4.1 Therapeutic indications
MYLAN PANTOPRAZOLE 40 mg is indicated for the short-term treatment of duodenal ulcer, gastric ulcer and reflux oesophagitis. If the duodenal ulcer has been demonstrated to be associated with Helicobacter pylori infection, MYLAN PANTOPRAZOLE 40 mg used in combination with appropriate antibiotics may be useful.
MYLAN PANTOPRAZOLE 40 mg is indicated for the treatment of Zollinger-Ellison Syndrome.
MYLAN PANTOPRAZOLE 20 mg is indicated for the symptomatic improvement (e.g. heartburn, acid regurgitation, pain on swallowing) and healing of mild gastro-oesophageal reflux disease (GERD).
MYLAN PANTOPRAZOLE 20 mg is indicated for long-term management and prevention of relapse in gastro-oesophageal reflux disease (GERD).
MYLAN PANTOPRAZOLE 20 mg is indicated for the prevention of gastroduodenal lesions and dyspeptic symptoms induced by non selective non steroidal anti-inflammatory drugs (NSAIDu2019s) in patients at risk, and with a need for continuous NSAID treatment.
4.2 Posology and method of administration
The recommended once daily dosage of pantoprazole should be taken in the morning. MYLAN PANTOPRAZOLE 20 mg and MYLAN PANTOPRAZOLE 40 mg should be swallowed whole with a little water either before or during breakfast.
Duodenal ulcer
The recommended oral dosage is 40 mg of MYLAN PANTOPRAZOLE once daily in the morning for 2 to 4 weeks. If the duodenal ulcer has been demonstrated to be associated with Helicobacter pylori infection, MYLAN PANTOPRAZOLE 40 mg used in combination with appropriate antibiotics may be useful.
Gastric ulcer
The recommended oral dosage is 40 mg of MYLAN PANTOPRAZOLE once daily in the morning for 4 to 8 weeks. In the case of a suspected gastric ulcer, malignancy of the ulcer should be excluded, as treatment could conceal the symptoms and may delay diagnosis.
Reflux oesophagitis
The recommended oral dosage is 40 mg of MYLAN PANTOPRAZOLE once daily in the morning for 4 to 8 weeks.
Zollinger-Ellison Syndrome
For the management of Zollinger-Ellison Syndrome, patients should start their treatment with a daily dose of 80 mg of MYLAN PANTOPRAZOLE (two tablets of MYLAN PANTOPRAZOLE 40 mg). Thereafter, the dose can be titrated up or down, as needed, using measurements of gastric acid secretion as a guide. With doses above 80 mg daily, the dose should be divided and given twice daily.
Mild Gastro-oesophageal Reflux Disease (GERD)
The recommended oral dosage is 20 mg of MYLAN PANTOPRAZOLE per day. A 4-week period is usually required for healing of mild GERD. If symptom control has not been achieved after four weeks of treatment with the prescribed daily dose, further investigation is recommended. In patients with healed reflux disease, recurring symptoms can be controlled using an on-demand regimen of 20 mg once daily when required.
Long-term management and prevention of relapse in GERD
For long-term management a maintenance dose of one MYLAN PANTOPRAZOLE 20 mg tablet per day is recommended, increasing to 40 mg of MYLAN PANTOPRAZOLE per day if a relapse occurs. After healing of the relapse, the dosage can be reduced to 20 mg of MYLAN PANTOPRAZOLE. Experience with long-term administration is limited.
For prevention of gastro-duodenal lesions and dyspeptic symptoms induced by non selective non steroidal anti-inflammatory medicines (NSAIDu2019s) in patients at risk and with a need for continuous NSAID treatment, the recommended oral dose is one MYLAN PANTOPRAZOLE 20 mg tablet per day.
Elderly patients
No dosage adjustment is necessary in the elderly.
Impaired renal and liver function
No dosage adjustment is required in the presence of impaired renal function. A daily dose of 20 mg of MYLAN PANTOPRAZOLE should not be exceeded in patients with mild to moderately severe liver impairment (see Pharmacokinetic Properties and WARNINGS AND SPECIAL PRECAUTIONS).
4.3 Contraindications
Hypersensitivity to pantoprazole or any of the ingredients of MYLAN PANTOPRAZOLE tablets. Safety and efficacy in children have not been established. Severely impaired liver function (see under DOSAGE AND DIRECTIONS FOR USE). Co-administration with atazanavir (see INTERACTIONS).
