Overall objective:          

Pharmaceutical SOD forms formulation/development


  • Initiates/generates ideas for product formulation/development based on research and/or pharmacopeia monographs for all available API(s) and final product(s)
  • Evaluates/examines existing/available API(s) for initiated product developments based on physicochemical and biological properties (i.e. solubility, water content, particle size, crystal properties, biological activity and permeability, etc) and the interrelation of these properties that can influence the performance of the drug product and its manufacturability. Based on the results/outcomes, recommends potential suppliers for initiated product developments.
  • Carries out a series of formulation experiments with an ability to correlate the analytical results for sequencing trials to determine the target composition(s)
  • Monitors closely the analytical testing results to achieve the desired target product specification and optimum formulation composition
