Contact Behavior of Microcrystalline Cellulose Pellets Depending on their Water Content

Controlled Release Behaviour of Nifedipine from the Pellets of Gelucire/Microcrystalline Cellulose Blends

The aim of the present study was to prepare matrix pellets loaded nifedipine (NF) as model drug by pellitization technique by using blend of gelucire 50/13 (GL) and glyceryl palmito stearate (GPS) as hydrophilic and hydrophobic carriers in different concentrations. This system was able to prolong the drug release, minimizing the drug related adverse effects and improve bioavailability in differ...

Solubility behavior of cyanophycin depending on lysine content.

Study of the synthesis of cyanophycin (CGP) in recombinant organisms focused for a long time mostly on the insoluble form of CGP, due to its easy purification and its putative use as a precursor for biodegradable chemicals. Recently, another form of CGP, which, in contrast to the insoluble form, was soluble at neutral pH, became interesting due to its high lysine content, which was also assumed...

The influence of microcrystalline cellulose grade on shape and shape distributions of pellets produced by extrusion-spheronization.

In this study, five microcrystalline cellulose (MCC) grades were physically characterized and their extrusion-spheronization behaviours were characterized in terms of water requirements and pellet shape profiles. It was found that the MCC grades differed significantly in the physical properties investigated. Physical properties of MCC were found to influence the water requirement for extrusion-...

Influence of Water on the Structure and Dielectric Properties of the Microcrystalline and Nano-Cellulose

Influence of water in the different states on a structure and dielectric properties of microcrystalline cellulose were studied by of X-ray, thermogravimetry, and dielectric spectroscopy. At research of microcrystalline cellulose (MCC) with different content of water, it is shown that the molecules of water are located in the macropores of MCC and in multimolecular hydrated layers. It is shown t...
