Long-term maintenance of healing of erosive or ulcerative gastroesophageal reflux
disease (GERD). Treatment of symptoms (i.e. heartburn and regurgitation) in symptomatic gastroesophageal reflux disease (GERD), also called nonerosive reflux disease (NERD). Symptomatic relief and healing of duodenal ulcers. Symptomatic relief and healing of gastric ulcers. Long-term treatment of pathological hypersecretory conditions, including Zollinger- Ellison syndrome.
GeriatricsWARNINGS AND PRECAUTIONS, SPECIAL POPULATIONS
: See
Pediatrics (<18 years of age):
The safety and efficacy of rabeprazole have not been established in children under the age of 18 years.
Patients who are hypersensitive to rabeprazole, substituted benzimidazoles or to any ingredient in the formulation or component of the container. For a complete listing, see the DOSAGE FORMS, COMPOSITION AND PACKAGING section of the Product Monograph.
When gastric ulcer is suspected, the possibility of malignancy should be excluded before therapy with Sandoz Rabeprazole is instituted, as treatment with rabeprazole may alleviate symptoms and delay diagnosis.
Symptomatic response to therapy with Sandoz Rabeprazole (rabeprazole sodium) does not preclude the presence of gastric malignancy. Steady state interactions of rabeprazole and warfarin have not been adequately evaluated in patients. There have been reports of increased INR and prothrombin time in patients receiving proton pump inhibitors, including rabeprazole, and warfarin concomitantly. Increases in INR and prothrombin time may lead to abnormal bleeding and even death. Patients treated with a proton pump inhibitor and warfarin concomitantly may need to be monitored for increases in the INR and prothrombin time. As demonstrated with other PPI's, prolonged use may impair the absorption of protein-bound Vitamin B12 and may contribute to the development of Vitamin B12 deficiency.
Sandoz Rabeprazole tablets can be taken with or without meals. Patients should be advised that Sandoz Rabeprazole tablets should be swallowed whole, not chewed or crushed.
For patients with severe liver disease, dosage adjustment should be considered.
No dosage adjustment is necessary in patients with renal insufficiency.
The safety of Sandoz Rabeprazole treatment in pregnancy has not been established. Sandoz Rabeprazole tablets should not be administered to pregnant women unless the expected benefits outweigh the potential risks to the fetus.
It is not known whether rabeprazole is excreted in human milk. Sandoz Rabeprazole tablets should not be given to nursing mothers unless the expected benefits outweigh the potential risks to the infant.
The safety and efficacy of rabeprazole have not been established in children under the age of 18 years.
Ulcer healing rates in elderly patients are similar to those in younger patients. Adverse events and laboratory test abnormalities in elderly patients occurred at rates similar to those in younger patients. No dose adjustment is required in elderly patients.
ADVERSE DRUG REACTION OVERVIEW
Worldwide, over 3 094 patients have been treated with rabeprazole sodium in Phase II-III clinical trials involving various dosages and durations of treatment. In general, rabeprazole treatment has been well tolerated in both short-term and long-term trials.
CLINICAL TRIAL ADVERSE DRUG REACTIONS
Because clinical trials are conducted under very specific conditions the adverse reaction rates observed in the clinical trials may not reflect the rates observed in practice and should not be compared to the rates in the clinical trials of another drug. Adverse drug reaction information from clinical trials is useful for identifying drug-related adverse events and for approximating rates.
Incidence in North American and European Clinical Trials
The following adverse events were reported by the treating physicians to have a possible or probable relationship to drug in at least 1% of patients treated with rabeprazole sodium compared to patients who received placebo:

MONITORING AND LABORATORY TESTS
An extensive evaluation of laboratory analyses has not revealed any significant and/or clinically relevant changes during rabeprazole sodium treatment. The following changes in laboratory parameters were reported as adverse events: abnormal platelets, albuminuria, increased creatine phosphokinase, abnormal erythrocytes, hypercholesteremia, hyperglycemia, hyperlipemia, hypokalemia, hyponatremia, leukocytosis, leukorrhea, abnormal liver function tests, prostatic specific antigen increase, urine abnormality, abnormal WBC. In controlled clinical studies, 3/1 456 (0.2%) patients treated with rabeprazole and 2/237 (0.8%) patients treated with placebo developed treatment-emergent abnormalities (which were either new on study or present at study entry with an increase of 1.25 x baseline value) in SGOT (AST), SGPT (ALT), or both. None of the three rabeprazole patients experienced chills, fever, right upper quadrant pain, nausea or jaundice.
