Abstract
Lipido solidozko nanopartikulak (SLN) farmakoen garraio bideratua lortzeko nanogarraiatzaile interesgarrienetakoak bihurtu dira azken urteotan. Farmako hidrosolugarri nahiz liposolugarriak garraiatzeko gai dira, toxikotasun baxua dute, konposatuaren askapen kontrolatua lortzeko baliagarriak dira eta gorputzeko hainbat barrera zeharkatzeko gai dira. Ezaugarri hauen ondorioz garraiatzen duten farmakoaren bioeskuragarritasuna hobetzen dute terapia askoren efizientzia hobetuz. Lan honetan gantz-azido, soja lezitina eta behazun-gatzez osaturiko 5 konposizio ezberdin sortu eta karakterizatu ditugu. Gure emaitzen arabera konposizioa oso garrantzitsua da partikulen tamaina, homogeneotasun eta egonkortasunerako baina ez da hain garrantzitsua konposatu liposolugarrien barneraketarako.
Solid Lipid Nanoparticles (SLN) have emerged as some of the most promising nanocarriers for controlled drug delivery because of their ability to incorporate hydrophilic and lipophilic drugs, low toxicity, the improvement in controlled drug release, and increased drug diffusion through some biological barriers. Therefore, SLN improve drug solubility and bioavailability improving the efficiency of many treatments. In this work we have tested solid lipid nanoparticles (SLN) composed of long-chain fatty acids, soy bean lecithin, and bile salts. A total of five different systems were prepared and characterized. Our results suggest that SLN composition is essential for particle size, polidispersity and stability but not for drug incorporation efficiency.
