Salmeterol xinafoate (SAM) and fluticasone propionate (FLU) are one of the drug combinations used together in the treatment of lung diseases such as asthma and chronic obstructive pulmonary disease (COPD). The aim of this study is to investigate the usability of novel dual molecular imprinted nanoparticles (poly(2-hydroxyethyl methacrylate-N-methacryloyl-(L)-alanine-N-methacryloyl-(L)-histidine) [p(HEMA-MAAL-MAH)], abbr. DMIPNPs) as a controlled drug release systems. In this study, SAM and FLU drugs were chosen as model drugs because they are used in the treatment of these diseases. DMIPNPs were prepared by surfactant-free emulsion polymerization method and characterized by scanning electron microscopy (SEM) and fourier transform infrared spectrometer (FTIR). In in vitro drug release experiments, drug release conditions were optimized. SAM and FLU release from DMIPNPs experiments were also performed in the simulated lung fluid (SLF). The amount of released SAM and FLU were found as 4.79 and 5.68 mg/g in the SLF medium at the end of 48 h, respectively. The release kinetics of SAM and FLU from DMIPNPs were calculated in the SLF medium. The release of SAM and FLU was determined to be compatible with the Higuchi release models. According to these results, these DMIPNPs, dual-template molecular imprinted nanoparticles with dual monomers, are promising materials that can be used in the controlled release of two different drugs.
