Dosing: Adult

Eosinophilic esophagitis (off-label use): Oral: 30 mg twice daily for an 8-week trial (Bonis 2021; Laserna-Mendieta 2020; Lucendo 2016; Vazquez-Elizondo 2013). Once 8-week trial is complete and remission is achieved, the dose may be gradually lowered to an individualized maintenance level (Laserna-Mendieta 2020). Some experts initiate with once-daily dosing and increase to twice-daily dosing after 4 weeks if symptoms fail to improve (Bonis 2021).

Gastroesophageal reflux disease (GERD), treatment: Note: Administer 30 to 60 minutes before a meal (breakfast is preferred). Lifestyle and dietary modifications are also recommended (ACG [Katz 2013]).

Initial therapy:

Mild and intermittent symptoms (<2 episodes/week), and no evidence of erosive esophagitis: Note: Some experts consider PPI use in these patients only if symptoms persist following standard-doses of histamine 2 receptor antagonists (Kahrilas 2019). Oral: 15 mg once daily for 8 weeks; if symptoms persist after 8 weeks, increase to 30 mg once daily; once symptoms are controlled, continue treatment for at least 8 weeks. Discontinue therapy when asymptomatic for 8 weeks with therapy (consider tapering before discontinuing) (Kahrilas 2019).

Severe or frequent symptoms (≥2 episodes/week), erosive esophagitis, or Barrett esophagus: Oral: 30 mg once daily; once symptoms are controlled, continue treatment for at least 8 weeks. In patients with severe erosive esophagitis or Barrett esophagus, long-term maintenance therapy with 30 mg once daily is warranted. In patients without severe erosive esophagitis or Barrett esophagus, continue at the lowest dose for the shortest duration appropriate, discontinue therapy in all asymptomatic patients (consider tapering before discontinuing) (Kahrilas 2019; Ramakrishnan 2002).

Refractory:

Persistent symptoms despite 30 mg once daily dosing regimen: Note: Referral to a specialist is recommended: Oral: 30 mg twice daily (before breakfast and dinner) (ACG [Katz 2013]; Fass 2019; Hershcovici 2010) or some experts consider splitting the 30 mg once daily dose and administering 15 mg twice daily before breakfast and dinner (Fass 2019).

Recurrent symptoms after discontinuing acid suppression:

Recurrent symptoms ≥3 months: Repeat an 8-week course at the previously effective dose (Kahrilas 2019).

Recurrent symptoms <3 months: Long-term maintenance at the lowest effective dose necessary; upper endoscopy is also recommended (if not already performed) (ACG [Katz 2013]; Kahrilas 2019).

OTC labeling (patient-guided therapy): Heartburn, frequent symptoms (≥2 episodes/week): 15 mg once daily for 14 days (maximum: 15 mg/day); may repeat a 14-day course every 4 months, if needed.

Hypersecretory conditions: Oral: Initial: 60 mg once daily; adjust dose based upon patient response and to reduce acid secretion to <10 mEq/hour (5 mEq/hour in patients with prior gastric surgery); doses of 90 mg twice daily have been used; administer doses >120 mg/day in divided doses

Peptic ulcer disease:

Duodenal ulcer: Oral: Short-term treatment: 15 mg once daily for 4 weeks; maintenance therapy: 15 mg once daily

Dyspepsia (off label use): Oral: 15 or 30 mg once daily for up to 8 weeks (Peura 2004; Pinto-Sanchez 2017; Suzuki 2013)

Gastric ulcer: Oral: Short-term treatment: 30 mg once daily for up to 8 weeks. Some clinical trial data suggests a dose of 15 mg once daily for up to 8 weeks may also be effective.

