Itoprid Pmcs (Itopride Hydrochloride)

Itopride Hydrochloride is a prokinetic that enhances gastrointestinal motility in several functional gastrointestinal disorders.

• Functional dyspepsia: alleviates upper abdominal discomfort and early satiety by accelerating gastric emptying.
• Gastroesophageal reflux disease: reduces reflux episodes by improving lower esophageal sphincter tone and gastric clearance.
• Gastric motility disorders: promotes coordinated stomach contractions to facilitate digestion and relieve stasis.

• Itopride Hydrochloride acts as a dopamine D2 receptor antagonist and an acetylcholinesterase inhibitor. By blocking D2 receptors in the gastrointestinal tract, it removes inhibitory dopaminergic tone, while inhibition of acetylcholinesterase increases acetylcholine availability. The combined effect enhances cholinergic stimulation of smooth‑muscle cells, leading to increased gastric motility, accelerated gastric emptying, and improved coordination of intestinal peristalsis. These actions collectively normalize delayed gastric transit associated with functional dyspepsia and reflux conditions.

Itopride Hydrochloride may be associated with a range of adverse reactions, varying from mild to serious.

Common Side Effects

• Nausea: mild stomach upset.
• Diarrhea: loose stools.
• Headache: transient head pain.

Serious or Rare Side Effects

• Extrapyramidal symptoms: involuntary muscle movements.
• Severe allergic reaction: rash, swelling, or anaphylaxis.
• Hepatic injury: elevated liver enzymes or jaundice.

When prescribing Itopride Hydrochloride, clinicians should consider several precautionary measures to ensure safe use.

• Assess renal function: adjust use in patients with severe renal impairment.
• Monitor hepatic status: avoid in individuals with significant liver disease.
• Observe for extrapyramidal effects: discontinue if involuntary movements appear.
• Avoid in known hypersensitivity: discontinue at first sign of allergic reaction.
• Store at room temperature: keep in the original container, protect from moisture and direct sunlight.

Itopride Hydrochloride can interact with other medicines, requiring attention to avoid reduced efficacy or increased toxicity.

Major Interactions (Avoid)

• Concurrent use with other prokinetic agents: may cause excessive gastrointestinal stimulation.
• Combination with strong anticholinergic drugs: can counteract the prokinetic effect.

Moderate Interactions (Monitor Closely)

• Co‑administration with CYP3A4 inhibitors: may increase plasma levels of Itopride.
• Use with antidiabetic medications: monitor blood glucose as gastrointestinal motility changes can affect absorption.
• Interaction with macrolide antibiotics: may alter gastric emptying and affect drug absorption.
