Rabeprazole
/api/v1/drug/rabeprazoleMechanism of action
Sourced from openFDARabeprazole belongs to a class of antisecretory compounds (substituted benzimidazole proton-pump inhibitors) that do not exhibit anticholinergic or histamine H 2 -receptor antagonist properties, but suppress 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, rabeprazole has been characterized as a gastric proton-pump inhibitor.

Warnings & precautions
Sourced from openFDAGastric Malignancy : In adults, symptomatic response to therapy with rabeprazole does not preclude the presence of gastric malignancy. Consider additional follow-up and diagnostic testing ( 5.1 ). Use with Warfarin : Monitor for increases in INR and prothrombin time ( 5.2 , 7 ). Acute Tubulointerstitial Nephritis : Discontinue treatment and evaluate patients ( 5.3 ). Clostridium difficile- Associated Diarrhea : PPI therapy may be associated with increased risk of ( 5.4 ). Bone Fracture : Long-term and multiple daily dose PPI therapy may be associated with an increased risk for osteoporosis-related fractures of the hip, wrist, or spine ( 5.5 ). Severe Cutaneous Adverse Reactions : Discontinue at the first signs or symptoms of severe cutatneous adverse reactions or other signs of hypersensitivity and consider further evaluation ( 5.6 ). Cutaneous and Systemic Lupus Erythematosus : Mostly cutaneous, new onset or exacerbation of existing disease; discontinue rabeprazole sodium delayed-release tablets and refer to specialist for evaluation ( 5.7 ). Cyanocobalamin (Vitamin B-12) Deficiency : Daily long-term use (e.g., longer than 3 years) may lead to malabsorption or a deficiency of cyanocobalamin ( 5.8 ). Hypomagnesemia and Mineral Metabolism : Reported rarely with prolonged treatment with PPIs ( 5.9 ). Interaction with Methotrexate : Concomitant use with PPIs may elevate and/or prolong serum concentrations of methotrexate and/or its metabolite, possibly leading to toxicity.
Adverse reactions
Sourced from openFDAMost common adverse reactions in adults (>2%) are pain, pharyngitis, flatulence, infection, and constipation ( 6.1 ). Most common adverse reactions in adolescents (≥2%) are headache, diarrhea, nausea, vomiting, and abdominal pain ( 6.1 ). To report SUSPECTED ADVERSE REACTIONS, contact Torrent Pharma Inc. at 1-800-912-9561 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch The following serious adverse reactions are described below and elsewhere in labeling: Acute Tubulointerstitial Nephritis [see Warnings and Precautions ( 5.3 )] Clostridium difficile- Associated Diarrhea [see Warnings and Precautions ( 5.4 )] Bone Fracture [see Warnings and Precautions ( 5.5 )] Cutaneous and Systemic Lupus Erythematosus [ see Warnings and Precautions ( 5.7 ) ] Cyanocobalamin (Vitamin B-12) Deficiency [see Warnings and Precautions ( 5.8 )] Hypomagnesemia and Mineral Metabolism [see Warnings and Precautions ( 5.9 )] Fundic Gland Polyps [see Warnings and Precautions ( 5.11 )] 6.1 Clinical Studies Experience Because clinical trials are conducted under varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. Adults The data described below reflect exposure to rabeprazole sodium delayed-release tablets in 1,064 adult patients exposed for up to 8 weeks. The studies were primarily placebo- and active-controlled trials in adult patients with Erosive or Ulcerative Gastroesophageal Reflux Disease (GERD), Duodenal Ulcers and Gastric Ulcers.
Use in specific populations
Sourced from openFDAPediatric Use : Dosage strength not appropriate for patients less than 12 years ( 2 , 8.4 ). 8.1 Pregnancy Risk Summary There are no available human data on rabeprazole sodium delayed-release tablets use in pregnant women to inform the drug associated risk. The background risk of major birth defects and miscarriage for the indicated populations are unknown. However, the background risk in the U.S. general population of major birth defects is 2 to 4% and of miscarriage is 15 to 20% of clinically recognized pregnancies. No evidence of adverse developmental effects were seen in animal reproduction studies with rabeprazole administered during organogenesis at 13 and 8 times the human area under the plasma concentration-time curve (AUC) at the recommended dose for GERD, in rats and rabbits, respectively [see Data] . Changes in bone morphology were observed in offspring of rats treated with oral doses of a different PPI through most of pregnancy and lactation. When maternal administration was confined to gestation only, there were no effects on bone physeal morphology in the offspring at any age [ see Data] .
Pharmacokinetics
Sourced from openFDA- Metabolism
- After oral administration of 20 mg rabeprazole sodium delayed-release tablets, peak plasma concentrations (C max ) of rabeprazole occur over a range of 2 to 5 hours (T max ). The rabeprazole C max and AUC are linear over an oral dose range of 10 mg to 40 mg.
Overdosage
Sourced from openFDASeven reports of accidental overdosage with rabeprazole have been received. The maximum reported overdose was 80 mg. There were no clinical signs or symptoms associated with any reported overdose. Patients with Zollinger-Ellison syndrome have been treated with up to 120 mg rabeprazole once daily. No specific antidote for rabeprazole is known. Rabeprazole is extensively protein bound and is not readily dialyzable. In the event of overdosage, treatment should be symptomatic and supportive. If over-exposure occurs, call your Poison Control Center at 1-800-222-1222 for current information on the management of poisoning or overdosage.
