Preparation and characterization of hydroxyapatite-coated iron oxide particles by spray-drying technique.
Magnetic particles of iron oxide have been increasingly used in medical diagnosis by magnetic resonance imaging and in cancer therapies involving targeted drug delivery and magnetic hyperthermia. In this study we report the preparation and characterization of iron oxide particles coated with bioceramic hydroxyapatite by spray-drying. The iron oxide magnetic particles (IOMP) were coated with hyd...
متن کاملPreparation and in vivo evaluation of piroxicam-loaded gelatin microcapsule by spray drying technique.
To develop a piroxicam-loaded gelatin microcapsule with enhanced bioavailability, a gelatin microcapsule encapsulated ethanol and piroxicam has been formulated by using gelatin as a water-soluble polymer shell. The aqueous solubility and bioavailability of piroxicam in piroxicam-loaded microcapsule in rats were then evaluated compared to piroxicam powder. The piroxicam-loaded gelatin microcapsu...
متن کاملPreparation of redispersible liposomal dry powder using an ultrasonic spray freeze-drying technique for transdermal delivery of human epithelial growth factor
In this work, an ultrasonic spray freeze-drying (USFD) technique was used to prepare a stable liposomal dry powder for transdermal delivery of recombinant human epithelial growth factor (rhEGF). Morphology, particle size, entrapment efficiency, in vitro release, and skin permeability were systematically compared between rhEGF liposomal dry powder prepared using USFD and that prepared using a co...
متن کاملTaste masking of roxithromycin by spray drying technique.
The spray drying technique was used to obtain the roxithromycin containing microcapsules with high taste masking efficiency. Eudragit L30D-55 was chosen as a barrier coating. The taste was evaluated by an electronic tongue, and taste-masking effect in water lasted at least several dozen hours.
متن کاملProperties of Nanostructured Hydroxyapatite Prepared by a Spray Drying Technique
In previous studies nano sized hydroxyapatite (HA) particles were prepared by solgel or precipitation methods, in which the products were washed by aqueous or non-aqueous liquids to remove impurities or undesired components. The washing is know to modify the surfaces of the cystalline particles. This study evaluated properties of nano HA materials prepared by a spray drying method in which the ...
