Three microemulsion systems were applied as solvents for polymorph screening of seven active pharmaceutical ingredients (APIs): carbamazepine, piroxicam, sulfaguanidine, nitrofurantoin, theophylline, quercetin, and diflunisal. All the recrystallized compounds were examined by using powder X-ray diffractometry, differential scanning calorimetry, elemental analysis

Copper(II) complexes with the non-steroidal anti-inflammatory drug diflunisal in the presence of N,N-dimethylformamide or nitrogen donor heterocyclic ligands (pyridine, 1,10-phenanthroline, 2,2'-bipyridine or 2,2'-bipyridylamine) have been synthesized and characterized. The deprotonated diflunisal ligands are coordinated to Cu(II) ion through carboxylato oxygen
