Paclitaxel delivery from PLGA foams for controlled release in post-surgical chemotherapy against glioblastoma multiforme.

Paclitaxel loaded biodegradable poly-(DL-lactic-co-glycolic) acid (PLGA) foams with microporous matrix were fabricated by a novel pressure quenching approach to provide a sustained paclitaxel release. The foams with micropores provided increased surface area to volume ratio and were also implantable for post-surgical chemotherapy applications. The two formulations 5% (w/w) paclitaxel loaded PLGA 85:15 foam (F1) and 10% (w/w) paclitaxel loaded PLGA 50:50 foam (F2), were evaluated in vitro and in vivo.
