Solubility improvement of progesterone from solid dispersions prepared by solvent evaporation and co-milling [PDF]

, 2020
The aim of this contribution was to evaluate the impact of processing methods and polymeric carriers on the physicochemical properties of solid dispersions of the poorly soluble drug progesterone (PG). Five polymers: hydroxypropyl methylcellulose (HPMC),

Modelling phase separation in amorphous solid dispersions [PDF]

Acta Biomaterialia, 2019
Much work has been devoted to analysing thermodynamic models for solid dispersions with a view to identifying regions in the phase diagram where amorphous phase separation or drug recrystallization can occur. However, detailed partial differential equation non-equilibrium models that track the evolution of solid dispersions in time and space are ...

Solid-state characterization of Felodipine–Soluplus amorphous solid dispersions [PDF]

Drug Development and Industrial Pharmacy, 2015
The aim of the current study is to develop amorphous solid dispersion (SD) via hot melt extrusion technology to improve the solubility of a water-insoluble compound, felodipine (FEL). The solubility was dramatically increased by preparation of amorphous SDs via hot-melt extrusion with an amphiphilic polymer, Soluplus® (SOL).

Comparative study of the potential of poly(2-ethyl-2-oxazoline) as carrier in the formulation of amorphous solid dispersions of poorly soluble drugs [PDF]

, 2019
Despite the fact that solid dispersions are gaining momentum, the number of polymers that have been used as a carrier during the past 50 years is rather limited.