Helicobacter pylori eradication: Oral: 30 mg 3 times daily administered with amoxicillin 1,000 mg 3 times daily for 14 days or 30 mg twice daily administered with amoxicillin 1,000 mg and clarithromycin 500 mg twice daily for 10 to 14 days

American College of Gastroenterology guidelines (Chey 2007; Chey 2017):

Clarithromycin triple regimen: 30 to 60 mg twice daily in combination with clarithromycin 500 mg twice daily and either amoxicillin 1 g twice daily or metronidazole 500 mg 3 times per day for 14 days. Note: Avoid use of clarithromycin triple therapy in patients with risk factors for macrolide resistance (eg, prior macrolide exposure, local clarithromycin resistance rates ≥15%, eradication rates with clarithromycin-based regimens ≤85%) (ACG [Chey 2017]; Fallone 2016).

Sequential regimen: 30 mg twice daily plus amoxicillin 1 g twice daily for 5 to 7 days; then follow with clarithromycin 500 mg twice daily, either metronidazole or tinidazole 500 mg twice daily, and lansoprazole 30 mg twice daily for 5 to 7 days

Levofloxacin triple regimen: 30 mg twice daily in combination with amoxicillin 1 g twice daily and levofloxacin 500 mg once daily for 10 to 14 days

Bismuth quadruple regimen: 30 mg twice daily in combination with tetracycline 500 mg 4 times daily, metronidazole 250 mg 4 times daily or 500 mg 3 or 4 times daily, and either bismuth subcitrate 120 to 300 mg 4 times daily or bismuth subsalicylate 300 mg 4 times daily for 10 to 14 days

Concomitant regimen: 30 mg twice daily in combination with amoxicillin 1 g twice daily, clarithromycin 500 mg twice daily, and either metronidazole or tinidazole 500 mg twice daily for 10 to 14 days

Hybrid regimen: 30 mg twice daily plus amoxicillin 1 g twice daily for 7 days; then follow with amoxicillin 1 g twice daily, clarithromycin 500 mg twice daily, either metronidazole or tinidazole 500 mg twice daily, and lansoprazole 30 mg twice daily for 7 days

NSAID-associated gastric ulcer (healing): Oral: 30 mg once daily for 8 weeks; controlled studies did not extend past 8 weeks

NSAID-associated gastric ulcer (to reduce risk): Oral: 15 mg once daily for up to 12 weeks; controlled studies did not extend past 12 weeks

Stress ulcer prophylaxis in critically-ill patients (off-label use): Oral: 30 mg once daily (Brophy 2010; Olsen 2008). Note: Intended for patients with associated risk factors (eg, coagulopathy, mechanical ventilation for >48 hours, sepsis/septic shock); discontinue use once risk factors have resolved (Rhodes 2017).

Discontinuation of therapy: Oral: Some experts recommend a step-down approach in order to avoid worsening or rebound symptoms. One strategy is to decrease the dose by 50% over 2 to 4 weeks. If the patient is already on the lowest possible dose, alternate-day therapy may be considered. If symptoms worsen during treatment or after discontinuation, patient should be re-evaluated (Kim 2018).

Dosage adjustment for concomitant therapy: Significant drug interactions exist, requiring dose/frequency adjustment or avoidance. Consult drug interactions database for more information.

Dosing: Kidney Impairment: Adult

No dosage adjustment necessary.

Dosing: Hepatic Impairment: Adult

Mild or moderate impairment (Child-Pugh class A or B): No dosage adjustment necessary.

Severe impairment (Child-Pugh class C): 15 mg once daily. Note: Dosage recommendation is based on pharmacokinetic data using a single 30 mg dose.

Dosing: Pediatric

(For additional information see "Lansoprazole: Pediatric drug information")

Gastroesophageal reflux disease (GERD), symptomatic: Note: Guidelines recommend a 4- to 8-week treatment course; if improvement seen after 4 to 8 weeks, consider possible wean; if no response after 4 to 8 weeks, reevaluate diagnosis and consider referral to pediatric GI specialist (NASPGHAN/ESPGHAN [Rosen 2018]). The manufacturer recommends not using lansoprazole in infants due to lack of clinical efficacy data and the potential for adverse effects (ie, heart valve thickening) observed in animal models (rats).

