Generic Domperidone Information

Introduction

Domperidone is a prescription medication classified under the Gastro Health group. It is routinely used in Hong Kong to relieve nausea, vomiting, and symptoms of delayed gastric emptying. The active compound, Domperidone, acts on the gastrointestinal tract to improve motility and reduce the sensation of nausea. In addition to its primary gastrointestinal indications, clinicians may prescribe Domperidone off‑label for certain prolactin‑related disorders when other therapies are unsuitable.

What is Domperidone?

Domperidone is a synthetic benzamide derivative that functions as a peripheral dopamine‑2 (D₂) receptor antagonist. It was first synthesized in the 197s by Janssen Pharmaceutica and marketed globally under several brand names, the most widely recognized being Motilium.

Domperidone is the generic version of Motilium, containing the same active compound Domperidone. Our online pharmacy provides this generic alternative as a cost‑effective treatment option.

In Hong Kong, Domperidone is supplied by licensed local distributors and by overseas pharmacies that work with Hong Kong‑registered pharmacists to ensure regulatory compliance.

How Domperidone Works

Domperidone blocks D₂ receptors located on the chemoreceptor trigger zone of the medulla and on enteric smooth‑muscle cells of the stomach and small intestine. By antagonising dopamine, it removes the inhibitory influence on acetylcholine release, thereby enhancing the coordinated contractions of the gastrointestinal (GI) tract. The resulting increase in gastric emptying and intestinal transit alleviates nausea and reduces the risk of reflux.

Key pharmacokinetic points:

• Onset of action: 30–60 minutes after oral administration.
• Peak plasma concentration: Approximately 1–2 hours.
• Elimination half‑life: 7–9 hours in healthy adults; prolonged in renal impairment.
• Metabolism: Primarily hepatic via CYP3A4; minor renal excretion.

Because Domperidone does not readily cross the blood‑brain barrier, it produces fewer central nervous system (CNS) side effects compared with older dopamine antagonists such as metoclopramide.

Conditions Treated with Domperidone

• Nausea and vomiting of unknown origin – often associated with early‑stage pregnancy, chemotherapy, or postoperative states.
• Gastroparesis – delayed gastric emptying documented by gastric scintigraphy, commonly seen in diabetic patients.
• Functional dyspepsia – epigastric discomfort linked to impaired gastric motility.
• Reflux‑related symptoms – when acid‑suppressive therapy alone is insufficient.
• Prolactin‑mediated disorders (off‑label) – such as hyperprolactinemia causing galactorrhoea or menstrual irregularities, when other dopamine antagonists are contraindicated.

In Hong Kong, gastroparesis prevalence is estimated at .5 % of the adult population, with higher rates among patients with long‑standing diabetes mellitus. Nausea‑related presentations account for a sizable proportion of emergency department visits, underscoring the clinical relevance of an accessible anti‑emetic like Domperidone.

Patient Groups Most Likely to Benefit

• Adults with diabetic gastroparesis – improved gastric emptying translates into better glycaemic control.
• Patients undergoing chemotherapy – adjunctive anti‑emetic therapy reduces treatment discontinuation.
• Individuals with functional dyspepsia unresponsive to proton‑pump inhibitors – motility enhancement addresses underlying pathophysiology.
• Women with lactation‑related hyperprolactinemia – off‑label use may normalize prolactin where other agents are unsuitable.

Domperidone is generally not appropriate for:

• Patients with known cardiac conduction abnormalities (e.g., prolonged QT interval).
• Those taking strong CYP3A4 inhibitors (e.g., clarithromycin, ketoconazole) without cardiology oversight.
• Children under 12 years unless specifically prescribed by a pediatric gastroenterologist.

Renal or hepatic impairment may require dose adjustment and careful monitoring.

Risks, Side Effects, and Interactions

Common

• Dry mouth – transient, often mild.
• Headache – usually resolves within a few days.
• **Abdominal cramps – related to increased GI motility.

Rare

• Elevated serum prolactin – may cause menstrual changes or galactorrhoea.
• Cardiac arrhythmia (QT prolongation) – observed in patients with pre‑existing risk factors or high plasma concentrations.

