AI Article Synopsis

  • The study measured the diffusion constants of iodide through dentine membranes, finding values consistent with previous research.
  • The diffusion coefficient measured through a polycarbonate membrane was significantly influenced by the unstirred diffusion layer, which affected accuracy.
  • To enhance measurement precision, the authors suggest creating a new experimental setup with double stirring mechanisms for each compartment to minimize the unstirred diffusion layer's thickness.

Article Abstract

The diffusion constants of iodide through dentine membranes were determined. The DI-values were within the range generally obtained by other investigators. When the estimation of the diffusion coefficient through a well defined polycarbonate membrane was calculated the value was strongly affected by the diffusion through the unstirred diffusion layer. By using such an experimental approach it seems necessary to develop a new cell equipped with a double stirring system (one in each compartment) in order to reduce strongly the thickness of the unstirred diffusion layer.

The use of in vitro markers able to reproduce the in vivo permeability and diffusivity of orally administered drugs, could represent an innovative starting point for the formulation of delivery systems, in particular for low soluble and low permeable drugs belonging to BCS class II and IV. Considering the great interest in the green pharmaceutical approaches and the increasing use of natural molecules as novel therapeutic drugs, in this study, rutin, hesperidin and curcumin have been selected as lipophilic model drugs to investigate their possible enhancement of their permeability and bioavailability after oral administration. As the low solubility of the three drugs hinders their application, β-cyclodextrins (CD), amphiphilic natural moieties able to form stable inclusion complexes, have been considered to promote their solubilization.

The particle drifting effect, where nanosized colloidal drug particles overcome the diffusional resistance of the aqueous boundary layer adjacent to the intestinal wall and increase drug absorption rates, is drawing increasing attention in pharmaceutical research. However, mechanistic understanding and accurate prediction of the particle drifting effect remain lacking. In this study, we systematically evaluated the extent of the particle drifting effect affected by drug and colloidal properties, including the size, number, and type of the moving species using biphasic diffusion experiments combined with computational fluid dynamics simulations and mass transport analyses.

This study aimed to investigate the impact of amorphous solubility and colloidal drug-rich droplets on drug absorption. The amorphous solubility of cilnidipine (CND) in AS-HF grade of hypromellose acetate succinate (HPMC-AS) solution was significantly reduced compared to that in non-polymer solution due to AS-HF partitioning into the CND-rich phase. In contrast, AS-LF grade of HPMC-AS has minimal effect on the amorphous solubility.
