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.
