Off Label Uses
Aspiration prophylaxis in patients undergoing anesthesia
Data from several studies of varying methodologies (including randomized, single-blind and double-blind, parallel-group trials) and a meta-analysis support the use of pantoprazole for the prevention of aspiration in patients undergoing anesthesia. Studies were conducted in the elective surgery setting [Bhattacharyya 2011], [Memis 2003], [Pisegna 2009], [Puig 2012].
Based on the American Society of Anesthesiologists practice guidelines for preoperative fasting and the use of pharmacologic agents to reduce the risk of pulmonary aspiration, proton pump inhibitors (PPIs) (eg, pantoprazole) are an effective and recommended option for use in patients at high risk for aspiration.
Data from an observational study suggest that use of a PPI, such as pantoprazole, may prevent cancer and the progression of dysplasia in patients with this condition [Kastelein 2013], although evidence is conflicting [Hu 2017]. Clinical experience also suggests the utility of PPIs in the treatment of patients with Barrett esophagus and symptomatic gastroesophageal reflux disease (GERD) or endoscopic evidence of reflux esophagitis [Spechler 2020].
Based on the American College of Gastroenterology (ACG) clinical guideline for diagnosis and management of Barrett esophagus, PPIs (eg, pantoprazole) are effective and recommended in patients with this condition [Shaheen 2016].
Dyspepsia, functional (idiopathic or non-ulcer)
Data from a multicenter, double-blind, placebo-controlled trial as well as from a double-blind noninferiority trial support the use of pantoprazole for the treatment of functional dyspepsia [Jung 2016], [van Rensburg 2008]. In addition, data from a systematic review support the use of pantoprazole for the treatment of patients with ulcer and reflux-like functional dyspepsia [Pinto-Sanchez 2017].
Based on the ACG and Canadian Association of Gastroenterology (CAG) guidelines for the management of dyspepsia, the use of pantoprazole is effective and recommended treatment for functional dyspepsia [ACG/CAG [Moayyedi 2017]].
Helicobacter pylori eradication
Based on the ACG clinical guideline for treatment of H. pylori infection, the use of PPIs, as part of an appropriate combination regimen with antibiotics, is effective and recommended in the treatment of H. pylori infection [ACG [Chey 2017]].
Nonsteroidal anti-inflammatory drug (including aspirin)–induced ulcers, primary prevention
Data from a randomized, double-blind, multicenter, parallel-group study and from a limited number of patients in a placebo-controlled, double-blind, parallel-group study support the use of pantoprazole in the prevention of nonsteroidal anti-inflammatory drug (NSAID)–induced ulcers [Bianchi Porro 2000], [Regula 2006].
Based on the ACG 2009 guidelines for prevention of NSAID-related ulcer complications, PPIs (including pantoprazole) are effective and recommended in the prophylaxis of gastric and duodenal ulcers in patients receiving NSAID therapy [Lanza 2009]. In addition, based on the European Society of Cardiology (ESC) guidelines for the management of acute myocardial infarction in patients presenting with ST-segment elevation and the American College of Cardiology Foundation/ACG/American Heart Association expert consensus document on the concomitant use of PPIs and thienopyridines, PPIs are effective and recommended for gastric protection in patients on dual antiplatelet therapy (eg, aspirin plus a P2Y12 inhibitor) who are at high risk for GI bleeding, such as those with a history of GI ulcer/bleeding or with multiple additional risk factors (eg, H. pylori infection, concurrent use of anticoagulants or corticosteroids) [Abraham 2010], [Ibanez 2018].
Peptic ulcer disease, maintenance therapy/secondary prevention
Data from a randomized, double-blind trial and a parallel, randomized, placebo-controlled noninferiority trial support the use of pantoprazole for secondary prevention of ulcers and/or GI bleeding in select high-risk patients with a need for continued aspirin [Ng 2010], [Sung 2010]. Clinical experience also suggests the utility of pantoprazole for maintenance therapy/secondary prevention in select high-risk patients, such as those with idiopathic ulcers, frequently recurrent ulcers, or a need for continued NSAID use [Feldman 2019a].
