Contraindications

• Hypersensitivity to drug or any substituted benzimidazole

Precautions

Use cautiously in:
• severe hepatic disease
• atrophic gastritis with long-term use
• increased risk of osteoporosis-related hip, wrist, or spine fractures with long-term use or multiple daily doses
• concurrent use of atazanavir, nelfi-navir, or methotrexate
• pregnant or breastfeeding patients
• children.

Administration

• Be aware that oral granules may be mixed with applesauce or apple juice and given 30 minutes before a meal. Once mixed, give drug within 10 minutes.
• Know that oral granules may be mixed with 10 ml apple juice and administered into nasogastric tube using 60-ml catheter-tip syringe. Rinse syringe with additional apple juice so that no granules remain in syringe.
• For I.V. administration, use in-line filter provided. If Y-site is used, place filter below Y-site closest to patient.
• Dilute I.V. form with 10 ml of normal saline solution; further dilute in dextrose 5% in water, normal saline solution, or lactated Ringer's solution, as directed. Give over 15 minutes at a rate no faster than 3 mg/minute.
• Don't give I.V. form with other I.V. solutions.
• Know that I.V. form is indicated for short-term treatment of GERD in patients with history of erosive esophagitis as alternative to P.O. therapy.
• Be aware that symptomatic response doesn't rule out gastric cancer.

Interactions

Drug-drug.Ampicillin, cyanocobalamin, digoxin, iron salts, ketoconazole: delayed absorption of these drugs Atazanavir, nelfinavir: substantially decreased atazanavir or nelfinavir plasma concentration with loss of therapeutic effect and development of drug resistance

Clarithromycin, diazepam, flurazepam, phenytoin, triazolam: increased panto-prazole blood level

Sucralfate: delayed pantoprazole absorption

Warfarin: increased bleeding

Drug-diagnostic tests.Aspartate aminotransferase, glucose: increased levels

Tetrahydrocannabinol test: false-positive result

Patient monitoring

• Assess for symptomatic improvement.
• Monitor blood glucose level in diabetic patient.

Patient teaching

• Tell patient to swallow delayed-release tablets whole without crushing, chewing, or splitting.
• Tell patient he may take tablets with or without food.
• Explain that antacids don't affect drug absorption.
• Instruct diabetic patients to monitor blood glucose level carefully and stay alert for signs and symptoms of hyperglycemia.
• As appropriate, review all other significant adverse reactions and interactions, especially those related to the drugs and tests mentioned above.
