Clinical-Pharmacological Group

H⁺-K⁺-ATPase inhibitor. Antiulcer drug

Pharmacotherapeutic Group

Gastric secretion reducing agent – proton pump inhibitor

Pharmacological Action

H⁺-K⁺-ATPase inhibitor. It blocks the final stage of hydrochloric acid secretion, reducing the level of basal and stimulated (regardless of the type of stimulus) hydrochloric acid secretion in the stomach.

In Helicobacter pylori-associated duodenal ulcer disease, such a reduction in gastric secretion increases the sensitivity of the microorganism to antibiotics.

Pantoprazole has its own antimicrobial activity against Helicobacter pylori.

Pharmacokinetics

Pantoprazole is rapidly absorbed after oral administration. C_max after the first 20 mg dose is about 1.0-1.5 µg/ml.

The pharmacokinetics of pantoprazole after single and multiple administration are the same. In the dose range of 10-80 mg, the pharmacokinetics of pantoprazole in plasma remain linear for both oral and intravenous administration.

The absolute bioavailability of pantoprazole after oral administration is about 77%. Plasma protein binding is 98%. V_d is 0.15 l/kg.

It is metabolized mainly in the liver. The main metabolic pathway is demethylation by CYP2C19 followed by sulfate conjugation. Other metabolic pathways include oxidation by CYP3A4.

The terminal T_1/2 is approximately 1 hour, clearance is about 0.1 l/h/kg.

The main route of excretion is through the kidneys (about 80%) in the form of pantoprazole metabolites, the rest is excreted in the feces.

Indications

Peptic ulcer of the stomach and duodenum in the acute phase, erosive gastritis (including that associated with NSAID use), stress ulcers and their complications (bleeding, perforation, penetration); Zollinger-Ellison syndrome; eradication of Helicobacter pylori (in combination with antibacterial therapy); gastroesophageal reflux disease; erosive reflux esophagitis.

ICD codes

Dosage Regimen

Take one 40 mg tablet once daily with a glass of water before a meal, preferably in the morning.

Swallow tablets whole; do not crush or chew.

For duodenal ulcer and gastric ulcer, the usual treatment duration is 2 to 4 weeks; for severe or recurrent cases, extend to 8 weeks.

For erosive reflux esophagitis, the initial course is 4 to 8 weeks; for long-term management, use the lowest effective dose.

For Helicobacter pylori eradication, use a 7 to 14 day regimen combining pantoprazole 40 mg twice daily with two appropriate antibiotics as prescribed.

In Zollinger-Ellison syndrome, the initial dose is 80 mg once daily; adjust the dose individually based on gastric acid output, with a maximum daily dose of 240 mg divided into two administrations.

For patients with severe liver impairment, do not exceed a daily dose of 20 mg.

For patients with renal impairment and elderly patients, do not exceed the standard 40 mg daily dose; dosage adjustment is not typically required.

The total duration of therapy should not exceed 8 weeks without reassessment; for maintenance therapy, use the minimum effective dose.

Contraindications

Hypersensitivity to pantoprazole; neurotic dyspepsia, malignant diseases of the gastrointestinal tract, severe hepatic insufficiency; pregnancy, lactation (breastfeeding); childhood; use of HIV protease inhibitors such as atazanavir and nelfinavir, the absorption of which depends on the pH of gastric juice (for oral administration).

With caution hepatic insufficiency.

Use in Pregnancy and Lactation

Contraindicated for use during pregnancy and lactation (breastfeeding).

If use during lactation is necessary, the issue of discontinuing breastfeeding should be considered.

Use in Hepatic Impairment

Contraindicated for use in severe hepatic insufficiency. When used in patients with impaired liver function, plasma liver enzyme activity should be regularly monitored and Pantoprazole should be discontinued if it increases.

Use in Renal Impairment

In case of impaired renal function, it is not recommended to exceed the dose of 40 mg/day.

Pediatric Use

Contraindicated for use in children and adolescents under 18 years of age.

Geriatric Use

Proton pump inhibitors, especially when used in high doses and for a long time (more than 1 year), may moderately increase the risk of fractures of the femur, wrist and spine, mainly in the elderly. In elderly patients, it is not recommended to exceed the dose of 40 mg/day.

Special Precautions

Intravenous use of pantoprazole is recommended only if oral administration is not possible.

Before starting therapy, the possibility of a malignant neoplasm in the stomach and esophagus should be excluded, because the use of pantoprazole reduces the severity of symptoms and may delay the establishment of the correct diagnosis. The diagnosis of reflux esophagitis requires mandatory endoscopic confirmation.

In elderly patients and in case of impaired renal function, it is not recommended to exceed the dose of 40 mg/day.

When used in patients with impaired liver function, plasma liver enzyme activity should be regularly monitored and Pantoprazole should be discontinued if it increases.

Proton pump inhibitors, especially when used in high doses and for a long time (more than 1 year), may moderately increase the risk of fractures of the femur, wrist and spine, mainly in the elderly or in the presence of other risk factors.

Effect on the ability to drive vehicles and mechanisms

During the use of pantoprazole, patients should be cautious when driving vehicles and mechanisms, as well as when engaging in other potentially hazardous activities that require increased concentration and speed of psychomotor reactions.

Drug Interactions

With simultaneous use, Pantoprazole may change the absorption of drugs whose absorption depends on the pH of the gastric contents (for example, ketoconazole, itraconazole, posaconazole and other drugs such as erlotinib).

Concomitant use of pantoprazole and HIV protease inhibitors, the absorption of which depends on the acidity (pH) of gastric juice, such as atazanavir, nelfinavir, significantly reduces their bioavailability.

Since Pantoprazole is metabolized in the liver by the cytochrome P450 enzyme system, the possibility of drug interaction with drugs metabolized by the same enzyme system cannot be excluded.
