In this study, we first performed a disintegration test of the voglibose orally disintegrating (V-OD) tablet immersed in jelly-wafer (JW, V-ODims/jw) for 10 min and compared it with the disintegration time of V-OD that was not immersed in JW. We then orally administered the V-ODims/jw tablet to 7 healthy adults and compared the shift in blood glucose levels (BGLs), after loading with a sucrose solution (Suc-sol, 100 g/150 mL), with that after administration of the non-immersed V-OD tablet. The disintegration time of V-ODims/jw tablet was shorter than that of V-OD. When administered to healthy adults, the BGL after loading with Suc-sol was higher with V-ODims/jw tablet administration than with V-OD tablet. We predict that the expression of the efficacy of voglibose is reduced as a result of the interaction between voglibose and the polysaccharide, xanthan gum (XG), since it is a common additive in JW. This study shows that deglutition aids with additives that do not affect pharmacokinetics must be carefully selected for administering along with pharmaceuticals, because of a suggested possibility that the interaction between these pharmaceuticals and the additives in the deglutition aids weaken the drug efficacy. A more careful selection of deglutition aids from the wide selection of medication is especially important when administered to patients who use these deglutition aids often, such as elderly individuals or individuals with a deglutition disorder.
