Description

11 DESCRIPTION The active ingredient in Esomeprazole Sodium for Injection is ( S )-5-methoxy-2[[(4-methoxy-3,5-dimethyl-2-pyridinyl)-methyl]sulfinyl]-1 H -benzimidazole sodium, a PPI. Esomeprazole is the S-isomer of omeprazole, which is a mixture of the S- and R-isomers. Its empirical formula is C 17 H 18 N 3 O 3 SNa with molecular weight of 367.4 g/mol (sodium salt) and 345.4 g/mol (parent compound). Esomeprazole sodium is very soluble in water and freely soluble in ethanol (95%). The structural formula is: Esomeprazole sodium for injection is supplied as a sterile, lyophilized, white to off-white, porous cake or powder in a 5 mL single-dose vial, intended for intravenous administration after reconstitution with 0.9% Sodium Chloride Injection, USP; Lactated Ringer’s Injection, USP or 5% Dextrose Injection, USP. Esomeprazole sodium for injection contains esomeprazole sodium 21.3 mg or 42.5 mg equivalent to esomeprazole 20 mg or 40 mg, edetate disodium 1.5 mg and sodium hydroxide q.s. for pH adjustment. The pH of reconstituted solution of esomeprazole sodium for injection depends on the reconstitution volume and is in the pH range of 9 to 11. The stability of esomeprazole sodium in aqueous solution is strongly pH dependent. The rate of degradation increases with decreasing pH. esomeprazole-spl-structure

( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Gland Pharma at 864-879-9994 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch . 6.1 Clinical Trials Experience Because clinical trials are conducted under widely 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. Symptomatic GERD and EE Adults The safety of esomeprazole sodium is based on results from clinical trials conducted in four different populations including healthy subjects (n=204) and patients with bleeding gastric or duodenal ulcers (n=375). The data described below reflect exposure to esomeprazole sodium in 359 patients in actively-controlled trials: symptomatic GERD with or without a history of EE (n=199) and patients with EE (n=160). The population was 18 to 77 years of age; 45% Male, 52% Caucasian, 17% Black, 3% Asian, and 28% other race. Most patients received doses of either 20 or 40 mg either as an infusion or an injection. Adverse reactions occurring in at least 1% of patients are listed below in Table 3. Table 3: Adverse Reactions 1 in the Esomeprazole Sodium Group in Active Controlled Trials of Symptomatic GERD with or without EE Adverse Reactions % of patients Esomeprazole Sodium (n=359) Headache 11 Flatulence 10 Nausea 6 Abdominal pain 6 Diarrhea 4 Mouth dry 4 Dizziness/vertigo 3 Constipation 3 Injection site reaction 2 Pruritus 1 1 Incidence of at least 1% in the esomeprazole sodium group Intravenous treatment with esomeprazole 20 and 40 mg administered as an injection or as an infusion was found to have a safety profile similar to that of oral esomeprazole. Pediatrics A randomized, open-label, multi-national study to evaluate the pharmacokinetics of repeated intravenous doses of once daily esomeprazole in pediatric patients 1 month to 17 years old, inclusive was performed [see Clinical Pharmacology (12.3) ]. The safety results are consistent with the known safety profile of esomeprazole and no unexpected safety signals were identified. Risk Reduction of Rebleeding of Gastric or Duodenal Ulcers in Adults The data described in Table 4 below reflect exposure to esomeprazole sodium in 375 patients who presented with endoscopically confirmed gastric or duodenal ulcer bleeding in a placebo-controlled trial. The population was 18 to 98 years old; 68% Male, 87% Caucasian, 1% Black, 7% Asian, and 4% other race. Following endoscopic hemostasis, patients received either placebo or 80 mg esomeprazole sodium as an intravenous infusion over 30 minutes followed by a continuous infusion of 8 mg/hour for a total treatment duration of 72 hours. After the initial 72-hour period, all patients received an oral PPI for 27 days.

