title: Effectiveness and tolerability of paroxetine controlled release (CR) in the treatment of major depressive disorder: an open-label, prospective, multi-center trial in Korea.
abstract: OBJECTIVE
  This study evaluated the effectiveness and tolerability of paroxetine controlled release (CR) for the treatment of Korean patients with major depressive disorder (MDD) in a naturalistic treatment setting.
  
  
  METHODS
  One hundred and ninety patients with MDD were enrolled in this study. The Hamilton Depression Rating Scale-17 item (HAMD-17) and Clinical Global Impression-Severity (CGI-S) scores were measured at the baseline (day 0) and at weeks 1, 2, 4, and 8 (endpoint). The primary measure of effectiveness was a change in the mean HAMD-17 scores from the baseline to the endpoint. The secondary effectiveness measures included a decrease in the HAMD-17 scores of 50% or more at the endpoint compared with the baseline and a change in the mean CGI-S scores from the baseline to the endpoint. Remission was defined as a HAMD-17 score < or = 7 at the endpoint.
  
  
  RESULTS
  The HAMD-17 scores decreased by 56.5% (observed difference, OD = -13.3) (t = 26.63, p < 0.0001) from the baseline. The CGI-S scores also decreased by 50.0% (OD = -2.3) (t = 24.47, p < 0.0001). The response and remission rate at the endpoint was 64.2 and 48.4%, respectively. The adverse events were tolerable. No unexpected or serious side effects were observed.
  
  
  CONCLUSIONS
  Despite the methodological limitations, this study demonstrated that paroxetine CR is effective and tolerable for treating patients with MDD in an East Asian population.
