Comprehensive x-ray scattering studies have characterized the smectic ordering of octylcyanobiphenyl (8CB) confined in the hydrogen-bonded silica gels formed by aerosil dispersions. For all densities of aerosil and all measurement temperatures, the correlations remain short range, demonstrating that the disorder imposed by the gels destroys the nematic (N) to smectic-A (SmA) transition. The sme...

Objective Eudragits are widely used polymers in the production of oral sustained release dosage forms. The application of these polymers in the production of inert insoluble matrices has been investigated. However the effect of particle size, compaction force and presence of Aerosil 200 as a glidant on the properties of Eudragit RS and RL matrices prepared by direct compression of their physic...

Since Cohn's cold ethanol method was introduced into routine practice of plasma fractionation in this country, little attention has been paid to other approaches for isolating or fractionating plasma proteins , at least in the level of industrial production. Recently, however, in Western European countries , usefulness of selective adsorption of plasma proteins to various adsorbents is attracti...

The reaction of four different basic ionic liquid precursors with Aerosil 300 is presented. Chemisorbed imidazolium and phosphonium cations, with silanolate anions as part of the silicatic support, were obtained and investigated with various solid state NMR techniques.

A bilayer tablet formulation approach was used to develop a fixed dose combination tablet formulation of drugs Y & Z. The weight of Layer I containing Drug Y and the weight of Layer II A or II B containing Drug Z were 250 mg and 1280 mg, respectively. While Layer I was manufactured using dry granulation, Layer II A and II B were manufactured using a moisture activated dry granulation (MADG) pro...

Previous reports show ineffective transdermal delivery of ketorolac by nanostructured lipid carriers (NLCs). The aim of the present work was enhancement of transdermal delivery of ketorolac by another colloidal carriers, lipid nanocapsules (LNCs). LNCs were prepared by emulsification with phase transition method and mixed in a Carbomer 934P gel base with oleic acid or propylene glycol as penetr...
