PHARMACOLOGICAL PROPERTIES

Mechanism of Action: GASTORELIVE (Itopride hydrochloride) activates gastrointestinal propulsive motility due to its dopamine D2 antagonizing activity and acetylcholinesterase inhibitory activity. Itopride activates acetylcholine release and inhibits its degradation.

Pharmacodynamics: GASTORELIVE (Itopride hydrochloride) also has antiemetic action through interaction with D2 receptors located in the chemoreceptor trigger zone.

GASTORELIVE (Itopride hydrochloride) has been shown to accelerate gastric emptying in humans. The action of GASTORELIVE is highly specific for the upper gastrointestinal tract. GASTORELIVE does not affect serum gastrin levels.

Pharmacokinetic Properties

Absorption: GASTORELIVE (Itopride hydrochloride) is rapidly and almost completely absorbed from the gastrointestinal tract. Relative bioavailability is calculated to be 60% due to liver first pass metabolism, there is no effect of food on bioavailability. Peak plasma levels (Cmax 0.28 microgram/mL) are reached after 0.5 to 0.75 hours after 50 mg of itopride hydrochloride.

Following multiple oral doses ranging from 50 mg to 200 mg tid, itopride hydrochloride and its metabolites showed linear pharmacokinetics over a treatment period of seven days. with minimal accumulation.

Distribution: Approximately 96% of GASTORELIVE (Itopride hydrochloride) is bound to plasma proteins. Albumin accounts for most of the binding. Alpha-1-acid-glycoprotein accounts for less than 15% of binding.

Distribution Approximately 96% of GASTORELIVE (Itopride hydrochloride) is bound to plasma proteins. Albumin accounts for most of the binding. Alpha-1 -acid – glycoprotein accounts for less than 15% of binding.

Metabolism: GASTORELIVE (Itopride hydrochloride) undergoes extensive hepatic metabolism in humans. Three (3) metabolites have been identified, of which only one exerts minor activity without pharmacological relevance (approximately 2-3% of that of itopride).

The primary metabolite in humans is the N-oxide, generated by oxidation of the tertiary amine N-dimethyl group. GASTORELIVE is metabolized by a flavin-dependent mono-oxygenase (FMO3). The abundance and efficiency of the human FMO- isozymes can be subject to genetic polymorphisms, which can lead to a rare autosomal recessive condition known as trimethylaminuria (fish odor syndrome).

The half-life of GASTORELIVE may therefore be longer in trimethylaminuria patients. In vivo pharmacokinetic studies on CYP- mediated reactions revealed that GASTORELIVE showed neither inhibitory nor inductory effect on CYP2C19 and CYP2E1. CYP content and uridine diphosphate glucuronosyl transferase activity were not altered with the administration of itopride.

Excretion: GASTORELIVE (Itopride hydrochloride) and its metabolites are primarily excreted in the urine. The urinary excretions of GASTORELIVE and its N-oxide were 3.7% and 75.4%, respectively, in healthy subjects after oral administration of a single therapeutic dose. The terminal phase half-life of GASTORELIVE was approximately six (6) hours.

CONTRAINDICATIONS

GASTORELIVE (Itopride hydrochloride) is contraindicated in patients with known hypersensitivity to itopride hydrochloride or any of the excipients. GASTORELIVE should not be used in patients in whom an increase in gastrointestinal motility could be harmful, e.g., gastrointestinal hemorrhage, mechanical obstruction or perforation.

PRECAUTIONS

General: GASTORELIVE (Itopride hydrochloride) enhances the action of acetylcholine and may produce cholinergic side effects.

DRUG INTERACTIONS

Metabolic interactions are not expected since GASTORELIVE (Itopride hydrochloride) is primarily metabolized by flavine monooxygenase and not by CYP450. No changes in protein binding have been seen with coadministration of warfarin, diazepam, diclofenac sodium, ticlopidine hydrochloride, nifedipine, and nicardipine hydrochloride.

Since GASTORELIVE has gastrokinetic effects it could influence the absorption of concomitantly orally administered drugs. Particular caution should be taken with drugs with a narrow therapeutic index, sustained release or enteric-coated formulations.

Anti-ulcer drugs like cimetidine, ranitidine, teprenone and cetraxate do not alter the prokinetic action of itopride, Anticholinergic drugs may reduce the action of GASTORELIVE.

PREGNANCY & LACTATION

There are no adequate and well-controlled studies in pregnant women. Therefore, GASTORELIVE (Itopride hydrochloride) should not be used during pregnancy unless the benefits outweigh the potential risks. There are no known effects of GASTORELIVE on labor or delivery.

Because GASTORELIVE is excreted in milk, and because of the potential for adverse reactions in nursing infants, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.

PEDIATRIC USE

Safety of this product in children under the age of 16 has not been established.

GERIATRIC USE

In general, appropriate caution should be exercised in the administration and monitoring of GASTORELIVE (Itopride hydrochloride) in elderly patients reflecting the greater frequency of decreased hepatic, renal function, and of concomitant disease or other drug therapy.

ADVERSE REACTIONS

The following adverse events have been reported in patients receiving GASTORELIVE (Itopride hydrochloride).

  • Blood and lymphatic system disorders: Leukopenia and thrombocytopenia.
  • Immune system disorders: Anaphylactoid reaction.
  • Endocrine disorders: Increased prolactin level and gynecomastia.
  • Nervous system disorders: Dizziness, headache and tremor.
  • Gastrointestinal disorders: Diarrhea, constipation, abdominal pain, increased saliva and nausea.
  • Hepato-biliary disorders:
  • Skin and subcutaneous tissue disorders: Rash, redness, and itching.
  • Investigations: Increased AST (SGOT), increased ALT (SGPT), increased gamma -GTP, increased alkaline phosphatase, and increased bilirubin.

OVER DOSAGE

There have been no reported cases of overdose in humans. In of overdose the usual measures of gastric lavage and symptomatic therapy should be applied.

STORAGE

  • Store between 15 °C – 30 °C
  • Do not use beyond the expiration date.
