WebAccording to the solubility diagrams by Higuchi and Connors, the phase solubility curve of IBG and HP-β-CD is a typical AL-type curve. The regression coefficient (R 2) exceeded 0.99, and the slope value (0.1151) was less than 1, indicating that the stoichiometry ratio of the IBG/HP-β-CD system was 1:1. The Ks of IBG/HP-β-CD was calculated ... WebThe study of phase solubility was based on the Higuchi & Connors method and showed an impressive enhancement of the miscibility of furosemide with water. In fact, a 11 fold increase of the drug solubility was recorded for the inclusion complex, in the first stages of dissolution. The experimental results of this work show that 2-Hydroxypropyl ...
