Abstract Thermoresponsive polymers are a class of smart materials that exhibit change in their physical properties with temperature, which make them unique and useful materials in a wide range of biomedical applications. Soluplus®, a thermoresponsive block graft copolymer with poly(vinyl acetate) PVAc and poly(vinyl caprolactam) PVCL block grafted on a poly(ethelyne glycol) PEG backbone in a ratio of 30:57:13 respectively, is marketed by BASF Corporation, it aids in solubilizing and increasing...

Abstract Reducing the promiscuous tropism of native adenovirus by using fiberless adenovirus is advantageous towards its use as a gene therapy vector or vaccine component. The removal of the fiber protein on native adenovirus abrogates several undesirable interactions; however, this approach decreases the particle’s physical stability. In order to create stable fiberless adenovirus for pharmaceutical use, the effects of temperature and pH on the particle’s stability profile must be...

Abstract The SeDeM Expert Diagram System is a galenic pre-formulation system, which evaluates the suitability of excipients and active pharmaceutical ingredients (API's) for direct compression into tablets as well as predicting possible formulations (i.e. ratios of API:excipient) to obtain acceptable direct compressible tablets. In this study, the prediction ability of the SeDeM Expert Diagram System with a special focus on testing the limits of the system was investigated. Three different...

ABSTRACT The main objective of this study was to prepare a solid self micro-emulsifying drug delivery system (S-SMEDDS) by spray drying liquid SMEDDS with an inert solid carrier Aerosil 200 to improve the dissolution rate and permeability of Chlorthalidone (CTD). The liquid SMEDDS was composed of CTD, oleic Acid, Tween 20, PEG 200. Preliminary screening was carried out to select proper components combination. Solubility of Chlorthalidone was determined in various vehicles. Ternary phase diagram...

he aim of the present study was to develop a novel semi-solid self-microemulsifying drug delivery system (SMEDDS) using Gelucire® 44/14 as oil with strong solid character to improve the oral bioavailability of poorly soluble drug valsartan. The solubility of valsartan in various excipients was determined, the pseudo-ternary phase diagram was constructed in order to screen the optimal excipients, and DSC analysis was performed to evaluate the melting point of SMEDDS. The optimal drug-loaded...
