Mucoadhesive Solid Lipid Microparticles (SLM) for sustained release of corticosteroids to the lungs
2016
Pulmonary delivery is the preferred route of drug administration in the treatment of many respiratory disease, such as asthma and chronic obstructive pulmonary disease (COPD). Over the years, several kinds of carriers have been studied for sustained release of corticosteroids and bronchodilators to the lungs. Solid Lipid Microparticles (SLM) due to their biocompatibility and size (3-5 µm) can reach the bronchial epithelium directly, circumvent first pass metabolism and avoid systemic toxicity [1,2]. In this work we describe the preparation and the characterization of two different systems subjected to chitosan and alginate coating for sustained release of fluticasone propionate (FP) into th…
Surfactant effect on the physicochemical characteristics of cationic solid lipid nanoparticles
2016
Solid lipid nanoparticles (SLNs) may be considered as a new approach for therapeutics for many diseases. In addition to drug delivery, their use as non-viral vectors for gene delivery can be obtained by including cationic lipids, which provide a positive surface potential that favors binding to the nucleic acids as DNA, siRNA, miRNA, etc. In fact, the addition of cationic surfactants is indispensable for obtaining nanoparticles with surface positive charge. In this study, three different cationic lipids (dioctadecyl dimethyl ammonium bromide, cetyltrimethyl ammonium bromide, cetylpyridinium chloride) and Brij 76 as nonionic surfactant were employed to formulate Precirol ATO 5 based cSLN usi…
