Highlights: [•] Texture analysis was applied to predict the in vivo disintegration times of ODTs. [•] Optimization process was developed using five different tablets. [•] Optimized texture analysis method was evaluated using independent tablets. [•] Satisfactory prediction was gained in the case of independent tablets. [Copyright &y& Elsevier]

Highlights: [•] Microstructural characteristics of biopolymer cast films were determined by PALS. [•] Macrostructure of the cast films was characterized by the puncture strength. [•] Macrostructural changes were visualized by SEM. [•] Similar trends were found in the macro- and microstructural properties of the films. [•] PALS is useful for the optimization of the composition. [ABSTRACT FROM AUTHOR]

Abstract: The purpose of the present study was to formulate a novel thermoresponsive membrane controlled therapeutic system from Metolose® for possible transdermal application. Metolose® gel shows thermal gelation property, which can be characterized by two (T 1, T 2) temperatures. A sharp decrease of viscosity can be measured at T 1, but gelation can be observed at T 2. Different types of Metolose® polymers were compared considering their thermoresponsive behaviour. Only thermal gelation was observed in the case of Metolose® SM, while Metolose® SH showed a sudden decrease of viscosity at T 1. Since this temperature is above the body temperature, so it should be shifted to the skin temperature in case of possible transdermal application. Modulation of thermoresponsibility was followed by rheological method, and the thermoresponsive drug release from Metolose® gel was studied by static liberation test. Our results demonstrated that the effect of different salts (NaCl, NaHCO3, KCl) of various concentrations in Metolose® SH gel reduced T 1 to the skin temperature, which enabled enhanced drug release.
