Dhanoa, M.S. The dissolution rate of CUR was positively improved as the amount of HPβCD in SDs increased. The solvent was evaporated using a rotary vacuum evaporator (EYELA, Tokyo Rikakikai Co. Ltd., Tokyo, Japan) at 40 °C at a speed of 50 rpm. PXRD were performed using a diffractometer (RINT 2000, Rigaku Co. Ltd., Tokyo, Japan) using Cu Kα radiation, an X-ray tube voltage of 40 kV, and an X-ray tube current of 40 mA. The combined effect of ionization and complexation on drug solubility has been derived similarly to the above scenario of solubilization by ionization and micellization. All reagents were of analytical grade. Drugs must possess some solubility in water to be therapeutically effective after oral or topical administration to the eye, and drugs must be soluble to be formulated as aqueous solutions for, for example, parenteral delivery. ; Quintans-Júnior, L.J. ... Complexation of drugs with. The defined weights of CUR and HPβCD were mixed in a 30 mL glass sample tube with a vortex mixer for 60 sec to obtain the physical mixtures (PMs). prodrug with higher intrinsic solubility than the parent drug). ; Silva, G.F.; Olivera, J.F. Jantarat, C.; Sirathanarun, P.; Ratanapongsai, S.; Watcharakan, P.; Sunyapong, S.; Wadu, A.

Ionization of a drug molecule sometimes increases the complexation efficiency by increasing the intrinsic solubility of the drug. An endothermic peak at 222 °C was observed in the DSC curve of HPβCD, thus indicating its decomposition peak (, The dissolution profiles of CUR crystals and SDs that were prepared by the grinding, FD, and CSE methods are depicted over a 120 min period (, According to the dissolution profiles of PMs (, The DEs (%) over 120 min of CUR crystals and SDs prepared using the grinding, FD, and CSE methods are displayed in. A variety of methods can be applied to enhance aqueous solubility of poorly soluble drugs one of which is the usage of solubilizing complexing agents. Solid dispersion-based spray-drying improves solubility and mitigates beany flavour of pea protein isolate. Comparative curcumin solubility enhancement study of β-cyclodextrin and its derivative hydroxypropyl-β-cyclodextrin. Cyclodextrins (CDs) and their derivatives significantly increase drug solubility by forming drug/CD complexes known as solid dispersions (SDs), which consist of an inclusion complex (IC), where the drug is entrapped within the CD cavity, and a non-IC. The SD system consisting of CUR and HPβCD significantly increased the drug solubility compared to ICs. This type of solubility is generally attributed to a change in the solute-solvent interaction, such as ionization of guest molecules (Evrard et al., 2002). The drug was well dispersed within HPβCD in GMs and CSEs, suggesting the formation of hydrogen bonds between CUR and HPβCD, whereas the dispersed behavior of FDs was similar to that of PMs. ; Le, T.C. ; Lennernäs, H.; Shah, V.P. Loftsson, T.; Másson, M.; Brewster, M.E. Coordination complexes consist of drugs that act as complexing agents (i.e. ; Stamboliyska, B.A. The defined weights of HPβCD and CUR were dissolved in 50 mL MeOH. Enhanced solubility of alkaloid by complexation with polycarboxylic materials for controlled release formulations: Case of Peschiera fuchsiaefolia. The ability to increase aqueous solubility can thus be a valuable aid to increasing efficiency and/or reducing side effects for drugs. Once CUR was added to the solution, the dispersions were stirred at 500 rpm for 15 min at 30 °C. The stroke immersion for 5 min in liquid nitrogen and the grinding was repeated twice, thus corresponding to 30 min of grinding time. Spectrofluorimetric determination of stoichiometry and association constants of the complexes of harmane and harmine with β-cyclodextrin and chemically modified β-cyclodextrins. Study of the solubility, antioxidant activity and structure of inclusion complex of vanillin with β-cyclodextrin. substrates). Narayanacharyulu, R.; Krishna, S.C.; Mudit, D. Design and development of sustained release tablets using solid dispersion of beclomethasone dipropionate. In aqueous media, drug molecules of appropriate size and structure will enter into the central cavity of CD molecules to form water-soluble complexes and, frequently, enhanced total drug solubility is observed. ; Souza, J.C.C. Finally, enhanced complexation efficacy can be obtained by forming a more water-soluble drug derivative of a water- insoluble drug (i.e. Akbik, D.; Ghadiri, M.; Chrzanowski, W.; Rohadizadeh, R. Curcumin as a wound healing agent. We use cookies on our website to ensure you get the best experience. ; Markl, D.; Ward, A.; Walton, K.; Blunt, L.; Korde, S.; Pagire, S.K.

Samples were weighed (3~5 mg) and sealed in aluminum pans under N, The dissolution profiles of CUR in the samples were evaluated using the dissolution apparatus as specified in the 17th Japanese Pharmacopoeia [, Khan and Rhodes suggested DE as a suitable parameter for the evaluation of in vitro dissolution [, Although the CUR SD formation can increase the solubility of drug, the DE hardly attains 100%. ; Kim, J.K.; Park, J.S.

The CUR content was analyzed using ultraviolet (UV)–visible spectroscopy at 432 nm (Shimadzu 1800 UV–visible spectrophotometer, Shimadzu Co. Ltd., Kyoto, Japan). The statements, opinions and data contained in the journals are solely Because the CSE method was considered to form entirely ICs with the molar ratio of CUR:HPβCD = 1:2, the SD of CSE12 consisted of 1:2 ICs only. ; Hammad, M.A. Self-association and cyclodextrin solubilization of drugs.

Then, the samples were placed in a vacuum dryer (vacuum sample drying oven HD-120, Ishii Laboratory Works Co. Ltd., Osaka, Japan) for 24 h to completely evaporate the solvent. Please let us know what you think of our products and services. In SDs, the melting temperature of CUR was in an increased order of CUR in 1:2 ICs, CUR in 1:1 ICs, and CUR crystals. Following this, the ground mixtures were passed through a 36-mesh sieve and stored in a desiccator until further evaluation.
