The purpose of this study was to investigate the effect of sodium carboxymethylcellulose (Na-CMC) and fucidic acid on the gel characterization for the development of sodium fucidate-loaded wound dressing. The cross-linked hydrogel films were prepared with polyvinyl alcohol (PVA) and sodium carboxymethylcellulose (Na-CMC) using the freeze-thawing method. Their gel properties such as gel fraction, swelling, water vapor transmission test, morphology, tensile strength and thermal property were investigated. In vitro protein adsorption test and release were performed. Na-CMC decreased the gel fraction and tensile strength of the hydrogels, but increased the swelling ability, water vapor transmission rate, elasticity and porosity of hydrogels. Thus, the wound dressing developed with PVA and Na-CMC was more swellable, flexible and elastic than that with only PVA because of its cross-linking interaction with PVA. However, the drug had a negative effect on the gel properties of hydrogels but there were no significant differences. In particular, the hydrogel composed of 2.5% PVA, 1.125% Na-CMC and 0.2% drug might give an adequate level of moisture and build up the exudates on the wound area. Thus, this sodium fucidate-loaded hydrogel could be a potential candidate for wound dressing with excellent forming.
本研究旨在探讨羧甲基纤维素钠(Na-CMC)和富马酸对开发载夫西地酸的伤口敷料的凝胶特性的影响。采用冻融法制备了聚乙烯醇(PVA)和羧甲基纤维素钠(Na-CMC)的交联水凝胶薄膜。研究了其凝胶特性,如凝胶分数、溶胀性、水蒸气透过试验、形态、拉伸强度和热性能。进行了体外蛋白质吸附试验和释放。Na-CMC 降低了水凝胶的凝胶分数和拉伸强度,但增加了水凝胶的溶胀能力、水蒸气透过率、弹性和孔隙率。因此,与仅含 PVA 的水凝胶相比,含 PVA 和 Na-CMC 的伤口敷料具有更好的溶胀性、柔韧性和弹性,因为它与 PVA 具有交联相互作用。然而,药物对水凝胶的凝胶性能有负面影响,但没有显著差异。特别是由 2.5% PVA、1.125% Na-CMC 和 0.2% 药物组成的水凝胶可能会提供足够的水分,并在伤口区域积聚渗出物。因此,这种载夫西地酸的水凝胶可能是一种具有优异成型性的潜在伤口敷料候选材料。
