  • Fundic Gland Polyps [see Warnings and Precautions (5.10)] 6.1 Clinical Trials Experience The adverse reaction profiles for Pantoprazole Sodium For Delayed-Release Oral Suspension and Pantoprazole Sodium Delayed-Release Tablets are similar. 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 clinical practice. Adults Safety in nine randomized comparative US clinical trials in patients with GERD included 1,473 patients on oral pantoprazole sodium (20 mg or 40 mg), 299 patients on an H 2-receptor antagonist, 46 patients on another PPI, and 82 patients on placebo. The most frequently occurring adverse reactions are listed in Table 3. Table 3: Adverse Reactions Reported in Clinical Trials of Adult Patients with GERD at a Frequency of >2% Pantoprazole sodium (n=1473) % Comparators (n=345) % Placebo (n=82) % Headache 12.2 12.8 8.5 Diarrhea 8.8 9.6 4.9 Nausea 7.0 5.2 9.8 Abdominal pain 6.2 4.1 6.1 Vomiting Flatulence 4.3 3.9 3.5 2.9 2.4 3.7 Dizziness 3.0 2.9 1.2 Arthralgia 2.8 1.4 1.2 Additional adverse reactions that were reported for pantoprazole sodium in clinical trials with a frequency of ≤2% are listed below by body system: Body as a Whole: allergic reaction, pyrexia, photosensitivity reaction, facial edema Gastrointestinal: constipation, dry mouth, hepatitis Hematologic: leukopenia, thrombocytopenia Metabolic/Nutritional: elevated CK (creatine kinase), generalized edema, elevated triglycerides, liver enzymes elevated Musculoskeletal: myalgia Nervous: depression, vertigo Skin and Appendages: urticaria, rash, pruritus Special Senses: blurred vision Pediatric Patients Safety of pantoprazole sodium in the treatment of EE associated with GERD was evaluated in pediatric patients ages 1 year through 16 years in three clinical trials. Safety trials involved pediatric patients with EE; however, as EE is uncommon in the pediatric population, 249 pediatric patients with endoscopically-proven or symptomatic GERD were also evaluated. All adult adverse reactions to pantoprazole sodium are considered relevant to pediatric patients. In patients ages 1 year through 16 years, the most commonly reported (>4%) adverse reactions include: URI, headache, fever, diarrhea, vomiting, rash, and abdominal pain. For safety information in patients less than 1 year of age see Use in Specific Populations ( 8.4). Additional adverse reactions that were reported for pantoprazole sodium in pediatric patients in clinical trials with a frequency of ≤4% are listed below by body system: Body as a Whole: allergic reaction, facial edema Gastrointestinal: constipation, flatulence, nausea Metabolic/Nutritional: elevated triglycerides, elevated liver enzymes, elevated CK (creatine kinase) Musculoskeletal: arthralgia, myalgia Nervous: dizziness, vertigo Skin and Appendages: urticaria The following adverse reactions seen in adults in clinical trials were not reported in pediatric patients in clinical trials, but are considered relevant to pediatric patients: photosensitivity reaction, dry mouth, hepatitis, thrombocytopenia, generalized edema, depression, pruritus, leukopenia, and blurred vision.

    • Drug Interactions

    Table 4 includes drugs with clinically important drug interactions and interaction with diagnostics when administered concomitantly with pantoprazole sodium and instructions for preventing or managing them. Consult the labeling of concomitantly used drugs to obtain further information about interactions with PPIs. Table 4: Clinically Relevant Interactions Affecting Drugs Co-Administered with Pantoprazole Sodium 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 pantoprazole may reduce antiviral effect and promote the development of drug resistance.
  • Increased exposure of other antiretroviral drugs (e.g., saquinavir) when used concomitantly with pantoprazole may increase toxicity of the antiretroviral drugs.
  • There are other antiretroviral drugs which do not result in clinically relevant interactions with pantoprazole. Intervention: Rilpivirine-containing products: Concomitant use with pantoprazole sodium is contraindicated [see Contraindications ( 4)] . See prescribing information. Atazanavir: See prescribing information for atazanavir for dosing information. Nelfinavir: Avoid concomitant use with pantoprazole sodium. 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, including pantoprazole, 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. Clopidogrel Clinical Impact: Concomitant administration of pantoprazole and clopidogrel in healthy subjects had no clinically important effect on exposure to the active metabolite of clopidogrel or clopidogrel-induced platelet inhibition [see Clinical Pharmacology ( 12.3)]. Intervention: No dose adjustment of clopidogrel is necessary when administered with an approved dose of pantoprazole sodium. Methotrexate Clinical Impact: Concomitant use of PPIs 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 ( 5.13)] . Intervention: A temporary withdrawal of pantoprazole sodium may be considered in some patients receiving high-dose methotrexate. Drugs Dependent on Gastric pH for Absorption (e.g., iron salts, erlotinib,...

    • Contraindications

  • Pantoprazole sodium delayed-release tablets are contraindicated in patients with known hypersensitivity to any component of the formulation or any substituted benzimidazole. Hypersensitivity reactions may include anaphylaxis, anaphylactic shock, angioedema, bronchospasm, acute tubulointerstitial nephritis, and urticaria [see Warnings and Precautions ( 5.2), Adverse Reactions ( 6)].
  • Proton pump inhibitors (PPIs), including pantoprazole sodium delayed-release tablets, are contraindicated in patients receiving rilpivirine-containing products [see Drug Interactions ( 7)].

    • Overdosage

    Experience in patients taking very high doses of pantoprazole sodium (greater than 240 mg) is limited. Spontaneous post-marketing reports of overdose are generally within the known safety profile of pantoprazole sodium. Pantoprazole is not removed by hemodialysis. In case of overdosage, treatment should be symptomatic and supportive. Single oral doses of pantoprazole at 709 mg/kg, 798 mg/kg, and 887 mg/kg were lethal to mice, rats, and dogs, respectively. The symptoms of acute toxicity were hypoactivity, ataxia, hunched sitting, limb-splay, lateral position, segregation, absence of ear reflex, and tremor. If overexposure to pantoprazole sodium occurs, call your Poison Control Center at 1-800-222-1222 for current information on the management of poisoning or overdosage.