POSTMARKET ADVERSE DRUG REACTIONS
Additional adverse events reported from worldwide marketing experience with rabeprazole sodium are: sudden death, coma and hyperammonemia, jaundice, rhabdomyolysis, disorientation and delirium, anaphylaxis, angioedema, bullous and other drug eruptions of the skin, interstitial pneumonia, TSH elevations, myalgia and arthralgia. In most instances, the relationship to rabeprazole sodium was unclear. There have also been rare reports of increased hepatic enzymes and rare reports of hepatitis. Rare reports of hepatic encephalopathy have been received in patients with underlying cirrhosis. In addition, agranulocytosis, hemolytic anemia, leukopenia, pancytopenia, thrombocytopenia, neutropenia and acute systemic allergic reactions (facial swelling, hypotension, dyspnea) have been reported. There have been very rare reports of interstitial nephritis, gynecomastia, erythema multiforme, toxic epidermal necrolysis and Stevens Johnson syndrome.
Rabeprazole is metabolized by the cytochrome P450 (CYP450) drug metabolizing system. Studies in healthy subjects have shown that rabeprazole does not have clinically significant interactions with other drugs metabolized by the CYP450 system, such as warfarin, phenytoin, theophylline or diazepam. Steady state interactions of rabeprazole and other drugs metabolized by this enzyme system have not been studied in patients. Studies with rabeprazole in humans reveal no inhibition or activation of the CYP450 system of the liver. There have been reports of increased INR and prothrombin time in patients receiving proton pump inhibitors, including rabeprazole and warfarin concomitantly. Increases in INR and prothrombin time may lead to abnormal bleeding and even death. In vitro incubations employing human liver microsomes indicated that the degree of inhibition of cyclosporin metabolism by rabeprazole and omeprazole is similar at equivalent concentrations. Rabeprazole produces sustained inhibition of gastric acid secretion. An interaction with compounds whose absorption depends on gastric pH may occur due to the magnitude of acid suppression seen with rabeprazole: consequently, the coadministration of ketoconazole and rabeprazole decreases the absorption of ketoconazole, thereby decreasing plasma levels, whereas the concomitant use of digoxin results in an increase in digoxin plasma levels. Therefore, patients may need to be monitored when such drugs are taken concomitantly with rabeprazole.
Taking rabeprazole with food or antacids produced no clinically relevant changes in plasma rabeprazole concentrations.
The recommended adult oral dose is 20 mg once daily. In most patients, healing occurs in four weeks. For patients not healed after this initial course, an additional four weeks of treatment is recommended. Symptom relief is usually rapid. If symptom relief is not achieved after four weeks, further investigation is recommended (see INDICATIONS AND CLINICAL USE).
10 mg once daily has been demonstrated to be effective versus placebo in the maintenance of healing of GERD. The maximum recommended adult oral dose is 20 mg once daily (see INDICATIONS AND CLINICAL USE).
The recommended adult oral dose is 10 mg once daily to a maximum of 20 mg once daily in patients with NERD. If symptom control is not achieved after four weeks, further investigation is recommended (see INDICATIONS AND CLINICAL USE).
The recommended adult oral dose is 20 mg once daily for up to four weeks (see INDICATIONS AND CLINICAL USE). Most patients with duodenal ulcer heal within four weeks but a few patients may require additional therapy to achieve healing. Symptom relief is usually rapid with improvement achieved after two weeks for most patients.
The recommended adult oral dose is 20 mg once daily for up to six weeks (see INDICATIONS AND CLINICAL USE). Most patients with gastric ulcer heal within six weeks, but a few patients may require additional therapy to achieve healing. Symptom relief is usually rapid with improvement achieved after three weeks for most patients.
The Sandoz Rabeprazole dosage in patients with pathologic hypersecretory conditions varies with the individual patient. The recommended adult oral starting dose is 60 mg once a day. Doses should be adjusted to individual patient needs and should continue for as long as clinically indicated. Some patients may require divided doses. Doses up to 100 mg QD and 60 mg BID have been administered. Some patients with Zollinger-Ellison syndrome have been treated continuously with Sandoz Rabeprazole tablets for up to one year. No dosage adjustment is necessary in patients with renal insufficiency or in elderly patients. For patients with severe liver disease, dosage adjustment should be considered.
