Problems solved by technology

But also there is following shortcoming in this medicine application: (1) chemical property is unstable, and it is highly sensitive to the hydrolysis reaction mediated by serum enzyme, can not effectively increase drug concentration at action site (Pieter A., ​​Pharma.Research.1997, 14( 4): 492-496); (2) There is a certain risk of nephrotoxicity when used in high doses (Taeg H. Drugs of the Future2004, 29(2); 163-177)
