Description

一种含珍珠粉治疗小儿湿疹的外用药
技术领域
本发明涉及一种含珍珠粉治疗小儿湿疹的外用药,属于外用药品技术领域。
背景技术
珍珠一直被公认为美容佳品,其美容机理是珍珠中含有各种人体所需的氨基酸和微量元素,珍珠中含有的营养成分与人类肌肤所需养分接近,很容易被人体吸收,具有美白、祛斑的效果。
小儿湿疹是儿科常见病、多发病,多由食物、细菌、真菌变应原及接触性变应原所致,表现为红斑、丘疹、丘疱疹、水疱、渗液、结痂、糜烂,严重影响小儿身体健康,目前常采用皮质类固醇激素治疗,但使用会产生一些副作用,因此,研制一种疗效好、见效快、使用方便的治疗小儿湿疹的新药物,尤其是外用药物,是湿疹患儿的迫切需要。
发明内容
为解决现有技术和实际情况中存在的上述问题,本发明公开了一种含珍珠粉治疗小儿湿疹的外用药,由下列组分按重量百分比组成:水解珍珠粉柔性纳米脂质体27%-38%、葡聚糖15%-20%、呋喃西林0.5%-1%、硝酸咪康唑1%-2.5%、凡士林45%-50%。
优选地,所述组分中的水解珍珠粉柔性纳米脂质体,由大豆卵磷脂、胆酸钠、水解珍珠粉组成,粒径为20nm-50nm。
优选地,所述水解珍珠粉柔性纳米脂质体通过以下制备步骤获得:(1)定量称取豆磷脂、胆酸钠、水解珍珠粉溶于二氯甲烷中;(2)水浴30℃,减压除去二氯甲烷;(3)抽真空保存5h;(4)加入pH7.4的等渗磷酸盐缓冲液,水合后再旋转蒸发仪上去除有机溶剂;(5)将脂质体混悬液置于冰水浴中经探针式间断超声30min后,用0.2μm滤头过滤后得到柔性纳米脂质体。
优选地,所述外用药的制备,通过以下步骤实现:(1)室温下将葡聚糖、呋喃西林、硝酸咪康唑、凡士林混合,并高速搅拌;(2)升温至45℃,加入水解珍珠粉柔性纳米脂质体,搅拌均匀。