Based on international consensus recommendations on the management of patients with nonvariceal upper GI bleeding, a PPI is recommended for maintenance therapy in patients treated for GI bleeding who have a high risk for rebleeding (eg, active bleed, visible vessel, adherent clot) or secondary prophylaxis in patients with a history of GI bleeding who require NSAID therapy [Barkun 2019].
Peptic ulcer disease, treatment of bleeding ulcers
Data from multiple randomized clinical trials, including both open-label and double-blind, randomized trials, in patients with active peptic ulcer bleeding treated with either continuous infusion or intermittent IV pantoprazole after endoscopic hemostasis support the use of either continuous infusion or intermittent pantoprazole for the treatment of this condition [Hsu 2010], [Hung 2007], [Yamada 2012], [Zargar 2006].
Based on international consensus recommendations on the management of patients with nonvariceal upper GI bleeding and ACG guidelines on management of patients with ulcer bleeding, an IV PPI regimen may be considered prior to endoscopy in select patients with a bleeding ulcer and should be used after successful endoscopy in patients with a high risk for rebleeding (eg, active bleed, visible vessel, adherent clot), followed by an oral PPI regimen for maintenance therapy [Barkun 2019], [Laine 2012].
Peptic ulcer disease, treatment of complicated ulcers
Clinical experience suggests the utility of pantoprazole for the treatment of complicated peptic ulcers (perforation, penetration, or gastric outlet obstruction) [Vakil 2020b].
Peptic ulcer disease, treatment of uncomplicated ulcers
Data from randomized, double-blind studies support the use of oral pantoprazole for the treatment of uncomplicated peptic ulcers [Cremer 1995], [Rehner 1995], [Witzel 1995].
Stress ulcer prophylaxis in select critically ill patients
Data from randomized, blinded, placebo-controlled, parallel-group trials in critically ill patients with GI bleeding risk factors found no clinically significant differences in those receiving pantoprazole compared to those receiving placebo [Alhazzani 2017], [Krag 2018], [Selvanderan 2016]. Further evaluation is warranted, particularly to better define risk factors [Barletta 2016].
Based on the Surviving Sepsis Campaign international guidelines for the management of severe sepsis and septic shock, stress ulcer prophylaxis using a PPI is an effective and recommended option in select critically ill patients with GI bleeding risk factors.
Hypersensitivity (eg, anaphylaxis, anaphylactic shock, angioedema, bronchospasm, acute interstitial nephritis, urticaria) to pantoprazole, other substituted benzimidazole proton pump inhibitors, or any component of the formulation; in combination with rilpivirine-containing products.
Canadian labeling: Additional contraindications (not in US labeling): Concomitant use with rilpivirine
Note: Do not administer concomitantly with other antisecretory agents, such as H2-receptor antagonists (H2RAs), prostaglandin analogues (eg, misoprostol), or somatostatin analogues (eg, octreotide), due to decreased acid-inhibitory effects; if another antisecretory agent is needed, allow a sufficient time interval between administration (ie, morning pantoprazole and bedtime H2RA) (ACG [Katz 2013]; Wolfe 2000; Wolfe 2020).
Aspiration prophylaxis in patients undergoing anesthesia (off-label use):
Note: May be considered in patients at high risk for aspiration (ASA 2017).
Oral: 40 mg given the night before surgery and 40 mg given the morning of surgery (Bhattacharyya 2011; Puig 2012).
IV: 40 mg as a single dose 1 hour prior to induction anesthesia (Brown 2019; Memiş 2003; Pisegna 2009; Puig 2012).
Barrett esophagus (off-label use):
Oral: 40 mg once daily; may increase the dose to 40 mg twice daily if needed to eliminate gastroesophageal reflux disease (GERD) symptoms or heal reflux esophagitis. Long-term maintenance therapy is recommended (ACG [Shaheen 2016]; Babic 2015; Spechler 2020).
Dyspepsia, functional (idiopathic or non-ulcer) (off-label use):
Note: For patients who test negative for Helicobacter pylori infection or have persistent symptoms following H. pylori eradication (ACG/CAG [Moayyedi 2017]; Longstreth 2020).
