用青蒿素及其衍生物治疗和预防良性色素斑(痣)
本发明涉及局部给药特别是用局部用配方治疗皮肤和黏膜上良性色素斑(痣);特别是痣细胞色素痣、着色斑病和黏膜色素斑的治疗。此外,本发明还涉及适宜于此种治疗的局部用配方。
术语痣细胞痣指的是各种微观组织上由所谓痣细胞构成的良性皮肤病变,色素痣(胎痣、肝色痣)。痣细胞是正常色素带有缺陷形成的细胞,即黑素细胞。几乎每个人身上都会出现不同数目、不同大小和不同颜色强度的黑素细胞痣。痣的外表现型可以是很不相同的。它可为与皮肤齐平面的或者高于皮肤平面的色素痣(球形、有蒂或者平放在皮肤上的)点状也如大平面的、疣状的、隆起的或者光滑的,而着色则从肤色经褐色至黑色。后天性黑素细胞痣的数目随生命过程而增加。具有奇特结构的痣细胞色素痣,有高恶变的危险,并被称为发育异常的或者非典型的痣细胞色素痣。
由痣细胞色素痣也许会发展成恶性黑素瘤,也即黑皮肤癌。在60%以上的情况下,它由痣细胞色素痣形成。在近几十年中,人们注意到,黑素瘤发病率明显上升。1960年在美国寿命风险约1∶600,而当今人们观察到寿命风险为1∶100。因此,举例来说,根据Prof.Dr.Matthias Volkenandt(Klinikfür Dermatologie und Allergologie der Ludwig-Maximilians-
Figure A20068003656900061
München,Frauenlobstrasse 9,80337München)所说,黑素瘤在巴伐利亚州地区的发病率为每100000个居民每年约14(也即14个新病例)。这相当于寿命风险约1%(每100个居民在一生中有一个患黑素瘤)。就这个数字来说,黑素瘤并不是人类最频繁发生的肿瘤,不过,按照Volkenandt所述,发病率上升之高,没有别的肿瘤与之相提并论。
按照现今的知识状况,还没有克服痣细胞色素痣变质的预防性诊治和疗法。具有高危险的痣的变质首先要手术切除。早些时候,激光处理在美容方面,发挥作用。所有两种方法都是侵入性的、带有一定风险(瘢痕形成、皮肤变色等)并且与高费用相联系。
后天性痣的出现,总是一种小的、有时候小得用显微镜才能看见的红小点(出血或血管瘤)。从这种痣最初阶段开始,往往发展成较大的红色、有点隆起的斑点。然后,从这些痣最初阶段起始,形成大小、棕褐色度和结构不同的褐色痣细胞色素痣。
青蒿素(也称Qinghaosu)是一种具有过氧化物基团的倍半萜烯内酯,迄今为止它主要作为对全身起作用的抗疟疾剂来研究和使用。青蒿素很难溶于水;但是青蒿素的水溶性衍生物已被研制出来。在EP-A-0 428 773中,记叙了全身性或局部应用青蒿素及其衍生物来治疗牛皮癣、病毒性疾病(疣、触染性软疣和羊痘)、紫外线诱发的疾病(多形的光致皮肤病、“胶原质脉管疾病”、恶化前的角化病(

优选的是上述式(I)所示的那些活性物质,它们选自青蒿素、二氢青蒿素、含羧基的衍生物(特别是青蒿酯)、蒿甲醚(Artemeter)、蒿乙醚、二氢青蒿素的碳酸丙酯和蒿酸
Figure A20068003656900141
特别优选的是青蒿素、二氢青蒿素和青蒿酯。
式(I)所示的化合物可以单独使用,或者以两种或多种这些化合物的组合形式来使用。
式(I)的化合物,特别是青蒿酯,对预防后天性痣细胞色素痣也有效。为预防痣细胞色素痣起见,将式(I)的化合物,特别是青蒿酯,大面积涂到整个皮肤上,涂到具有形成痣的高可能性的皮肤痛觉过敏带上,或者涂到已看得见的早期痣上。具有形成痣的高可能性的皮肤痛觉过敏带,一方面是频繁暴露于紫外线照射的皮肤局部。另一方面,这种皮肤痛觉过敏带,常存在于已形成痣细胞色素痣的周围(例如典型地以多达5cm的半径围绕已存在的痣)。此外,式(I)所示的化合物,特别是青蒿酯,还具有其他有利的特性,即它们显然已存在早期痣,但还如此微小使得凭裸眼几乎辨别不出。在式(I)所示化合物的作用下,这种仍辨认不清的早期痣首先形成小红点,数日之后变成深色至黑色,而且部分像深色、具有位于微孔中的结晶体。在一些有利的情况下,顶射显微镜检查法预先检查成问题的皮肤部位就成为不必要。
