Grinding of drugs with pharmaceutical excipients at cryogenic …
The effect of cryogenic grinding on the piroxicam and its mixtures with polyvinylpyrrolidone (PVP) was studied by powder X-ray diffraction and differential scanning calorimetry (DSC). The crystallization of the amorphous piroxicam obtained during cryogrinding showed two events in a DSC curve (noticeable for pure piroxicam, and …
