What is Esomeprazole Magnesium?

From the FDA label:The active ingredient in esomeprazole magnesium delayed-release capsules for oral administration is 1H-Benzimidazole,5-methoxy-2-[(S)-[4-methoxy-3,5-dimethyl-2-pyridinyl)methyl]sulfinyl], magnesium salt (2:1), a PPI. Esomeprazole is the S-isomer of omeprazole, which is a mixture of the S- and R- isomers. (Initial U.S. approval of esomeprazole magnesium: 2001). Its molecular formula is C 34 H 36 MgN 6 O 6 S 2 with molecular weight of 713.12 on an anhydrous basis. The structural formula is: The magnesium salt is an off-white to pale cream colored powder. It is slightly soluble in water. The stability of esomeprazole magnesium is a function of pH; it rapidly degrades in acidic media, but it has acceptable stability under alkaline conditions. At pH 6.8 (buffer), the half-life of the magnesium salt is about 19 hours at 25°C and about 8 hours at 37°C. Esomeprazole magnesium is supplied in delayed-release capsules. Each esomeprazole magnesium delayed-release capsule contains 20 mg of esomeprazole (equivalent to 22.25 mg esomeprazole magnesium) or 40 mg of esomeprazole (equivalent to 44.50 mg esomeprazole magnesium) in the form of enteric-coated pellets with the following inactive ingredients: crospovidone, hydroxypropyl cellulose, mannitol, methacrylic acid-ethyl acrylate copolymer dispersion, sucrose, sugar spheres (corn starch and sucrose), talc, titanium dioxide and triethyl…

Warnings

Important safety information

Gastric Malignancy: In adults, symptomatic response does not preclude the presence of gastric malignancy. Consider additional follow-up and diagnostic testing. ( 5.1 ) • Acute Tubulointerstitial Nephritis: Discontinue treatment and evaluate patients. ( 5.2 ) • Clostridium difficile -Associated Diarrhea: PPI therapy may be associated with increased risk. ( 5.3 ) • 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. ( 5.4 ) • Severe Cutaneous Adverse Reactions: Discontinue at the first signs or symptoms of severe cutaneous adverse reactions or other signs of hypersensitivity and consider further evaluation. ( 5.5 ) • Cutaneous and Systemic Lupus Erythematosus: Mostly cutaneous; new onset or exacerbation of existing disease; discontinue esomeprazole magnesium delayed-release capsules and refer to specialist for evaluation. ( 5.6 ) • Interaction with Clopidogrel: Avoid concomitant use of esomeprazole magnesium delayed-release capsules. ( 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 St. John’s Wort or Rifampin: Avoid concomitant use of esomeprazole magnesium delayed-release capsules. ( 5.10 , 7 ) • Interactions with Diagnostic Investigations for Neuroendocrine Tumors: Increased chromogranin A (CgA) levels may interfere with diagnostic investigations for neuroendocrine tumors, temporarily stop esomeprazole magnesium delayed-release capsules at least 14 days before assessing CgA levels. ( 5.11 , 12.2 ) • Interaction with Methotrexate: Concomitant use with PPIs may elevate and/or prolong serum concentrations of methotrexate and/or its metabolite, possibly leading to toxicity. With high dose methotrexate administration, consider temporary withdrawal of esomeprazole magnesium delayed-release capsules. ( 5.12 , 7 ) • Fundic Gland Polyps: Risk increases with long-term use, especially beyond one year. Use the shortest duration of therapy. ( 5.13 ) 5.1 Presence of Gastric Malignancy In adults, symptomatic response to therapy with esomeprazole magnesium delayed-release capsules does not preclude the presence of gastric malignancy. Consider additional follow-up and diagnostic testing in adult patients who have a suboptimal response or an early symptomatic relapse after completing treatment with a PPI. In older patients, also consider an endoscopy. 5.2 Acute Tubulointerstitial Nephritis Acute tubulointerstitial nephritis (TIN) has been observed in patients taking PPIs and may occur at any point during PPI therapy. Patients may present with varying signs and symptoms from symptomatic hypersensitivity reactions to non-specific symptoms of decreased renal function (e.g., malaise, nausea, anorexia). In reported case series, some patients were diagnosed on biopsy and in the absence of extra-renal manifestations (e.g., fever, rash or arthralgia). Discontinue esomeprazole magnesium delayed-release capsules and evaluate patients with suspected acute TIN [see Contraindications (4) ] . 5.3 Clostridium difficile -Associated Diarrhea Published observational studies suggest that PPI therapy like esomeprazole magnesium delayed-release capsules may be associated with an increased risk of Clostridium difficile -associated diarrhea, especially in hospitalized patients. This diagnosis should be considered for diarrhea that does not improve [see Adverse Reactions (6.2) ] . Patients should use the lowest dose and shortest duration of PPI therapy appropriate to the condition being treated. Clostridium difficile -associated diarrhea (CDAD) has been reported with use of nearly all antibacterial agents. For more information specific to antibacterial agents (clarithromycin and amoxicillin) indicated for use in combination with esomeprazole magnesium delayed-release capsules, refer to Warnings and Precautions section of the corresponding prescribing information. 5.4 Bone Fracture Several published observational studies suggest that proton pump inhibitor (PPI) therapy may be associated with an increased risk for osteoporosis-related fractures of the hip, wrist, or spine. The risk of fracture was increased in patients who received high-dose, defined as multiple daily doses, and long-term PPI therapy (a year or longer). Patients should use the lowest dose and shortest duration of PPI therapy appropriate to the condition being treated. Patients at risk for osteoporosis-related fractures should be managed according to established treatment guidelines [see Dosage and Administration (2) and Adverse Reactions (6.2) ] . 5.5 Severe Cutaneous Adverse Reactions Severe cutaneous adverse reactions, including Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN), drug reaction with eosinophilia and systemic symptoms (DRESS), and acute generalized exanthematous pustulosis (AGEP) have been reported in association with the use of PPIs [see Adverse Reactions (6.2) ] . Discontinue esomeprazole magnesium delayed-release capsules at the first signs or symptoms of severe cutaneous adverse reactions or other signs of hypersensitivity and consider further evaluation. 5.6 Cutaneous and Systemic Lupus Erythematosus Cutaneous lupus erythematosus (CLE) and systemic lupus erythematosus (SLE) have been reported in patients taking PPIs, including esomeprazole. These events have occurred as both new onset and an exacerbation of existing autoimmune disease. The majority of PPI-induced lupus erythematosus cases were CLE. The most common form of CLE reported in patients treated with PPIs was subacute CLE (SCLE) and occurred within weeks to years after continuous drug therapy in patients ranging from infants to the elderly. Generally, histological findings were observed without organ involvement. Systemic lupus erythematosus (SLE) is less commonly reported than CLE in patients receiving PPIs. PPI associated SLE is usually milder than non-drug induced SLE. Onset of SLE typically occurred within days to years after initiating treatment primarily in patients ranging from young adults to the elderly. The majority of patients presented with rash; however, arthralgia and cytopenia were also reported. Avoid administration of PPIs for longer than medically indicated. If signs or symptoms consistent with CLE or SLE are noted in patients receiving esomeprazole magnesium delayed-release capsules, discontinue the drug and refer the patient to the appropriate specialist for evaluation. Most patients improve with discontinuation of the PPI alone in 4 to 12 weeks. Serological testing (e.g., ANA) may be positive and elevated serological test results may take longer to resolve than clinical manifestations. 5.7 Interaction with Clopidogrel Avoid concomitant use of esomeprazole magnesium delayed-release capsules with clopidogrel. Clopidogrel is a prodrug. Inhibition of platelet aggregation by clopidogrel is entirely due to an active metabolite. The metabolism of clopidogrel to its active metabolite can be impaired by use with concomitant medications, such as esomeprazole, that inhibit CYP2C19 activity. Concomitant use of clopidogrel with 40 mg esomeprazole reduces the pharmacological activity of clopidogrel. When using esomeprazole magnesium delayed-release capsules consider alternative anti-platelet therapy [see Drug Interactions (7) ] . 5.8 Cyanocobalamin (Vitamin B-12) Deficiency Daily treatment with any acid-suppressing medications over a long period of time (e.g., longer than 3 years) may lead to malabsorption of cyanocobalamin (vitamin B-12) caused by hypo- or achlorhydria. Rare reports of cyanocobalamin deficiency occurring with acid-suppressing therapy have been reported in the literature. This diagnosis should be considered if clinical symptoms consistent with…

