About this medicine
The active ingredient in dexlansoprazole delayed-release capsules, a proton pump inhibitor, is (+)-2-[(R)-{[3-methyl-4-(2,2,2-trifluoroethoxy)pyridin-2-yl] methyl} sulfinyl]- 1H -benzimidazole, a compound that inhibits gastric acid secretion. Dexlansoprazole is the R -enantiomer of lansoprazole (a racemic mixture of the R -and S -enantiomers). Its empirical formula is: C 16 H 14 F 3 N 3 O 2 S, with a molecular weight of 369.36. Dexlansoprazole has the following chemical structure: Dexlansoprazole is a white to brownish powder which melts at about 146°C. Dexlansoprazole is freely soluble in methanol, dichloromethane, soluble in acetonitrile, practically insoluble in water. Dexlansoprazole is stable when exposed to light. Dexlansoprazole is more stable in neutral and alkaline conditions than acidic conditions. Dexlansoprazole is supplied for oral administration as a dual delayed-release formulation in capsules. The capsules contain dexlansoprazole in a mixture of two types of enteric-coated pellets with different pH-dependent dissolution profiles [see Clinical Pharmacology (12.3)]. Dexlansoprazole delayed-release capsules are available in two dosage strengths: 30 and 60 mg, per capsule. Each capsule contains enteric-coated pellets consisting of dexlansoprazole (active ingredient) and the following inactive ingredients: colloidal silicon dioxide, confectioner’s sugar, croscarmellose sodium, hydroxypropyl cellulose, hypromellose, magnesium carbonate, methacrylic acid copolymer dispersion, methacrylic acid and methyl methacrylate copolymer (1:1), methacrylic acid and methyl methacrylate copolymer (1:2), polyethylene glycol 8000, polysorbate 80, sodium lauryl sulfate, sugar spheres (composed of corn starch, sucrose, and water), talc, titanium dioxide and triethyl citrate. The capsule shell contains carrageenan, hypromellose and potassium chloride, Additionally, 30 mg capsule shell contains FD&C Blue No. 1, iron oxide red, iron oxide yellow, titanium dioxide and whereas 60 mg capsule shell contains iron oxide red. The capsule shells are printed with edible ink containing black iron oxide, potassium hydroxide and shellac. dexlansoprazole-str.jpg
How it works
12.1 Mechanism of Action Dexlansoprazole belongs to a class of antisecretory compounds, the substituted benzimidazoles, that suppress gastric acid secretion by specific inhibition of the (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, dexlansoprazole has been characterized as a gastric proton-pump inhibitor, in that it blocks the final step of acid production.
Who should not take it
• Dexlansoprazole delayed-release capsules are contraindicated in patients with known hypersensitivity to any component of the formulation [see Description (11)] . Hypersensitivity reactions may include anaphylaxis, anaphylactic shock, angioedema, bronchospasm, acute tubulointerstitial nephritis and urticaria [see Warnings and Precautions (5.2), Adverse Reactions (6)]. • PPIs, including dexlansoprazole delayed-release capsules, are contraindicated with rilpivirine-containing products [see Drug Interactions (7)]. • Patients with known hypersensitivity to any component of the formulation. ( 4 ) • Patients receiving rilpivirine-containing products. ( 4 , 7 )
Warnings and cautions
• Gastric Malignancy: In adults, symptomatic response with dexlansoprazole 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 dexlansoprazole and refer to specialist for evaluation. ( 5.6 ) • Cyanocobalamin (Vitamin B12) Deficiency: Daily long-term use (e.g., longer than 3 years) may lead to malabsorption or a deficiency of cyanocobalamin. ( 5.7 ) • Hypomagnesemia and Mineral Metabolism: Reported rarely with prolonged treatment with PPIs. ( 5.8 ) • Interactions with Investigations for Neuroendocrine Tumors: Increases in intragastric pH may result in hypergastrinemia and enterochromaffin-like cell hyperplasia and increased chromogranin A levels which may interfere with diagnostic investigations for neuroendocrine tumors. ( 5.9 , 7 ) • 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 a temporary withdrawal of dexlansoprazole. ( 5.10 , 7 ) • Fundic Gland Polyps: Risk increases with long-term use, especially beyond 1 year. Use the shortest duration of therapy. ( 5.11 ) • Risk of Heart Valve Thickening in Pediatric Patients Less than Two Years of Age: Dexlansoprazole is not recommended in pediatric patients less than 2 years of age. […]

