Description
技术领域
本发明涉及药物球囊的技术领域,具体涉及一种药物球囊的表面药物涂层的制备方法与应用。
背景技术
近年来,针对血管狭窄的治疗,介入无植入理念越来越受到人们的关注。药物球囊是在球囊扩张术或者成形术等基础上发展起来的治疗性球囊药物释放技术。这种技术是将具有抗再狭窄效果的药物涂覆在球囊表面,扩张手术中药物球囊到达扩张位置扩张血管时,球囊表面的药物也会紧贴在血管壁上从而进入血管中,发挥作用抑制血管的再狭窄。
目前药物球囊的表面药物涂层制备方法较多,但是并非所有的制备方法都能生成稳定有效的药物晶体涂层。当球囊在血管中输送到靶病变位置时,药物涂层会经历血流冲刷过程,这个过程中会出现药物涂层脱落的问题,导致输送至靶病变位置初的药物减少,使药物抑制再狭窄的能力差。
发明内容
因此,本发明要解决的技术问题在于克服现有技术中药物球囊的表面药物涂层在血管中输送到靶病变位置时,药物涂层易脱落,导致输送至靶病变位置初的药物减少,使药物抑制再狭窄的能力差的缺陷。
为此,本发明提供一种药物球囊的表面药物涂层的制备方法,包括如下步骤:
将药物、载体溶解在溶剂中分别配置过饱和溶液和不饱和溶液;
使用过饱和溶液和不饱和溶液依次对球囊进行浸涂和喷涂即可;所述喷涂次数为5-200次。
优选的,所述喷涂次数为10-25次。
可选的,所述浸涂时间为1-30min。
可选的,在浸涂时,边搅拌边进行浸涂,搅拌转速为10-200rps。
可选的,浸涂后将球囊烘干,烘干温度为30-70℃,烘干时间为1-30min。
可选的,烘干后立即将球囊放置于喷涂机上进行喷涂。
可选的,喷涂时喷涂流速为0.5-1mL/h。
可选的,所述药物选自紫杉醇、雷帕霉素、紫杉醇衍生物和雷帕霉素衍生物中的至少一种。
可选的,所述载体选自酚类化合物、吡喃酮类化合物、糖醇类化合物、增塑剂、两亲性聚合物、酰胺类化合物、非离子型表面活性剂、非离子型造影剂中的至少一种,具体的,所述酚类化合物包括茶多酚、生育酚、儿茶酚、没食子儿茶酚、丁香酚、葡萄多酚和/或百里香酚;所述吡喃酮类化合物包括麦芽酚、乙基麦芽酚、香豆素、酒酸、黄酮和/或类黄酮类化合物;所述糖醇类化合物包括麦芽糖醇、木糖醇、山梨糖醇、赤藓糖醇、甘露醇和/或三氯蔗糖;所述增塑剂包括邻苯二甲酸二丁酯(DBP)、邻苯二甲酸二辛酯(DOP)、环氧大豆油、磷酸三甲苯酯、磷酸三苯酯、癸二酸二辛酯和/或氯化石蜡;所述两亲性聚合物包括聚异丁烯-1-聚(N,N-二甲基丙烯酰胺)、聚乙烯亚胺、聚乳酸-羟基乙酸共聚物(PLGA)和/或聚乙烯吡咯烷酮;所述酰胺类化合物包括尿素、N,N-二甲基甲酰胺、N,N二甲基乙酰胺和/或硬脂酸酰胺;所述非离子型表面活性剂包括聚山梨酯、脂肪酸山梨坦、聚氧乙烯脂肪酸酯、聚氧乙烯脂肪醇醚、聚氧乙烯-聚氧乙烯共聚物和/或普郎尼克;所述非离子型造影剂包括碘帕醇、碘海醇和/或碘普罗胺。

对实施例1-9、对比例1-3得到的药物涂层进行晶体尺寸测量,测量方法为:对药物球囊表面的药物涂层进行喷金,接着进行扫描电镜观测,测量晶体尺寸的大小及分布范围,每个实施例、对比例的球囊规格为8.0*40mm,每个实施例、对比例的球囊为10支。测量结果见表1。
表1.晶体尺寸分布测量结果
样品组别 | 尺寸≥8μm(%) | 3μm≤尺寸<8μm(%) | 尺寸<3μm(%) |
实施例1 | 79.8 | 19.0 | 1.2 |
实施例2 | 80.3 | 16.9 | 2.8 |
实施例3 | 76.5 | 20.3 | 3.2 |
实施例4 | 79.1 | 18.8 | 2.1 |
实施例5 | 82.6 | 15.8 | 1.6 |
实施例6 | 81.9 | 15.6 | 2.5 |
实施例7 | 80.1 | 17.1 | 2.8 |
实施例8 | 55.1 | 20.2 | 24.7 |
实施例9 | 46.3 | 19.5 | 34.2 |
