- Novel alginate gel-core lipid nanocapsules(LNCs) consisting of hydrogel islets in an oil filled matrixand surrounded by a polymeric shell were prepared by hothomogenization and double emulsion method, for codeliveryof both hydrophilic (gemcitabine) and hydrophobic(paclitaxel) anticancer drugs. This system was preparedusing a relatively simple and organic solvent-free methodusing only excipients that are approved by the FDA. Theliquid oil matrix allowed the solubilization and encapsulationof hydrophobic drugs such as paclitaxel, whereasalginate hydrogel islets encapsulated hydrophilic drugssuch as gemcitabine. Alginate gel-core LNCs were characterizedwith respect to particle size, polydispersity index(PDI), morphology, encapsulation efficiency, and in vitrorelease. Dual drug-loaded alginate gel-core LNCs had aparticle size of 171.8 ± 4.1 nm and PDI of 0.201 ± 0.005,respectively, and showed core–shell type spherical morphologywith a smooth surface. In addition, alginate gelcore-LNCs underwent sustained release of both drugs.
These results suggest that alginate gel core-LNCs may beused for co-delivery of hydrophilic (gemcitabine) andhydrophobic (paclitaxel) anticancer drugs.
