Graphical Abstract The floating beads were fabricated by a novel wax removal technique. Metronidazole was successfully loaded into the Eudragit® L beads. Adding wax into the beads improved floating properties and drug release behavior. Release kinetics were revealed for better understanding of drug release mechanism.Unlabelled image
