QPAC®25 Polyethylene Carbonate has been studied as a biomaterial for controlled drug delivery applications. The QPAC®25 PEC offers biodegradable properties that make it attractive for this application. Films prepared from PEC have been made with various drugs to study the characteristics and performance of PEC as a potential carrier for controlled drug delivery. Studies have shown that QPAC degrades linearly via enzyme breakdown. There was also a correlation between PEC molecular weight and degradation time. Overall, the studies show that QPAC®25 can be used in controlled drug release applications. Note that QPAC®25 is not FDA registered.
