Summary:

      This is a single and multiple dose, single centre, open-label, one-way, pharmacokinetics,
      safety and tolerability clinical trial of Phase I to be performed in Chinese healthy male and
      female volunteers. Twenty-four (24) healthy male and female Chinese volunteers will be
      included in the study. Drop-out subjects will not be replaced. The study has been designed in
      agreement with the Chinese Technical Guideline on Clinical Pharmacokinetic Research of
      Chemical Drugs, 18 March 2005 and the European Guideline on the Investigation of
      Bioequivalence. No randomisation will take place in this study. All the participant will
      receive the same treatment with the investigational medicinal product (IMP), i.e. NAC, 300
      mg/ 3 mL solution for injection.
