Abstract

A supramolecular synthon approach was exploited to design amorphous solid dispersions (ASDs) of drugs containing an amino aromatic nitrogen moiety and a polyacrylic acid polymer. The interaction between a drug and polymer was confirmed by differential scanning calorimetry, spectroscopy (IR and 15N NMR), and X-ray crystallography. The interaction decreased the molecular mobility, conferred exceptional physical stability and enhanced the drug dissolution.