4.4 Special warnings and precautions for use
In patients with severe liver impairment the liver enzymes should be monitored regularly during treatment with MYLAN PANTOPRAZOLE, particularly on long-term use. In the case of a rise of the liver enzymes MYLAN PANTOPRAZOLE should be discontinued.
MYLAN PANTOPRAZOLE is not indicated for mild gastro-intestinal complaints such as nervous dyspepsia.
Prior to treatment, the possibility of malignancy of gastric ulcer or a malignant disease of the oesophagus should be excluded, as the treatment with MYLAN PANTOPRAZOLE may alleviate the symptoms of malignant ulcers and can thus delay diagnosis.
Diagnosis of reflux oesophagitis should be confirmed by endoscopy.
Daily treatment with any acid-blocking medicines over a long period of time (e.g. longer than 3 years) may lead to malabsorption of cyanocobalamin caused by hypo- or achlorhydria. Rare cases of cyanocobalamin deficiency under acid-blocking therapy have been reported in the literature. This should be considered when respective clinical symptoms are observed.
Use of MYLAN PANTOPRAZOLE 20 mg as preventative of gastroduodenal ulcers, induced by non-selective non steroidal anti-inflammatory drugs (NSAIDu2019s) should be restricted to patients who require continued NSAID treatment and have an increased risk to develop gastro-intestinal complications.
MYLAN PANTOPRAZOLE 20 mg may increase the risk of subclinical acute or chronic interstitial nephritis associated with proton pump inhibitors (PPIs) leading to chronic renal inflammation and reduced renal function (tubular injury being u201ctubulointerstitial nephritisu201d).
Information about the lactose content in MYLAN PANTOPRAZOLE: MYLAN PANTOPRAZOLE contains lactose. Patients with the rare hereditary conditions of galactose intolerance e.g. galactosaemia, Lapp lactase deficiency, glucose-galactose malabsorption or fructose intolerance should not take MYLAN PANTOPRAZOLE.
4.5 Interactions with other medicines
Concomitant intake of food has no influence on the bioavailability. Pantoprazole may reduce or increase the absorption of medicines whose bioavailability is pH-dependant e.g. ketoconazole, ampicillin esters and iron salts.
Atazanavir: It has been shown that co-administration of atazanavir/ritonavir with omeprazole or atazanavir with lansoprazole resulted in a substantial reduction in the bioavailability of atazanavir. The absorption of atazanavir is pH-dependent. Therefore, pantoprazole must not be co-administered with atazanavir (see CONTRA - INDICATIONS).
Pantoprazole, although metabolised by hepatic cytochrome P450-enzyme systems, does not appear to either inhibit or induce cytochrome P450-enzyme activity. However, an interaction of MYLAN PANTOPRAZOLE with other medicines which are metabolised using the same enzyme system cannot be excluded.
No clinically significant interactions were observed after concomitant administration of pantoprazole with either antipyrine, diazepam, theophylline, digoxin, phenytoin, carbamazepine, diclofenac, nifedipine, piroxicam, metoprolol, glibenclamide, ethanol, caffeine, warfarin or oral contraceptives. However, the response to anti-coagulants, such as warfarin, may be affected by any concomitant medication. Therefore, monitoring the patient with additional PT (prothrombin time) / INR (International normalized ratio) determinations when MYLAN PANTOPRAZOLE is initiated, discontinued or taken irregularly would be a good practice.
There were no interactions with concomitantly administered antacids.
4.6 Fertility, pregnancy and lactation
Safety in pregnancy and during lactation has not been established.

Musculoskeletal, connective tissue and bone disorders:
Less frequent: Arthralgia, myalgia
Renal and urinary disorders:
Less frequent: Interstitial nephritis (with possible progression to renal failure)
General disorders and administrative site conditions:
Less frequent: Peripheral oedema
Post-marketing exposure:
The renal effect of proton pump inhibitors (PPIs) may progress to renal failure as it is not necessarily reversed when treatment is discontinued. There is an increased risk of subclinical acute or chronic interstitial nephritis associated with proton pump inhibitors (PPIs) leading to chronic renal inflammation and reduced renal function (tubular injury being u201ctubulointerstitial nephritisu201d).
Acute tubulointerstitial nephritis is characterised by an inflammatory reaction within the tubulointerstitial space of the kidney. Acute interstitial inflammatory reactions are associated with damage to the tubulointerstitium, leading to acute kidney injury. Interstitial nephritis may lead to renal failure.
4.9 Overdose
There are no known symptoms of overdosage in man. No specific therapeutic recommendation can be made in cases of overdosage.
