EFFECT OF PERMEATION ENHANCER ON EX-VIVO PERMEATION OF ONDANSETRON HCl BUCCAL TABLETS
AbstractThe objective of the paper is to study the effect of a permeation enhancer, sodium taurocholate on permeation of Ondansetron HCl from bioadhesive buccal tablet formulation by performing ex-vivo permeation experiments using porcine buccal mucosa. Optimized formulation has selected based on in-vitro drug release studies of bilayered bioadhesive buccal tablets. To the optimized formulation, 10mM sodium taurocholate was added to increase the permeation of poorly permeable ondansetron HCl. It is well known that natural surfactants like bile salts increase the permeability of drugs by perturbation of intercellular lipids. The results indicated that, from pure drug solution (5 mg/mL) about 88.63% cumulative percentage of drug permeated across porcine buccal mucosa with flux of 0.0235 mg.h-1cm-2. However, the optimized formulation with sodium taurocholate increased flux (0.0523 mg.h-1cm-2) and cumulative amount of drug permeated (65.44%) in comparison to formulation without permeation enhancer (38.45%, 0.0186 mg.h-1cm-2) with enhancement ratio of 2.81.
