The jar was immersed in liquid nitrogen for 5 min and then the material was ground using the MM400 for 15 min at 30 Hz. ; Mourtzinos, I.; Yannakopoulou, K.; Andrikopoulos, N.K. Samples were stored in a desiccator until further evaluation. The dissolution rate of CUR was positively improved as the amount of HPβCD in SDs increased. Inclusion complex of (−)-linalool and β-cyclodextrin. HPβCD was purchased from Nihon Shokuhin Kako Co. Ltd. (Tokyo, Japan). 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. Problem of solubility can be solved by different approaches. The statements, opinions and data contained in the journal, © 1996-2020 MDPI (Basel, Switzerland) unless otherwise stated. ; Castillo, B.; Martín, M.A. When the amount of HPβCD increased (in CSE14 and CSE18), the SD system was obtained and the DEs of CSE14 and CSE18 were 31.27 and 52.21%, respectively. Prepared samples containing 5 mg CUR were dispersed in 10 mL DW in 20 mL L-tubes. The second or higher order complex of CUR-HPβCD indicated the co-existence of ICs and non-ICs, known as the SD system. ; Stamboliyska, B.A. Narayanacharyulu, R.; Krishna, S.C.; Mudit, D.

Solubility modelling and thermodynamic aspect of d-aspartic acid in aqueous co-solvent mixtures of N-methyl-2-pyrrolidone, N,N-dimethylformamide, dimethyl sulfoxide and 1,4-dioxane. Enhanced solubility of alkaloid by complexation with polycarboxylic materials for controlled release formulations: Case of Peschiera fuchsiaefolia. The definite weights of HPβCD were dissolved in 20 mL DW with a small amount of 10% ammonia solution (pH = 10). 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. N.N.S.M. The samples were then dried using a freeze-dryer (EYELA DFU-2110, Tokyo Rikakikai Co, Ltd., Tokyo, Japan) and passed through a 36-mesh sieve. An Experiment Using “Memes” in Pharmacy Education, https://www.applichem.com/en/shop/product-detail/as/2-hydroxypropyl-beta-cyclodextrin/, http://creativecommons.org/licenses/by/4.0/. Examples of coordination complexes are some water-soluble tetracycline-metal ion complexes. The SD system consisting of CUR and HPβCD significantly increased the drug solubility compared to ICs. Alshafiee, M.; Aljammal, M.K. The scanning range was set as 4000–400 cm, DSC measurements were carried out using the DSC-60 Plus Differential Scanning Calorimeter (Shimadzu Co. Ltd., Kyoto, Japan), associated with the TA-60WS thermal analyzer (Shimadzu Co. Ltd., Kyoto, Japan) and the FC-60A flow controller (Shimadzu Co. Ltd., Kyoto, Japan). Once complexation occurs, the physical and chemical properties of the complexing species are altered. Overview of the manufacturing methods of solid dispersion technology for improving the solubility of poorly water-soluble drugs and application to anticancer drugs. ; Matos, I.L. Preparation and study the 1:2 inclusion complex of carvedilol with β-cyclodextrin. This work was developed with the objective of studying the complexation of ABZ with E-CD in Here, the SDs of curcumin (CUR) and hydroxypropyl-β-cyclodextrin (HPβCD) were prepared using the grinding, freeze-drying (FD), and common solvent evaporation (CSE) methods and were physicochemically characterized using solubility, powder X-ray diffraction, Fourier transform infrared, differential scanning calorimetry, and dissolution studies. ; David, S.K. There are numerous types of complexes and some are more water-soluble than others. 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. Next, the dispersions were sonicated for 4 h at a temperature under 30 °C.

Carrageenan as a Dissolution Enhancer of Poorly Soluble Drugs. The first author is grateful to the Ministry of Education, Culture, Sport, Science and Technology Japan for a PhD scholarship. Wen, X.; Tan, F.; Jing, Z.; Liu, Z. prodrug with higher intrinsic solubility than the parent drug). Each PM (500 mg) was transferred to a 5 mL stainless steel jar on a mixer mill (MM400, Retsch, Haan, Germany) containing a ball (stainless steel, Φ7 mm). The total transformation into the amorphous phase of CUR was observed in GMs and in CSE12, CSE14, and CSE18. ; Rhodes, C.T. Solubility of drug can be increase by increasing of dissolution rate. Maurice, R.E. Higuchi, T.; Connors, K.A. the drug) and a small (e.g., caffeine) or a large (e.g., polyvinylpyrrolidone) ligand. Complexation with CDs by different methods like physical mixing, melting, kneding, spray drying, freeze drying, co-evaporation has been reported to enhance the solubility, dissolution rate and bioavability of poorly water soluble drugs. Jahed, V.; Zarrabi, A.; Bordbar, A.; Hafezi, M.S. Coordination complexes consist of drugs that act as complexing agents (i.e. ; Lennernäs, H.; Shah, V.P. When comparing the soluble drug amount with CUR crystals, the solubility of SDs was enhanced by up to 299-, 180-, and 489-fold, corresponding to the GMs, FDs, and CSEs, respectively. Sammour, O.A. Konan, K.V. In other words, there was no CUR crystal, “empty” HPβCD, and 1:1 IC in the CSE12 whose DE was 10%. Sun, Y.; Du, L.; Liu, Y.; Li, X.; Li, M.; Jin, Y.; Qian, X.
