Nicotine permeability across the buccal TR146 cell culture model and porcine buccal mucosa in vitro: effect of pH and concentration

open access: yesEuropean Journal of Pharmaceutical Sciences, 2002
The present study was conducted to investigate and compare the effect of pH and drug concentration on nicotine permeability across the TR146 cell culture model and porcine buccal mucosa in vitro. As a further characterization of the TR146 cell culture model, it was explored whether the results were comparable for bi-directional and uni-directional ...

Two types of core/shell fibers based on carboxymethyl chitosan and Sodium carboxymethyl cellulose with self-assembled liposome for buccal delivery of carvedilol across TR146 cell culture and porcine buccal mucosa.

International Journal of Biological Macromolecules, 2019
Two novel core-shell fibers which could self-assemble liposome were fabricated based on bioadhesive polymer carboxymethyl chitosan (CMCS) and Sodium carboxymethyl cellulose (CMC-Na), separately. The shell layers were CMCS/PVA and CMC-Na/PVA, respectively,

Buccal delivery of metformin: TR146 cell culture model evaluating the use of bioadhesive chitosan discs for drug permeability enhancement

International Journal of Pharmaceutics, 2013
The oral cavity is considered an attractive site of drug administration. Metformin is currently, used in oral diabetes treatment. The aim of the current study was to study the feasibility of metformin, to permeate the buccal epithelium applying a bioadhesive and permeation enhancing drug delivery system.

Promoting effects of chemical permeation enhancers on insulin permeation across TR146 cell model of buccal epitheliumin vitro

Drug and Chemical Toxicology, 2011
To find potential enhancers for facilitating the buccal delivery of insulin, a TR146 cell-culture model of buccal epithelium, cultured on commercially available insert plates, was used to evaluate the permeability-enhancing effects of several traditional and new types of chemical enhancers, including N-acetyl-L-cysteine (NAC), sodium deoxycholate (SDC),