Oral: 20 to 40 mg once daily for a 4- to 8-week trial (Jung 2016; Pinto-Sanchez 2017; van Rensburg 2008); can be continued for a longer duration in patients with symptom improvement. Some experts recommend attempting to discontinue every 6 to 12 months to minimize the long-term risk of therapy (Longstreth 2020).
Gastroesophageal reflux disease, erosive or nonerosive:
Mild/intermittent disease (<2 episodes/week) and no evidence of erosive esophagitis:
Note: Some experts reserve proton pump inhibitors (PPIs) for patients who have residual acid reflux symptoms despite twice-daily H2RA (Kahrilas 2020).
Oral: 20 mg once daily, can increase to 40 mg once daily after 4 to 8 weeks if necessary. Discontinue once asymptomatic for 8 weeks (Kahrilas 2020).
Severe and/or frequent symptoms (≥2 episodes/week), and/or erosive esophagitis:
Oral: 40 mg once daily; once symptoms are controlled, continue for at least 8 weeks (Kahrilas 2020; Province of British Columbia Ministry of Health 2015; Wolfe 2000). Subsequently, patients without severe erosive esophagitis or Barrett esophagus can taper to the lowest dose necessary to control symptoms (and/or switch to an H2RA blocker), then discontinue acid suppression once asymptomatic. Patients with severe erosive esophagitis or Barrett esophagus should continue long-term maintenance therapy with 40 mg once daily (Kahrilas 2020; Ramakrishnan 2002; Spechler 2020).
IV (in patients unable to receive oral medications): 40 mg once daily, then switch to oral when possible (Metz 2000).
Residual symptoms despite 40 mg once daily therapy:
Note: Referral to a specialist is recommended.
Oral: Options include splitting the dose to 20 mg twice daily, increasing the dose to 40 mg twice daily, or switching to another PPI (ACG [Katz 2013]; Fass 2019; Wang 2009).
Helicobacter pylori eradication (off-label use):
Oral: 40 mg or 80 mg twice daily as part of an appropriate combination regimen with antibiotics. Dose depends on the selected regimen (ACG [Chey 2017]; Crowe 2020; Fallone 2016).
Nonsteroidal anti-inflammatory drugs (including aspirin)-induced ulcers, primary prevention (off-label use):
Note: For select patients at moderate or high risk for GI toxicity. These include patients with a history of GI ulcer, on dual antiplatelet therapy (eg, aspirin plus a P2Y12 inhibitor), on concurrent anticoagulant therapy, or with multiple additional risk factors (eg, corticosteroid use, high nonsteroidal anti-inflammatory drug [NSAID] dose, H. pylori infection) (Feldman 2019b; Holmes 2019). For patients on dual antiplatelet therapy, some experts reserve prophylaxis for those with additional risk factors (ACCF/ACG/AHA [Abraham 2010]; ESC [Ibanez 2018]). If present, H. pylori infection should be treated first (ACG [Lanza 2009]; Feldman 2019b).
Oral: 20 to 40 mg once daily for the duration of high-risk NSAID use (Bianchi Porro 2000; Cuisset 2009; Regula 2006; Sibbing 2009).
Peptic ulcer disease, treatment and secondary prevention (off-label use):
Note: For patients on NSAIDs (including aspirin), the NSAID should be discontinued, if possible (Feldman 2019a). If present, H. pylori infection should be treated first; uncomplicated H. pylori–associated ulcers may not need PPI treatment beyond that included in the eradication regimen (Vakil 2019).
Uncomplicated ulcer: Oral: 40 mg once daily. Duration depends on the size, location, and cause of ulcer and ranges from 4 to 8 weeks (Cremer 1995; Rehner 1995; Savarino 1998; Witzel 1995). In patients with refractory or recurrent disease, may increase the dose to 40 mg twice daily (Vakil 2019; Vakil 2020a).
Complicated ulcer (perforation, penetration, or gastric outlet obstruction): Oral, IV: 40 mg twice daily for 4 weeks, followed by 40 mg once daily. Duration depends on the location and etiology of ulcer (Vakil 2020b).
