Artificial membranes in combination with selected natural oils for drug passive diffusion screening in Ussing type chamber apparatus applied to gastro-retentive systems. | LitMetric

AI Article Synopsis

  • The study developed a technique to screen drug passive diffusion using artificial membranes combined with three oils: cognac, emu, and olive oil.
  • Different artificial membranes were tested for their ability to allow the diffusion of Rhodamine 6G (R6G) compared to real pig intestinal tissues, showing that both membrane composition and oil type affected the diffusion rate.
  • The results indicated that the cellulose nitrate membrane and the emu oil-infused cellulose acetate-nitrate membrane closely matched the diffusion rate of R6G observed in pig intestinal tissue, suggesting their potential for simulating drug absorption methods.

Article Abstract

This study aimed at developing an effective technique for the screening of drug passive diffusion utilising artificial membranes in combination with three selected oils (i.e. cognac, emu, and olive oil). Artificial membranes of varying chemical composition and characteristics have been investigated individually and in combination with the selected oils in terms of the passive diffusion of a fluorescent probe (i.e. Rhodamine 6G or R6G), in a diffusion apparatus as compared to excised pig intestinal tissues. In general, the permeation results showed that the rate and extent of R6G permeation were dependent on the membrane composition as well as the type of oil used. The apparent permeability coefficient (P) value for R6G across the cellulose nitrate membrane (0.197 × 10 ± 0.069 cm/s) was the closest to the P of R6G across the excised pig intestinal tissue (0.210 × 10 ± 0.080 cm/s). The cellulose acetate-nitrate mixture membrane impregnated with emu oil also produced a P value (0.191 × 10 ± 0.010 cm/s) that was relatively close to that of R6G across the excised pig intestinal tissue. The delivery of R6G from gastro-retentive matrix type tablets correlated with the release of R6G from the gastro-retentive tablets.