对比例1 | 7.1 | 12.3 | 80.6 |
对比例2 | 2.1 | 6.3 | 91.6 |
对比例3 | 10.3 | 22.2 | 67.5 |
由表1可知,本发明获得的药物球囊表面的药物涂层的晶体≥8μm尺寸的晶体占比平均值为73.5%,≥3μm尺寸的晶体占比平均值为91.7%,可见药物球囊表面药物涂层大部分都生成了尺寸大且均匀的晶体,对比例1-3,≥8μm尺寸的晶体占比平均值为6.5%,≥3μm尺寸的晶体占比平均值为20.1%,相对实施例的晶体尺寸较小。尺寸较大的晶体在体内存留代谢的时间更长,更有利于长时间发挥作用抑制管腔的再狭窄,因此,较大尺寸的晶体有利于药物在体内发挥作用的时间更长。
试验例2
分别对实施例1-9、对比例1-3得到的药物球囊表面的药物涂层进行动物体内血液中牢固度测试,测试方法为:取规格为8.0*40mm的球囊,按照实施例1-9、对比例1-3的方法将药物涂层涂覆在球囊表面获得药物球囊,相应的实施例、对比例各获得5个,测试动物为普通的体重为30kg左右的白猪,将药物球囊通过颈动脉入路,到达猪的股动脉位置停止,球囊不打开,停留后取出,停留后即刻、1min、3min取血,测血液中的药物浓度数据,测试方法为:
取50μL血液样本,加入5μg内标药物(内标药物为对应实施例或对比例所用药物),然后加入250μL有机溶剂(有机容积为甲醇和乙腈按照1:1的体积比混合制得)获得混合液,将混合液涡轮1min混匀,在4000r/min条件下离心15min,获取上清液,将上清液使用注射用水稀释两倍,接着使用液相色谱法进行测试。
将药物球囊取出后收集起来,放入5mL棕色容量瓶中,加入5mL甲醇,静置半小时后,得到药物的洗脱溶液。然后使用高效液相色谱仪对洗脱后的溶液进行药物含量测定,并计算残余药量率,残余药量率=1-检测的药物含量/药物球囊名义药物含量,测试结果见表2。
表2.动物体内血液中牢固度测试
由表2可知,本发明获得的药物涂层,在体内血液冲刷过程中,球囊表面残余的药物占比平均值为94.2%,血液中未检测到药物浓度,说明进入血液中的药物极少,即球囊在进入动物体内后受血液冲刷掉落的药物较少,临床安全性较高。对比例中球囊表面药物残余量占比平均值为75.13%,血液在停留完毕后即可时测得的药物浓度最高,平均值约为22.44ng/mL,进入血液中的比例较高,临床安全性较低。
试验例3
分别对实施例1-9、对比例1-3得到的药物球囊表面的药物涂层进行动物体内尿道中牢固度测试,测试方法为:取规格为8.0*40mm的球囊,按照实施例1-9、对比例1-3的方法将药物涂层涂覆在球囊表面获得药物球囊,相应的实施例、对比例各获得5个,测试动物为雄性犬(体重15kg左右的比格犬),将药物球囊通过犬的尿道入路,送达前列腺部位尿道后,球囊不打开,停留1min后取出药物球囊。将扩张后的药物球囊放入5mL棕色容量瓶中,加入5mL甲醇,静置半小时后,得到药物的洗脱溶液。然后使用高效液相色谱仪对洗脱后的溶液进行药物含量测定,并计算残余药量率,残余药量率=1-检测的药物含量/药物球囊名义药物含量,测试结果见表3。
表3.动物体内尿道测试结果
由表3可知,在通过尿道的过程中,本发明的药物球囊表面残余药量占比平均值为96.16%,药物损失较少,药物损失占比平均值为3.84%,而对比例的要球囊表面残余药量占比平均值为80.53%,药物损失占比平均值为19.47%,说明本发明获得的药物球囊的表面药物涂层在通过尿道中的过程中药量损失更小,药物涂层牢固度更好,临床安全性更高。
显然,上述实施例仅仅是为清楚地说明所作的举例,而并非对实施方式的限定。对于所属领域的普通技术人员来说,在上述说明的基础上还可以做出其它不同形式的变化或变动。这里无需也无法对所有的实施方式予以穷举。而由此所引伸出的显而易见的变化或变动仍处于本发明创造的保护范围之中。