Who should not take Esomeprazole Magnesium

Esomeprazole magnesium delayed-release capsules are contraindicated in patients with known hypersensitivity to substituted benzimidazoles or to any component of the formulation. Hypersensitivity reactions may include anaphylaxis, anaphylactic shock, angioedema, bronchospasm, acute tubulointerstitial nephritis, and urticaria [see Warnings and Precautions (5.2) , Adverse Reactions (6.2) ] . • For information about contraindications of amoxicillin and clarithromycin, indicated in combination with esomeprazole magnesium delayed-release capsules for H. pylori eradication to reduce the risk of duodenal ulcer recurrence, refer to the Contraindications section of the respective prescribing information. • Proton pump inhibitors (PPIs), including esomeprazole magnesium delayed-release capsules, are contraindicated in patients receiving rilpivirine-containing products [see Drug Interactions (7) ] . • Known hypersensitivity to substituted benzimidazoles or any component of the formulation. ( 4 ) • Patients receiving rilpivirine-containing products. ( 4 , 7 ) • Refer to the Contraindications section of the prescribing information for amoxicillin and clarithromycin, when administered in combination with esomeprazole magnesium delayed-release capsules. ( 4 )

Overdose — what happens if you take too much

Manifestations in patients exposed to omeprazole, the racemic mixture, at doses up to 2,400 mg (120 times the usual recommended clinical dose) include 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 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.

