Cocrystals of Fluconazole with Aromatic Carboxylic Acids: Competition between Anhydrous and Hydrated Solid Forms

Through cocrystallization of the broad-spectrum antifungal agent fluconazole (FLZ) with a number of nutraceuticals, we have isolated three distinct solid forms of the drug, namely, anhydrous cocrystal with vanillic acid (VA) and anhydrous and hydrated cocrystals of 4-hydroxybenzoic acid (4OHBA). The new cocrystals have been thoroughly investigated by different analytical techniques, including powder and single crystal X-ray diffractometry (XRD),...
