AB  - In this work, a blend of gelatin A (GA) and polyvinylpyrrolidone (PVP K30) was used for
semi-solid 3D printing of bone scaffold for ibuprofen (IBU) delivery. The cross-linking of the
obtained scaffold was performed with a 1% glutaraldehyde (GTA) solution, followed by
lyophilization. The thermal and mechanical properties, as well as drug release profiles, and drug
kinetics of prepared scaffolds were investigated. The cross-linked and lyophilized scaffold has
shown good thermal stability, mechanical properties, and prolonged release of IBU following the
Fickian diffusion process.
AB  - Nosač za dostavu ibuprofena (IBU) u koštanom tkivu dobijen je metodom 3D štampe ekstruzijom iz paste uz korišćenje smeše polimera želatina A (GA) i polivinilpirolidona (PVP K30). Dobijeni nosač je umrežen sa 1% rastvorom glutaraldehida (GTA), nakon čega je usledio proces liofilizacije uzoraka. Ispitivana su mehanička i termička svojstva, profili i kinetika oslobađanja ibuprofena iz dobijenih nosača. Umrežen i liofilizovan nosač pokazao je dobru termičku stabilnost i mehanička svojstva, kao i produženo oslobađanje IBU-a koje prati kinetiku po Fikovom zakonu difuzije.

AB  - Gelatin-polyvinylpyrrolidone (PVP) and gelatin-poly(vinyl alcohol) (PVA) mucoadhesive buccal films loaded with propranolol hydrochloride (PRH) were prepared by semi-solid extrusion 3D printing. The aim of this study was to evaluate the effects of the synthetic polymers PVP and PVA on thermal and mechanical properties and drug release profiles of gelatin-based films. The Fourier-transform infrared spectroscopy showed that hydrogen bonding between gelatin and PVP formed during printing. In the other blend, neither the esterification of PVA nor gelatin occurred. Differential scanning calorimetry revealed the presence of partial helical structures. In line with these results, the mechanical properties and drug release profiles were different for each blend. Formulation with gelatin-PVP and PRH showed higher tensile strength, hardness, and adhesive strength but slower drug release than formulation with gelatin-PVA and PRH. The in silico population simulations indicated increased drug bioavailability and decreased inter-individual variations in the resulting pharmacokinetic profiles compared to immediate-release tablets. Moreover, the simulation results suggested that reduced PRH daily dosing can be achieved with prolonged-release buccal films, which improves patient compliance.

AB  - This study processes and characterizes propranolol hydrochloride/gelatin mucoadhesivebuccal films.  Two types of gelatin are used:  Gelatin from porcine skin, type A (GA), and gelatinfrom bovine skin (GB). The influence of gelatin type on mechanical, mucoadhesive, and biopharma-ceutical characteristics of buccal films is evaluated. Fourier-Transfer infrared spectroscopy (FTIR)and differential scanning calorimetry (DSC) analysis show that GA with propranolol hydrochloride(PRH) in the film (GAP) formed a physical mixture, whereas GB with PRH (GBP) form a compound-complex. Results of mechanical testing (tensile test, hardness) revealed that GAP films exhibit higherelastic modulus, tensile strength, and hardness.  A mucoahesion test shows that GBP has higheradhesion strength, while GAP shows higher work of adhesion. Bothin vitrorelease study and insilico simulation indicated that processed films can provide effective drug transport through thebuccal mucosa. In silico simulation shows improved bioavailability from buccal films, in comparisonto the immediate-release tablets—indicating that the therapeutic drug dose can be markedly reduced.

AB  - The preparation and characterization of films and nanofibers with carvedilol as a poorly water-soluble drug in poly (ethylene oxide) (PEO) polymer were investigated. Films are prepared by solution casting method, and nanofibers by electrospinning from a polymer solution. Water and mixture of ethanol and water were used as solvents. FT-IR analysis of the samples showed that there was no interaction between the polymer and the drug substance. DSC analysis revealed that carvedilol was dissolved in the polymer and influenced the degree of crystallinity of PEO. Carvedilol release rate for all of the formulations was increased in comparison with pure carvedilol. Significant differences in the rate of release of carvedilol from the films and nanofibers were observed. Field Emission Scanning Electron Microscope (FESEM) images of the obtained fiber was revealed the dependence of the fiber diameter of formulation and electrospinning process parameters, and consequently influence the amount and distribution of carvedilol in the encapsulated fibers.