Serious

• Torsades de pointes – a life‑threatening ventricular tachyarrhythmia; risk amplified by concomitant QT‑prolonging drugs or electrolyte disturbances.
• Severe allergic reactions – anaphylaxis, angioedema; require immediate emergency care.

Clinically Relevant Interactions

• CYP3A4 inhibitors (e.g., erythromycin, ciprofloxacin, azole antifungals) – increase Domperidone plasma levels, heightening cardiac risk.
• Other QT‑prolonging agents (e.g., fluoroquinolones, antiarrhythmics, certain antipsychotics) – additive effect on QT interval.
• Anticholinergic drugs – may blunt the pro‑kinetic effect.

Patients should disclose all prescription, over‑the‑counter, and herbal products before initiating therapy.

Practical Use: Dosing, Missed Dose, Overdose

• Standard adult dosing for nausea: 10 mg orally three to four times daily, taken 30 minutes before meals.
• Gastroparesis dosing: 20 mg three times daily, with the same timing recommendation.
• Maximum daily dose: 80 mg (i.e., four 10 mg tablets) unless directed otherwise by a specialist.

Missed dose: Take the missed tablet as soon as it is remembered, provided that at least 4 hours remain before the next scheduled dose. Do not double the dose to compensate.

Overdose: Symptoms may include severe dizziness, fainting, or cardiac palpitations. Seek emergency medical attention promptly; supportive care and cardiac monitoring are the mainstays of management.

Precautions:

• Avoid alcohol, which can exacerbate dizziness.
• Do not take with high‑fat meals, as they may delay absorption.
• Patients with renal insufficiency should have dosing reduced to 10 mg three times daily.
• Routine ECG monitoring is advised for patients on long‑term therapy or those with cardiovascular risk factors.

FAQ

• Is Domperidone covered by the Hong Kong Department of Health’s drug subsidy scheme?
  No, Domperidone is not listed under the public drug subsidy scheme, so patients usually pay out‑of‑pocket or use private insurance. Purchasing from our online pharmacy can lower the overall expense.

• Can Domperidone be used while breastfeeding?
  Small amounts of Domperidone pass into breast milk, but studies suggest the exposure is minimal. Nevertheless, use should be under medical guidance, especially if the infant shows signs of jitteriness or poor feeding.

• What distinguishes Domperidone tablets from suspensions?
  Tablets contain the active ingredient in a solid form, offering stable dosing and longer shelf life. Suspensions are liquid formulations used for patients who have difficulty swallowing tablets, but they may require refrigeration and have a shorter expiry.

• Are there any dietary restrictions while taking Domperidone?
  High‑fat meals can delay absorption, potentially reducing efficacy. It is advisable to take the medication 30 minutes before meals and avoid consuming large fatty foods immediately afterward.

• How long does it take to see symptom improvement in gastroparesis?
  Clinical trials show measurable improvements in gastric emptying within 1–2 weeks, with symptom relief often reported after 2–4 weeks of consistent dosing.

• Does Domperidone interact with traditional Chinese medicines commonly used in Hong Kong?
  Some herbal products (e.g., St. John’s wort) are known CYP3A4 inducers and could lower Domperidone levels, while others may contain QT‑prolonging constituents. Patients should discuss any herbal supplementation with their prescriber.

• Can I travel internationally with Domperidone purchased online?
  Yes, provided you carry a valid prescription and the medication is in its original packaging. Some countries require a personal import permit; our pharmacy can supply the necessary documentation upon request.

• What is the recommended storage condition for Domperidone tablets?
  Store at room temperature (15 °C–30 °C), away from direct sunlight, moisture, and heat sources. Keep the container tightly closed and out of reach of children.

• Is it safe to combine Domperidone with over‑the‑counter anti‑emetics like meclizine?
  Combining two anti‑emetics can increase efficacy but may also heighten the risk of side effects such as dizziness. Concomitant use should be prescribed and monitored by a healthcare professional.

• Why does Domperidone sometimes cause breast milk production?
  By antagonising dopamine, Domperidone removes dopamine’s inhibitory effect on prolactin secretion from the pituitary gland, leading to elevated prolactin levels that stimulate lactation. This effect is intentional in certain off‑label uses for lactation induction.
