Esomeprazole Dosage and Administration

Administration

Administer orally or IV.1 34

Oral Administration

Administer esomeprazole capsules and oral suspension orally at least 1 hour before a meal.1 Administer esomeprazole/naproxen fixed-combination tablets at least 30 minutes before a meal.342 (See Food under Pharmacokinetics.)

Antacids may be used concomitantly as needed for pain relief.1

Capsules

Swallow capsules intact; do not chew or crush.1

Alternatively, open capsule and mix contents with 1 tablespoon applesauce; swallow immediately without chewing.1 Applesauce should not be hot and should be soft enough to swallow without chewing.1

Powder for Oral Suspension

Mix contents of 2.5- or 5-mg packet with 5 mL of water.1

Mix contents of 10-, 20-, or 40-mg packet with 15 mL of water.1

If a single dose requires 2 packets, reconstitute oral suspension with twice the water needed for 1 packet.1

After mixing suspension with appropriate amount of water, allow mixture to thicken for 2–3 minutes.1 Stir mixture and consume within 30 minutes of preparation.1 If any drug mixture remains in container after ingestion, mix with additional water and ingest immediately.1

NG Tube

May administer suspension prepared from opened capsules through NG tube; may administer suspension prepared from powder for oral suspension through NG tube or gastric tube (6 French or larger).1

Capsules: Open capsule, empty intact granules into 60-mL catheter-tipped syringe, and mix with 50 mL of water.1 Replace plunger and shake well for 15 seconds.1 Hold syringe with tip upright and check tip for remaining granules.1 Administer immediately through NG tube; flush with additional water.1 Do not administer if pellets have dissolved or disintegrated.1

Powder for oral suspension: Mix contents of 2.5- or 5-mg packet with 5 mL of water and contents of 10-, 20-, or 40-mg packet with 15 mL of water in a catheter-tipped syringe; shake immediately, then allow mixture to thicken for 2–3 minutes.1 Shake syringe and administer through NG or gastric tube (6 French or larger) within 30 minutes of preparation.1 Refill syringe with additional water (5 or 15 mL, respectively) and flush NG or gastric tube.1

Detailed Esomeprazole dosage information

Cautions for Esomeprazole

Contraindications

Warnings/Precautions

Sensitivity Reactions

Hypersensitivity Reactions

Hypersensitivity reactions (e.g., angioedema, anaphylactic shock) reported.1 34

Gastric Malignancy

Response to esomeprazole does not preclude presence of occult gastric neoplasm.1 34

Atrophic Gastritis

Atrophic gastritis reported occasionally with long-term omeprazole use.1 34

Clostridium difficile Infection

Proton-pump inhibitors associated with possible increased (1.4–2.75 times) risk of Clostridium difficile infection, including C. difficile-associated diarrhea and colitis (CDAD; also known as antibiotic-associated diarrhea and colitis or pseudomembranous colitis).335 336 339 340 Many patients also had other risk factors for CDAD.335 May be severe; colectomy and, rarely, death reported.335

Use the lowest effective dosage and shortest duration of therapy appropriate for the patient's clinical condition.335

Consider CDAD if persistent diarrhea develops and manage accordingly; initiate supportive therapy (e.g., fluid and electrolyte management), anti-infective therapy directed against C. difficile (e.g., metronidazole, vancomycin), and surgical evaluation as clinically indicated.335 336

Bone Fracture

Several observational studies suggest that use of proton-pump inhibitors, particularly in high dosages (i.e., multiple daily doses) and/or for prolonged periods of time (i.e., ≥1 year), may be associated with increased risk of osteoporosis-related fractures of the hip, wrist, or spine.1 34 35 300 301 302 303 304 305 Magnitude of risk is unclear;35 300 301 302 303 304 305 310 causality not established.305 FDA is continuing to evaluate this safety concern.305

Use the lowest effective dosage and shortest duration of therapy appropriate for the patient’s clinical condition.1 34 35 301 303 305 307

Individuals at risk for osteoporosis-related fractures should receive an adequate intake of calcium and vitamin D; assess and manage these patients’ bone health according to current standards of care.1 34 35 303 305 307

Hypomagnesemia

Hypomagnesemia, symptomatic and asymptomatic, reported rarely in patients receiving long-term therapy (≥3 months or, in most cases, >1 year) with proton-pump inhibitors, including esomeprazole.1 34 317 318 319 320 321 322 323 324 325 326 327 328 329 330 Serious adverse effects include tetany, seizures, tremors, carpopedal spasm, arrhythmias (e.g., atrial fibrillation, supraventricular tachycardia), and abnormal QT interval.1 34 318 319 321 322 323 325 327 328 329 Paresthesia, muscle weakness, muscle cramps, lethargy, fatigue, and unsteadiness may occur.319 320 321 325 330 Most patients required magnesium replacement and discontinuance of the proton-pump inhibitor.1 34 317 319 321 322 323 324 325 326 327 330 Hypomagnesemia resolved within 1 week (median) following discontinuance and recurred within 2 weeks (median) of rechallenge.327

