Generic Metoclopramide Information

Introduction

Metoclopramide is a dopamine‑receptor antagonist that enhances gastrointestinal motility and exerts anti‑emetic effects. In Hong Kong it is prescribed for conditions such as diabetic gastroparesis, post‑operative nausea, and reflux‑related dyspepsia. The active compound is Metoclopramide, classified within the prokinetic drug group, and it is listed under the diabetes‑related medication category because of its role in managing gastroparesis secondary to diabetes mellitus. The drug was originally developed by Boehringer Ingelheim and is marketed worldwide under several brand names.

What is Metoclopramide?

Metoclopramide is the generic version of Reglan (also marketed as Primperan in some regions), containing the same active compound Metoclopramide. Our online pharmacy provides this generic alternative as a cost‑effective treatment option. It is a synthetic, white to off‑white, oral tablet or injectable solution that acts centrally on the chemoreceptor trigger zone and peripherally on the gastrointestinal smooth muscle.

• Classification: Prokinetic agent and anti‑emetic (dopamine D₂ receptor antagonist).
• Development: First synthesized in the 195s; approved for clinical use in the early 196s.
• Manufacturer: Originally launched by Boehringer Ingelheim; numerous licensed generic manufacturers now supply the drug worldwide.

How Metoclopramide Works

Metoclopramide blocks dopamine D₂ receptors in the chemoreceptor trigger zone of the medulla, reducing the brain’s nausea signaling. Peripherally, it antagonises D₂ receptors on the gastrointestinal tract and stimulates 5‑HT₄ receptors, leading to increased acetylcholine release. The net effect is:

• Accelerated gastric emptying – enhanced antral contractility and coordination of the pyloric sphincter.
• Increased lower‑esophageal sphincter tone – reduces reflux episodes.
• Anti‑emetic activity – diminishes the perception of nausea and vomiting.

Onset of action is typically within 30 minutes after oral intake, with a plasma half‑life of 5–6 hours. Renal excretion is the primary clearance pathway; impaired renal function prolongs exposure and may necessitate dose adjustment.

Conditions Treated with Metoclopramide

• Diabetic gastroparesis – delayed gastric emptying common in long‑standing diabetes; Metoclopramide improves gastric motility and symptom control.
• Post‑operative nausea and vomiting (PONV) – prophylactic or therapeutic use reduces incidence after surgery.
• Chemotherapy‑induced nausea – adjunctive therapy when standard anti‑emetics are insufficient.
• Reflux‑related dyspepsia – augmentation of lower‑esophageal sphincter tone eases heartburn and regurgitation.
• Functional dyspepsia – in selected cases where delayed gastric emptying is suspected.

In Hong Kong, the prevalence of diabetes exceeds 10 % of the adult population, and gastroparesis represents a notable source of morbidity. Metoclopramide offers a pharmacologic option when lifestyle measures and glucose control are inadequate.

Who is Metoclopramide For?

• Adults with diabetic gastroparesis who experience early satiety, nausea, or bloating despite optimal glycaemic control.
• Patients undergoing surgery or receiving emetogenic chemotherapy, requiring short‑term anti‑emetic support.
• Individuals with chronic reflux not responding fully to proton‑pump inhibitors alone.

Contra‑indications include hypersensitivity to Metoclopramide, mechanical obstruction of the gastrointestinal tract, and severe central nervous system disorders such as Parkinson’s disease. Caution is advised in patients with renal insufficiency, epilepsy, or a history of depressive disorders, as the drug may exacerbate central side effects.

Risks, Side Effects, and Interactions

Common

• Drowsiness or mild fatigue.
• Restlessness (akathisia).
• Dry mouth.
• Diarrhoea or loose stools.

Rare

• Extrapyramidal symptoms (e.g., tremor, dystonia).
• Elevated prolactin levels leading to galactorrhoea or menstrual irregularities.
• Mood changes, including anxiety or depression.

Serious

• Neuroleptic malignant syndrome – rare but potentially life‑ threatening; characterised by hyperthermia, rigidity, autonomic instability.
• Tardive dyskinesia – irreversible involuntary movements, risk increases with cumulative exposure beyond 12 weeks.
• Severe allergic reactions (anaphylaxis), manifested by rash, swelling, or bronchospasm.

