Esomeprazole, as a proton pump inhibitor, requires strict avoidance of specific contraindications, foods, and restrictions to ensure medication safety and effectiveness. The following provides a detailed explanation from three aspects: the classification of taboo groups, taboo foods, and special restrictions.

1. Taboo population

(1) Allergic individuals

It is contraindicated for individuals allergic to esomeprazole or other benzimidazole compounds, as it may cause serious allergic reactions such as urticaria and angioedema.

(2) Pregnant women

Animal experiments have shown that high doses may cause embryotoxicity, and human data is limited. Use should be avoided during pregnancy unless the potential benefits outweigh the risks.

(3) Lactating women

Medications can be secreted into breast milk, which may affect the secretion of gastric acid in infants. It is recommended to suspend breastfeeding or use alternative medications during treatment.

(4) Severe liver and kidney dysfunction patients

Children Pugh grade C cirrhosis patients need to adjust the dosage or discontinue use; Patients with severe renal insufficiency (eGFR<30mL/min) need to closely monitor the risk of drug accumulation.

2. Taboo foods and drugs

(1) High-fat diet

Taking it on an empty stomach one hour before meals can ensure optimal absorption, as high-fat foods may delay the effectiveness of the medication and reduce the acid suppressing effect.

(2) CYP2C19 inhibitors

Powerful inhibitors such as fluconazole may increase blood drug concentrations, and when used in combination, the dosage of esomeprazole needs to be adjusted to avoid excessive acid suppression.

(3) Antiplatelet drugs

The combination with clopidogrel may weaken the efficacy of the latter and increase the risk of thrombosis. It is recommended to switch to PPI with less interaction, such as pantoprazole.

3. Special Restrictions

(1) Long term usage monitoring

Regular assessment of magnesium levels, vitamin B12, and bone density is necessary to prevent hypomagnesemia or osteoporosis if medication is continued for more than one year.

(2) Infection risk control

Long term suppression of gastric acid may increase the risk of Clostridium difficile infection, and diarrhea patients need to undergo timely pathogen testing.

(3) Medication for the elderly

Patients over 65 years old do not need to adjust their dosage, but caution should be taken when combining multi drug therapy to avoid drug interactions and the risk of falls.