Initial therapy: Note: Optimal pre-endoscopic PPI therapy is uncertain. Some experts suggest initiating high-dose IV PPI with continuous or intermittent dosing in patients with suspected active upper GI bleed prior to endoscopy (Saltzman 2020). Following endoscopy, for patients with high-risk stigmata of recent bleeding (eg, active bleed, visible vessel, adherent clot), a continuous infusion of an IV PPI for at least 72 hours before transitioning to an oral PPI is recommended (Barkun 2019). Patients without high-risk stigmata of recent bleeding can be switched to an oral PPI immediately after endoscopy (Saltzman 2020).
IV: Continuous infusion: Loading dose of 80 mg, followed by 8 mg/hour continuous infusion for a total of 72 hours (Barkun 2019; Sung 2010; van Rensburg 2009; Zargar 2006).
IV: Intermittent dosing: Loading dose of 80 mg, followed by 40 mg every 12 hours (Hsu 2010; Hung 2007; Yamada 2012).
Patients with high-risk stigmata of recent bleeding on endoscopy (following IV PPI therapy): 40 mg twice daily for 14 days, followed by 40 mg once daily (Barkun 2019; Saltzman 2020).
Patients with no high-risk stigmata of recent bleeding on endoscopy: 20 mg once daily (Saltzman 2020).
Duration: The total duration of treatment depends on size, location, and cause of the ulcer and ranges from 4 to 12 weeks (Barkun 2019; Saltzman 2020; Vakil 2019; Vakil 2020a).
Maintenance therapy/secondary prevention: Note: For select high-risk patients (eg, idiopathic ulcers, frequently recurrent ulcers, need for continued NSAID use).
Oral: 20 to 40 mg once daily (Feldman 2019a; Ng 2010; Sung 2010).
Stress ulcer prophylaxis in select critically ill patients (off-label use):
Note: For ICU patients with associated risk factors for GI bleeding (including coagulopathy, mechanical ventilation for >48 hours, traumatic brain injury, history of GI ulceration or bleeding within past year, extensive burns) (Rhodes 2017; Weinhouse 2019).
IV: 40 mg once daily (Alhazzani 2017; Krag 2018; Selvanderan 2016).
Oral or via nasogastric tube: 40 mg once daily (Spirt 2006; Wensel 2009).
Duration: Discontinue prophylaxis once critical illness and modifiable risk factors have resolved (Rhodes 2017; Weinhouse 2019).
Oral: Initial: 80 mg twice daily; if needed, may titrate upward early in therapy to a maximum of 240 mg/day (as either 80 mg three times daily or 120 mg twice daily); once acid output has been controlled, gradual dose reductions are usually possible; reported maintenance dosage range: 40 to 200 mg/day (mean: 116 mg/day); daily doses ≥80 mg are usually given in 2 to 3 divided doses; continue therapy as long as clinically indicated (Bergsland 2020; Metz 2006; Ramdani 2002).
IV (when oral administration is not possible): Initial: 80 mg every 8 to 12 hours; doses up to 240 mg/day (given as 120 mg every 12 hours or 80 mg every 8 hours) have been used for a limited period of time (up to 6 days); switch to oral administration when possible (Lew 2000; Metz 2001).
Discontinuation of therapy: In patients who have received continuous therapy for >6 months, some experts gradually taper therapy until discontinuation to avoid worsening or rebound symptoms. There is no single agreed upon discontinuation strategy. If the patient is receiving 40 mg once or twice daily, some experts decrease the dose by 50% every week. For patients receiving twice-daily dosing, the first dose reduction can be achieved by decreasing to once-daily AM dosing. Once patients are on the lowest dose for 1 week, discontinue therapy (Wolfe 2020). An alternative strategy is to decrease the dose by 50% over 2 to 4 weeks, then discontinue. If the patient is already on the lowest possible dose, alternate-day therapy may be considered (Kim 2018). In addition, as-needed therapy with an H2RA or an antacid can be used during the taper (Haastrup 2014).
