[Bitterness of the mixture of clarithromycin dry syrup and carbocisteine preparation--difference between brand name and generic drugs].

The purpose of this study was to assess the bitterness intensity and pH of the solutions of clarithromycin dry syrup (CAM-DS), carbocisteine preparation (CC), and the concomitant use of both drugs. We conducted 6 types of human gustatory sensation tests with 6 healthy male volunteers. As a result, there was almost no difference in the bitterness intensity of CAM-DS between the branded (the latest and former preparations) and the generic formulations.
