Özet

As research progresses on personalized medicines, it is clear that personalized and flexible formulations can provide effective treatment with reduced side effects especially for diseases like cancer, characteristic of high patient variability. 2D and 3D printers are frequently reported in the literature for the preparation of pharmaceutical products with adjusted dose and selected drug combinations. However, in-depth characterization studies of these formulations are rather limited. In this paper, ex vivo and mechanical characterization studies of antiviral and anticancer drug printed film formulations designed for personalized application were performed. Effects of the printing process with pharmaceutical formulations such as paclitaxel (PCX):cyclodextrin (CD) complex or cidofovir (CDV) encapsulated into poly(ethylene glycol)-polycaprolactone (PEG-PCL) nanoparticles on the films were evaluated through a series of mechanical characterization studies. Inkjet printing process was found to cause no significant change in the thicknesses of the film formulations, while mechanical strength and surface free energy increased and nano-sized voids in the film structure decreased. According to the mechanical characterization data, the unprinted film had maximum force (F-max) value of 15.6 MPa whereas E-ma(x) increased to 43.8 MPa for PCX:CD complex printed film and to 37.7 MPa for the antiviral CDV-PEG-PCL nanoparticle printed film. In the light of ex vivo findings of sheep cervix-uterine tissue, bioadhesive properties of film formulations significantly improved after inkjet printing with different drug formulations. It has also been shown that the anticancer formulation printed on the film was maintained at the cervix tissue surface for > 12 h.
