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).

Pantoprazole sodium is contraindicated in patients with known hypersensitivity reactions including anaphylaxis to the formulation or any substituted benzimidazole. Hypersensitivity reactions may include anaphylaxis, anaphylactic shock, angioedema, bronchospasm, acute tubulointerstitial nephritis, and urticaria [see (5.2 , 5.4 ) and (6) ] . Proton pump inhibitors (PPIs), including pantoprazole sodium, are contraindicated in patients receiving rilpivirine-containing products [see (7) ] . Known hypersensitivity to any component of the formulation or to substituted benzimidazoles. ( 4 ) Patients receiving rilpivirine-containing products. ( 4 , 7 )

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. ( 5.1 ) Injection Site Reactions : Thrombophlebitis is associated with the administration of intravenous pantoprazole sodium. Assess the patient and remove the catheter if clinically indicated. ( 5.2 ) Potential Exacerbation of Zinc Deficiency : Consider zinc supplementation in patients who are prone to zinc deficiency. Caution should be used when other EDTA containing products are also co-administered intravenously. ( 5.3 ) Acute Tubulointerstitial Nephritis : Discontinue treatment and evaluate patients. ( 5.4 ) Clostridioides difficile -Associated Diarrhea : PPI therapy may be associated with increased risk. ( 5.5 ) 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. ( 5.6 ) Severe Cutaneous : Discontinue at the first signs or symptoms of severe cutaneous or other signs of hypersensitivity and consider further evaluation. ( 5.7 ) Cutaneous and Systemic Lupus Erythematosus : Mostly cutaneous; new onset or exacerbation of existing disease; discontinue treatment and refer to specialist for evaluation. ( 5.8 ) Hepatic Effects : Elevations of transaminases observed. ( 5.9 ) Hypomagnesemia and Mineral Metabolism : Reported rarely with prolonged treatment with PPIs. ( 5.10 ) Fundic Gland Polyp s : Risk increases with long-term use, especially beyond one year. Use the shortest duration of therapy. ( 5.11 ) 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 Injection Site Reactions Thrombophlebitis was associated with the administration of pantoprazole sodium.

See the full prescribing information for a list of clinically important . ( 7 ) Table 3 includes drugs with clinically important 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 3: Clinically Relevant Interactions Affecting Drugs Co-Administered with Pantoprazole Sodium and Interaction 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 sodium 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 sodium may increase toxicity of the antiretroviral drugs. There are other antiretroviral drugs which do not result in clinically relevant interactions with pantoprazole sodium. Intervention: Rilpivirine-containing products: Concomitant use with pantoprazole sodium is contraindicated [see (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 sodium, 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 sodium 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....
