Phase solubility measurements of SBE 7-β-CD and valsartan were performed using the Higuchi-Connors technique . In separate conical flasks holding 10 ml of distilled water having increasing concentrations of SBE 7 -β-CD starting from 0.5 to 5 mM, an excess of valsartan was added.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 ).Phase solubility studies. Solubility measurements were performed in triplicate using the method reported by Higuchi and Connors (Higuchi et al., 1965). An excess amount of ALLO was added to the aqueous solutions of each carrier containing increasing concentrations of the individual carrier (i.e., 0, 1, 5, and 10 % w/v).

The phase solubility technique permits the evaluation of the affinity between HPβCD and raloxifene in water. Phase solubility studies were performed according to the method reported by Higuchi and Connors . As given in Table 1, raloxifene was taken into vials in an excess amount, and 20 ...Dec 15, 2022 · The solubility of CUR increased linearly with increasing concentrations of β-CD, represented as an A L type phase solubility curve (Higuchi & Connors, 1965; Jiang et al., 2019). The results of ANONA of the phase solubility model were provided in Table 1. F value (409.54) was extremely significant (p value < 0.001) suggesting that the model was ... Phase Solubility Studies. Phase solubility studies were carried out at room temperature (21 ± 1°C) following the method of Higuchi and Connors . Excess amounts of OME were weighed in glass flasks to which 10 ml of boric/borate buffer pH = 10 were added. These flasks contained increasing amounts of βCD (0–1.5%, w/v) or MβCD (0–5%, w/v).T.

Abstract Solubility is one of the most important physicochemical properties studied during pharmaceutical preformulation. For liquid dosage form development, accurate solubility data are essential to ensure the robustness of the finished product.Moreover, phase-solubility analysis shows that propyl-paraben and ethylparaben, at room temperature, can also form solid solutions whose solubility is related to the composition of the solid phase at equilibrium. ...
