WebIt is a major active metabolite of risperidone approved for the treatment of schizophrenia in adults. The inclusion complexes were prepared in 1:1 (PALI: HP-β-CD) molar ratio. Phase solubility studies were performed according to Higuchi Connors method to determine the optimum conditions for the complexation. Webdiagram of Higuchi & Connors and by a method described by Filipović-Grcić J et al..1 with minor modifications to improve the HA water solubility. This new method improved percentage of inclusion reaching the maximum percentage of inclusion (91.52±0.92%) using by Filipović-Grcić J et al..1 which was 25%. The complex HA/HPβCD was characterized

WebThe Higuchi窶鼎onnors phase-solubility method8)is very often used to determine K 1:1 , as a part of a formulation study. This method is based on the effect of a complex forming lig- and, e.g.CD, on the solubility of the drug. The intrinsic solu- bility (S 0 ) and the slope of the phase-solubility diagram are then used to calculate K 1:1 WebCyclodextrins (CDs), a group of oligosaccharides formed by glucose units bound together in a ring, show a promising ability to form complexes with drug molecules and improve their …
WebMay 20, 2016 · Here, the key to solubilisation is identified as the formation of inclusion complexes with the drug molecule. If inclusion complexation were the only contribution to drug solubility, it would increase linearly with CD concentration (as per the Higuchi–Connors model); this is because inclusion complexation is a 1 : 1 stoichiometric process. WebAug 28, 2024 · The Higuchi-Connors method was used to corroborate it. The Benesi-Hildebrand method fixes ligand concentration (cyclodextrin) to different solutions with variable amounts of the substrate, from one to five mM. The absorbance of the free ligand is measured, and then subtracted from the rest of the solution's absorbances levels (ΔA).