In patients expected to receive long-term proton-pump inhibitor therapy or in patients currently receiving digoxin or drugs that may cause hypomagnesemia (e.g., diuretics), consider measuring serum magnesium concentrations prior to initiation of prescription proton-pump inhibitor therapy and periodically thereafter.1 34 319 326 327 328 330

Cardiovascular Effects

Preliminary safety data from 2 long-term clinical trials comparing esomeprazole or omeprazole with antireflux surgery in patients with severe GERD raised concerns about a potential increased risk of cardiac events (e.g., MI, heart failure, sudden death) in patients receiving these drugs.36 37 38 After reviewing data from these and other studies, FDA has concluded that long-term use of these drugs is not likely to be associated with an increased risk of such cardiac events.36 37 38 FDA recommends that clinicians continue to prescribe and patients continue to use these drugs in the manner described in the manufacturers’ labelings.36 37 38

Respiratory Effects

Administration of proton-pump inhibitors has been associated with an increased risk for developing certain infections (e.g., community-acquired pneumonia).29 30

Use of Fixed Combinations

When used in fixed combination with naproxen, consider the cautions, precautions, and contraindications associated with naproxen.342

Specific Populations

Pregnancy

Category B.1 34

Lactation

Not known whether esomeprazole is distributed into milk, but omeprazole is distributed into milk.1 34 Discontinue nursing or the drug.1 34

Pediatric Use

Safety and efficacy of oral esomeprazole for short-term (4–8 weeks) treatment of GERD established in pediatric patients 1–17 years of age.1 Adverse effects and pharmacokinetics in children and adolescents similar to those reported in adults.1

Safety and efficacy of oral esomeprazole for short-term (up to 6 weeks) treatment of erosive esophagitis due to acid-mediated GERD established in infants 1 month to <1 year of age.1 Oral esomeprazole was not more effective than placebo in a randomized, controlled, treatment-withdrawal study in infants 1–11 months of age with symptomatic GERD.1 Common adverse effects include irritability and vomiting.1

Efficacy of oral esomeprazole not established in infants <1 month of age.1

Safety and efficacy of IV esomeprazole for short-term treatment of GERD with erosive esophagitis established in pediatric patients 1 month to 17 years of age.34 Adverse effects consistent with the drug's known safety profile.34

Safety and efficacy of IV esomeprazole in neonates <1 month of age not established.34

Geriatric Use

No substantial differences in safety and efficacy relative to younger adults, but increased sensitivity cannot be ruled out.1 34

Hepatic Impairment

Use with caution in patients with severe hepatic impairment.1 20 (See Hepatic Impairment under Dosage and Administration.)

Common Adverse Effects

Oral: Headache, diarrhea, nausea, flatulence, abdominal pain, constipation, dry mouth.1 19

IV: Similar adverse effects as oral esomeprazole; also injection site reaction, dizziness/vertigo, pruritus.34

Drug Interactions

Extensively metabolized by CYP isoenzymes, principally CYP2C19; also to lesser extent by CYP3A4.1 19 34 May inhibit CYP2C19; unlikely to inhibit CYP3A4, 1A2, 2A6, 2C9, 2D6, or 2E1.1 34

Drugs Metabolized by Hepatic Microsomal Enzymes

Potential to inhibit metabolism of drugs metabolized by CYP2C19.1 34 Interaction unlikely with drugs metabolized by other CYP isoenzymes.1 34

Drugs Affecting Hepatic Microsomal Enzymes

Combined inhibitors of CYP2C19 and CYP3A4: Potential pharmacokinetic interaction (increased esomeprazole exposure); esomeprazole dosage adjustment usually not required but may be considered in patients receiving high dosages (up to 240 mg daily), such as those with Zollinger-Ellison syndrome.1 34

Inducers of CYP2C19 and/or CYP3A4: Potential pharmacokinetic interaction (decreased esomeprazole concentrations).1 34

Drugs that Cause Hypomagnesemia

Potential pharmacologic interaction (possible increased risk of hypomagnesemia).327 Consider monitoring magnesium concentrations prior to initiation of prescription proton-pump inhibitor therapy and periodically thereafter.1 34 327 (See Hypomagnesemia under Cautions.)

