title: Effects of add-on therapy with NDC-052, an extract from Magnoliae Flos, in adult asthmatic patients receiving inhaled corticosteroids.
abstract: OBJECTIVE
  There is a need for new anti-asthmatic medications with fewer side effects. NDC-052, an extract of the medicinal herb Magnoliae flos, which has a long history of clinical use, was recently found to have anti-inflammatory effects. Herein, we evaluated the effects of NDC-052 as an add-on therapy in patients with mild to moderate asthma using inhaled corticosteroids (ICS).
  
  
  METHODS
  In a non-comparative, multi-center trial, 148 patients taking ICS received NDC-052 for eight weeks. We evaluated their forced expiratory volume in one second (FEV1), morning and evening peak expiratory flow rate (AM and PM PEFR), AM/PM asthma symptom scores, visual analogue symptom (VAS) scores, night-time wakening, frequency of short-acting β2-agonist usage, and adverse events.
  
  
  RESULTS
  After eight weeks, both AM and PM PEFRs were significantly improved. Asthma symptom scores, VAS scores, the frequency of nights without awakening, and the frequency of β2-agonist use were also reduced. Most of the adverse drug reactions were mild and resolved spontaneously.
  
  
  CONCLUSIONS
  The addition of NDC-052 to ICS had a beneficial effect on asthma control in patients with mild to moderate asthma, with good tolerability and fewer side effects. Further studies are necessary to evaluate the effects of NDC-052 in patients with severe and/or refractory asthma.
