Drug liposome loading
WebEfficient encapsulation of doxorubicin (up to 98%) was obtained concomitantly with liposome preparation avoiding the need for an additional loading step. Parameters such as stock concentration of phospholipid, injection ratio, lipid composition, and drug-to-phospholipid ratio affected the resultant liposome size and magnitude of doxorubicin … WebBackground. Since the first description of the enhanced penetration and retention (EPR) effect in solid cancers, nano-sized drug delivery systems have been the subject for extensive research following their passive accumulation in malignant tissue. 1 Liposome-based drug delivery systems is the most successful EPR-dependent nano-sized drug …
