Description
Overview of the medicine
Domperidone is an antiemetic and prokinetic agent used to relieve nausea and vomiting and treat gastric motility disorders. This 5 mg/5 ml suspension is often used in pediatric populations or for adults who have difficulty swallowing tablets.
Uses & Indications
Dosage
Adults
Adults: 10-20 mg (2-4 teaspoons of 5 mg/5 ml suspension) up to 3 times daily, 15-30 minutes before meals. Maximum 30 mg/day. Children (older than 1 month and weighing less than 35 kg): 0.25-0.5 mg/kg body weight (e.g., a 10 kg child would take 2.5-5 ml of suspension per dose), up to 3 times daily, 15-30 minutes before meals. Maximum 10 mg/day.
Elderly
Similar to adults, but use with caution and monitor for cardiac risks due to potential reduced renal/hepatic function and increased sensitivity.
Renal_impairment
For severe renal impairment (e.g., creatinine clearance < 30 mL/min), dose reduction (e.g., 1-2 times daily) or increased dosing interval is recommended. Monitor patients closely.
How to Take
Administer orally, preferably 15-30 minutes before meals for optimal absorption. Shake the suspension well before each use. Use a measuring cup or syringe for accurate dosing.
Mechanism of Action
Domperidone selectively blocks dopamine D2 receptors in the chemoreceptor trigger zone (CTZ) and peripherally in the gastrointestinal tract. This action increases lower esophageal sphincter tone and improves gastric emptying, thereby reducing nausea and vomiting.
Pharmacokinetics
Onset
30-60 minutes.
Excretion
Primarily excreted in feces (66%) and urine (33%) as metabolites within 48 hours.
Half life
Approximately 7-9 hours in healthy subjects; may be prolonged in severe renal impairment.
Absorption
Rapidly absorbed after oral administration; however, low bioavailability (around 15%) due to extensive first-pass metabolism in the liver.
Metabolism
Extensively metabolized in the liver primarily by CYP3A4 hydroxylation and N-dealkylation.
Side Effects
Contraindications
- •Hypersensitivity to domperidone or any excipients.
- •Prolactin-releasing pituitary tumor (prolactinoma).
- •Patients with known existing prolongation of cardiac conduction intervals, particularly QTc, or significant electrolyte disturbances (hypokalaemia, hyperkalaemia, hypomagnesaemia), or underlying cardiac diseases (e.g., congestive heart failure).
- •Moderate to severe hepatic impairment.
- •Concomitant use with potent CYP3A4 inhibitors (e.g., ketoconazole, erythromycin, clarithromycin, ritonavir).
- •Conditions where stimulation of gastric motility could be harmful (e.g., gastrointestinal hemorrhage, mechanical obstruction, perforation).
Drug Interactions
Anticholinergics (e.g., atropine, dicyclomine)
May antagonize the prokinetic effect of domperidone.
Antacids/H2 blockers (e.g., omeprazole, ranitidine)
May reduce domperidone bioavailability. It is recommended to take domperidone before meals and antacids/H2 blockers after meals.
QTc prolonging drugs (e.g., certain antipsychotics, antidepressants, antiarrhythmics, some antibiotics)
Increased risk of QTc prolongation. Avoid co-administration.
Potent CYP3A4 inhibitors (e.g., ketoconazole, erythromycin, clarithromycin, ritonavir, verapamil, diltiazem)
Concomitant use is contraindicated due to significantly increased domperidone plasma concentrations and an increased risk of QTc prolongation.
Storage
Store below 30°C, protected from light and moisture. Do not freeze. Keep out of reach of children.
Overdose
Symptoms of overdose may include somnolence, disorientation, and extrapyramidal reactions. Management is supportive and symptomatic, including gastric lavage and activated charcoal. ECG monitoring is recommended due to the risk of cardiac arrhythmias.
Pregnancy & Lactation
Pregnancy: Limited data on human pregnancy. Should only be used if the potential benefits outweigh the potential risks to the fetus and under strict medical supervision. Lactation: Domperidone is excreted in breast milk in small amounts. A risk to the breastfed infant cannot be excluded. A decision must be made whether to discontinue breastfeeding or to discontinue/abstain from domperidone therapy, taking into account the benefit of breastfeeding for the child and the benefit of therapy for the woman.