Interactions

Tables 3 and 4 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 3: 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 magnesium delayed-release capsules is contraindicated [see Contraindications (4) ] . Atazanavir: See prescribing information for atazanavir for dosing information. Nelfinavir: Avoid concomitant use with esomeprazole magnesium delayed-release capsules. 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 (5.12) ] . Intervention: A temporary withdrawal of esomeprazole magnesium delayed-release capsules may be considered in some patients receiving high-dose methotrexate. 2C19 Substrates (e.g., clopidogrel, citalopram, cilostazol) 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 dose of clopidogrel. Intervention: Avoid concomitant use with esomeprazole magnesium delayed-release capsules. Consider use of alternative anti-platelet therapy [see Warnings and Precautions (5.7) ] . Citalopram Clinical Impact: Increased exposure of citalopram leading to an increased risk of QT prolongation [see Clinical Pharmacology (12.3) ] . Intervention: Limit the dose of citalopram to a maximum of 20 mg per day. See prescribing information for citalopram. Cilostazol Clinical Impact: Increased exposure of cilostazol and one of its active metabolites (3,4-dihydro-cilostazol) [see Clinical Pharmacology (12.3) ] . Intervention: Consider reducing the dose of cilostazol to 50 mg twice daily. See prescribing information for cilostazol. Digoxin Clinical Impact: Potential for increased exposure of digoxin [see Clinical Pharmacology (12.3) ] . Intervention: Monitor digoxin concentrations and adjust the dose, if needed, to maintain therapeutic drug concentrations. See prescribing information for digoxin. Combination Therapy with Clarithromycin and Amoxicillin Clinical Impact: Concomitant administration of clarithromycin with other drugs can lead to serious adverse reactions, including potentially fatal arrhythmias, and are contraindicated. Amoxicillin also has drug interactions. Intervention: See Contraindications , Warnings and Precautions in prescribing information for clarithromycin. See Drug Interactions in prescribing information for amoxicillin. Drugs Dependent on Gastric pH for Absorption (e.g., iron salts, erlotinib, dasatinib, nilotinib, mycophenolate mofetil, ketoconazole/itraconazole) Clinical Impact: Esomeprazole can reduce the absorption of other drugs due to its effect on reducing intragastric acidity. Intervention: Mycophenolate mofetil (MMF): Co-administration of omeprazole, of which esomeprazole is an enantiomer, in healthy subjects and in transplant patients receiving MMF has been reported to reduce the exposure to the active metabolite, mycophenolic acid (MPA), possibly due to a decrease in MMF solubility at an increased gastric pH. The clinical relevance of reduced MPA exposure on organ rejection has not been established in transplant patients receiving esomeprazole magnesium delayed-release capsules and MMF. Use esomeprazole magnesium delayed-release capsules with caution in transplant patients receiving MMF [see Clinical Pharmacology (12.3) ] . See the prescribing information for other drugs dependent on gastric pH for absorption. Tacrolimus Clinical Impact: Potentially increased exposure of tacrolimus, especially in transplant patients who are intermediate or poor metabolizers of CYP2C19. Intervention: Monitor tacrolimus whole blood concentrations and consider reducing the dose, if needed, to maintain therapeutic drug concentrations. See prescribing information for tacrolimus. Interactions with Investigations of Neuroendocrine Tumors Clinical Impact: Serum chromogranin A (CgA) levels increase secondary to PPI-induced decreases in gastric acidity. The increased CgA level may cause false positive results in diagnostic investigations for neuroendocrine tumors [see Warnings and Precautions (5.11) , Clinical Pharmacology (12.2) ] . Intervention: Discontinue esomeprazole magnesium delayed-release capsules at least 14 days before assessing CgA levels and consider repeating the test if initial CgA levels are high. If serial tests are performed (e.g., for monitoring), the same commercial laboratory should be used for testing, as reference ranges between tests may vary. Interaction with Secretin Stimulation Test Clinical Impact: Hyper-response in gastrin secretion in response to secretin stimulation test, falsely suggesting gastrinoma. Intervention: Discontinue esomeprazole magnesium delayed-release capsules 4 weeks prior to testing [see Clinical Pharmacology (12.2) ] . False Positive Urine Tests for THC Clinical Impact: There have been reports of false positive urine screening test for tetrahydrocannabinol (THC) in patients receiving PPIs. Intervention: An alternative confirmatory method should be considered to verify positive results. Table 4: Clinically Relevant Interactions Affecting Esomeprazole When Co-Administered with Other Drugs CYP2C19 or CYP3A4 Inducers Clinical Impact: Decreased exposure of esomeprazole when used concomitantly with strong inducers [see Clinical Pharmacology (12.3) ] . Intervention: St. John’s Wort, rifampin: Avoid concomitant use with esomeprazole magnesium delayed-release capsules [see Warnings and Precautions (5.10) ] . Ritonavir-containing products: see prescribing information for specific drugs. Voriconazole Clinical Impact: Increased exposure of esomeprazole [see Clinical Pharmacology (12.3) ] . Intervention: Dose adjustment of esomeprazole magnesium delayed-release capsules is not normally required. However, in patients with Zollinger-Ellison syndrome, who may require higher doses, dosage adjustment may be considered. See prescribing information for voriconazole. See full prescribing information for a list of clinically important drug interactions. ( 7 )
