.) 1 times/days within 4-8 weeks.

For a maintenance therapy at GERB - in a dose of 10 or 20 mg of 1 times/days depending on the answer of the patient.

For a symptomatic treatment of GERB at patients without esophagitis - in a dose of 10 mg of 1 times/days within 4 weeks.

For the treatment of a syndrome of Zollingera-Ellison and other states which are characterized by pathological hypersecretion, the dose is selected individually.

For the treatment of a peptic ulcer of a duodenum or chronic gastritis connected with infection of Helicobacter pylori the course of treatment lasting 7 days of one of the following combinations of drugs is recommended:

Hayrabezol on 20 mg of 2 times/days + кларитромицин on 500 mg of 2 times/days and amoxicillin on 1 g 2 times/days.

Hayrabezol on 20 mg of 2 times/days + кларитромицин on 500 mg of 2 times/days and metronidazole on 400 mg of 2 times/days.


Features of use:

Use at pregnancy and feeding by a breast. Rabeprazol it is not necessary to appoint at pregnancy (there are no data on safety of use of a rabeprazol at pregnancy).

It is unknown whether it is allocated рабепразол with breast milk. The corresponding researches at the feeding women were not conducted. For the period of treatment it is necessary to stop breastfeeding.
