论文范文:氨甲环酸柔性纳米脂质体凝胶的制作和体外释药分析第一章绪论皮肤色素沉着是临床上皮肤科常见的病症之一,它是由于皮肤受到紫外线照射、炎症刺激等外源性因素和自身疾病引起的内源性因素使大量黑色素非正常聚集于皮肤的不同部位,在皮肤表面呈现出局部颜色变黑,如黑斑息肉综合征、特发性多发性斑状色素沉着、黄褐斑、雀斑、色斑及老年斑等[1]。
皮肤色素沉着类疾病尽管没有疼痛、瘙痒等痛苦,但由于黑色素沉着导致的皮肤肤色不均,进而影响到人们的日常生活。
随着社会的发展,抗色素沉着类疾病引起了人们的关注,从而出现了各式各样祛斑产品和治疗方法[5]。
氨甲环酸(TranexamicAcid,TA)作为一种蛋白酶抑制剂,抑制黑斑部位表皮细胞的机能,改善黑斑部位活性化因子群的活跃状态[6],抑制黑色素的生产而被应用于治疗色素沉着等病症。
目前临床上使用TA 治疗色素沉着疾病多是口服或静脉注射给药,常引起胃肠道刺激等不良反应[7_8]。
经查阅文献的得知:TA作为经皮给药制剂的主要剂型是膏剂,然而因皮肤角质层这一主要的物理屏障,疗效不显著。
近年来,在新技术和新设备不断发展的情况下,关于经皮给药系统在促进药物透皮吸收的方法方面取得了很大的进步[9]。
微乳[iG]、固体脂质纳米粒[11]、脂质体[12]等新型药物载体可与角皮肤质层具有很高的融合性,从而将药物传递到皮肤内部来克服皮肤角质层屏障的影响。
柔性纳米脂质体(Flexible nano-liposomes,FNL)是在脂质体的类脂材料中加入胆酸钠、脱氧胆酸钠等表面活性剂,使其除具有普通脂质体经皮给药系统的优点如生物利用度高、皮肤亲和力好和安全无毒外,还具有高度的变形性、适宜的亲水性和渗透性[13]。
因此能够高效地穿透比自身小数倍的皮肤孔道。
此外,柔性纳米脂质体的结构类似于生物膜结构,与皮肤角质层具有很高的融合性,可以使药物尽可能多地在皮肤的表皮和真皮层内形成一个药物e库,而发挥其缓释效果,使药物能够在局部病变部位持久地起治疗作用。

环孢素A微乳巴布膏眼贴的制备及体外透皮实验陈敏;许丽疆;翁景宁;上官晓辉;严俊;黄金棋;陈丹娜【摘要】背景:免疫性眼病如甲亢性突眼、葡萄膜炎等疾病严重危害患者的眼健康,是眼科的常见病和疑难病,目前最常见的治疗方法为口服激素和免疫抑制剂,疗效不佳、反复发作、预后差同时全身不良反应很大.此类疾病多有淋巴细胞直接或间接参与.尝试把免疫抑制剂制作成巴布膏眼贴,通过局部外用使药物进入体内,利用环孢素A微乳的淋巴靶向性能,使环孢素A作用在睑周淋巴结,从而达到治疗或控制睑周淋巴结参与反应的免疫性眼病.这种方法为局部外用,不用全身用药,针对性强,药物剂量小,如果治疗效果好,可以有效治疗免疫性眼病并规避原有药物全身应用及长期应用的不良反应.目的:制备环孢素A微乳巴布膏眼贴,研究环孢素A微乳巴布膏眼贴体外透皮吸收特性.方法:将环孢素A微乳与聚丙烯酸钠、聚乙烯醇、聚乙烯吡络烷酮、明胶、桃胶、羧甲基纤维素钠、羟丙基纤维素等的水溶性高分子材料混合物以1 mg:1 mL的比例充分混匀,涂布于无纺布上制备成巴布膏.Franz扩散池法测定该巴布膏在ICR小鼠腹部皮肤的通透性.高效液相色谱分析法检测环孢素A浓度,并进行皮肤刺激性和过敏性实验.结果与结论:实验成功制备了粘性适宜、透气透水性能良好、敷贴舒适、无皮肤刺激性和过敏反应的环孢素A微乳巴布膏,环孢素A含量为10 mg/片,质量浓度为1 g/L.环孢素A微乳透皮的浓度随着时间的增加而增加,具有较好的透皮效果.证实将环孢素A微乳制备成巴布膏眼贴是可行的.其在透皮性能、黏附能力、皮肤舒适方面表现良好.%BACKGROUND: Immune eye diseases such as hyperthyroidism exophthalmos and uveitis seriously endanger the eye health of patients, which are common and difficult eye diseases. Current treatments for these diseases include oral administration of hormones and immunosuppressive agents, with poor efficacy, recurrentattacks and poor prognosis. Meanwhile, these treatments can induce systemic adverse reactions. Lymphocytes are directly or indirectly involved in these diseases. Therefore, we try to make papua eye patch carrying immunosuppressant, and deliver the drug through the topical use. Cyclosporin A microemulsion targeting lymphocytes can