Abstract

 Background: Drug–drug interactions could cause failure in treatment and adverse events. Objectives: To determine the prevalence and characteristics of drug-drug interactions in treatment for coronary artery diseases. Materials and methods: We conducted a cross-sectional study on the prescribing for outpatients with coronary artery diseases at a hospital in Can Tho in August 2018. The drugs were recorded from the prescriptions and the drug-drug interactions were checked on Drugs.com website. We used only major drug-drug interactions. Results: In total, 683 patient’s prescription were included (mean age 63.4; 64.3% female). The prevalence of drug- drug interactions is 19.3%. The interaction between clopidogrel and proton pump inhibitors-PPIs (omeprazole, esomeprazole, rabeprazole) is the most common in the study. Patients who received five or more drugs were more likely to experience drug-drug interactions (OR = 6.36; 95% CI: 2.54-15.96). Conclusion: Drug-drug interactions are common among patients with coronary artery diseases. The incidence of drug-drug interactions increased with the increase in number of drugs prescribed. Further studies should be conducted to determine the association between drug-drug interactions and physicians’ characteristics.
