 The safety and efficacy of Symbicort®Turbuhaler®maintenance therapy has already been confirmed in several clinical trials and post-marketing investigations. Here we report on a one-year special clinical experience investigation of the safety and efficacy of long-term Symbicort®maintenance therapy in actual clinical settings in asthma patients using Symbicort®for the first time.  An investigation was conducted on 1,464 patients from 314 facilities between January 2010 and June 2012. Among 1,382 patients subject to safety evaluation, 144 patients(10.4%)experienced adverse drug reactions(ADRs). ADRs occurring in five or more patients were palpitation(n=28:2.0%), dysphonia(n=25:1.8%), tremor(n=13:0.9%), muscle spasm(n=8:0.6%), asthma(n=7:0.5%), oral candidiasis(n=6:0.4%)and stomatitis(n=5:0.4%). Unexpected ADRs were 7 asthma and 5 stomatitis. Three cases of 7 asthma were serious but thought to be due to the primary disease(asthma)thus, further investigation considered unnecessary. Other ADRs were considered non-serious and no new issues were observed in the safety profile. No increase in ADRs associated with long-term administration was observed. The Asthma Control Questionnaire(ACQ)score obtained after administration and the proportion of patients with poor asthma control, calculated from this score, were significantly improved compared to baseline, as was short-acting β2-agonist inhaler use and frequency, and peak flow rate. We confirmed no new issues regarding safety and efficacy of long-term maintenance therapy with Symbicort®.
