How does erythromycin interact with antacids, potentially reducing its absorption and what timing considerations are recommended to ensure optimal therapeutic effects?
1. Erythromycin’s absorption is reduced by antacids as they increase gastric pH. They should be taken at least 2 hours apart.
2. Antacids can hinder erythromycin absorption by altering stomach pH. For best effects, take erythromycin 2 hours before antacids.
3. To avoid interaction, erythromycin should be taken 2 hours before or after antacids, since they can neutralize stomach acid, impairing drug absorption.
