Preparation and characterization of ceftiofur sodium-chitosan nanoparticles
摘要
Abstract
To prolong the action time of ceftiofur sodium, ceftiofur sodium-chitosan nanoparticle(CNP) were prepared by ionic crosslinking method. Morphology, particle size and distribution, encapsulation efficiency and drug loading rate were investigated. In result, the appearance of prepared CNP was regular with the diameter being of 179.4±39.5 nm. The encapsulation efficiency and drug-loading rate were 84.31% ±2.53 % and 6.69 %±0.18 % respectively. The in vitro release experiment showed that the ceftiofur sodium was released above 90% at 4 h post-treatment,meanwhile only 60% was released from CNP. In conclusion, the CNP preparation procedure is feasible and CNP have obvious sustained-release effect.关键词
