Several factors should be considered in choosing optimal pharmacotherapeutics strategy including efficacy, safety, availability and cost of the drugs. The objective of this study was to assess potential drug-drug interactions and risk factors in outpatients taking cardiovascular drugs at Jimma University specialized hospital.</p><p><strong>Methods:</strong> A cross-sectional study was conducted from Feb. to April, 2011on patients visiting the cardiac clinic of Jimma University Specialized hospital. A sample of 332 outpatients who were taking cardiovascular medications at study clinic was studied. MicroMedex software was used to screen drug-drug interactions and SPSS for windows software versions-16.0 was used for data analysis.</p><p><strong>Results:</strong> A total of 1249 drugs with average of 3.76 drugs per prescription were prescribed for the 332 patients. The frequency of potential DDIs was found to be 241 (72.6%). Among these 200 (67.3%) were of "moderate" severity and 164 (55.2%) were delayed in onset. The most common potential DDI observed was between Enalapril and Furosemide (20%). Patients who prescribed many drugs (AOR=4.09; P=0.00) by medical intern had a higher risk of developing potential DDIs (AOR=4.6; P=0.00).</p><p><strong>Conclusions:</strong> Patients with cardiovascular disorders are subjected to high risk of potential drug-drug interactions and the number of drugs prescribed and educational level of the prescribers has a high significantly associated with the occurrence of potential drug-drug interactions. Therefore, it is imperative that further studies need to be conducted to identify reasons for and tackle the problem and provide appropriate mechanisms for management.</p> ER -
