Merin
Merin Uses, Dosage, Side Effects, Food Interaction and all others data.
Merin is dopamine receptor (D2) antagonist which selectively inhibits dopamine at the D2 receptor. It acts principally at receptors in the chemoreceptor trigger zone (CTZ) and also at receptors in the stomach.
Merin is a specific blocker of dopamine receptors. It speeds gastrointestinal peristalsis, causes prolactin release, and is used as antiemetic and tool in the study of dopaminergic mechanisms.

How Merin works
Merin acts as a gastrointestinal emptying (delayed) adjunct and peristaltic stimulant. The gastroprokinetic properties of domperidone are related to its peripheral dopamine receptor blocking properties. Merin facilitates gastric emptying and decreases small bowel transit time by increasing esophageal and gastric peristalsis and by lowering esophageal sphincter pressure. Antiemetic: The antiemetic properties of domperidone are related to its dopamine receptor blocking activity at both the chemoreceptor trigger zone and at the gastric level. It has strong affinities for the D2 and D3 dopamine receptors, which are found in the chemoreceptor trigger zone, located just outside the blood brain barrier, which - among others - regulates nausea and vomiting
Dosage
Merin dosage
Adults: 10 - 20 mg every 4 - 8 hours daily
Children: 0.2 - 0.4 mg/kg every 4 - 8 hours daily.
Merin tablet and suspension should be taken 15 - 30 minutes before a meal. For acute nausea and vomiting, maximum period of treatment is 12 weeks.
Side Effects
Merin may produce hyperprolactinemia which may cause galactorrhea & breast enlargement, soreness and reduced libido. It may rarely cause dry mouth, thirst, headache, nervousness, drowsiness, diarrhea, skin rash and itching.
Toxicity
Side effects include galactorrhea, gynecomastia, or menstrual irregularities.
Precaution
Merin should be used with absolute caution in case of children because there may be an increased risk of extra-pyramidal reactions in young children because of an incompletely developed blood brain barrier.
Interaction
Merin may reduce the hypoprolactinaemic effect of bromocriptine. Anti-muscarinics and opioid analgesics may antagonize the action of Merin on gastrointestinal function.
Food Interaction
- Take before a meal. Take 15-30 minutes before meals.
Half Life
7 hours
Pregnancy & Breastfeeding use
Use in pregnancy: The safety of this drug has not been established for pregnant women. So it is not recommended during pregnancy.
Use in lactation: Merin may precipitate galactorrhea and improve postnatal lactation, which is secreted in breast milk but in very small quantities insufficient to be considered harmful.
Contraindication
Merin is contraindicated to the patients who have hypersensitivity to this drug and in case of neonates.
Acute Overdose
Overdose has been reported primarily in infants and children. Symptoms of overdosage may include disorientation, somnolence and extrapyramidal reactions. There is no specific antidote to domperidone, but in the event of overdose, the administration of activated charcoal may be useful. Anticholinergics, antiparkinson drugs may be useful in controlling extrapyramidal reactions. The patient should be observed closely and supportive measures employed.
Storage Condition
Store in a cool dry place protected from light. Keep out of reach of children.
