Miconazole Chewing Gum as a Drug Delivery System Application of Solid Dispersion Technique and Lecithin

Abstract

AbstractThe release of the antifungal drug miconazole from chewing gum was evaluated both in vitro and in vivo. It was proved that the addition of lecithin and the application of a miconazole polyethyleneglycol 6000 solid dispersion increased the release of miconazole from chewing gum. The in vitro results correlated well with the in vivo results. 6 healthy volunteers obtained therapeutically active concentrations of miconazole in saliva when they chewed gum. In the microbiological experiments performed, lecithin did not antagonize the anti-Candida albicans effect of miconazole at pH 7.2.