Specific Drugs and Laboratory Tests

Drug or Test

Interaction

Comments

Amoxicillin

Pharmacokinetic interaction unlikely1 34

Atazanavir

Possible altered oral absorption of atazanavir, resulting in decreased plasma atazanavir concentrations; possible loss of virologic response and development of drug resistance1 31 34

Manufacturer of esomeprazole states that concomitant administration with atazanavir is not recommended1 34

Antiretroviral treatment-naive patients: If a proton-pump inhibitor is used concomitantly with atazanavir, administer ritonavir-boosted atazanavir (atazanavir 300 mg and ritonavir 100 mg once daily with food); administer the proton-pump inhibitor approximately 12 hours before ritonavir-boosted atazanavir31 32

For treatment-naive patients, dosage of proton-pump inhibitor should not exceed omeprazole 20 mg daily (or equivalent)31 32

Antiretroviral treatment-experienced patients: Concomitant use of proton-pump inhibitors with atazanavir not recommended31 32

Cilostazol

Possible increased concentrations of cilostazol and its active metabolite1 34

Consider reducing cilostazol dosage (from 100 mg twice daily to 50 mg twice daily)1 34

Clarithromycin

Increased plasma concentrations of esomeprazole and 14-hydroxyclarithromycin 1

Not considered clinically important1 34 316

Clopidogrel

Esomeprazole (or omeprazole) reduces exposure to clopidogrel's active metabolite and decreases platelet inhibitory effects;44 224 225 228 232 233 236 350 additional data needed to fully elucidate potential clinical consequences (e.g., increased cardiovascular events)40 41 42 44 45 224 225 228 229 230 235 236 237 238 240 311

Dexlansoprazole, lansoprazole, or pantoprazole had less effect on clopidogrel's antiplatelet activity than did omeprazole or esomeprazole224 350 351

Avoid concomitant use of esomeprazole (or omeprazole) and clopidogrel224

Assess risks and benefits of concomitant proton-pump inhibitor and clopidogrel use in individual patients312 313 314 315 316

American College of Cardiology Foundation/American College of Gastroenterology/American Heart Association (ACCF/ACG/AHA) states that GI bleeding risk reduction with concomitant proton-pump inhibitor in patients with risk factors for GI bleeding (e.g., advanced age; concomitant use of warfarin, corticosteroids, or NSAIAs; H. pylori infection) may outweigh potential reduction in cardiovascular efficacy of antiplatelet treatment associated with a drug-drug interaction.311 In patients without such risk factors, ACCF/ACG/AHA states that risk/benefit balance may favor use of antiplatelet therapy without a proton-pump inhibitor.311

If concomitant therapy with a proton-pump inhibitor and clopidogrel is deemed necessary, consider using an agent with little or no CYP2C19-inhibitory activity;44 45 46 224 230 350 alternatively, consider using a histamine H2-receptor antagonist (ranitidine, famotidine, nizatidine)44 45 230 but not cimetidine (also a potent CYP2C19 inhibitor)232 233

Diazepam

Decreased diazepam metabolism and increased plasma concentrations1 34

Not considered clinically important1 34

Digoxin

Hypomagnesemia (e.g., resulting from long-term use of proton-pump inhibitors) sensitizes the myocardium to digoxin and, thus, may increase risk of digoxin-induced cardiotoxic effects327 331

See table entry for gastric pH-dependent drugs

Consider monitoring magnesium concentrations prior to initiation of prescription proton-pump inhibitor therapy and periodically thereafter1 327

Diuretics (i.e., loop or thiazide diuretics)

Possible increased risk of hypomagnesemia327

Consider monitoring magnesium concentrations prior to initiation of prescription proton-pump inhibitor therapy and periodically thereafter1 327

Fosamprenavir

Fosamprenavir: Increased esomeprazole AUC; no substantial effect on concentrations of amprenavir (active metabolite of fosamprenavir)345

Ritonavir-boosted fosamprenavir: No substantial effect on amprenavir or esomeprazole concentrations345

Fosamprenavir (with or without ritonavir): No dosage adjustment required32 345

Gastric pH-dependent drugs (e.g., atazanavir, digoxin, erlotinib, iron salts, ketoconazole)

Atazanavir, erlotinib, iron salts, ketoconazole: Possible decreased absorption1 34

Digoxin: Possible increased exposure1 34

Digoxin: May need to monitor for manifestations of digoxin toxicity1 34

Lopinavir

Lopinavir/ritonavir: Omeprazole had no clinically important effect on lopinavir plasma concentrations or AUC32 344

No dosage adjustment required when proton-pump inhibitors used with lopinavir/ritonavir32

