Pantoprazole sodium delayed-release tablets are indicated for: Pantoprazole sodium is a proton pump inhibitor (PPI) indicated for the following: Short-Term Treatment of Erosive Esophagitis Associated with Gastroesophageal Reflux Disease (GERD) ( 1.1 ) Maintenance of Healing of Erosive Esophagitis ( 1.2 ) Pathological Hypersecretory Conditions Including Zollinger-Ellison (ZE) Syndrome ( 1.3 ) 1.1 Short-Term Treatment of Erosive Esophagitis Associated With Gastroesophageal Reflux Disease (GERD) Pantoprazole sodium delayed-release tablets are indicated in adults and pediatric patients five years of age and older for the short-term treatment (up to 8 weeks) in the healing and symptomatic relief of erosive esophagitis (EE). For those adult patients who have not healed after 8 weeks of treatment, an additional 8-week course of pantoprazole sodium delayed-release tablets may be considered. Safety of treatment beyond 8 weeks in pediatric patients has not been established. 1.2 Maintenance of Healing of Erosive Esophagitis Pantoprazole sodium delayed-release tablets are indicated for maintenance of healing of EE and reduction in relapse rates of daytime and nighttime heartburn symptoms in adult patients with GERD. Controlled studies did not extend beyond 12 months. 1.3 Pathological Hypersecretory Conditions Including Zollinger-Ellison Syndrome Pantoprazole sodium delayed-release tablets are indicated for the long-term treatment of pathological hypersecretory conditions, including Zollinger-Ellison (ZE) Syndrome.
About this medicine
The active ingredient in pantoprazole sodium delayed-release tablets USP, a PPI, is a substituted benzimidazole, sodium 5-(difluoromethoxy)-2-[[(3,4-dimethoxy-2-pyridinyl)methyl] sulfinyl]-1H- benzimidazole sesquihydrate, a compound that inhibits gastric acid secretion. Its molecular formula is C 16 H 14 F 2 N 3 NaO 4 S x 1.5 H 2 O, with a molecular weight of 432.4. The structural formula is: Pantoprazole sodium sesquihydrate is a white to cream color powder and is racemic. Pantoprazole has weakly basic and acidic properties. Pantoprazole sodium sesquihydrate is freely soluble in water and ethanol. The stability of the compound in aqueous solution is pH-dependent. The rate of degradation increases with decreasing pH. At ambient temperature, the degradation half-life is approximately 2.8 hours at pH 5 and approximately 220 hours at pH 7.8. Pantoprazole sodium USP is supplied as a delayed-release tablet, available in two strengths 20 mg pantoprazole (equivalent to 22.6 mg of pantoprazole sodium sesquihydrate) and 40 mg pantoprazole (equivalent to 45.1 mg of pantoprazole sodium sesquihydrate).

How it works
12.1 Mechanism of Action Pantoprazole is a PPI that suppresses the final step in gastric acid production by covalently binding to the (H + , K + )-ATPase enzyme system at the secretory surface of the gastric parietal cell. This effect leads to inhibition of both basal and stimulated gastric acid secretion, irrespective of the stimulus. The binding to the (H + , K + )-ATPase results in a duration of antisecretory effect that persists longer than 24 hours for all doses tested (20 mg to 120 mg).
Who should not take it
• 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 ) ]. Patients with known hypersensitivity to any component of the formulation or to substituted benzimidazoles ( 4) Patients receiving rilpivirine-containing products ( 4 , 7 )
Warnings and cautions
• Gastric Malignancy : In adults, symptomatic response does not preclude 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 of Clostridium difficile -associated diarrhea. ( 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 pantoprazole sodium and refer to specialist for evaluation. ( 5.6 ) • Cyanocobalamin (Vitamin B-12) Deficiency : Daily long-term use (e.g., longer than 3 years) may lead to malabsorption or a deficiency of cyanocobalamin. ( 5.7 ) • Hypomagnesemia and Mineral metabolism: Reported rarely with prolonged treatment with PPIs. ( 5.8 ) • Fundic Gland Polyps : Risk increases with long-term use, especially beyond one year. Use the shortest duration of therapy. ( 5.10 ) 5.1 Presence of Gastric Malignancy In adults, symptomatic response to therapy with pantoprazole sodium 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). […]

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 B-12) Deficiency [see Warnings and Precautions (5.7) ] • Hypomagnesemia and Mineral Metabolism [see Warnings and Precautions (5.8) ] • Fundic Gland Polyps [see Warnings and Precautions (5.10) ] Most common adverse reactions are: For adult use (>2%): headache, diarrhea, nausea, abdominal pain, vomiting, flatulence, dizziness, and arthralgia. ( 6.1 ) For pediatric use (>4%): URI, headache, fever, diarrhea, vomiting, rash, and abdominal pain. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Dr. Reddy’s Laboratories, Inc. at 1-888-375-3784 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch . 6.1 Clinical Trials Experience The adverse reaction profiles for pantoprazole sodium 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. […]
Interactions with other medicines
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. […]
Use in specific groups
Pregnancy: Based on animal data, may cause fetal harm. ( 8.1 ) 8.1 Pregnancy Risk Summary Available data from published observational studies did not demonstrate an association of major malformations or other adverse pregnancy outcomes with pantoprazole. In animal reproduction studies, no evidence of adverse development outcomes was observed with pantoprazole. Reproduction studies have been performed in rats at oral doses up to 450 mg/kg/day (about 88 times the recommended human dose) and rabbits at oral doses up to 40 mg/kg/day (about 16 times the recommended human dose) with administration of pantoprazole during organogenesis in pregnant animals and have revealed no evidence of harm to the fetus due to pantoprazole in this study (see Data) . A pre-and postnatal development toxicity study in rats with additional endpoints to evaluate the effect on bone development was performed with pantoprazole sodium. Oral pantoprazole doses of 5, 15, and 30 mg/kg/day (approximately 1, 3, and 6 times the human dose of 40 mg/day) were administered to pregnant females from gestation day (GD) 6 through lactation day (LD) 21. Changes in bone morphology were observed in pups exposed to pantoprazole in utero and through milk during the period of lactation as well as by oral dosing from postnatal day (PND) 4 through PND 21 [see Use in Specific Populations ( 8.4 )]. There were no drug-related findings in maternal animals. Advise pregnant women of the potential risk of fetal harm. 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 U.S. general population, the estimated background risk of major birth defects and miscarriage in the clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively. Data Human Data Available data from published observational studies failed to demonstrate an association of adverse pregnancy-related outcomes and pantoprazole use. Methodological limitations of these observational studies cannot definitely establish or exclude any drug-associated risk during pregnancy. […]
If too much is taken
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.
