Abstract:

BACKGROUND: Modified medical adhesives with α-cyanoacrylate as the main component can produce a large adhesive strength in a moist environment, such as carrying different types of drugs, achieving a sustained release of drug and inducing the creeping substitution of new bone tissue.
OBJECTIVE: To analyze the physical and chemical characteristics of cyanoacrylate-nano drug delivery system so as to clarify its clinical prospect in the future and problems to be solved.
METHODS: A computer-based online search of PubMed, CNKI databases was performed for articles published from January 2004 to October 2012 using the key words of “cyanoacrylate; nanoparticle drug delivery system; targeted therapy” in English and Chinese, respectively. Articles related to cyanoacrylate and nano-drugs bone targeted therapy were included.
RESULTS AND CONCLUSION: In view of cyanoacrylate and its derivatives can be bonded quickly in the bone marrow cavity under moist conditions, have larger strength and can be degraded, cyanoacrylate-nano drug is used for bone targeted therapy. The FDA has upgraded cyanoacrylate applicable level from Class Ⅲ to Class Ⅱ. Future issues could make full use of the advantages of nano-drug targeted therapy, to achieve high drug load and controlled drug release; carry out interdisciplinary research to improve bonding strength, biomechanical strength and elastic modulus of bone-prosthesis interface; develop composite biomaterials thereby to improve the deficiency of single materials in performance. Compound nano-drug targeted therapy will be a great potential way to the treatment of bone tumors, bone tuberculosis and osteomyelitis.
