Long-term use of PPIs has also been associated with low levels of magnesium (hypomagnesemia). Analysis of patients taking PPIs for long periods of time showed an increased risk of heart attacks.

Therefore, it is important to use the lowest doses and shortest duration of treatment necessary for the condition being treated.

  • For GERD, 20 or 40 mg of esomeprazole is given once daily for 4-8 weeks. In children ages 1-11, the dose is 10 or 20 mg daily.
  • For the treatment of H. pylori, 40 mg is administered once daily in combination with amoxicillin and clarithromycin for 10 days.

Esomeprazole capsules should be administered one hour before meals, swallowed whole and should not be crushed or chewed. Patients with difficulty swallowing can open the capsule and mix the pellets with applesauce. The applesauce should not be hot and the pellets should not be chewed or crushed.

DRUG INTERACTIONS: Esomeprazole potentially can increase the concentration in blood of diazepam (Valium, Diastat) by decreasing the elimination of diazepam in the liver. Esomeprazole may have fewer drug interactions than omeprazole.

The absorption of certain drugs may be affected by stomach acidity. Therefore, esomeprazole and other PPIs that reduce stomach acid also reduce the absorption and concentration in blood of ketoconazole (Nizoral) and increase the absorption and concentration in blood of digoxin (Lanoxin). This may lead to reduced effectiveness of ketoconazole or increased digoxin toxicity, respectively.
