Ingredient-level reference
Itopride
Reference for: Itopride. Source presentation: IMMEDIATE-RELEASE TABLET. Source route: oral.
The cited studies use standard-release immediate-release tablet. The catalogue entry has a different or unspecified release description; these study values do not establish its absorption profile.
Mechanism of action
Itopride combines dopamine D2 receptor antagonism with acetylcholinesterase inhibition. Increased acetylcholine activity supports gastric motility and gastric emptying.
Pharmacokinetics
The immediate-release reference describes rapid gastrointestinal absorption, approximately 60% relative bioavailability and a peak 0.5–0.75 hours after 50 mg. Plasma protein binding is about 96%. Hepatic FMO3 metabolism forms an N-oxide; urinary recovery after the cited dose was 3.7% unchanged drug and 75.4% N-oxide. Terminal half-life is approximately 6 hours. Animal tissue-distribution findings are not human measurements, and these data do not establish sustained-release kinetics.
