Development of a dry powder for inhalation of nanoparticles codelivering cisplatin and ABCC3 siRNA in lung cancer

Background: The current study sought to formulate a dry powder inhalant (DPI) for pulmonary delivery of lipopolymeric nanoparticles (LPNs) consisting of cisplatin and siRNA for multidrug-resistant lung cancer. siRNA against ABCC3 gene was used to silence drug efflux promoter. Results & discussion: The formulation was optimized through the quality by design system by nanoparticle size and cisplatin entrapment. The lipid concentration, polymer...
