Esomeprazole is a PPI used once daily in children for GERD and erosive esophagitis; give before meals.
Provides potent acid suppression with once-daily dosing; some severe cases require twice-daily regimens under specialist care.
Granule packets for oral suspension make administration easier for infants and feeding-tube patients.
Consider genetic variability in CYP2C19—poor metabolizers achieve higher exposure; monitor for adverse effects when combining with interacting drugs.
Long-term therapy warrants periodic reviews for infection risk, nutrient status, and necessity of ongoing suppression.
Taper gradually after symptom control to limit rebound acid hypersecretion.
Esomeprazole is used for pediatric GERD and erosive esophagitis healing.
Strong acid suppression supports symptom control and mucosal healing when indicated.
| Condition | Age Range | First Line? | Notes |
|---|---|---|---|
| Healing and maintenance of erosive esophagitis | Infants, children, adolescents | Yes | Dose once daily based on weight (BID for refractory cases). Continue for 4–8 weeks, then reassess maintenance needs every 6–12 months. |
| Symptomatic gastroesophageal reflux disease | Children and adolescents | Yes | Use 4–8 week courses coupled with lifestyle interventions (meal timing, weight management). Step down to the lowest effective regimen once symptoms resolve. |
| Helicobacter pylori eradication | Children and adolescents | Yes | Combine with clarithromycin and amoxicillin or metronidazole per susceptibility data; typical course 10–14 days with confirmation testing ≥4 weeks later. |
| Eosinophilic esophagitis proton pump inhibitor trial | Children and adolescents | No | High-dose esomeprazole (1 mg/kg twice daily) for 8 weeks helps identify PPI-responsive disease before initiating topical steroids or elimination diets. |

Esomeprazole’s most frequent adverse effects are headache, diarrhea, and abdominal pain; serious reactions are uncommon but warrant monitoring during prolonged therapy.
Like other PPIs, esomeprazole can alter mineral absorption and gut flora over time. Evaluate the ongoing need for acid suppression at each visit.

Common concerns and practical guidance
Comprehensive administration guidance for esomeprazole in children.
Open packets or capsules and dissolve the granules in 15 mL of water. Stir, let sit for 2–3 minutes, stir again, and drink within 30 minutes. Rinse the cup with water and drink to capture remaining granules. Do not chew or crush granules. Compounded suspensions should be shaken vigorously and measured with an oral syringe.
Document doses on a shared schedule and set phone reminders because symptom improvement can lag several days. Coordinate with pharmacies experienced in compounding to ensure stability for infants.
Emergency contact: Seek urgent care for severe diarrhea, abdominal pain, allergic swelling, or signs of low magnesium (seizures, palpitations).
Pair consistent dosing with positioning strategies, smaller meals, and weight optimization to maximize symptom relief.

Expert pearls and evidence-based tips
Esomeprazole is the S-isomer of omeprazole that irreversibly inhibits the gastric proton pump (H+/K+ ATPase), producing profound and sustained acid suppression.
Enteric-coated granules protect the prodrug from gastric acid. After absorption, esomeprazole diffuses into parietal cell canaliculi, where acidic pH activates it to a sulfenamide that forms covalent bonds with cysteine residues on the proton pump. Acid secretion resumes only after new pumps are synthesized (24–48 hours).

Understanding your child's medication is important. We've created comprehensive guides to help you safely administer Esomeprazole and monitor your child's response to treatment.
Use freshly mixed suspension within 30 minutes. Compounded pharmacy suspensions should be stored per the label, usually refrigerated and discarded after 14 days.
Most courses last 4–8 weeks. Schedule follow-up to reassess, taper, or discontinue once symptoms resolve.
Yes. Disperse granules in water per the label, inject through a ≥6 French tube, and flush with additional water to move remaining granules.
