Comparative Assessment of Different Dissolution Apparatus for Floating Drug Delivery Systems
INTRODUCTION Dissolution testing is an in vitro technique of great importance in formulation and development of pharmaceutical dosage forms,as it can be used as a substitute for in vivo studies under strictly defined and specified conditions (1). For the comparison of in vitro dissolution data and for use of such data for in vivo bioequivalence testing and in vitro-in vivo correlations (IVIVC) ...
متن کاملDesign and Evaluation of a Novel Bio-Mimicking In Vitro Dissolution Test Apparatus for Floating Drug Delivery Systems
The aim of the present study was to design a new biorelevant dissolution test apparatus for evaluating floating drug delivery systems. The gastric fluid secretion rate, volume of gastric fluid present in the stomach, and gastric emptying from the pylorus opening were taken into consideration. The material of construction was borosilicate glass. In vitro dissolution testing of pharmaceutical dos...

15 صفحه اولFloating Drug Delivery Systems: a Novel Approach
During the past few decades, numerous oral drug delivery systems have been developed to act as drug reservoirs from which the active substance can be released over a specific period of time at a predetermined and controlled rate. It is evident from the recent scientific and patent literatures that an increased interest in novel oral controlled release dosage forms that designed to be retained i...
متن کاملFloating drug delivery systems: A better approach
The purpose of writing this review on floating drug delivery systems (FDDS) was to compile the recent literature with special focus on the principal mechanism of floatation to achieve gastric retention. It is known that differences in gastric physiology (such as, gastric pH, motility) exhibit both intraas well as inter-subject variability demonstrating significant impact on gastric retention ti...
