How should esomeprazole (Nexium) be administered through a nasogastric (Ryle) tube?

How to Administer Nexium (Esomeprazole) Through a Ryle Tube (Nasogastric Tube)

Open the Nexium capsule and empty the intact granules into a 60 mL catheter-tipped syringe, mix with 50 mL of water, shake vigorously for 15 seconds, and deliver through the nasogastric tube within 30 minutes, followed by flushing with additional water. 1

Step-by-Step Administration Protocol

For Nexium Delayed-Release Capsules:

1. Open the capsule and empty the intact granules into a 60 mL catheter-tipped syringe
2. Add 50 mL of water to the syringe containing the granules
3. Replace the plunger and shake the syringe vigorously for 15 seconds
4. Hold the syringe tip up and check for granules remaining in the tip
5. Attach the syringe to the nasogastric tube
6. Deliver the contents through the nasogastric tube into the stomach
7. Flush the tube with additional water (at least 30 mL recommended) 2, 1

For Nexium For Delayed-Release Oral Suspension:

1. Add 15 mL of water to a catheter-tipped syringe
2. Add the contents of the Nexium packet (10 mg, 20 mg, or 40 mg as prescribed)
3. Shake immediately and leave 2-3 minutes to thicken
4. Shake again and inject through the nasogastric or gastric tube (French size 6 or larger) within 30 minutes
5. Refill the syringe with 15 mL of water
6. Shake and flush any remaining contents from the tube into the stomach 1

Critical Safety Points

Use only a catheter-tipped syringe when administering Nexium through a nasogastric tube to comply with ISO 80369-3 standards and prevent misconnection errors 2, 3, 2

Do not administer the granules if they have dissolved or disintegrated - the enteric coating must remain intact for proper drug delivery and efficacy 1

Administer immediately after preparation - the suspension must be used within 30 minutes of mixing 1

Important Considerations

Tube Size Requirements:

• For oral suspension: Use French size 6 or larger 1
• Research shows that 6 French tubes may become obstructed; 8 French tubes are preferable for reliable delivery 4

Bioavailability:

Nasogastric tube administration of esomeprazole enteric-coated pellets provides bioavailability similar to oral dosing when administered correctly 5. The 90% confidence intervals demonstrated bioequivalence between nasogastric and oral administration (0.87-1.08 for AUC and 0.93-1.25 for Cmax).

Flushing Protocol:

Flush the tube before, between (if giving multiple medications), and after each drug with 30 mL of water to prevent tube occlusion 3, 2. This is particularly important for small diameter nasogastric tubes.

Drug-Feed Interactions:

Stop enteral feeding temporarily when administering esomeprazole if possible, as the site of drug delivery affects efficacy 2, 3, 2. Administration directly into the duodenum (rather than stomach) can reduce drug availability.

Common Pitfalls to Avoid

• Never crush or chew the granules - this destroys the enteric coating and compromises drug efficacy 1
• Never mix multiple medications together before administration through the tube - administer each drug individually with flushing between medications 3, 2
• Never shake a low-dose ENFit tip syringe to remove drug moat - this exposes the environment to the drug and affects dosing accuracy 2, 3, 2
• Never store prepared suspensions for later use - they must be administered immediately 1

Special Populations:

In patients with subarachnoid hemorrhage or critical illness, be aware that intestinal drug absorption may be severely impaired for at least 7 days, potentially reducing the effectiveness of enterally administered esomeprazole 6.
