Included as part of PRECAUTIONS section.


Sequelae of symptomatic response

Symptomatic response to pantoprazole therapy does
does not exclude the presence of malignant neoplasms of the stomach.

Hypersensitivity and severe skin reactions

Anaphylaxis and other serious reactions such as erythema
multiforme, Stevens-Johnson syndrome and toxic epidermal necrolysis (TEN) have
reported with the use of intravenous pantoprazole. It may require an emergency
treatment .

Injection site reactions

Thrombophlebitis has been associated with administration
intravenous pantoprazole.

Potential to exacerbate zinc deficiency

PROTONIX contains disodium edetate (salt form
EDTA), a chelator of metal ions, including zinc. Therefore, zinc supplements
should be considered in patients treated with PROTONIX I. V. for injection who
susceptible to zinc deficiency. Caution should be exercised when using other EDTA-containing
products are also administered intravenously.

Clostridium Difficile associated diarrhea

Published observational studies show that PPI therapy
how PROTONIX may be associated with an increased risk of Clostridium
associated diarrhea, especially in hospitalized patients. This
the diagnosis should be considered in diarrhea that does not improve.

Patients should use the lowest dose and shortest duration
PPI therapy appropriate to the condition being treated.

Broken bones

Several published observational studies suggest this
proton pump inhibitor (PPI) therapy may be associated with an increased risk
with fractures of the hip, wrist or spine associated with osteoporosis. Risk
the fracture was enlarged in patients treated with a high dose, defined as multiple
daily doses and long-term PPI therapy (a year or more). Patients should use
lowest dose and shortest duration of PPI therapy consistent with
the condition is being treated. Patients at risk of fractures associated with osteoporosis
should be administered in accordance with established treatment guidelines.

Hepatic effects

Mild, transient increases in transaminases have been
observed in clinical studies. The clinical significance of this discovery in
the large population of subjects receiving intravenous pantoprazole is unknown. .


Hypomagnesemia, symptomatic and asymptomatic, was
rarely reported in patients treated with PPIs for at least three months, and in
most cases after a year of therapy. Serious adverse events include tetany
arrhythmias and seizures. In most patients, treatment of hypomagnesaemia
necessary replacement of magnesium and discontinuation of PPI

For patients who are expected to be on long-term treatment or who
take PPIs with drugs such as digoxin or drugs that can cause
hypomagnesemia (eg. , diuretics), healthcare professionals may consider
monitoring magnesium levels prior to initiating PPI treatment, and

Interference with urine screen for THC

Can produce false positive urinalysis for THC


Simultaneous use of protonix with methotrexate

Literature suggests that concomitant use of PPIs with
methotrexate (mainly at high doses;

times the recommended human dose depending on body surface area) and identified
there is no evidence of impaired fertility or harm to the fetus due to pantoprazole. There
however, there are no adequate and well-controlled studies in pregnant women.
Because animal reproduction studies don’t always predict humans
In response, this medication should be used during pregnancy only if clearly needed.

Nursing mothers

Pantoprazole and its metabolites are excreted in milk
rats. Excretion of pantoprazole in breast milk was found in a study a
single mother after a single dose of 40 mg. Clinical relevance
this find is unknown. Many drugs that are excreted in breast milk have
potential for serious adverse reactions in infants. Based
carcinogenic potential shown for pantoprazole in rodent carcinogenicity
research, a decision must be made whether to terminate care or
stop taking the drug, taking into account the benefits of the drug for

Pediatric use

Safety and effectiveness of PROTONIX I.V. in pediatric
patients were not created.

Geriatric use

No age difference in safety profile
intravenous pantoprazole has been seen in international trials involving 86 elderly people
(≥ 65 years) and 200 young (<65 years) patients with erosive esophagitis associated with GERD. The frequency of healing of esophagitis in 107 elderly patients (≥ 65 years) treated with oral pantoprazole in the US, clinical trials were similar to those found in patients under that age out of 65. The frequency of occurrence of adverse events and laboratory abnormalities in
patients aged 65 years and older were similar to those associated with patients
younger than 65 years old.


No gender difference in safety profile
intravenous pantoprazole was seen in an international trial involving 166 men
and 120 women with erosive esophagitis associated with GERD. Erosion
healing rate of esophagitis in 221 women treated with oral pantoprazole in the US
clinical trials were similar to those found in men. Incidence rates
adverse reactions were also similar for men and women.

Liver failure

Doses above 40 mg/day have not been studied in
patients with liver failure.

Why is it prescribed, side effects

According to doctors, diseases of the digestive system are diseases of civilization. Each person at least once faced such manifestations as abdominal pain, heartburn, belching, bloating, nausea, vomiting, diarrhea, constipation. Gastrointestinal diseases in terms of the number of hospitalizations rank third after pregnancy and cardiovascular diseases.