Weight-based dosing:

Infants: Oral: 2 mg/kg/day (NASPGHAN/ESPGHAN [Rosen 2018]); a dose of 1 mg/kg/day has also been shown to increase gastric pH in infants and decrease frequency of GERD symptoms (eg, regurgitation/vomiting, feeding refusal, crying, back arching) from baseline (Springer 2008).

Children and Adolescents: Oral: 0.7 to 3 mg/kg/day (AAP [Lightdale 2013]); maximum daily dose: 30 mg/day (NASPGHAN/ESPGHAN [Rosen 2018]).

Fixed dosing:

Infants ≥3 months: 7.5 mg twice daily or 15 mg once daily was shown to provide better symptom relief compared to dietary management in 68 patients (Khoshoo 2008).

Children ≤11 years:

≤30 kg: 15 mg once daily.

>30 kg: 30 mg once daily.

Children ≥12 years and Adolescents: Oral: 15 mg once daily.

Erosive esophagitis, treatment: Note: Duration of therapy is dependent on age: Children ≤11 years recommended duration is up to 12 weeks and children ≥12 years and adolescent duration is up to 8 weeks.

Children ≤11 years:

≤30 kg: 15 mg once daily.

>30 kg: 30 mg once daily.

Children ≥12 years and Adolescents: Oral: 30 mg once daily.

Discontinuation of therapy: Oral: Based on experience in adults, some experts recommend a step-down approach in order to avoid worsening or rebound symptoms. One recommendation is to decrease the dose by 50% over 2 to 4 weeks. If the patient is already on the lowest possible dose, alternate day therapy may be considered. If symptoms worsen during treatment or after discontinuation, patient should be reevaluated (Kim 2018).

Dosage adjustment for concomitant therapy: Significant drug interactions exist, requiring dose/frequency adjustment or avoidance. Consult drug interactions database for more information.

Dosing: Kidney Impairment: Pediatric

Children and Adolescents: No dosage adjustments are needed.

Dosing: Hepatic Impairment: Pediatric

Children and Adolescents: Drug exposure is increased in hepatic impairment; consider dose reduction for severe impairment

Medication Guide and/or Vaccine Information Statement (VIS)

An FDA-approved patient medication guide, which is available with the product information and as follows, must be dispensed with this medication:

Prevacid capsules, orally disintegrating tablets: https://www.accessdata.fda.gov/drugsatfda_docs/label/2020/020406s092,021428s039lbl.pdf#page=44

Administration: Adult

Oral: Administer 30 to 60 minutes before a meal; best if taken before breakfast (ACG [Katz 2013]). If administering twice daily, first dose should be administered before breakfast and the second dose before dinner (ACG [Katz 2013]; Hershcovici 2010). The intact granules should not be chewed or crushed; however, several options are available for those patients unable to swallow capsules:

Capsules may be opened and the intact granules sprinkled on 1 tablespoon of applesauce, Ensure pudding, cottage cheese, yogurt, or strained pears. The granules should then be swallowed immediately.

Capsules may be opened and emptied into ~60 mL orange juice, apple juice, or tomato juice; mix and swallow immediately. Rinse the glass with 2 or more volumes of juice and swallow immediately to assure complete delivery of the dose.

Orally disintegrating tablets: Should not be swallowed whole, broken, cut, or chewed. Place tablet on tongue; allow to dissolve (with or without water) until particles can be swallowed. Orally-disintegrating tablets may also be administered via an oral syringe: Place the 15 mg tablet in an oral syringe and draw up ~4 mL water, or place the 30 mg tablet in an oral syringe and draw up ~10 mL water. After tablet has dispersed, administer within 15 minutes. Refill the syringe with water (2 mL for the 15 mg tablet; 5 mL for the 30 mg tablet), shake gently, then administer any remaining contents.

