PREPARATION AND CHARACTERIZATION OF THE EMAMECTIN BENZOATE/HYDROXYPROPYL-B-CYCLODEXTRIN INCLUSION COMPLEX
The objective of this study was to prepare an inclusion complex of the insecticide emamectin benzoate (EB) with hydroxypropyl-β-cyclodextrin (HO-β-CD) by co-evaporation and spray drying methods. The complexation of both compounds was evaluated on the aqueous and solid state using p...

| Sumario: | The objective of this study was to prepare an inclusion complex of the insecticide emamectin benzoate (EB) with hydroxypropyl-β-cyclodextrin (HO-β-CD) by co-evaporation and spray drying methods. The complexation of both compounds was evaluated on the aqueous and solid state using phase solubility diagrams, differential scanning calorimetry (DSC), X-Ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR) and scanning electron microscopy (SEM). The aqueous solubility of the inclusion complexes at pH 8 had a 2-fold increase respect to the drug alone and dissolution profiles showed a rise in the dissolution rate. These results suggest that the use of HO-β-CD could be an interesting alternative to enhance the bioavailability of EB in salmons. |
