Polymeric Dispersions of Highly Water Soluble Drug: Tiwari et al. solid dispersions of highly water soluble drug,Used
Delivery time: 8-12 business days (International)
Extended release of solid dispersion of water soluble PHC was successively prepared by coevaporation with Eudragit RLPO in 1: 5 ratios. The sustainment of drug release was effected by drugpolymer ratio and method of preparation. The analysis by spectral techniques (FTIR, FTNMR) suggested possibility of hydrogen bonding. The results of DSC, XRD and SEM studies revealed the reduction in crystallinity of pure drug in solid dispersions as compared to their physical mixtures. The results of solubility studies were in accordance with the in vitro release profile and the order of sustainment of drug release was found in rank order of 0.1 N HCl (pH 1.2)< double distilled water< phosphate buffer (pH 7.4). The results of adsorption studies indicated that Eudragit RLPO had greater capacity to adsorb drug as compared to Eudragit RS100 in phosphate buffer (pH 7.4). The content homogeneity of PHC in granule was very high, as all the components in solid dispersions were dispersed and mixed on the molecule level. The dissolution of PHC, which is highly soluble in water, was markedly improved in the solid dispersions.
By changing our most important processes and
products, we have already made a big leap forward. This ranges from the
increased use of more sustainable fibers to the use of more
environmentally friendly printing processes to the development of
efficient waste management in our value chain.
