Usage
Itopride + Pantoprazole is prescribed for the management of gastrointestinal disorders, primarily gastroesophageal reflux disease (GERD) and dyspepsia, particularly when monotherapy with either drug is insufficient. It is also beneficial in conditions like peptic ulcer disease, functional dyspepsia, and gastric motility disorders. This combination medication falls under the pharmacological classifications of prokinetic agents (itopride) and proton pump inhibitors (pantoprazole).
Itopride enhances gastric motility by inhibiting acetylcholinesterase, increasing acetylcholine concentrations, and promoting faster movement of food through the stomach. Pantoprazole reduces gastric acid production by irreversibly binding to and inhibiting the hydrogen-potassium ATPase enzyme system (proton pump) in parietal cells.
Alternate Names
There is no internationally recognized non-proprietary name for the combination. It is often referred to simply as Itopride + Pantoprazole or as Pantoprazole + Itopride. Brand names include Pantostrum IT and Pantop IT.
How It Works
Pharmacodynamics: Itopride, a prokinetic agent, increases the movement of the stomach and intestines, improving gastric emptying. Pantoprazole, a proton pump inhibitor, decreases gastric acid secretion. The combination addresses both the motility and acid production aspects of GERD and dyspepsia.
Pharmacokinetics: Pantoprazole is rapidly absorbed after oral administration, metabolized by the liver (CYP450 system, primarily CYP2C19), and excreted mainly through the kidneys. Itopride is also readily absorbed, metabolized by flavin monooxygenase, and primarily eliminated renally. Both medications reach peak plasma concentrations within a few hours.
Mode of Action: Itopride enhances acetylcholine activity in the digestive tract, stimulating motility. Pantoprazole irreversibly binds to H+/K+ ATPase, the proton pump, in gastric parietal cells, thereby blocking acid secretion.
Receptor Binding, Enzyme Inhibition or Neurotransmitter Modulation: Itopride inhibits acetylcholinesterase and dopamine D2 receptors. Pantoprazole inhibits the H+/K+ ATPase enzyme.
Elimination Pathways: Both Itopride and Pantoprazole are primarily eliminated via renal excretion, with hepatic metabolism also contributing.
Dosage
Standard Dosage
Adults:
The usual dose is one capsule containing 40 mg pantoprazole and 150 mg itopride, taken orally once daily before a meal, typically before breakfast. This strength may vary based on patient response or product availability (e.g., some strengths have 150mg of Itopride, while others may offer 50mg. The timing is dependent on the brand and formulation). Treatment duration can vary depending on the condition but can extend up to 8 weeks. Always consult product specifics or a healthcare provider to determine the appropriate dosing regimen.
Children: The safety and efficacy of Itopride + Pantoprazole have not been established in children under 12 years. Use in children is generally not recommended. Pantoprazole alone can be used to treat children 5 years and older based on weight.
Special Cases:
-
Elderly Patients: Dose adjustments may be necessary based on renal and hepatic function.
-
Patients with Renal Impairment: Caution and dose adjustments may be required depending on the degree of impairment.
-
Patients with Hepatic Dysfunction: Dose adjustments are usually necessary for patients with moderate to severe hepatic impairment.
-
Patients with Comorbid Conditions: Careful consideration is needed for patients with conditions such as osteoporosis, hypomagnesemia, or a history of cardiac arrhythmias.
Clinical Use Cases
Dosage in clinical settings like intubation, surgical procedures, mechanical ventilation, ICU, and emergency situations typically involves administering Pantoprazole alone intravenously, not the combination. Refer to Pantoprazole dosing guidelines for these scenarios.
Dosage Adjustments
Dose modifications are based on individual patient factors such as renal or hepatic impairment and response to therapy. Therapeutic drug monitoring may be beneficial.
Side Effects
Common Side Effects: Headache, diarrhea, nausea, stomach pain, dizziness, dry mouth, constipation, flatulence.
Rare but Serious Side Effects: Severe allergic reactions (anaphylaxis, angioedema), gynecomastia (breast swelling in males), QT prolongation, severe skin rash, hypomagnesemia (low magnesium), vitamin B12 deficiency.
Long-Term Effects: Osteoporosis (weak bones) with prolonged use, especially at higher doses.
Adverse Drug Reactions (ADR): Gynecomastia, severe skin reactions (Stevens-Johnson syndrome), hepatotoxicity, pancreatitis.
Contraindications
-
Hypersensitivity: Known allergy to itopride or pantoprazole.
-
Gastrointestinal Conditions: Gastrointestinal bleeding, mechanical obstruction, perforation.
-
Other Conditions: Gastric cancer, severe liver disease, osteoporosis.
-
Concomitant Medications: Avoid with drugs metabolized by CYP450 (especially CYP2C19), those requiring an acidic environment for absorption, other prokinetics, or anticholinergic drugs.
Drug Interactions
Itopride + Pantoprazole can interact with various medications, including warfarin, diazepam, phenytoin, ketoconazole, itraconazole, digoxin, metoclopramide, and anticholinergic drugs. Consult a comprehensive drug interaction resource for specific details. It is also not advisable to consume alcohol while taking Itopride + Pantoprazole.
Pregnancy and Breastfeeding
The safety of Itopride + Pantoprazole during pregnancy and breastfeeding has not been definitively established. Use only if the potential benefits outweigh the risks and under close medical supervision. Itopride is known to be excreted in breast milk, potentially affecting nursing infants. Pantoprazole is known to enter breast milk, with unknown effects on nursing infants.

Q1: What is the recommended dosage for Itopride + Pantoprazole?
A: The typical adult dose is one capsule containing 40 mg of pantoprazole and 150 mg of itopride taken orally once daily before a meal. Dose adjustments might be needed based on individual patient factors. Always check the specific brand/formulation you are using, as this can change.
Q2: How does Itopride + Pantoprazole work?
A: Itopride improves gastric motility, while pantoprazole reduces stomach acid production. This dual action effectively manages GERD and dyspepsia.
