Inclusion complexes of fluconazole (HFlu) with β-cyclodextrin (β-CD) and hydroxypropyl- β-cyclodextrin (HP-β-CD) had been prepared by the coprecipitation method. The 1:1 stoichiometry of complexation for both inclusion complexes was achieved in the binary system by phase solubility and fluorimetric study. The inclusion complexes were also characterized by DSC-TGA analyses and ESI–MS spectra. The molecular

cyclodextrin-complex formation equilibria. 1H NMR-pH titrations revealed protonation steps in the highly basic region (log K1 = 11.96) and in the acidic region (log K2 = 1.48). The stability and structure of its complexes with β-cyclodextrin (2-hydroxy)propyl-β-cyclodextrin and sulfobutyl ether-β-cyclodextrin were investigated by 1D and 2D solution NMR spectroscopic techniques. The cyclodextrin complexes of fluconazole
