Fenofibrate is used to treat dyslipidemia, a health condition that could lead to cardiovascular diseases. Fenofibrate is classified as a class II drug by the Biopharmaceutical Classification System due to its high lipophilicity and low solubility in water. The purpose of this work was to enhance the dissolution characteristics of fenofibrate by incorporating it into 2-hydroxylpropyl-β-cyclodextrin fibers for the first time. Single-needle electrospinning was used to prepare the fenofibrate-loaded cyclodextrin fibers. The drug loading was optimized to fulfill the electrospinning conditions and was determined to be a 1:4 drug:cyclodextrin molar ratio. We found dimethylformamide a suitable solvent and were able to prepare bead-free fenofibrate-loaded 2-hydroxylpropyl-β-cyclodextrin fibers with an average diameter of 2.65 ± 0.82 μm. Drug loading was determined to be close to the theoretical value, 97.2%, with the aid of ultraviolet spectroscopy. Differential scanning calorimetry and Fourier transform infrared spectroscopy were used to track the crystalline to amorphous transition of fenofibrate through fiber formation. The dissolution results indicated a 60-fold increase in fenofibrate from the prepared fibers with respect to the micronized active ingredient.
非诺贝特用于治疗血脂异常,这是一种可能导致心血管疾病的健康状况。由于其高亲脂性和在水中的低溶解度,非诺贝特在生物药剂学分类系统中被归类为II类药物。这项工作的目的是首次将非诺贝特掺入2-羟丙基-β-环糊精纤维中,以提高其溶解特性。采用单针静电纺丝法制备了载非诺贝特的环糊精纤维。对载药量进行了优化以满足静电纺丝条件,确定药物与环糊精的摩尔比为1:4。我们发现二甲基甲酰胺是一种合适的溶剂,并且能够制备出平均直径为2.65±0.82μm的无珠载非诺贝特2-羟丙基-β-环糊精纤维。借助紫外光谱法测定载药量接近理论值,为97.2%。采用差示扫描量热法和傅里叶变换红外光谱法跟踪非诺贝特通过纤维形成从结晶态到无定形态的转变。溶解结果表明,相对于微粉化活性成分,制备的纤维中非诺贝特的溶出度提高了60倍。
