Cyclodextrin Inclusion Complex

Nifedipine is widely used for managing hypertension. The challenges of developing nifedipine oral preparation are its low solubility and unpleasant taste. The purpose of developing the Oral Disintegrating Tablet (ODT) dosage form from the Nifedipine-β-cyclodextrin inclusion complex is to increase the solubility of nifedipine and mask the unpleasant taste of the drug. Specific target: use of a superdisintegrant combination to increase the solubility of nifedipine and mask the bitter taste. The method used in the formation of Nifedipine inclusion complex with β-cyclodextrin was kneading method. Making ODT was done by direct pressing method. Characterization of nifedipine-β-cyclodextrin inclusion complex was analyzed by FTIR and DSC. ODT was tested for the physical properties of the tablet and its solution. Test results for ODT physical properties were analyzed and compared with the literature. Data obtained from the dissolution test results calculated the concentration of the active substance dissolved at 20 minutes (Q20). The results showed that the formation of the Nifedipine-β-cyclodextrin inclusion complex increased solubility and masked the bitter taste. The combination of superdisintegrant Ac-Di-Sol-Crosspovidon accelerated the disintegration and dissolution time and improve the taste of Nifedipine ODT.

Cyclodextrin Inclusion Complex

Imidacloprid-β-cyclodextrin (IMI-β-CD) inclusion complex was synthesized and effectively incorporated into filament yarns of polypropylene. The physical and thermal properties of IMI-β-CD inclusion complex were determined by Fourier transform infrared spectroscopy, thermogravimetric analysis, and differential scanning calorimetry. According to the results, formation of the inclusion complex was achieved along with enhanced thermal stability. The release profile of imidacloprid was monitored by high-performance chromatography measurements. Dissolution time of the IMI-β-CD inclusion complex was increased to 5 times that of the neat imidacloprid (from 9 h to 48 h). Poylpropylene filament yarns containing 3 wt.% IMI-β-CD inclusion complex released 84 wt.% of IMI within 21 days.

Co Precipitation

Racemic ketoprofen (KP) and β-cyclodextrin (β-CD) powder samples from co-precipitation (1), evaporation (2), and heating-under-reflux (3) were analysed using X-ray techniques and nuclear magnetic resonance (NMR) spectroscopy. On the basis of NMR studies carried out in an aqueous solution, it was found that in the samples obtained by methods 1 and 2, there were large excesses of β-CD in relation to KP, 10 and 75 times, respectively, while the sample obtained by method 3 contained equimolar amounts of β-CD and KP. NMR results indicated that KP/β-CD inclusion complexes were formed and the estimated binding constants were approximately 2400 M−1, showing that KP is quite strongly associated with β-CD. On the other hand, the X-ray single-crystal technique in the solid state revealed that the (S)-KP/β-CD inclusion complex with a stoichiometry of 2:2 was obtained as a result of heating-under-reflux, for which the crystal and molecular structure were examined. Among the methods used for the preparation of the KP/β-CD complex, only method 3 is suitable.
