The quadruple combination of drugs consists of two antibiotics, a proton pump inhibitor, and a bismuth agent, and is primarily used to eradicate H. pylori. The general order is to take the proton pump inhibitor and bismuth agent orally on an empty stomach, and the two antibiotics after meals.
Proton pump inhibitors such as omeprazole and lansoprazole, and bismuth agents such as colloidal bismuth pectin and bismuth complex bismuth aluminate need to be taken before meals.
Two antibiotics can be chosen such as amoxicillin and clarithromycin, which can be taken 1 to 2 hours after a meal, regardless of before or after.
The specific order of taking drugs should consult the relevant professional doctors to avoid self-medication. Quadruple therapy 10 to 14 days to stop the drug, after 1 month should go to the hospital to improve the relevant examination such as blowing test to clarify the efficacy.
