Pharmacological action of

Pharmacotherapeutic group

Means of lowering the secretion of the glands of the stomach - proton pump inhibitor

ATX code: [A02BC04]

Pharmacological properties of

Pharmacodynamics

Rabeprazole benzodizam class. It inhibits the secretion of gastric juice by specific inhibition of H + / K + -ATPase on the secretory surface of parietal cells of the stomach. It blocks the final stage of hydrochloric acid secretion, reducing the content of basal and stimulated secretion, regardless of the nature of the stimulus. Possessing high lipophilicity, it easily penetrates into the parietal cells of the stomach, concentrates in them, providing a cytoprotective effect and increasing the secretion of bicarbonate. The antisecretory effect after oral administration of 20 mg of rabeprazole occurs within 1 hour and reaches a maximum after 2-4 hours inhibition of basal and food-stimulated acid secretion 23 hours after the first dose is 62 and 82%, respectively, and lasts up to 48 hours. When you stop taking secretory activity is restored within 1-2 days. During the first 2-8 weeks of rabeprazole therapy, the concentration of gastrin in the blood plasma increases (which is a reflection of the inhibitory effect on the secretion of hydrochloric acid) and returns to its original levels 1-2 weeks after its cancellation. Rabeprazole does not have anticholinergic properties, does not affect the central nervous system (CNS), the cardiovascular and respiratory systems. Against the background of taking rabeprazole, no stable changes were found in the morphological structure of enterochromaphine-like cells, in the degree of gastritis, in the frequency of atrophic gastritis, intestinal metaplasia, or the spread of Helicobacter pylori infection. 3

Pharmacokinetics

Absorption of

Rabeprazole is rapidly absorbed from the intestine, and its maximum plasma concentration is reached approximately 3.5 hours after a dose of 20 mg. The change in the maximum plasma concentrations (Cmax) and the area under the concentration-time curve (AUC) of rabeprazole are linear in the dose range from 10 to 40 mg. The absolute bioavailability after oral administration of 20 mg (compared with intravenous administration) is about 52%. In addition, bioavailability does not change with multiple doses of rabeprazole. In healthy volunteers, the plasma half-life is about 1 hour (varying from 0.7 to 1.5 hours), and the total clearance is 3.8 ml / min / kg. In patients with chronic liver damage, the AUC is doubled compared with healthy volunteers, which indicates a decrease in the metabolism of the first passage, and the half-life from plasma is increased by 2 to 3 times. Neither the time of taking the drug during the day, nor antacids affect the absorption of rabeprazole. Taking the drug with fatty foods slows down the absorption of rabeprazole for 4 hours or more, however, neither Cmax nor the degree of absorption change.

Distribution of

In humans, the degree of binding of rabeprazole to plasma proteins is about 97%.

Metabolism and excretion of

In healthy people

After administration of a single oral dose of 20 mg of 14C-labeled rabeprazole, no unchanged drug was found in the urine. About 90% of rabeprazole is excreted in the urine mainly in the form of two metabolites: a conjugate of mercapturic acid (M5) and carboxylic acid (M6), as well as in the form of two unknown metabolites identified during toxicological analysis. The rest of the taken rabeprazole is excreted in the feces. The total elimination is 99.8%. These data indicate a small excretion of rabeprazole metabolites with bile. The main metabolite is thioether (M1). The only active metabolite is desmethyl (M3), however, it was observed in low concentration in only one study participant after taking 80 mg of rabeprazole.

End-stage renal failure

In patients with stable end-stage renal failure who require maintenance hemodialysis (creatinine clearance <5 ml / min / 1.73 m2), rabeprazole excretion is similar to that for healthy volunteers. AUC and Cmax in these patients were approximately 35% lower than in healthy volunteers. On average, the half-life of 4 rabeprazole was 0.82 hours in healthy volunteers, 0.95 hours in patients during hemodialysis, and 3.6 hours after hemodialysis. The clearance of the drug in patients with kidney diseases requiring hemodialysis was approximately two times higher than in healthy volunteers.

Chronic compensated cirrhosis

Patients with chronic compensated cirrhosis of the liver tolerate rabeprazole in a dose of 20 mg once a day, although AUC is doubled and Cmax is increased by 50% compared with healthy volunteers of the corresponding gender.

Elderly patients

In older patients, elimination of rabeprazole is somewhat delayed. After 7 days of taking rabeprazole at 20 mg per day in elderly patients, the AUC was approximately twice as large, and Cmax increased by 60% compared to young healthy volunteers. However, no evidence of cumulation of rabeprazole was noted.

