Chemometric methods for the quantification of crystalline tacrolimus in solid dispersion by powder X-ray diffractrometry.

Akhtar Siddiqui et al.

Journal of pharmaceutical sciences, 103(9), 2819-2828 (2014-03-04)

The objective of this study was to develop powder X-ray diffraction (XRPD) chemometric model for quantifying crystalline tacrolimus from solid dispersion (SD). Three SDs (amorphous tacrolimus component) with varying drug to excipient ratios (24.4%, 6.7%, and 4.3% drug) were prepared.
