Description
技术领域
本发明属于中医药技术领域,具体涉及一种治疗眼睑湿疹的药物。
背景技术
眼睑湿疹(palpebral ecgema)是一种过敏性皮肤病,分急性、亚急性和慢性三种表现。可单发于眼睑部,亦可为全身、面部湿疹的一部分。其中急性症状表现为:①睑部有明显的刺痒感和烧灼感;②眼睑皮肤红肿,出现红斑、丘疹、水疱(如有继发感染则为脓疱、溃疡)、结盟痂等;③血嗜酸粒细胞增多。慢性症状:湿疹长期不愈,眼睑皮肤粗糙呈鳞屑样,组织肥厚。一般具有一定程度的规律性。主觉症状:在与致敏物质的接触后出现,病变部位热奇痒感。病变表现:起初眼睑皮肤红肿,局部见大量血疹、水泡、糜烂、结痂。当继发感染时则形成脓泡。脱痂而痊愈。范围亦可扩大至面部、额部等。但亦可由急性演变为亚急性和慢性。睑部皮肤粗糙肥厚、呈苔癣状,表面有鳞屑脱落,亦可有色素沉着等。倘若继续接触致敏物质或药物,尚可发生渗出性结膜炎、角膜表层浸润、水肿等并发症。
中医学认为本病系风湿热邪客于泡睑,或久病耗血、生风化燥所致。中医疗法:内服活瘀凉血、清热、除湿、解毒之药。

具体实施方式
下面结合具体实施例对本发明作进一步说明,但并不限制本发明。
实施例1、本发明中药口服液的制备
为了给急慢性毒性试验和临床试验提供药品,同时验证本发明制备工艺,按本发明中药配方实践生产中药口服液,所述口服液分别编号为A、B、C、D,其中,A为最优选配比,B为组方最小范围配比,C为组方最大范围配比,D为组方范围内任意配比。各配比的中药材数量如表1所示。
表1 各配比中药材数量表(单位:kg)
制备方法采用以下步骤:
(1)取处方量的丰花草、番红花、红天葵、掌叶榕、营实、淮通、一枝蒿、爬山虎、泽兰、小粘药、徐长卿、金银花、茜草、紫河车、何首乌,加入所述药材总重量的7 倍量水煎煮二次,第一次煎煮2 小时,第二次煎煮1小时,合并煎液,滤过,滤液减压浓缩,加入乙醇使得溶液的含乙醇量为65%,溶液放置24小时,滤过,滤液回收乙醇,浓缩得稠膏;
(2)将上述所得稠膏干燥后粉碎成细粉,过筛,按照传统工艺制备成口服液,生药含量约为0.28g生药/ml。
实施例2、本发明药物的动物毒性试验
(一)、急性毒性试验
1、试验药品:本发明实施例1所制得中药口服液编号为A-D。试验所用动物:普通级NIH小鼠,体重21g±6g,雌雄各半,雌性小鼠均无孕;
2、应用小鼠进行急性毒性实验表明:小鼠灌胃实施例1的中药口服液,在784.9g生药/kg剂量下,给药后小鼠出现轻微活动减少,1小时左右恢复正常,给药后连续观察7天,无一小鼠死亡,且全身状况、饮食、摄水、小便和体重增长均正常。实验结果表明:小鼠灌胃实施例1的中药口服液的最大给药量为784.9g生药/kg/d(LD50>784.9g生药/kg)。本发明的中药制剂每日临床用药总量为0.18g生药/kg/d;按体重计,小鼠灌胃本发明中药制剂的耐受量为临床病人的4360.6倍。提示该药急性毒性极低,临床用药安全。
(二)、动物长期毒性试验
1、药物:本发明实施例1所得中药口服液。
2、动物:普通级SD大鼠,初始体重217±6g,雌雄各半,雌性大鼠均无孕。
3、方法与结果:
(1)4种中药口服液:均分为高、中、低三个剂量组,单位体重给药量分别为患者服用量的180、60、20倍;
(2)将实验鼠随机分成13组,其中12组分别灌胃4种三个剂量的口服液,剩余一组灌胃生理盐水(患者服用量的40倍);所有13组均连续灌胃180天,观察动物全身毒性反应及严重程度,处死后按操作规程检查各部位,并进行血液学,ALT、BUN及心、肝、脾、肺、肾、胃等主要脏器的病理学检查;
(3)经过长期喂食,13组大鼠均未出现毒性反应。发育良好。肉眼外观及主要脏器未见异常。外周血象及血清ALT、BUN与对照组比较无病理性改变。病理报告心、肝、脾、肺、肾、胃等均未有意义的改变,因此,认为经病理证实,4种中药口服液对动物无慢性毒性表现。
通过以上两个毒性实验,证明本发明按实施例1制作的中药口服液是安全的,无毒副作用的,可以被患者服用。
实施例3、临床药效试验
1、病例选择:选择医院确诊的眼睑湿疹患者88例,其中男53例,女35例,年龄19-47岁,随机分成4组,每组22人,编号A、B、C、D。
2、治疗方法:四组患者依次对应服用本发明实施例1制备的A-D口服液,每次3.6g生药量,每天3次,10天一疗程,治疗一个疗程。
3、疗效判定