Sandoz Rabeprazole tablets can be taken with meals or on an empty stomach. Sandoz Rabeprazole tablets are enteric-coated and therefore should be swallowed whole with a beverage (not chewed or crushed).
There has been no experience with large overdoses of rabeprazole although seven reports of accidental overdosage with rabeprazole have been received. The maximum established exposure has not exceeded 60 mg twice daily or 160 mg once daily. Effects are generally minimal, representative of the known adverse event profile, and reversible without any further medical intervention. No specific antidote for rabeprazole is known; in the event of overdosage, treatment should be symptomatic and supportive. Rabeprazole is extensively protein-bound and is not readily dialyzable. For management of a suspected overdose, contact your regional Poison Control Centre.
Sandoz Rabeprazole (rabeprazole sodium) is an antisecretory compound (substituted benzimidazole proton pump inhibitor) that suppresses gastric acid secretion by inhibiting the gastric H+, K+-ATPase at the secretory surface of the gastric parietal cell. Because this enzyme is regarded as the acid (proton) pump within the parietal cell, Sandoz Rabeprazole (rabeprazole sodium) has been characterized as a gastric proton pump inhibitor. Sandoz Rabeprazole (rabeprazole sodium) blocks the final step of gastric acid secretion and produces dose-related sustained inhibition of both basal and stimulated gastric acid secretion.
The antisecretory effect begins within one hour after oral administration of rabeprazole sodium tablets (20 mg), and reaches its maximum within two to four hours. The median inhibitory effect of rabeprazole sodium on 24-hour gastric acidity is 88% of maximal after the first dose and the inhibition of acid secretion increases with repeated once-daily dosing to steady state within seven days. Rabeprazole sodium 20 mg, versus placebo, inhibits basal and pentagastrin-induced acid secretion by 86% and 95%, respectively. At this dosage, it also increases the percentage of time (from 10% to 65%) within a 24-hour period that the gastric pH >3 (see Table 1.3). This relatively prolonged pharmacodynamic action compared to the short pharmacokinetic half-life (approximately one hour) reflects the sustained inactivation of the H+, K+-ATPase.

(1) Gastric pH was measured every hour over a 24-hour period.
In patients with gastroesophageal reflux disease (GERD) and moderate to severe esophageal acid exposure, rabeprazole sodium doses of 20 or 40 mg/day normalized 24-hour esophageal acid exposure. After seven days' treatment, the percentage of time that the esophageal pH <4 was 5.1% at the 20 mg dose and 2.0% at the 40 mg dose, from baselines of 24.7% and 23.7%, respectively. Normalization of 24-hour intraesophageal acid exposure was correlated to gastric pH >4 for at least 35% of the 24-hour period; this level was achieved in 90% of subjects receiving a 20 mg rabeprazole sodium dose and in 100% of subjects receiving a 40 mg rabeprazole sodium dose. With rabeprazole sodium doses of 20 or 40 mg/day, effects on gastric and esophageal pH were significant and substantial after one day of treatment and more pronounced after seven days of treatment.
In patients given daily doses of rabeprazole sodium tablets for up to eight weeks to treat ulcerative or erosive esophagitis and in patients treated for up to 52 weeks to prevent recurrence of disease, there was a dose-related increase in the median fasting gastrin level. The group median values stayed within the normal range. These data are indicative of dose- dependent inhibition on gastric acid secretion by rabeprazole sodium.
Increased serum gastrin secondary to antisecretory agents stimulates proliferation of gastric ECL cells which, over time, may result in ECL cell hyperplasia in laboratory rats and mice and gastric carcinoids in laboratory rats. During life-time exposure of rats with doses of rabeprazole up to 120 mg/kg/day [60 times the exposure on a body surface (mg/m2) basis in patients given the recommended 20 mg/day (12.3 mg/m2) dose], ECL cell hyperplasia was observed in both male and female rats, while gastric carcinoids were observed in female Sprague Dawley rats only. ECL cell hyperplasia was observed with rabeprazole in both male and female rats and mice. Human gastric biopsy specimens from the antrum and the fundus from 330 patients receiving rabeprazole treatment for up to 8 weeks detected no consistent pattern of changes in ECL cell histology. Histological findings from 61 patients receiving rabeprazole also showed no consistent pattern of changes in degree of gastritis. No chronic atrophic gastritis was found in these patients either at baseline or endpoint assessment. In over 400 patients undergoing rabeprazole sodium treatment (10 or 20 mg/day) for up to one year, the incidence of ECL cell hyperplasia was low and comparable to that observed with omeprazole (20 mg/day); no patient demonstrated the adenomatoid changes or carcinoid tumour as observed in rats.