Nasogastric tube administration:

Capsule: Capsule can be opened, the granules mixed (not crushed) with 40 mL of apple juice and then administered through the NG tube into the stomach, then flush tube with additional apple juice. Do not mix with other liquids. Thirty milligrams has also been suspended in 10 mL of 8.4% sodium bicarbonate solution (or apple juice) or divided into 4 equal parts and flushed with water and administered via NG tube (Brophy 2010; Tsai 2000).

Orally disintegrating tablet: Nasogastric tube ≥8 French: Place a 15 mg tablet in a syringe and draw up ~4 mL water, or place the 30 mg tablet in a syringe and draw up ~10 mL water. After tablet has dispersed, administer within 15 minutes (gently shake syringe immediately prior to administration). Refill the syringe with ~5 mL water, shake gently, and then flush the nasogastric tube.

Administration: Pediatric

Oral: Administer before eating; best if taken 30 minutes before a meal (AAP [Lightdale 2013]); intact granules should not be chewed or crushed

Capsules: Swallow whole; do not chew or crush. For patients with difficulty swallowing the capsule, capsules may be opened and the intact granules sprinkled on 1 tablespoon of applesauce, Ensure pudding, cottage cheese, yogurt, or strained pears; the mixture should be swallowed immediately. Capsules may also be opened and emptied into ~60 mL of apple juice, orange juice, or tomato juice; mix and swallow immediately. Rinse the glass with additional juice and swallow to assure complete delivery of the dose.

For nasogastric tube ≥16 French: Capsule can be opened, the granules mixed (not crushed) with 40 mL of apple juice and then injected through the NG tube into the stomach, then flush tube with additional apple juice. Do not mix with other liquids based on manufacturer labeling; additional information may be available for NG administration; contact manufacturer to obtain current recommendations.

Tablet, orally-disintegrating: Should not be swallowed whole, broken, cut, or chewed. Splitting of orally-disintegrating tablets may result in significant differences in amount of lansoprazole containing microgranules in each half, clinical relevance of this difference is not well-described (Teitelbaum 2015). Place the tablet on the tongue and allow to disintegrate with or without water until the particles can be swallowed.

Administration via an oral syringe: Place the 15 mg tablet in an oral syringe and draw up ~4 mL water, or place the 30 mg tablet in an oral syringe and draw up ~10 mL water. Shake gently. After tablet has dispersed, administer within 15 minutes. Refill the syringe with water (2 mL for the 15 mg tablet; 5 mL for the 30 mg tablet), shake gently, then administer any remaining contents.

For nasogastric tube ≥8 French: Place a 15 mg tablet in a syringe and draw up ~4 mL water, or place the 30 mg tablet in a syringe and draw up ~10 mL water. Shake gently. After tablet has dispersed, administer within 15 minutes. Refill the syringe with ~5 mL water, shake gently, and then flush the nasogastric tube.

Warnings/Precautions

Concerns related to adverse effects:

• Carcinoma: No reports of enterochromaffin-like (ECL) cell carcinoids, dysplasia, or neoplasia has occurred.

Clostridioides difficile-associated diarrhea (CDAD): Use of proton pump inhibitors (PPIs) may increase risk of CDAD, especially in hospitalized patients; consider CDAD diagnosis in patients with persistent diarrhea that does not improve. Use the lowest dose and shortest duration of PPI therapy appropriate for the condition being treated.

• Cutaneous and systemic lupus erythematosus: Has been reported as new onset or exacerbation of existing autoimmune disease; most cases were cutaneous lupus erythematosus (CLE), most commonly, subacute CLE (occurring within weeks to years after continuous therapy). Systemic lupus erythematosus (SLE) is less common (typically occurs within days to years after initiating treatment) and occurred primarily in young adults up to elderly patients. Discontinue therapy if signs or symptoms of CLE or SLE occur and refer to a specialist for evaluation; most patients improve 4 to 12 weeks after discontinuation of lansoprazole.

