Abstract
Antiplatelet and anticoagulation agents are increasingly prescribed for secondary prophylaxis in patients with cardiovascular and cerebrovascular diseases. These drugs are associated with an increased risk of gastrointestinal bleeding, including peptic ulcer bleeding. It is difficult to decide when to restart the agents after peptic ulcer bleeding in these patients because the risk of rebleeding and thromboembolism should be balanced. The Korean College of Helicobacter and Upper Gastrointestinal Research revised the guidelines for drug-induced peptic ulcers as evidence-based guidelines using a de novo process. This paper introduces new recommendations on the resumption of antiplatelet and anticoagulation agents after peptic ulcer bleeding based on the revised guidelines for drug-induced peptic ulcers.
