文摘During the past few decades floating drug delivery systems(FDDSs)have been developed to prolong gastric retention time and obtain sufficient drug bioavailability[1].To avoid unpredictable time to float due to variable pH of the gastric fluid in each subject and food in the stomach[2],sublimation technique is the new interesting approach to prepare noneffervescent FDDSs[3].The objective of the present study was to develop the low-density film coated floating tablets using sublimable substances.
