WebThe permeability of HCT was found to be dependent on the dissolution properties of the formulations in both PAMPA and cellular barrier experiments. Thus, co-amorphization of HCT with L- and D-ARG demonstrated the possibility to enhance the dissolution and thereby the permeation potential of a BCS class IV drug. Permeability is a property of porous materials that is an indication of the ability for fluids (gas or liquid) to flow through them. Fluids can more easily flow through a material with high permeability than one with low permeability.
