Journal ArticleDOI
Molecular dynamics in liquid and glassy states of non-steroidal anti-inflammatory drug: ketoprofen.
TL;DR: The differential scanning calorimetry (DSC) study shows that ketoprofen is a non-crystallizing compound and proves that amorphous phase is more soluble than the crystalline phase.
Journal ArticleDOI
Crosslinking: An avenue to develop stable amorphous solid dispersion with high drug loading and tailored physical stability
TL;DR: During dissolution study, the degree of supersaturation in the dissolution medium generated by the crosslinked systems gradually increased and maintained the supersaturation for a longer period, offering a simple method to enhance physical stability and control drug release.
Journal ArticleDOI
Molecular dynamics of amorphous pharmaceutical fenofibrate studied by broadband dielectric spectroscopy
TL;DR: Thermal transition study with the help of differential scanning calorimetry (DSC) shows that the aforesaid active pharmaceutical ingredient (API) is a good glass former.
Journal ArticleDOI
A supramolecular synthon approach to design amorphous solid dispersions with exceptional physical stability.
TL;DR: A supramolecular synthon approach was exploited to design amorphous solid dispersions of drugs containing an amino aromatic nitrogen moiety and a polyacrylic acid polymer, which decreased the molecular mobility, conferred exceptional physical stability and enhanced the drug dissolution.

TL;DR: In this paper, a comprehensive result of investigations on three phosphonium-based room temperature ionic liquids (ILs) of same cation, trihexyltetradecylphosphonium ([PC6C6c6C14]), with different anions viz. chloride, dicyanamide, and bis(trifluoromethylsulfonyl) imide [-NTf2]−, were reported.
