How to Administer Tab. Ganaton 50 (Itopride)

Administer itopride 50 mg orally three times daily, taken before meals, for the treatment of functional dyspepsia and related upper gastrointestinal symptoms. 1, 2

Standard Dosing Regimen

• Dose: 50 mg (one tablet) three times daily 1, 2, 3
• Timing: Take before meals 1, 2
• Duration: Typically prescribed for 4-8 weeks 1, 2
• Route: Oral administration only 1, 2, 3

Treatment Duration and Response Timeline

• Week 1: Approximately 34-36% of patients show treatment response 1
• Week 2: Response rate increases to 53-55% 1
• Week 4: Response rate reaches 73-75% 1
• Week 8: Maximum therapeutic effect achieved with 86% response rate 2

The therapeutic effect is sustained even 4 weeks after discontinuation, with 82% of patients maintaining improvement 2.

Dose Adjustment Considerations

While the standard dose is 50 mg three times daily, studies have evaluated higher doses:

• 150 mg daily (50 mg three times daily): Standard effective dose 4
• 300 mg daily (100 mg three times daily): More effective for reducing esophageal acid exposure in GERD patients, though this is off-label use 4

For functional dyspepsia, the 50 mg three times daily regimen provides optimal efficacy with excellent tolerability 1, 2, 3.

Safety Monitoring

• Adverse events: Very low incidence (1.5-3.1% in clinical studies) 1, 2
• ECG monitoring: Baseline ECG recommended; itopride does not prolong QT interval 3
• Laboratory tests: Baseline and follow-up liver and renal function tests are prudent, though abnormalities are rare 2, 3
• Prolactin levels: No elevation observed with itopride, unlike other prokinetics 3

Important Clinical Pearls

Common pitfall: Unlike some prokinetics that require dosing after meals, itopride must be taken before meals to optimize its prokinetic effect on gastric emptying 1, 2.

The drug is well-tolerated with minimal serious adverse events, and no dose adjustments are typically needed for mild-to-moderate hepatic or renal impairment based on the safety data from large observational studies 1, 2.

When to Reassess

• Evaluate symptom improvement at 2 weeks to determine if continuation is warranted 1
• If no response by 4 weeks, consider alternative diagnoses or therapies 1, 2
• Maximum benefit typically achieved by 8 weeks of continuous therapy 2