The following serious adverse reactions are described below and elsewhere in labeling: • Acute Tubulointerstitial Nephritis [see Warnings and Precautions (5.2)] • Clostridium difficile -Associated Diarrhea [see Warnings and Precautions (5.3)] • Bone Fracture [see Warnings and Precautions (5.4)] • Severe Cutaneous Adverse Reactions [see Warnings and Precautions (5.5)] • Cutaneous and Systemic Lupus Erythematosus [see Warnings and Precautions (5.6)] • Cyanocobalamin (Vitamin B12) Deficiency [see Warnings and Precautions (5.7)] • Hypomagnesemia and Mineral Metabolism [see Warnings and Precautions (5.8)] • Fundic Gland Polyps [see Warnings and Precautions (5.11)] • Risk of Heart Valve Thickening in Pediatric Patients Less than Two Years of Age [see Warnings and Precautions (5.12)] The most common adverse reactions are: • Adults (≥2%): diarrhea, abdominal pain, nausea, upper respiratory tract infection, vomiting, and flatulence. ( 6.1 ) • Patients 12 to 17 years of age (≥5%): headache, abdominal pain, diarrhea, nasopharyngitis, and oropharyngeal pain. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact 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. Adults The safety of dexlansoprazole was evaluated in 4548 adult patients in controlled and single-arm clinical trials, including 863 patients treated for at least six months and 203 patients treated for one year. Patients ranged in age from 18 to 90 years (median age 48 years), with 54% female, 85% Caucasian, 8% Black, 4% Asian, and 3% Other races. Six randomized controlled clinical trials were conducted for the treatment of EE, maintenance of healed EE, and symptomatic GERD, which included 896 patients on placebo, 455 patients on dexlansoprazole 30 mg, 2218 patients on dexlansoprazole 60 mg, and 1363 patients on lansoprazole 30 mg once daily.

Interactions with other medicines
Tables 3 and 4 include drugs with clinically important drug interactions and interaction with diagnostics when administered concomitantly with dexlansoprazole 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 Coadministered with Dexlansoprazole and Interactions 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 dexlansoprazole may reduce antiviral effect and promote the development of drug resistance . Increased exposure of other antiretroviral drugs (e.g., saquinavir) when used concomitantly with dexlansoprazole may increase toxicity of the antiretroviral drugs. There are other antiretroviral drugs which do not result in clinically relevant interactions with dexlansoprazole. Intervention: Rilpivirine-containing products : Concomitant use with dexlansoprazole is contraindicated [see Contraindications (4)] . See prescribing information. Atazanavir : See prescribing information for atazanavir for dosing information. Nelfinavir : Avoid concomitant use with dexlansoprazole. See prescribing information for nelfinavir. Saquinavir : See the prescribing information for saquinavir and monitor for potential saquinavir toxicities. Other antiretrovirals : See prescribing information. Warfarin Clinical Impact: Increased INR and prothrombin time in patients receiving PPIs and warfarin concomitantly. Increases in INR and prothrombin time may lead to abnormal bleeding and even death. Intervention: Monitor INR and prothrombin time. Dose adjustment of warfarin may be needed to maintain target INR range. See prescribing information for warfarin. […]
Use in specific groups
• Pregnancy : Based on animal data, may cause adverse effects on fetal bone growth and development. ( 8.1 ) • Pediatrics : Based on data with lansoprazole, dexlansoprazole is not effective in patients with symptomatic GERD 1 month to less than 1 year of age and nonclinical studies have demonstrated adverse effects in juvenile rats. ( 8.4 ) 8.1 Pregnancy Risk Summary There are no studies with dexlansoprazole use in pregnant women to inform a drug-associated risk. Dexlansoprazole is the R-enantiomer of lansoprazole, and published observational studies of lansoprazole use during pregnancy did not demonstrate an association of adverse pregnancy-related outcomes with lansoprazole ( see Data ). In animal reproduction studies, oral administration of lansoprazole to rats during organogenesis through lactation at 1.8 times the maximum recommended human dexlansoprazole dose produced reductions in the offspring in femur weight, femur length, crown-rump length and growth plate thickness (males only) on postnatal Day 21 ( see Data ). These effects were associated with reduction in body weight gain. Advise pregnant women of the potential risk to the fetus. The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the US 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 Dexlansoprazole is the R-enantiomer of lansoprazole. Available data from published observational studies failed to demonstrate an association of adverse pregnancy-related outcomes and lansoprazole use. Methodological limitations of these observational studies cannot definitely establish or exclude any drug-associated risk during pregnancy. In a prospective study by the European Network of Teratology Information Services, outcomes from a group of 62 pregnant women administered median daily doses of 30 mg of lansoprazole were compared to a control group of 868 pregnant women who did not take any PPIs.

If too much is taken
There have been no reports of significant overdose with dexlansoprazole. Multiple doses of dexlansoprazole 120 mg and a single dose of dexlansoprazole 300 mg did not result in death or other severe adverse events. However, serious adverse events of hypertension have been reported in association with twice daily doses of dexlansoprazole 60 mg. Nonserious adverse reactions observed with twice daily doses of dexlansoprazole 60 mg include hot flashes, contusion, oropharyngeal pain, and weight loss. Dexlansoprazole is not expected to be removed from the circulation by hemodialysis. In the event of over-exposure, 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 over-exposure.
