A phospholipids-based in situ-forming gel platform (PG) has been developed.
Concurrent delivery of doxorubicin (DOX) and bromotetrandrin (W198).
The adding of oleic acid provides a new strategy to deliver alkaloids via PG.
Achieved sustained drug release both in vitro and in vivo.
Eliminated toxicity and improved antitumor efficacy by reversing the multidrug resistance.