treat or control palpebral lymph nodes involved in the immune eye diseases. It is a topical method rather than the systemic medication, which is targeted and has small doses of drugs. If possible, this treatment can effectively treat immune eye diseases and avoid systemic drug adverse reactions and long-term adverse reactions induced by original drugs. OBJECTIVE: To study the preparation of cyclosporin A microemulsion papua cream eye patch, and its transdermal absorption characteristics in vitro. METHODS: Cyclosporine A microemulsion was fully mixed with water-soluble polymer materials at a ratio of 1 mg:1 mL, including sodium polyacrylate, polyvinyl alcohol, polyvinylpyrrolidone, gelatin, peach gum, sodium carboxymethylcellulose, hydroxypropylcellulose, and then coated onto the non-woven fabric to prepare Babu cream. Permeability of the Babu cream on the abdominal skin of ICR mice was determined by Franz diffusion cell method. High-performance liquid chromatography was used to detect the concentration of cyclosporine A, and skin irritation and anaphylaxis were also measured. RESULTS AND CONCLUSION: Cyclosporin A microemulsion papua cream eye patch was successfully prepared with appropriate viscosity, good permeability, good permeability, comfortable application, no skin irritation and allergic reaction. The content of cyclosporine A was 10 mg/tablet, andthe concentration was 1 g/L. The concentration of cyclosporine A microemulsion increased with the increase of time, and it had good transdermal effect. This study proved that it is feasible to prepare cyclosporine A microemulsion into papua patch. It has good performance in skin permeability, adhesion and skin comfort.【期刊名称】《中国组织工程研究》【年(卷),期】2018(022)010【总页数】6页(P1553-1558)【关键词】环孢素A微乳;巴布膏;眼贴;工艺研究;体外透皮;免疫性眼病;甲状腺相关眼病;局部给药;生物材料【作者】陈敏;许丽疆;翁景宁;上官晓辉;严俊;黄金棋;陈丹娜【作者单位】莆田学院附属医院眼科,福建省莆田市 351100;莆田学院附属医院眼科,福建省莆田市 351100;福建医科大学附属协和医院眼科,福建省福州市 350000;福建医科大学附属龙岩市第一医院血液风湿科,福建省龙岩市 364000;莆田学院附属医院血液风湿科,福建省莆田市 351100;莆田学院附属医院血液内科,福建省莆田市 351100;厦门大学药学院转化医学中心,福建省厦门市 361102;莆田学院细胞与基因工程研究所,福建省莆田市351100;莆田学院附属医院眼科,福建省莆田市351100【正文语种】中文【中图分类】R3180 引言 Introduction眼部发生一系列的免疫病理变化,引起眼部各种免疫性疾病的发生,统称为免疫性眼病[1]。
