The importance of configurational disorder in crystal structure prediction: the case of loratadine
A crystal structure prediction study of loratadine demonstrates the important role of experimentally observed disorder in determining the relative stability of the known monotropically related polymorphs.</p
Transforming Computed Energy Landscapes into Experimental Realities – the Role of Structural Rugosity
We exploit the possible link between structural surface roughness and difficulty of crystallisation. Polymorphs with smooth surfaces may nucleate and crystallise easier than polymorphs with rough surfaces. The concept is applied to crystal structure prediction landscapes and reveals a promising complementary way of ranking putative crystal structures
Continuous Cocrystallization for Dissolution Rate Optimization of a Poorly Water-Soluble Drug
A continuous
manufacturing process, hot melt extrusion (HME), was
employed for the development of high quality carbamazepine–saccharin
(CBZ–SCH) cocrystals. The produced cocrystals were compared
with a prototype prepared by a solvent method. It was found that processing
parameters such as temperature, screw speed, and screw configuration
were the critical processing parameters. In-line near-infrared analysis
demonstrated that cocrystallization takes place gradually during the
process along the extruder’s mixing zones. Further characterization
of the extruded cocrystals proved that the manufactured highly crystalline
cocrystals were similar to the prototype but had improved CBZ dissolution
rates. Continuous manufacturing of cocrystals of water-insoluble drugs
is a novel and robust approach