Studies in humans for up to one year have revealed no clinically significant effects on the endocrine system. In healthy male volunteers treated with rabeprazole sodium tablets for 13 days, no clinically relevant changes have been detected in the following endocrine parameters examined: 17 b-estradiol, thyroid-stimulating hormone, triiodothyronine, thyroxine, thyroxine-binding protein, parathyroid hormone, insulin, glucagon, renin, aldosterone, follicle-stimulating hormone, luteotrophic hormone, prolactin, somatotrophic hormone, dehydroepiandrosterone, cortisol-binding globulin, urinary 6 b-hydroxycortisol, and testosterone.
In humans treated with rabeprazole sodium for up to one year, no systemic effects have been observed on the central nervous system, lymphoid, hematopoietic, renal, hepatic, cardiovascular, ocular, or respiratory systems.
Rabeprazole sodium tablets are enteric-coated. Absorption is rapid following ingestion. After oral administration of 20 mg rabeprazole sodium, peak plasma concentrations (Cmax) are reached at an average of 1.6-5.0 hours; bioavailability compared to intravenous administration is 52%. Rabeprazole does not accumulate and its pharmacokinetics are not altered by multiple dosing. The plasma half-life is approximately one hour. Absorption: Following oral administration, rabeprazole is rapidly absorbed and can be detected in plasma as early as 0.5 hours. The rabeprazole Cmax and AUC are linear with doses from 10 mg to 40 mg. Taking rabeprazole sodium tablets with food does not alter Cmax or AUC relative to the fasting state; the Tmax is increased by 1.7 hours. Antacids do not significantly affect the absorption of rabeprazole sodium. Administration of rabeprazole sodium with a high fat meal may delay its absorption by approximately 4 hours or longer; however, the Cmax and the extent of absorption (AUC) are not altered.
Rabeprazole is 96.3% bound to human plasma proteins.
In humans the thioether and carboxylic acid are the main plasma metabolites. These metabolites were not observed to have significant antisecretory activity. The sulphone, desmethyl-thioether and mercapturic acid conjugate minor metabolites were observed at lower levels. Only the desmethyl metabolite has a small amount of antisecretory activity, but it is not present in plasma.
In vitro
studies have demonstrated that rabeprazole is metabolized primarily by non- enzymatic reduction to form the thioether metabolite. Rabeprazole is also metabolized in the liver by cytochromes P450 3A (CYP3A), to a sulphone metabolite, and cytochrome P450 2C19 (CYP2C19), to desmethyl rabeprazole. CYP2C19 exhibits a known genetic polymorphism due to its deficiency in some subpopulations (e.g. 3 to 5% of Caucasians and 17 to 20% of Asians). Rabeprazole metabolism is slow in these subpopulations; therefore, they are referred to as poor metabolizers of the drug.
Excretion: Following a single 20 mg 14C-labelled oral dose of rabeprazole sodium, no unchanged drug was excreted in the urine. Approximately 90% of the dose was eliminated in urine mainly as two metabolites: a mercapturic acid conjugate and a carboxylic acid; there are also two unknowns. The remainder of the dose was recovered in feces.
The pharmacokinetic profile of rabeprazole sodium in adolescents and children under the age of 18 years has not been studied.
Geriatrics: In 20 healthy elderly subjects given a 20 mg dose once daily for seven days, AUC doubled and the Cmax increased by 60% compared to measurements in a parallel younger control group. There was no evidence of drug accumulation (see WARNINGS AND PRECAUTIONS).
See
section.
Hepatic Insufficiency: In two studies in which 23 patients with varying degrees of chronic compensated hepatic cirrhosis were given a 20 mg rabeprazole sodium dose, the AUC of rabeprazole approximately doubled and the Cmax increased by 50% compared to measurements in healthy age- and sex-matched subjects. Renal Insufficiency: In 10 patients with stable end-stage renal failure requiring maintenance hemodialysis (creatinine clearance <=5 mL/min/1.73 m2), the pharmacokinetics of rabeprazole (rabeprazole sodium 20 mg oral dose) were comparable to those in 10 healthy volunteers.
