A solid-state approach to enable compounds in preclinical development is used by identifying an amorphous solid dispersion in a simple formulation to increase bioavailability. Itraconazole (ITZ) was chosen as a model crystalline compound displaying p

To evaluate drug-polymer miscibility behavior in four different drug-polymer amorphous solid dispersion systems, namely felodipine-poly(vinyl pyrrolidone) (PVP), nifedipine-PVP, ketoconazole-PVP, and felodipine-poly(acrylic acid) (PAA).Amorphous soli

A typical approach to miscibility analysis of amorphous drug-excipient dispersions involves measuring the glass transition temperature, Tg, using differential scanning calorimetery (DSC). Recently, we discussed two computational methods for the misci

Recognizing limitations with the standard method of determining whether an amorphous API–polymer mixture is miscible based on the number of glass transition temperatures (Tg) using differential scanning calorimetry (DSC) measurements, we have devel

The progressive conversion of crystalline raffinose pentahydrate to its amorphous form by dehydration at 60°C, well below its melting temperature, was monitored by X-ray powder diffraction over a period of 72 h. The presence of defects within the cr

This paper considers an approach to operator-guided real time motion control of robot arm manipulators that's based on the use of configuration space (C-space). The goal is to improve operator performance in a complex environment with obstacles, In s

Physical stability of 12 amorphous solid dispersions was evaluated over 9–22 months under ambient conditions using X-ray powder diffraction. The nine dispersions initially characterized as miscible drug-polymer systems all remained X-ray amorphous

Phase separation in amorphous freeze-dried mixtures is likely in many systems. However, suitable detection methodology has been lacking, as the classical technique, differential scanning calorimetry (DSC), relies upon detection of multiple glass tran

We introduce a novel pattern matching algorithm optimized for X-ray powder diffraction (XRPD) data and useful for data from other types of analytical techniques (e.g., Raman, IR). The algorithm is based on hierarchical clustering with a similarity me
