Description
Overview of the medicine
Devomit (Domperidone) is an antiemetic and prokinetic agent used to treat nausea, vomiting, and certain gastrointestinal motility disorders like dyspepsia and GERD. It works by blocking dopamine receptors in the chemoreceptor trigger zone and in the gut.
Uses & Indications
Dosage
Adults
Oral: 10 mg three times daily (TDS), 15-30 minutes before meals. Maximum duration of treatment should not usually exceed one week. For SR capsule: 30 mg once daily (OD) before meals.
Elderly
Similar to adults, but use with caution due to increased risk of cardiac adverse events. Consider lower doses if prolonged treatment is needed.
Renal_impairment
In severe renal impairment (creatinine clearance <30 mL/min), frequency of dosing should be reduced to once or twice daily, depending on the severity of impairment. Dose should be halved.
How to Take
Devomit should be taken orally, preferably 15-30 minutes before meals. For suspension, shake well before use. Suppositories are for rectal use.
Mechanism of Action
Domperidone acts as a selective peripheral dopamine D2 and D3 receptor antagonist. It increases gastrointestinal motility and tone by blocking dopamine receptors in the gut wall, thereby enhancing esophageal peristalsis, increasing lower esophageal sphincter pressure, and accelerating gastric emptying. Its antiemetic effect is due to its dopamine receptor blocking action in the chemoreceptor trigger zone (CTZ), located outside the blood-brain barrier.
Pharmacokinetics
Onset
30-60 minutes (oral)
Excretion
Approximately 66% excreted in feces and 33% in urine as metabolites. Only a small amount (about 1%) is excreted unchanged.
Half life
7-9 hours (prolonged in renal impairment)
Absorption
Rapidly absorbed orally, but low absolute bioavailability (~15%) due to extensive first-pass metabolism in the gut wall and liver.
Metabolism
Extensively metabolized in the liver by cytochrome P450 enzymes, primarily CYP3A4. Main metabolites are hydroxylated and N-dealkylated derivatives.
Side Effects
Contraindications
- •Hypersensitivity to Domperidone or any component of the formulation.
- •Patients with known prolongation of cardiac conduction intervals (e.g., QT), particularly QTc, patients with significant electrolyte disturbances or underlying cardiac diseases (e.g., congestive heart failure).
- •Concomitant use with potent CYP3A4 inhibitors (e.g., ketoconazole, erythromycin, ritonavir) or with other QT-prolonging drugs.
- •Prolactin-releasing pituitary tumor (prolactinoma).
- •Severe hepatic impairment.
- •Patients with gastrointestinal hemorrhage, mechanical obstruction, or perforation.
Drug Interactions
0
Potent CYP3A4 inhibitors (e.g., ketoconazole, erythromycin, clarithromycin, ritonavir) can increase domperidone plasma levels, increasing the risk of QT prolongation. Concomitant use is contraindicated.
1
QT-prolonging drugs (e.g., some antiarrhythmics, antipsychotics, antidepressants) can increase the risk of cardiac arrhythmias. Concomitant use is contraindicated.
2
Antacids and antisecretory agents may decrease the oral bioavailability of domperidone. Administer domperidone at least 30 minutes before these medications.
3
Dopamine agonists (e.g., bromocriptine, cabergoline) may have their effects antagonized by domperidone.
Storage
Store below 30°C in a dry place, away from light and moisture. Keep out of reach of children.
Overdose
Symptoms of overdose include somnolence, disorientation, and extrapyramidal reactions (e.g., dystonia, dyskinesia). There is no specific antidote. Treatment should be symptomatic and supportive, including gastric lavage and activated charcoal. ECG monitoring is recommended.
Pregnancy & Lactation
Pregnancy: Use of domperidone during pregnancy is not recommended unless the potential benefits outweigh the potential risks to the fetus. Lactation: Domperidone is excreted in human milk in small amounts. A risk to the breast-fed infant cannot be excluded. A decision must be made whether to discontinue breast-feeding or to discontinue/abstain from Devomit therapy, taking into account the benefit of breast-feeding for the child and the benefit of therapy for the woman.
