Mechanism of Action
Itopride Hydrochloride works by:
- Increasing gastrointestinal motility by enhancing the release of acetylcholine at the neuromuscular junctions.
- Blocking dopamine receptors (D2 receptors) in the central nervous system, which reduces nausea and improves gastric emptying.
- Inhibiting acetylcholinesterase, thus prolonging the action of acetylcholine and promoting gastrointestinal motility.
How Long Does It Take to Work?
The onset of action for Itopride Hydrochloride is typically observed within 1 to 2 weeks of starting treatment. Some patients may notice symptomatic relief sooner, while the full therapeutic effect may take longer to achieve.
Absorption
Itopride Hydrochloride is well absorbed from the gastrointestinal tract after oral administration. Peak plasma concentrations are usually reached within 1 to 2 hours of dosing.
Route of Elimination
Itopride Hydrochloride is primarily metabolized in the liver. Its metabolites are excreted via the kidneys. About 80% of the dose is eliminated through the urine, and the remainder is excreted in the feces.
Dosage
The usual adult dose for oral use is 50 mg of Itopride Hydrochloride administered orally three times daily. The dose may be reduced according to the patient’s age and symptoms. Itopride Hydrochloride should be taken before meals.Use in the elderly: Since the elderly often have a physiological hypo function, they are prone to adverse reactions and should thus be closely monitored. If adverse reactions are evident, appropriate measures such as reduction or cessation of the drug should be implemented.
Use in pediatric population: The safety and efficacy of Itopride Hydrochloride in children and adolescents have not been established. Therefore, the administration of Itopride Hydrochloride is not recommended in children and adolescents below 18 years of age.

Hepatic function disorder and Jaundice: Hepatic function disorder and jaundice with increased AST(GOT), ALT(GPT) and g-GTP etc., may occur, and close observation should be made. If abnormalities occur, the drug should be discontinued and appropriate therapeutic measures implemented.
The typical dosage of Itopride Hydrochloride is:
- For adults: 50 mg to 150 mg taken orally, three times a day, 30 minutes before meals.

- Monitor for symptoms of extrapyramidal effects, especially in long-term use.
- Discontinue use if severe allergic reactions or significant side effects occur.
Interaction
Itopride Hydrochloride may interact with other medications, particularly those affecting gastrointestinal motility or central nervous system function. Consult with a healthcare provider to review potential drug interactions.
Disease Interaction
Patients with a history of Parkinson's disease or other movement disorders should use Itopride Hydrochloride with caution, as it may exacerbate symptoms. Regular monitoring is advised for those with liver or renal disease.
Drug Interaction
Interactions with drugs that affect the central nervous system, such as antipsychotics or antidepressants, may occur. Itopride Hydrochloride may also interact with other medications affecting gastrointestinal motility. Always inform healthcare providers of all medications being taken.