Dosage adjustment for concomitant therapy: Significant drug interactions exist, requiring dose/frequency adjustment or avoidance. Consult drug interactions database for more information.
Refer to adult dosing.
Note: Dosing should be based on lean body weight in obese patients; pharmacokinetic studies suggest that obese children ≥6 years and adolescents have higher exposures and slower drug clearance compared to nonobese patients (Shakhnovich 2018; Shakhnovich 2019).
Gastroesophageal reflux disease (GERD), symptomatic (NASPGHAN/ESPGHAN [Rosen 2018]): Limited data available: 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.
Infants, Children, and Adolescents: Oral: 1 to 2 mg/kg/day once daily; maximum daily dose: 40 mg/day.
Erosive esophagitis associated with GERD:
Children 1 to 5 years: Limited data available: Oral: 0.3, 0.6, or 1.2 mg/kg/day once daily for 8 weeks was used in a dose-finding study of 60 patients with histologic or erosive esophagitis. High-dose treatment (1.2 mg/kg/day) was administered as a fixed dose of either: 15 mg for 1-year-olds or 20 mg for 2- to 5-year-olds. Patients with erosive esophagitis (n=4) received either 0.6 or 1.2 mg/kg/day. All patients had symptomatic improvement and patients with erosive esophagitis were healed by week 8; no dose response relationship was demonstrated (Baker 2010).
Children ≥5 years and Adolescents: Oral:
≥15 to <40 kg: 20 mg once daily for up to 8 weeks.
≥40 kg: 40 mg once daily for up to 8 weeks.
Gastric acid suppression; oral therapy not appropriate or tolerated: Limited data available; dosing regimens variable: Note: Dosing based on pharmacokinetic data from 39 pediatric patients (age range: 10 days to 16 years) which has shown doses within this range produce similar AUC as adult patients with comparable dosing; efficacy was not evaluated in either trial (Kearns 2008; Pettersen 2009). Parenteral therapy should be discontinued as soon as the patient tolerates oral therapy.
Weight-based dosing: Children ≥2 years and Adolescents: IV: 0.8 or 1.6 mg/kg once daily; maximum single dose: 80 mg; dosing from a single dose pharmacokinetic study in 18 patients (age range: 2 to 14 years) (Kearns 2008). In the BSA-based dosing trial (Pettersen 2009), the final median dose when standardized to weight was 1.1 mg/kg/day (range: 0.5 to 4.6 mg/kg/day). (Note: The 4.6 mg/kg/day dose was a prescription error; however, the patient experienced no adverse consequences due to high dose). Additionally, some clinicians have used 1 to 2 mg/kg/day in single or divided doses. Note: In a very small trial (n=8), a median dose of 1.1 mg/kg (0.9 to 2.5 mg/kg) produced similar AUC values as adults, but only produced a definable response (gastric pH >4) in one patient; in the remaining seven patients the mean percentage of time with intragastric pH ≥4 was 7.4 % (Pettersen 2005); the pharmacodynamic profile needs further defined (Pettersen 2009).
BSA-based dosing: Infants, Children, and Adolescents: IV: 40 mg/1.73 m2/day; if inadequate response (eg, continued symptoms or target gastric pH not achieved) may titrate up to a maximum dose of 80 mg/1.73 m2/day; dosing based on multidose pharmacokinetic analysis; in the final analysis, the median reported dose was 41.8 mg/1.73 m2/day (range: 19.9 to 140.6 mg/1.73 m2/day) (Note: The 140.6 mg/1.73 m2/day dose was a prescription error; however, the patient experienced no adverse consequences due to high dose) (Pettersen 2009).
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.
40 mg dose: Reconstitute 1 vial with 10 mL of NS; further dilute with 100 mL of D5W, NS, or LR to a final concentration of ~0.4 mg/mL.
80 mg dose: Reconstitute 2 vials each with 10 mL of NS; combine the content of both vials and further dilute with 80 mL of D5W, NS, or LR to a final concentration of ~0.8 mg/mL.
2-minute infusion: Reconstitute with 10 mL of NS to a final concentration of ~4 mg/mL.