• Fractures: Increased incidence of osteoporosis-related bone fractures of the hip, spine, or wrist may occur with PPI therapy. Patients on high-dose or long-term therapy should be monitored. Use the lowest effective dose for the shortest duration of time, use vitamin D and calcium supplementation, and follow appropriate guidelines to reduce risk of fractures in patients at risk.

• Fundic gland polyps: Use of PPIs increases risk of fundic gland polyps, especially with long-term use >1 year. May occur without symptoms, but nausea, vomiting, or abdominal pain may occur; GI bleeding and/or anemia may occur with ulcerated polyps. Diagnosis of polyps may also increase risk for small intestinal blockage. Use the lowest dose and shortest duration of PPI therapy appropriate for the condition being treated.

• Hypomagnesemia: Reported rarely, usually with prolonged PPI use of ≥3 months (most cases >1 year of therapy). May be symptomatic or asymptomatic; severe cases may cause tetany, seizures, and cardiac arrhythmias. Consider obtaining serum magnesium concentrations prior to beginning long-term therapy, especially if taking concomitant digoxin, diuretics, or other drugs known to cause hypomagnesemia; and periodically thereafter. Hypomagnesemia may be corrected by magnesium supplementation, although discontinuation of lansoprazole may be necessary; magnesium levels typically return to normal within 1 week of stopping.

• Tubulointerstitial nephritis: Acute tubulointerstitial nephritis has been observed in patients taking PPIs; may occur at any time during therapy. Patients may present with symptomatic hypersensitivity reaction to nonspecific symptoms of impaired renal function (eg, anorexia, malaise, nausea); may be diagnosed with biopsy and in the absence of extra-renal manifestations (eg, fever, rash, arthralgia). Discontinue and evaluate patients if acute tubulointerstitial nephritis is suspected.

• Vitamin B12 deficiency: Prolonged treatment (≥2 years) may lead to vitamin B12 malabsorption and subsequent vitamin B12 deficiency. The magnitude of the deficiency is dose-related and the association is stronger in females and those younger in age (<30 years of age); prevalence is decreased after discontinuation of therapy (Lam 2013).

Disease-related concerns:

• Gastric malignancy: Relief of symptoms does not preclude the presence of a gastric malignancy.

• Gastrointestinal infection (eg, Salmonella, Campylobacter): Use of PPIs may increase risk of these infections.

• Hepatic impairment: Patients with severe liver dysfunction may require dosage reductions.

Concurrent drug therapy issues:

• Clopidogrel: PPIs may diminish the therapeutic effect of clopidogrel thought to be due to reduced formation of the active metabolite of clopidogrel. The manufacturer of clopidogrel recommends either avoidance of both omeprazole (even when scheduled 12 hours apart) and esomeprazole or use of a PPI with comparatively less effect on the active metabolite of clopidogrel (eg, pantoprazole). Although lansoprazole exhibits the most potent CYP2C19 inhibition in vitro (Li 2004; Ogilvie 2011), an in vivo study of extensive CYP2C19 metabolizers showed less reduction of the active metabolite of clopidogrel by lansoprazole/dexlansoprazole compared to esomeprazole/omeprazole (Frelinger 2012). The manufacturer of lansoprazole states that no dosage adjustment is necessary for clopidogrel when used concurrently. In contrast to these warnings, others have recommended the continued use of PPIs, regardless of the degree of inhibition, in patients with a history of GI bleeding or multiple risk factors for GI bleeding who are also receiving clopidogrel since no evidence has established clinically meaningful differences in outcome; however, a clinically significant interaction cannot be excluded in those who are poor metabolizers of clopidogrel (Abraham 2010; Levine 2011).

