The present study was aimed to formulate the solid dispersion incorporated microcapsule to improve the dissolution rate and half life of pioglitazone hydrochloride. The solvent evaporation method was used to formulate the solid dispersion resulted increased dissolution rate, bioavailability and stability. Finally increase the half life of the ... Phase solubility study. Phase solubility studies were carried out according to the method reported by Higuchi and Connors . Excess amounts of MMF were added to 0.1 N HCl solutions (pH-1.2) containing para sulphonatocalix[4]resorcinarene in different molar concentrations and these flasks were then sonicated for 1 h and shaken at a rate …In a famous publication by Higuchi and Connors, complexes were classified based on the phase solubility profiles derived from the molecular interactions between the host and the guest...In the phase-solubility diagram, the slope was lower than the unit, and the inclusion ratio of BA–β-CD was 1:1. The apparent stability constant (K 1:1) obtained from the Higuchi–Connors formula was 1.3094 × 10 3 mol −1, which showed the existence of favourable interactions. A larger K 1:1 value corresponded to a higher BA solubility ...

The solubilities of voriconazole, ketoconazole, and clotrimazole with and without hydroxybutenyl-β-cyclodextrin (HBenBCD) in aqueous media were examined. The solubility of these antifungal drugs was significantly improved by complexation with HBenBCD. Both the pH and the type of buffer used to adjust the medium pH had a very significant effect on drug solubilities and the apparent binding ...The complexation of diosmin with βCD and HPβCD both indicated an AL type of phase-solubility diagrams, and the apparent stability constants (Kc) was found to be 222.13 and 200.08 M(-1 ...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. Compatibility of host and guest relationship was determined by Higuchi-Connors phase solubility method [16]. Excess amount of drug was added in flask containing different molar ratios of βCD mixed in distilled water. Flasks were placed in water bath (TSSWB15-USA) at 37 ± 2 °C with speed of 100 rpm for 72 h.2.3. Solubility Measurements. Phase-solubility studies of benzoyl metronidazole in aqueous solutions of β-CD were carried out according to the Higuchi-Connors procedure . Various amounts of β-CD were generally dissolved in distilled water, and excess amounts of benzoyl metronidazole were loaded in glass vials. The vials were …

where is glycerin in walmart 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). arkansas river in kansasgreat clipshours In the present study, the solubility of aniracetam alone was 4.53 mg/mL. This is a significant increase from 0.109 mg/mL, which is reported in the literature . The marked increase in apparent solubility may be explained by the limited samples used within the phase solubility analysis at lower HP-β-CD concentrations.Phase solubility.
