Google ScholarMay 11, 2018 · Types of phase-solubility diagrams according to Higuchi and Connors showing how the total drug solubility changes with increasing CD concentration. A-type diagrams are formed when the drug/CD complex is soluble in the aqueous complexation media and they are usually associated with the water-soluble CD derivatives.

Mar 10, 2023 · Phase-solubility profiles and classification of drug/CD complexes according to Higuchi and Connors . Figure 2. In general, one drug molecule (D) forms a complex with one CD molecule in pure water, and, if the complex is water-soluble, an A L -type phase-solubility diagram is observed ( Table 1 ). Using the approach of Higuchi and Connors, phase-solubility studies were performed at increasing concentrations of the three CD. Fig. 2 shows that the solubility of CBD increased linearly with the concentrations of HPβCD and HPγCD which corresponds to the AL type profile (formation of 1:1 inclusion complexes). On the contrary, the phase ...The phase-solubility profiles were determined according to Higuchi & Connors 1965 and Brewster and Loftsson, 2007 [22, 23]. ... Higuchi T, Connors KA.
