Disulfide Bridged Nanoparticles of Thiolated Sodium Alginate and Eudragit RS100 for Oral Delivery of Paclitaxel: In Vitro and In Vivo Evaluation.

ABSTRACT: Most biopharmaceutics classification system (BCS) class IV drugs have limited oral bioavailability due to poor solubility and poorer permeability. This work aims to investigate the possibility of utilizing disulfide bridged nanoparticles to improve BCS IV drug solubility and oral absorption. Disulfide bridged nanoparticles were made using thiolated sodium alginate (TSA) and thiolated eudragit RS100 (TERS100). This study used paclitaxel (PTL) as a model drug to create PTL-loaded nanoparticles using the air oxidation approach. PTL-loaded nanoparticles boosted the solubility of PTL by over 11 times (∼59 μg/mL). The nanoparticles had particle sizes of 103 nm, polydispersity indices of 0.034, and zeta potentials of -21 mV, respectively. Nanoparticles demonstrated 75.34% and 89.18% entrapment an
