Kee Interventional Radiology Division of Interventional Radiology, Department of Radiology, UCLA Medical Center, Los Angeles, CA USA 90095Learning Objectives: Background Conclusion and/or Teaching Points1. Review the most recent literature on the most commonly used medications in IR is progressively becoming a more clinical and independent discipline, with a wide array of disease processes to treat 1. An effective knowledge and understanding of the most commonly used medications in IR is interventional radiology (IR), including antibiotics, anti-platelet and antithrombotic and manage from head to toe. IR specific pharmacology is becoming increasingly important as interventionalists are essential for patient safety and effective disease management in this progressively clinical discipline agents through compilation of this information into an easy to use IR specific treating complicated acute conditions while managing chronic conditions. With the increasing number of direct referrals, 2. Familiarity with the indications, mechanisms of actions, side effects, doses, and costs of these pharmacopeia. IR physicians sometimes even take on the role of primary physician, and must have a working knowledge of available drugs is the pharmacological foundation for ensuring patient safety and effective disease2. Review and compare the indications, mechanisms of action, side effects, doses, medications for improving their patients’ health. Safely and effectively managing these varying medical conditions management. and cost for each medication. pharmacologically may prove difficult, especially for physicians-in-training. Thus, an up-to-date IR specific 3. To provide the best and most innovative medical care for our patients, interventional radiologists3.