CYP2C19 polymorphism

In patients with a slow metabolism of CYP2C19 after 7 days of taking rabeprazole at a dose of 20 mg per day, AUC increases by 1.9 times, and the half-life by 1.6 times compared with the same parameters for “fast metabolizers”, while Cmax increases by 40%.

Dosage and Administration

Capsules of the drug Rabeprazole-SZ should be swallowed whole. It was found that neither the time of day, nor food intake affect the activity of rabeprazole.

In case of gastric ulcer in the acute stage and anastomosis ulcer, it is recommended to take 10 mg or 20 mg orally once a day. Usually, cure occurs after 6 weeks of therapy, but in some cases, the duration of treatment can be increased by another 6 weeks.

In case of peptic ulcer of the duodenum, it is recommended to take orally 20 mg once a day. In some cases, the therapeutic effect occurs when taking 10 mg once a day. The duration of treatment is from 2 to 4 weeks. If necessary, the duration of treatment can be increased by another 4 weeks. When treating erosive gastroesophageal reflux disease (GERD) or reflux esophagitis, it is recommended that you take 10 mg or 20 mg orally once a day. The duration of treatment is from 4 to 8 weeks. If necessary, the duration of treatment can be increased by another 8 weeks.

With maintenance therapy for gastroesophageal reflux disease (GERD), it is recommended that you take 10 mg or 20 mg orally once a day. The duration of treatment depends on the patient's condition.

In non-erosive gastroesophageal reflux disease (NERD) without esophagitis, it is recommended that you take 10 mg or 20 mg orally once a day. If after four weeks of treatment the symptoms do not disappear, an additional examination of the patient should be carried out. After stopping the symptoms, to prevent their subsequent occurrence, the drug should be taken orally at a dose of 10 mg once a day, on demand.

For the treatment of Zollinger-Ellison syndrome and other conditions characterized by pathological hypersecretion, the dose is selected individually. The initial dose is 60 mg per day, then the dose is increased and the drug is prescribed in a dose of up to 100 mg per day with a single dose or 60 mg twice a day. For some patients, fractional dosing of the drug is preferred. Treatment should continue as needed. In some patients with Zollinger-Ellison syndrome, the duration of treatment with rabeprazole was up to one year.

For eradication of Helicobacter pylori it is recommended to take 20 mg orally 2 times a day according to a certain scheme with the appropriate combination of antibiotics. The duration of treatment is 7 days.

Patients with Renal and Hepatic Insufficiency

Dose adjustment is not required for patients with renal failure. In patients with mild to moderate hepatic insufficiency, the concentration of rabeprazole in the blood is usually higher, than healthy volunteers. When prescribing the drug Rabeprazole-SZ, patients with severe severity of liver failure should be careful.

Elderly patients

Dose adjustment not required.

Children

The safety and efficacy of rabeprazole 20 mg for short-term (up to 8 weeks) treatment of GERD in children 12 years of age and over is confirmed by extrapolating the results of adequate and well-controlled studies that support the effectiveness of rabeprazole for adults and safety and pharmacokinetics studies for pediatric patients. The recommended dose for children aged 12 years or more is 20 mg once a day for up to 8 weeks. The safety and effectiveness of rabeprazole for the treatment of GERD in children under the age of 12 years has not been established. The safety and effectiveness of rabeprazole for other indications have not been established for pediatric patients.

Drug Interaction

Slows the elimination of some drugs metabolized in the liver by microsomal oxidation (diazepam, phenytoin, indirect anticoagulants). Co-administration of rabeprazole with ketoconazole or itraconazole can significantly reduce the concentration of antifungal drugs in blood plasma. The use of proton pump inhibitors (PPIs) with atanazavir is not recommended, as the effects of atanazavir are greatly reduced. Rabeprazole inhibits cyclosporine metabolism. At simultaneous intake of PPI and methotrexate it is possible to assume increase of concentration of the last and / or its metabolite of hydroxymethotrexate and increase of half-life. When co-administered with rabeprazole, amoxicillin and clarithromycin, the AUC and Cmax values ​​for clarithromycin and amoxicillin were similar when compared with combination therapy with monotherapy. The AUC and Cmax of rabeprazole increased by 11% and 34%, respectively, and the AUC and Cmax of 14-hydroxyclarithromycin (the active metabolite of clarithromycin) increased by 42% and 46%, respectively. This increase in indices was not considered clinically significant. Concomitant administration of rabeprazole and suspensions of antacids containing aluminum and / or magnesium hydroxide does not lead to a clinically relevant interaction.



overdose Symptoms of