Methotrexate

Possible delayed clearance and increased serum concentrations of methotrexate and/or its metabolite hydroxymethotrexate; possible methotrexate toxicity1 34 333 334

Reported mainly with high-dose methotrexate (300 mg/m2 to 12 g/m2),1 34 333 but also reported with low dosages (e.g., 15 mg per week)333

Manufacturer of esomeprazole recommends considering temporary discontinuance of proton-pump inhibitor therapy in some patients receiving high-dose methotrexate1 34

Some clinicians recommend withholding the proton-pump inhibitor for several days before and after administration of either high-dose or low-dose methotrexate or, alternatively, substituting a histamine H2-receptor antagonist for the proton-pump inhibitor333 334

Nelfinavir

Omeprazole decreased peak plasma concentrations and AUCs of nelfinavir and its major active metabolite1 34 347

Concomitant use of nelfinavir with proton-pump inhibitors not recommended1 34

NSAIAs (naproxen, rofecoxib)

Pharmacokinetic interaction unlikely1 34

Oral contraceptives

No change in esomeprazole pharmacokinetics1 34

Phenytoin

Pharmacokinetic interaction unlikely1 34

Quinidine

Pharmacokinetic interaction unlikely1 34

Raltegravir

Omeprazole increased peak plasma concentration and AUC of raltegravir32 348

No dosage adjustment recommended when proton-pump inhibitors used with raltegravir32 348

Rifampin

Possible decreased esomeprazole concentrations1 34

Avoid concomitant use1 34

Rilpivirine

Omeprazole decreased plasma concentrations and AUC of rilpivirine32 343

Concomitant use of rilpivirine and proton-pump inhibitors contraindicated32 343

Saquinavir

Ritonavir-boosted saquinavir: Omeprazole increased peak plasma concentration and AUC of saquinavir1 32 34 346

Caution advised if proton-pump inhibitor used with ritonavir-boosted saquinavir; monitor for saquinavir toxicity1 32 34 346

Manufacturer of esomeprazole recommends considering saquinavir dosage reduction on an individual basis1 34

St. John’s wort (Hypericum perforatum)

Possible decreased esomeprazole concentrations1 34

Avoid concomitant use1 34

Sucralfate

Possible delayed proton-pump inhibitor absorption and decreased bioavailability 47

Administer proton-pump inhibitor at least 30 minutes before sucralfate47

Tacrolimus

Possible increased tacrolimus concentrations1 34

Tests for neuroendocrine tumors

Increased serum chromogranin A (CgA) concentrations (secondary to esomeprazole-induced increase in intragastric pH) may produce false-positive results1 34

Temporarily discontinue esomeprazole before assessing CgA concentrations and consider repeating test if initial CgA concentrations are high1 34

Voriconazole

Possible increase in esomeprazole exposure1 34

Esomeprazole dosage adjustment usually not required but may be considered in patients receiving high dosages (up to 240 mg daily), such as those with Zollinger-Ellison syndrome1 34

Warfarin

Potential for decreased warfarin metabolism and changes in prothrombin measures1 34

Monitor PT and INR1 34

Esomeprazole Pharmacokinetics

Absorption

Bioavailability

Delayed-release esomeprazole: Bioavailability is 64% after a single 40-mg oral dose.1 Bioavailability is 90% after repeated oral doses of 40 mg once daily.1

Food

Delayed-release esomeprazole: AUC decreased by 43–53% when a 40-mg oral dose was administered with food.1

Immediate-release esomeprazole/delayed-release naproxen tablets: Administration with high-fat food decreases rate and extent of esomeprazole absorption (peak plasma concentration delayed by 1 hour, AUC decreased 52%, peak concentration decreased 74%).342 Administration 30 minutes before high-fat food does not substantially alter rate or extent of esomeprazole absorption relative to fasted state.342 Administration 1 hour before high-fat food increases esomeprazole AUC and peak concentration by 25 and 50%, respectively, but peak concentration is lower than that observed with labeled dosage of esomeprazole 40 mg daily.342

Special Populations

Following oral dosage of 40 mg once daily in patients with severe (Child-Pugh class C) hepatic impairment, steady-state AUCs were 2–3 times greater than those in patients with normal hepatic function.1 34

Distribution

Extent

Not known whether esomeprazole is distributed into milk, but omeprazole is distributed into milk.1 34 Not known whether esomeprazole crosses the placenta.1 34

97%.1 34

Elimination

Metabolism

Metabolized to inactive metabolites in the liver by CYP isoenzymes, principally by CYP2C19, and to lesser extent by CYP3A4.1 34

Elimination Route

Excreted principally in urine (80% as inactive metabolites, <1% as active drug); remainder in feces as inactive metabolites.1 34

Half-life