According to clinical guidelines in the complex therapy of gastric ulcers and gastroesophageal reflux disease (GERD), drugs from the PPI group – proton pump inhibitors are used. Using the example of the drug Pantoprazole, we analyze how such drugs “work” in the body, what they help with and what side effects they have. Compare Pantoprazole with Omeprazole, Rabeprazole and Nolpaza.

Pantoprazole: what helps

Hydrochloric acid, contained in gastric juice, stimulates the production of digestive enzymes, activates gastric motility and destroys pathogens that come with food. It is produced in the parietal cells of the gastric mucosa, and the proton pump enzyme controls this process.

Excessive secretion of hydrochloric acid is dangerous for the mucous membrane of the esophagus, stomach and duodenum. To reduce its production, Pantoprazole is prescribed, which blocks the action of the proton pump and reduces the aggressive effect of gastric juice on the gastrointestinal mucosa.

All items Pantoprazole

Pantoprazole What is it used for

What is Pantoprazole used for? Under what diseases and conditions is it necessary to reduce the secretion of hydrochloric acid? Before answering the questions, we clarify that the indications for the use of the drug depend on the dosage. Pantoprazole tablets are produced in two types:

1. Pantoprazole 20 mg is indicated for the relief of heartburn and regurgitation in GERD in adults. The drug reduces the aggressiveness of gastric juice, which is thrown into the esophagus and prevents the formation of erosion, ulcers and burns.

2. Pantoprazole 40 mg tablets are used for:

  • exacerbation of gastric and duodenal ulcers to allow them to heal;
  • erosive gastritis, including those associated with the use of non-steroidal anti-inflammatory drugs, to protect the mucous membrane;
  • complex eradication of the bacterium Helicobacter pylori, which becomes more sensitive to antibiotics at elevated pH;
  • Zollinger-Ellison syndrome to prevent the formation of erosions and ulcers.

Pantoprazole: side effects

If the drug is used according to indications and in accordance with the instructions, side effects are rare. Headache and diarrhea were reported in only 1% of patients. Also possible:

  • dizziness;
  • benign polyps of gastric glands;
  • bloating, constipation;
  • dry mouth, nausea, vomiting;
  • abdominal pain and discomfort;
  • dermatitis, pruritus, rash;
  • fractures.

Pantoprazole or Omeprazole: which is better?

Omeprazole is the first and most studied proton pump inhibitor. Indications for use are generally similar to those of Pantoprazole. The main difference is that omeprazole at a dose of 20 mg is approved for the treatment of children from 2 years of age with GERD and from 4 years of age in the eradication of Helicobacter pylori, and Pantoprazole is indicated only for adult patients from 18 years of age.

Preparations differ in the form of release. Omeprazole is produced in the form of microcapsules enclosed in an enteric shell and placed in a capsule. Pantoprazole is an enteric coated tablet. Omeprazole capsules can be dissolved in acidified water, juice or fruit puree. In this form, they are convenient for children and patients with difficulty swallowing.

Omeprazole is more likely than pantoprazole to cause headache, drowsiness, lethargy and gastrointestinal side effects, has more interactions with other drugs

What analogues have in common: both drugs are taken before meals, they act 24 hours after the start of administration and are compatible with antacids. But, despite the similarity of action, patients should not independently decide what to take – Omeprazole or Pantoprazole. To do this, you need to consult a doctor, as the drugs have differences.

Pantoprazole or Rabeprazole: which is better?

Rabeprazole is also a PPI and has a number of advantages over Pantoprazole: it works up to 48 hours, it is allowed for children from 12 years of age with GERD at a dosage of 20 mg, it can be used regardless of food intake.

Another “positive” difference between Rabeprazole is that it is active at almost any pH of gastric juice, while Pantoprazole acts only at pH not higher than 3.

The preparations contain various active and excipients, have their own characteristics of purpose, so the choice of Pantoprazole or Rabeprazole is made by the attending physician.

Pantoprazole or Nolpaza: which is better?

Under the name Pantoprazole, the drug is produced by Russian companies, and Nolpaza is an analogue of the Slovenian company KRKA. Pantoprazole and Nolpaza are complete analogues with the same active ingredient. They differ in manufacturers, excipients and the place of synthesis of substances. So, pantoprazole for Nolpaza is produced in Slovenia, and for Pantoprazole – in Spain and India.

According to the instructions for medical use, Nolpaza is approved for the treatment of children from 12 years of age. Therefore, the drug has an advantage in pediatric practice. In other cases, Nolpaza and Pantoprazole are interchangeable, taking into account the dosages prescribed by the doctor and the appointment.

Be aware that all proton pump inhibitors increase the risk of osteoporosis and certain gastrointestinal infections. If PPIs are prescribed, then other drugs that reduce the acidity of gastric juice should not be taken.
