Preparation and transformation of true nifedipine polymorphs: investigated with differential scanning calorimetry and X-Ray diffraction pattern fitting methods
(Elsevier, 2011)
The amorphous → metastable and metastable → stable crystalline phase transitions of nifedipine and their relationship with polymorph composition during storage at controlled temperature/humidity conditions were investigated. ...
Characterization of polymorph transformations that decrease the stability of tablets containing the who essential drug mebendazole
(Elsevier, 2010)
This study investigated the influence of moisture and heat on the stability of mebendazole polymorph C in tablets. The polymorphic forms of mebendazole display significant differences in solubility and therapeutic efficacy ...