2 mg/mL Oral Suspension
A 2 mg/mL pantoprazole oral suspension may be made with pantoprazole tablets, sterile water, and sodium bicarbonate powder. Remove the Protonix imprint from twenty 40 mg tablets with a paper towel dampened with ethanol (improves the look of product). Let tablets air dry. Crush the tablets in a mortar and reduce to a fine powder. Transfer to a 600 mL beaker, and add 340 mL sterile water. Place beaker on a magnetic stirrer. Add 16.8 g of sodium bicarbonate powder and stir for about 20 minutes until the tablet remnants have disintegrated. While stirring, add another 16.8 g of sodium bicarbonate powder and stir for about 5 minutes until powder has dissolved. Add enough sterile water for irrigation to bring the final volume to 400 mL. Mix well. Transfer to amber-colored bottle. Label "shake well" and "refrigerate". Stable for 62 days refrigerated.Dentinger PJ, Swenson CF, and Anaizi NH, “Stability of Pantoprazole in an Extemporaneously Compounded Oral Liquid,” Am J Health Syst Pharm, 2002, 59(10):953-6.12040734
IV: Flush IV line before and after administration with D5W, NS, or LR. In-line filter not required.
2-minute infusion: The volume of reconstituted solution (4 mg/mL) may be administered IV over at least 2 minutes.
15-minute infusion: Infuse over ~15 minutes at a rate of ~7 mL/minute.
Continuous infusion: May also be administered as a continuous infusion for the prevention of rebleeding with in peptic ulcer bleed (off-label use).
Tablet: Should be swallowed whole, do not split, crush, or chew. For most indications, administer 30 to 60 minutes before a meal (preferably); 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). Manufacturer’s labeling states that tablets may be administered with or without food and concomitant administration of antacids do not affect absorption.
Delayed-release oral suspension: Should only be administered in apple juice or applesauce and taken ~30 minutes before a meal; do not chew or crush granules. Do not administer with any other liquid (eg, water) or foods.
Oral administration in applesauce: Sprinkle intact granules on 1 teaspoon of applesauce and swallow within 10 minutes of preparation.
Oral administration in apple juice: Empty intact granules into 5 mL of apple juice, stir for 5 seconds (granules will not dissolve), and swallow immediately after preparation. Rinse container once or twice with apple juice and swallow immediately.
Nasogastric tube administration: Separate the plunger from the barrel of a 60 mL catheter tip syringe and connect to a ≥16 French nasogastric tube. Holding the syringe attached to the tubing as high as possible, empty the contents of the packet into barrel of the syringe, add 10 mL of apple juice and gently tap/shake the barrel of the syringe to help empty the syringe. Add an additional 10 mL of apple juice and gently tap/shake the barrel to help rinse. Repeat rinse at least twice with 10 mL aliquots of apple juice. No granules should remain in the syringe.
Bariatric surgery: Tablet, delayed release: Some institutions may have specific protocols that conflict with these recommendations; refer to institutional protocols as appropriate. Delayed-release tablet should be swallowed whole. Do not chew or crush. Oral suspension formulation is available. If safety and efficacy can be effectively monitored, no change in formulation or administration is required after bariatric surgery; however, for patients with refractory acid reflux, esophagitis, Barrett's esophagus, or ulcer, consider switching to an alternative proton pump inhibitor that is orally disintegrating (ie, lansoprazole Solutab) or a capsule formulation where contents of the capsule may be opened and taken with food (omeprazole, esomeprazole, lansoprazole). If there is inadequate response, consider escalation of therapy to twice a day or conversion to omeprazole/sodium bicarbonate or dexlansoprazole.
IV: Due to EDTA in preparation, zinc supplementation may be needed in patients prone to zinc deficiency.
Oral: Store tablet and oral suspension at 20°C to 25°C (68°F to 77°F); excursions permitted to 15°C to 30°C (59°F to 86°F).
