Title: Real Life Effectiveness of Symbicort Maintenance and Reliever Therapy (SMART) in Asthma Patients Across Asia: SMARTASIA
Brief Summary: The purpose of this study is to compare whether Symbicort Maintenance \& Reliever Therapy (SMART) is more effective in uncontrolled asthmatic patients than their current therapy in a real life situation.
