Özet

Anal fissure is common and painful disease of anorectum. In this study, microparticles containing nifedipine and lidocaine HCl were prepared by spray drying and applied to bio-degradable and bio-stable tampons. Characterization of microparticles was determined by visual analyses, mass yield, particle size measurement, encapsulation efficiency, drug loading and in vitro drug release. Mass yield was between 5.5 and 45.9%. The particle size was between 15.1 and 26.8 mu m. Encapsulation efficiency were 96.142 +/- 5.931 and 85.571 +/- 3.301; drug loading were 65.261 +/- 3.914% and 37.844 +/- 4.339% of L2 and N1, respectively. Well-separated, mainly spherical microparticles with suitable properties were obtained. Optimum microparticles were applied to tampons. Physical properties and visual characteristics of tampons were investigated before and after binder application. In vitro drug release from tampons were also examined. According to the results, textile-based carrier systems loaded microparticles containing nifedipine and lidocaine HCl will be an effective and promising alternative for current anal fissure treatment.