Dosage form specific issues:

• Benzyl alcohol and derivatives: Some dosage forms may contain benzyl alcohol; large amounts of benzyl alcohol (≥99 mg/kg/day) have been associated with a potentially fatal toxicity (“gasping syndrome”) in neonates; the “gasping syndrome” consists of metabolic acidosis, respiratory distress, gasping respirations, CNS dysfunction (including convulsions, intracranial hemorrhage), hypotension, and cardiovascular collapse (AAP ["Inactive" 1997]; CDC 1982); some data suggests that benzoate displaces bilirubin from protein binding sites (Ahlfors 2001); avoid or use dosage forms containing benzyl alcohol with caution in neonates. See manufacturer's labeling.

• Phenylalanine: Some products may contain phenylalanine, which can be harmful to patients with phenylketonuria (PKU). Before prescribing, consider the combined daily amount of phenylalanine from all sources.

Other warnings/precautions:

• Appropriate use: Helicobacter pylori eradication: Short-term combination therapy (≤7 days) has been associated with a higher incidence of treatment failure. The American College of Gastroenterology recommends 10 to 14 days of therapy (triple or quadruple) for eradication of H. pylori (Chey 2017).

• Laboratory test interference: Serum chromogranin A (CgA) levels increase secondary to drug-induced decreases in gastric acid; may cause false-positive results in diagnostic investigations for neuroendocrine tumors. Temporarily stop lansoprazole treatment at least 14 days before CgA test; if CgA level is high, repeat test to confirm. Use same commercial laboratory for testing to prevent variable results.

• Self-medication (OTC use): When used for self-medication, patients should be instructed not to use if they have difficulty swallowing, are vomiting blood, or have bloody or black stools. Prior to use, patients should contact healthcare provider if they have liver disease, heartburn for >3 months, heartburn with dizziness, lightheadedness, or sweating, MI symptoms, frequent chest pain, frequent wheezing (especially with heartburn), unexplained weight loss, nausea/vomiting, stomach pain, or are taking antifungals, atazanavir, digoxin, tacrolimus, theophylline, or warfarin. Patients should stop use and consult a healthcare provider if heartburn continues or worsens, or if they need to take for >14 days or more often than every 4 months. Patients should be informed that it may take 1 to 4 days for full effect to be seen.

Warnings: Additional Pediatric Considerations

Use in neonatal and pediatric patients <12 months of age is not recommended in the product labeling; neonatal and infant animal models (rat) have shown mitral valve heart thickening in 2 nonclinical, oral toxicity studies. Heart valve thickening occurred at doses 6.2 times (neonates) and 4.2 times (infants) the pediatric daily dose of 15 mg; duration of treatment associated with valve thickening ranged from 5 days to 8 weeks. Valve thickening reversed or trended towards reversibility 4 weeks after discontinuation. The risk of heart valve thickening does not appear to occur at ≥1 year of age. Evaluate risk vs benefit when considering use in neonates and infants.

Use of gastric acid inhibitors, including proton pump inhibitors (PPIs) and H2 blockers, has been associated with an increased risk for development of acute gastroenteritis and community-acquired pneumonia in pediatric patients 4 to 36 months of age (Canani 2006). Routine use in preterm infants is not recommended (AAP [Eichenwald 2018]).

Gastric acid suppression medications have been associated with an increase in Clostridioides difficile infection (CDI) and recurrent CDI in pediatric patients (Nylund 2014). In a retrospective, observational, case control study of pediatric patients 1 to 18 years old who were hospitalized for diarrhea and abdominal pain, the use of PPIs was significantly higher in patients who tested positive for C. difficile compared to patients who tested negative for C. difficile (22.1% vs 5.9%) (Turco 2010). Consider CDI diagnosis in patients with persistent diarrhea that does not improve. Use the lowest dose and shortest duration of PPI therapy appropriate for the condition being treated.