Drug–Drug Interactions

• Concomitant use of anticholinergic agents (e.g., atropine) may diminish prokinetic efficacy.
• CYP2D6 inhibitors (e.g., fluoxetine, quinidine) can increase plasma Metoclopramide concentrations.
• Co‑administration with other dopamine antagonists (e.g., antipsychotics) heightens the risk of extrapyramidal reactions.
• High‑dose opioids may potentiate sedation; monitor patients closely.

Patients should disclose all current medications, including over‑the‑counter products and herbal supplements, to their healthcare provider before initiating Metoclopramide.

Practical Use: Dosing, Missed Dose, Overdose

• Standard oral dosing for diabetic gastroparesis: 10 mg before meals and at bedtime (total 30 mg per day). For acute nausea, 10–20 mg every 6–8 hours as needed, not exceeding 40 mg daily.
• Intravenous administration (hospital setting) typically 10 mg over 1–2 minutes, repeatable every 6 hours under monitoring.
• Missed dose: Take the missed dose as soon as remembered if at least 6 hours remain before the next scheduled dose; otherwise skip and resume regular schedule. Do not double the dose.
• Overdose: Symptoms may include profound sedation, seizures, or severe extrapyramidal signs. Immediate medical attention is required; treatment is supportive, with possible use of benzodiazepines for seizure control.
• Precautions:
  • Take with a small amount of food to reduce gastrointestinal irritation.
  • Avoid alcohol, which may intensify sedation.
  • Patients with severe renal impairment should start with a reduced dose (e.g., 5 mg) and be monitored for accumulation.

FAQ

• Is Metoclopramide available in both brand‑name and generic forms in Hong Kong?
  Yes. The drug is marketed under brand names such as Reglan and Primperan, while generic versions containing the same active compound are also approved and widely distributed.

• Does Metoclopramide require cold storage?
  No. Metoclopramide tablets and oral solutions should be stored at controlled room temperature (15 °C–30 °C), protected from moisture and direct sunlight.

• What packaging does Metoclopramide come in when ordered online?
  Typically, Metoclopramide is supplied in amber‑colored blister packs of 10 mg tablets, with each tablet numbered for easy identification. Bulk powder for injection is packaged in sealed glass vials.

• Can Metoclopramide be safely imported into Hong Kong for personal use?
  Personal import of a three‑month supply for non‑commercial use is permitted under Hong Kong’s import regulations, provided the product is accompanied by a valid prescription and conforms to the local Pharmaceutical Registration standards.

• Are there manufacturer warnings specific to Asian populations?
  Clinical data indicate that East Asian patients may exhibit a slightly higher incidence of extrapyramidal symptoms; therefore, clinicians often limit therapy duration and monitor neurological status closely.

• Does the formulation of Metoclopramide differ between regions (e.g., US vs. EU vs. Asia)?
  The core active ingredient is identical across regions, but excipient profiles may vary. For example, Asian formulations frequently use lactose‑free binders to accommodate prevalent lactose intolerance.

• How does Metoclopramide compare to newer prokinetics such as prucalopride?
  Metoclopramide has a broader anti‑emetic profile but a higher risk of central nervous system side effects. Prucalopride is more selective for 5‑HT₄ receptors, offering a better safety margin for chronic use but lacking strong anti‑emetic efficacy.

• What is the historical significance of Metoclopramide in gastroenterology?
  Introduced in the 196s, Metoclopramide became the first dopamine antagonist approved for enhancing gastric motility, establishing the therapeutic class of prokinetics and shaping modern management of gastroparesis.

• Can Metoclopramide affect drug testing for employment or sports?
  Metoclopramide is not listed among prohibited substances by major anti‑doping agencies and generally does not trigger false‑positive results in standard employment drug screens.

• What should travelers know about carrying Metoclopramide across borders?
  Carry the medication in its original packaging with a copy of the prescription. Declare it at customs if required, and ensure the quantity does not exceed the personal use limit established by the destination country.