    • Drug Interactions

    7 DRUG INTERACTIONS Tables 5 and 6 include drugs with clinically important drug interactions and interaction with diagnostics when administered concomitantly with esomeprazole and instructions for preventing or managing them. Consult the labeling of concomitantly used drugs to obtain further information about interactions with PPIs. Table 5: Clinically Relevant Interactions Affecting Drugs Co-Administered with Esomeprazole and Interaction with Diagnostics Antiretrovirals Clinical Impact: The effect of PPIs on antiretroviral drugs is variable. The clinical importance and the mechanisms behind these interactions are not always known. Decreased exposure of some antiretroviral drugs (e.g., rilpivirine atazanavir, and nelfinavir) when used concomitantly with esomeprazole may reduce antiviral effect and promote the development of drug resistance [see Clinical Pharmacology (12.3) ]. Increased exposure of other antiretroviral drugs (e.g., saquinavir) when used concomitantly with esomeprazole may increase toxicity [see Clinical Pharmacology (12.3) ]. There are other antiretroviral drugs which do not result in clinically relevant interactions with esomeprazole. Intervention: Rilpivirine-containing products : Concomitant use with esomeprazole sodium is contraindicated [see Contraindications (4) ] . Atazanavir : See prescribing information for atazanavir for dosing information. Nelfinavir : Avoid concomitant use with esomeprazole sodium. See prescribing information for nelfinavir. Saquinavir : See the prescribing information for saquinavir for monitoring of potential saquinavir-related toxicities. Other antiretrovirals : See prescribing information for specific antiretroviral drugs Warfarin Clinical Impact: Increased INR and prothrombin time in patients receiving PPIs, including esomeprazole, and warfarin concomitantly. Increases in INR and prothrombin time may lead to abnormal bleeding and even death. Intervention: Monitor INR and prothrombin time and adjust the dose of warfarin, if needed, to maintain the target INR range. Methotrexate Clinical Impact: Concomitant use of esomeprazole with methotrexate (primarily at high dose) may elevate and prolong serum concentrations of methotrexate and/or its metabolite hydroxymethotrexate, possibly leading to methotrexate toxicities. No formal drug interaction studies of high-dose methotrexate with PPIs have been conducted [see Warnings and Precautions (5.11) ]. Intervention: A temporary withdrawal of esomeprazole sodium may be considered in some patients receiving high-dose methotrexate. 2C19 Substrates (e.g., clopidogrel, citalopram, cilostazol, diazepam) Clopidogrel Clinical Impact: Concomitant use of esomeprazole 40 mg resulted in reduced plasma concentrations of the active metabolite of clopidogrel and a reduction in platelet inhibition [see Clinical Pharmacology (12.3) ]. There are no adequate combination studies of a lower dose of esomeprazole or a higher dose of clopidogrel in comparison with the approved...

    Contraindications

    4 CONTRAINDICATIONS

  • Esomeprazole sodium is contraindicated in patients with known hypersensitivity to substituted benzimidazoles or to any component of the formulation.

  • Patients receiving rilpivirine-containing products. ( 4 , 7 )

    • Pregnancy and Breastfeeding

    8.1 Pregnancy Risk Summary There are no adequate and well-controlled studies with esomeprazole in pregnant women. Esomeprazole is the s-isomer of omeprazole. Available epidemiologic data fail to demonstrate an increased risk of major congenital malformations or other adverse pregnancy outcomes with first trimester omeprazole use. Reproduction studies in rats and rabbits resulted in dose-dependent embryo-lethality at omeprazole doses that were approximately 3.4 to 34 times an oral human dose of 40 mg (based on a body surface area for a 60 kg person). Teratogenicity was not observed in animal reproduction studies with administration of oral esomeprazole magnesium in rats and rabbits with doses about 68 times and 42 times, respectively, an oral human dose of 40 mg (based on a body surface area basis for a 60 kg person). Changes in bone morphology were observed in offspring of rats dosed through most of pregnancy and lactation at doses equal to or greater than approximately 34 times an oral human dose of 40 mg. When maternal administration was confined to gestation only, there were no effects on bone physeal morphology in the offspring at any age (see Data). The estimated background risks of major birth defects and miscarriage for the indicated population are unknown. All pregnancies have a background risk of birth defect, loss or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. Data Human Data Esomeprazole is the S-isomer of omeprazole. Four epidemiological studies compared the frequency of congenital abnormalities among infants born to women who used omeprazole during pregnancy with the frequency of abnormalities among infants of women exposed to H 2 -receptor antagonists or other controls. A population based retrospective cohort epidemiological study from the Swedish Medical Birth Registry, covering approximately...

    Overdosage

    10 OVERDOSAGE The symptoms described in connection with deliberate esomeprazole overdose (limited experience of doses in excess of 240 mg/day) are transient. Reports of overdosage with omeprazole in humans may also be relevant. Doses ranged up to 2,400 mg (120 times the usual recommended clinical dose). Manifestations were variable, but included confusion, drowsiness, blurred vision, tachycardia, nausea, diaphoresis, flushing, headache, dry mouth, and other adverse reactions similar to those seen at recommended dosages. See the full prescribing information for oral omeprazole for complete safety information. No specific antidote for esomeprazole is known. Since esomeprazole is extensively protein bound, it is not expected to be removed by dialysis. 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.
