Plain English summary of protocol

Background and study aims
Melagrião® is a medicine made from six medicinal plants with known action in the respiratory tract (breathing system): Mikania glomerata, Cephaelis ipecacuanha, Aconitum napellus, Polygala senega, Myroxylon balsamum and Nasturtium officinale. The aim of this study is to evaluate the safety and the genotoxic (DNA-damaging) potential of Melagrião® syrup in healthy volunteers.

Who can participate?
Healthy volunteers aged 18-50

What does the study involve?
Participants are randomly allocated to take either Melagrião® syrup or a placebo (dummy medicine) as four daily doses for 28 uninterrupted days. Blood samples are taken and clinical and laboratory tests are performed at the start of the study, during the treatment period and at the end of the study.

What are the possible benefits and risks of participating?
If it is found to be safe this medication will be of great value for the treatment of respiratory (lung) diseases. Melagrião® can cause some gastric (stomach) disorders, vomiting and diarrhoea. Blood sampling is a safe procedure and may cause mild discomfort as well as a small purple spot that often resolves without major problems.

Where is the study run from?
Federal University of Ceara (Brazil)

When is the study starting and how long is it expected to run for?
May 2007 to October 2007

Scientific titleClinical toxicology of Melagrião® syrup in healthy volunteers: a randomized parallel trial
Study objectivesMelagrião® syrup is safe to use in healthy volunteers.
Ethics approval(s)Research Ethics Committee of the Federal University of Ceará, accredited by the National Health Council / MS (Protocol 255/07), 11/08/2007
Health condition(s) or problem(s) studiedRespiratory diseases
Intervention48 adult subjects were randomly divided into two groups: Placebo (n=24) and Melagrião® (n=24). In order to have a uniformity of the groups the volunteers were randomized by means of lottery, using sealed envelopes. The subjects were treated for 28 uninterrupted days with 120 mL of Melagrião® or Placebo, divided into four daily doses. Clinical and laboratory evaluations were performed in the pre-study, during the treatment period and after the end of the study. The genotoxicity of Melagrião® was investigated through the comet assay.
