Abstract:

AIM: The use of inhalable nanomedicines can overcome the Enhanced permeation and retention effect (EPR)-associated drawbacks in lung cancer therapy via systemic nanomedicines.

METHODS: We developed a lactoferrin-chondroitin sulfate nanocomplex for the co-delivery of doxorubicin and ellagic acid nanocrystals to lung cancer cells. Then, the nanocomplex was converted into inhalable nanocomposites via spray drying.

RESULTS: The resulting 192.3 nm nanocomplex exhibited a sequential faster release of ellagic acid, followed by doxorubicin. Furthermore, the nanocomplex demonstrated superior cytotoxicity and internalization into A549 lung cancer cells mediated via Tf and CD44 receptors. The inhalable nanocomposites exhibited deep lung deposition (89.58% fine particle fraction [FPF]) with powerful antitumor efficacy in lung cancer bearing mice.

CONCLUSION: Overall, inhalable lactoferrin-chondroitin sulfate nanocomposites would be a promising carrier for targeted drug delivery to lung cancer.