IV: Prior to reconstitution, store at 20°C to 25°C (68°F to 77°F); excursions permitted to 15°C to 30°C (59°F to 86°F). Do not freeze. Protect from light prior to reconstitution; upon reconstitution, protection from light is not required. Do not freeze reconstituted solution. Per manufacturer's labeling, reconstituted solution is stable at room temperature for up to 6 hours; further diluted (admixed) solution in D5W, LR, or NS should be stored at room temperature and used within 24 hours from the time of initial reconstitution. However, studies have shown that reconstituted solution (4 mg/mL) in polypropylene syringes is stable up to 96 hours at room temperature (Johnson 2005). Upon further dilution, the admixed solution should be used within 96 hours from the time of initial reconstitution. The preparation should be stored at 3°C to 5°C (37°F to 41°F) if it is stored beyond 48 hours to minimize discoloration.
Acalabrutinib: Proton Pump Inhibitors may decrease the serum concentration of Acalabrutinib. Avoid combination
Amphetamine: Proton Pump Inhibitors may increase the absorption of Amphetamine. Monitor therapy
Atazanavir: Proton Pump Inhibitors may decrease the serum concentration of Atazanavir. Management: Avoid use in treatment-experienced patients. In treatment-naive patients, administer boosted atazanavir 12 hours after the PPI and the PPI dose should not exceed the equivalent of 20 mg omeprazole. Monitor for reduced atazanavir efficacy. Consider therapy modification

Concerns related to adverse effects:
• Carcinoma: Benign and malignant neoplasia has been observed in long-term (2-year) rodent studies; while not reported in humans, the relevance of these findings in regards to tumorigenicity in humans is not known.
• Clostridioides (formerly Clostridium) 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 specialist for evaluation; most patients improve 4 to 12 weeks after discontinuation of pantoprazole.
• 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 (≥1 year) 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.
• GI infection (eg, Salmonella, Campylobacter): Use of PPIs may increase risk of these infections.
• Hepatic effects: Mild, transient transaminase elevations have been observed.
• 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 pantoprazole may be necessary; magnesium levels typically return to normal within 2 weeks of stopping.
• Infusion-related reactions: Thrombophlebitis and serious hypersensitivity reactions, including anaphylaxis, erythema multiforme, Stevens-Johnson syndrome, and toxic epidermal necrolysis, have been reported with IV administration.
• Interstitial nephritis: Acute interstitial nephritis has been observed in patients taking PPIs; may occur at any time during therapy and is generally due to an idiopathic hypersensitivity reaction. Discontinue if acute interstitial nephritis develops.
• 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).
• Gastric malignancy: Relief of symptoms does not preclude the presence of a gastric malignancy.
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. Of the PPIs, pantoprazole has the lowest degree of CYP2C19 inhibition in vitro (Li 2004) and has been shown to have less effect on conversion of clopidogrel to its active metabolite compared to omeprazole (Angiolillo 2011). 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:
• Edetate sodium (EDTA): Some dosage forms may contain edetate sodium; use caution in patients who are at risk for zinc deficiency if other EDTA-containing solutions are coadministered.
• Polysorbate 80: Some dosage forms may contain polysorbate 80 (also known as Tweens). Hypersensitivity reactions, usually a delayed reaction, have been reported following exposure to pharmaceutical products containing polysorbate 80 in certain individuals (Isaksson 2002; Lucente 2000; Shelley 1995). Thrombocytopenia, ascites, pulmonary deterioration, and renal and hepatic failure have been reported in premature neonates after receiving parenteral products containing polysorbate 80 (Alade 1986; CDC 1984). See manufacturer's labeling.
• 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 pantoprazole 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.
Bone loss and fractures, CDAD, magnesium (baseline and periodically thereafter), and serum gastrin levels
Hypersecretory disorders: Acid output measurements, target level <10 mEq/hour (<5 mEq/hour if prior gastric acid-reducing surgery)
Recommendations for the treatment of gastroesophageal reflux disease in pregnancy are available. As in nonpregnant patients, lifestyle modifications followed by other medications are the initial treatments (Body 2016; Huerta-Iga 2016; Katz 2013; van der Woude 2014). Based on available data, PPIs may be used when clinically indicated (Body 2016; Matok 2012; Pasternak 2010; van der Woude 2014).
