The evaluation of the potential use of a dye as indicator of in vivo drug release from a medicated chewing gum is described. The device is a three-layer tablet obtained by direct compression consisting of a gum core, and two external protective soluble layers to prevent gum adhesion to the punches of the tableting machine. The active ingredient and a colorant are contained in the gum core. To evaluate the drug and dye release from the formulations, a chew-out study was performed by a panel of volunteers. The results obtained suggest that the use of a dye could be useful to indicate the chewing time needed to complete drug delivery from medicated chewing gums.

Abstract
The evaluation of the potential use of a dye as indicator of in vivo drug release from a medicated chewing gum is described. The device is a three-layer tablet obtained by direct compression consisting of a gum core, and two external protective soluble layers to prevent gum adhesion to the punches of the tableting machine. The active ingredient and a colorant are contained in the gum core. To evaluate the drug and dye release from the formulations, a chew-out study was performed by a panel of volunteers. The results obtained suggest that the use of a dye could be useful to indicate the chewing time needed to complete drug delivery from medicated chewing gums.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
