5. CLOPAMON Injection Uses
CLOPAMON Injection works through multiple mechanisms, offering both gastrointestinal and anti-emetic benefits.
Pharmacodynamic Properties
Gastrointestinal Action
Metoclopramide stimulates the digestive tract by:
- Increasing the frequency and strength of antral (stomach) contractions
- Enhancing duodenal motility
- Accelerating gastric emptying
This action makes CLOPAMON useful in treating conditions involving delayed stomach emptying and gastrointestinal stasis.
Gastro-Oesophageal Junction
It increases pressure at the cardiac sphincter, helping to prevent acid reflux and regurgitation. This effect is more pronounced in individuals with normal resting sphincter pressure.
Effect of Anticholinergics
Anticholinergic medications like atropine can diminish the gastrointestinal effects of CLOPAMON if taken within three hours of administration.
Anti-Emetic Action
CLOPAMON works centrally by acting on the chemoreceptor trigger zone (CTZ) in the brain to suppress nausea and vomiting. This action remains effective even in the presence of anticholinergic medications.
Other Actions
Metoclopramide also stimulates prolactin secretion, which may lead to hormonal side effects in some users.
6. Indications
CLOPAMON Injection is used in the following clinical situations:
Digestive Disorders
- Post-vagotomy syndrome
- Conditions associated with delayed gastric emptying or hypomotility
Nausea and Vomiting
Effective in controlling nausea and vomiting caused by:
- Medications
- Kidney failure (uraemia)
- Cancer
- Gastrointestinal disorders
- Post-anaesthetic recovery
Diagnostic Radiology
Improves visualization during imaging studies by:
| Use Case | Purpose |
|---|---|
| Delayed barium meal studies | Reduces spasm in the duodenal cap |
| Hypotonic stomach (gastric stasis) | Enhances emptying and visual clarity |
| Preventing vomiting during barium exams | Reduces risk of emesis in sensitive patients |
Duodenal Intubation
Facilitates gastrointestinal procedures by:
- Promoting gastric emptying
- Reducing nausea and gag reflexes
7. Contraindications
CLOPAMON should not be used in the following conditions:
- Gastrointestinal bleeding, obstruction, or perforation
- Immediately post-operative GI surgery
- Phaeochromocytoma (risk of hypertensive crisis)
- Epilepsy (risk of seizures)
- Porphyria
Use is also discouraged in scenarios where increased gastrointestinal motility could be dangerous.
8. Warnings and Special Precautions
- Pregnancy: Safety is not established. Use only if absolutely necessary.
- Children and Elderly: Higher risk of extrapyramidal symptoms. Caution is advised.
- Renal or Hepatic Impairment: Risk of fluid retention and toxicity; monitor closely.
- Dilution Warning: Do not dilute ampoules as it affects isotonicity and drug stability.
- Long-Term Use: Requires regular medical review.
9. Interactions

CLOPAMON can interact with several medications:
| Interacting Substance | Effect |
|---|---|
| Phenothiazines | Increased risk of extrapyramidal reactions |
| Lithium | Increased toxicity |
| Antidepressants & antiepileptics | Caution due to central nervous system effects |
| Antimuscarinics & opioids | Reduce CLOPAMON’s GI effects |
| Digoxin | Reduced stomach absorption |
| Aspirin, Paracetamol | Increased small intestine absorption |
| Suxamethonium | Prolonged neuromuscular blockade |
| Bromocriptine | Reduced effectiveness due to raised prolactin levels |
10. Human Reproduction
- Pregnancy: Not established as safe.
- Use during pregnancy only when clearly needed and under professional guidance.