A large retrospective cohort study reviewed records for patients with a low baseline risk for fractures who were initiated on acid suppression therapy in the first year of life and evaluated the fracture risk in the first 5 years of life; a total of 97,286 patients were prescribed acid suppression therapy; 73% were prescribed H2 blockers, 9% were prescribed PPIs, and 18% were prescribed both. H2 blocker use alone was not associated with an increased fracture hazard; however, PPI use was associated with a 21% increase and use of PPI plus H2 blocker was associated with a 30% increase. Longer duration of therapy and earlier age at initiation seemed to also increase the fracture hazard. Study findings do not establish a causal relationship between PPI use and fractures. If acid suppression therapy is necessary in the first year of life, limiting therapy to a single drug and limiting the duration should be considered (Malchodi 2019). A second large cohort study reviewed records for 115,933 children <18 years initiated on a PPI. PPI initiation was associated with a statistically significant 11% relative increase in risk of any fracture in patients ≥6 years. The increased risk also seemed to be more pronounced with a longer cumulative duration of PPI use (Wang 2020).

Food Interactions

Prolonged treatment (≥2 years) may lead to malabsorption of dietary vitamin B12 and subsequent vitamin B12 deficiency (Lam 2013).

Pregnancy Considerations

Available data have not shown an increased risk of major birth defects following maternal use of lansoprazole during pregnancy.

Recommendations for the treatment of GERD in pregnancy are available. As in nonpregnant patients, lifestyle modifications followed by other medications are the initial treatments (ACG [Katz 2013]; Body 2016; Huerta-Iga 2016; van der Woude 2014). Based on available data, proton pump inhibitors may be used when clinically indicated (Body 2016; Matok 2012; Pasternak 2010; van der Woude 2014).

Breastfeeding Considerations

It is not known if lansoprazole is present in breast milk.

According to the manufacturer, the decision to breastfeed during therapy should consider the risk of infant exposure, the benefits of breastfeeding to the infant, and benefits of treatment to the mother.

Dietary Considerations

Should be taken before eating; best if taken before breakfast. Some products may contain phenylalanine.

Monitoring Parameters

Patients with Zollinger-Ellison syndrome should be monitored for gastric acid output, which should be maintained at ≤10 mEq/hour during the last hour before the next lansoprazole dose; bone loss and fractures, CBC, CDAD, liver function, renal function, magnesium (baseline and periodically thereafter), and serum gastrin levels

Mechanism of Action

Decreases acid secretion in gastric parietal cells through inhibition of (H+, K+)-ATPase enzyme system, blocking the final step in gastric acid production.

Pharmacokinetics

Onset of action: Gastric acid suppression: Oral: 1 to 3 hours

Duration: Gastric acid suppression: Oral: >1 day

Absorption: Rapid

Distribution: Vd: Children: 0.61 to 0.9 L/kg; Adults: 15.7 ± 1.9 L

Protein binding: 97%

Metabolism: Hepatic via CYP2C19 and 3A4 to inactive metabolites, and in parietal cells to two active metabolites that are not present in systemic circulation

Bioavailability: >80%; decreased 50% to 70% if given 30 minutes after food

Half-life elimination: Children: 1.2 to 1.5 hours; Adults: 1.5 ± 1 hour; Elderly: 1.9 to 2.9 hours; Hepatic impairment: 4 to 7.2 hours

Time to peak, plasma: 1.7 hours

Excretion: Feces (67%); urine (33%; 14% to 25% as metabolites and <1% as unchanged drug)

Clearance:

Children: 0.57 to 0.71 L/hour/kg

Adults: 11.1 ± 3.8 L/hour; Hepatic impairment: 3.2 to 7.2 hours

Pharmacokinetics: Additional Considerations

Hepatic function impairment: In patients with mild (Child-Pugh class A) or moderate (Child-Pugh class B) hepatic impairment, AUC increased ~3-fold and half-life increased from 1.5 hours to 4 or 5 hours, respectively. In patients with compensated and decompensated cirrhosis, AUC increased 6- and 5-fold, respectively.

Geriatric: Clearance is decreased with t½ increasing ~50% to 100%. Because mean t½ remains between 1.9 to 2.9 hours, repeated once daily dosing does not accumulate.
