Secnidazole is a second generation 5-nitroimidazole with high potential for application in anaerobic periodontal infections therapy. In this study, the process of developing drug-loaded films composed oppositely charged chitosan and pectin intra-pocket administration presented. Due to limitations layer-by-layer technique receiving systems type, which resulted from spontaneous crystallization secnidazole at stage drying, new preparation method was developed. For purpose, drug cocrystallization as well two-step drying procedure were implemented order minimize crystals growth during solvent evaporation. Through visual assessment, mechanical strength measurements scanning electron microscopy imaging, most promising secnidazole-chitosan cocrystals-loaded selected further physicochemical (via differential calorimetry, Fourier transform infrared spectroscopy, X-ray powder diffraction, optical microscopy) pharmaceutical (in vitro release, antimicrobial swelling tests) analyses. The impact utilized polymeric composition polyelectrolyte complex structures form (crystalline/amorphous) on performance observed. increased temperature enhanced secnidazole-polymers miscibility, desirable loading improvement also significantly prolonged release artificial saliva.
