In preformulation, information about new drug substances is collected in order to develop the most promising formulations. Typical information gathered in a high-throughput-setup are crystal structure, melting points, solubilities in different solvents, and chemical stability. In this context, we want to address our efforts to the drug transport properties (permeability) of the substances, to be able to assess these in an early phase of development: being able to select the most promising candidates from the vast number of possible drug candidates, and find the most promising formulation strategies for each of them.
We have developed a permeability tool in a microtiterplate format using our novel artificial biomimetic barrier Permeapad®. We transfer the experiments onto a robotic system.
