The natural bile acid surfactant sodium taurocholate (NaTC) as a coformer in coamorphous systems: Enhanced physical stability and dissolution behavior of coamorphous drug-NaTc systems
The amorphization of 18 different drugs on milling with one mole equivalent sodium taurocholate (NaTC) was investigated. In all cases the X-ray powder pattern showed an amorphous halo after milling at room temperature or ...
Application of ball milling for highly selective mechanochemical polymorph transformations
(American Chemical Society, 2018-06-07)
Milling is an important secondary processing technique in the manufacture of pharmaceuticals, primarily used as a particle size reduction process. p-Aminobenzoic acid (PABA), m-aminobenzoic acid (MABA), o-aminobenzoic acid ...
Use of sublimation catalysis and polycrystalline powder templates for polymorph control of gas phase crystallization
(American Chemical Society, 2018-05-08)
In pursuit of a solvent-free green alternative to solution-based processes, we have applied the combined use of catalytic additives and polycrystalline powder templates for polymorph control of gas phase crystallization ...
Cocrystal forms of the BCS class IV drug sulfamethoxazole
(American Chemical Society, 2018-05-23)
Sulfamethoxazole, smz, is an antibiotic that is classified as a Biopharmaceutics Classification System (BCS) class IV, low solubility and low permeability drug. Cocrystal formation has been examined in an attempt to improve ...