为应用起见,可将式(I)的活性物质配制成适于局部使用,特别是适于局部表面(皮肤)应用的配方制剂。所制配方制剂(配制品)中的活性物质浓度并不特别关键。以配方制剂的总重量计可以制备浓度约0.1%(重量)至约40%(重量)的配方制剂。为了治疗痣细胞色素痣(先天性=胎痣,或者后天性),以配方制剂的总重量计,配方制剂优选含有约5%(重量)至约20%(重量)的活性物质,特别优选含有约10%(重量)。为预防后天性痣细胞色素痣起见,以配方制剂的总重量计配方制剂优选含有至多约5%(重量)的式(I)所示化合物;更确切地说,优选含有约1%(重量)至约5%(重量)。生物活性物质的确切治疗所需量,取决于有效物质本身、所用的基料(Grundlage)、所制盖伦剂型(例如软膏、悬浮液、药膏、硬膏、乳膏剂、凝胶、溶液)以及所用的添加剂,而且可以由技术人员通过简单的效果试验来确定。
存在的痣细胞色素痣(先天性=胎痣,或者后天性)的治疗时间取决于痣的种类、大小、结构、色素沉着以及年代。优选以高浓度的式(I)所示化合物进行周期性的治疗。第一疗程(Behandlungstagen)后,第一反应通常是明显的。直到明显好转或者变化,即表现出痣细胞色素痣逐渐退色或者消失,可以持续二至数月。就陈旧性患者而言,此时间段会更长一些,因为表皮更新随陈旧性增加而持续得更长一些。
就预防后天性痣细胞色素痣而言,应用2~3次即足矣。较大的早期痣最好治疗更长一些时间,直到早期痣逐渐退色或消失为止。
式(I)所示的活性物质应该视治疗措施(Therapieansatz)而定,不同程度地深深侵入皮肤:
-就治疗痣细胞色素痣(先天性=胎痣,或者后天性)而言,应视痣的类型及陈旧程度而定,活性物质优选进入上真皮。
-就预防后天性痣细胞色素痣而言,活性物质最好通过真皮直抵表皮及真皮间边界的交界区域。
对惰性的通常用于局部配方制剂的底料来说,作为式(I)活性物质的配方制剂底料适于所有这些活性物质。特别是用于局部配方制剂的这种底料:凡士林、脂肪、蜡、脂肪酸酯、石蜡、油、硅酮及其聚合物。优选是将活性物质和约60%(重量)至约99.9%(重量),更优选与约%(重量)80至约95%(重量)以制成的配方制剂计的配方制剂底料一起进行配制。如果使用亲水/含水局部配方制剂底料如水凝胶、乳膏剂,则活性物质可借助纳米胶囊封装,包封在脂质体内(Einschluss in Liposomen)或者例如与环糊精形成络合物,来防止其分解。关于青蒿素及其衍生物与环糊精的络合,举例来说,请参见US-A-2005/187189。
按照德国药典,具有非水单相底料如无水纯脂肪相的局部配方制剂被称作软膏。其中使用了本发明式(I)活性物质的软膏,由这样一种软膏底料组成,该软膏底料可含有一种或多种细微分散的活性物质,以在皮肤上应用。
当该局部配方制剂应为软膏时,该配方制剂底料可优选由室温下具有正辛醇/水的分配系数约1至约105,更优选约10至约105,特别优选约50至约104的亲油组分组成。在此场合下,该配方制剂底料的例子是凡士林、脂肪、蜡、脂肪酸酯、石蜡、油、硅酮及其聚合物(例如聚二烷基硅氧烷、硅酮弹性体、硅酮-蜡、硅酮乳化剂)。
涂敷软膏时,式(I)活性物质从包围它的局部制剂底料中出来,并进入皮肤中。该亲脂性底料与皮肤粘附得非常牢固,并向外形成拒水层。此层同样还阻止了水分从皮肤向外逸出(阻碍作用)。由于这种作用,皮肤被保持湿润,并变得暖和,因为可以蒸发的水不多。由于湿度提高,皮肤也更具弹性,这促进了活性物质的吸收。
跟软膏相反,二相体系(水相和脂肪相)被命名为乳膏。式(I)所示的化合物也可配制成乳膏。就脂肪相而言,可以采用诸如上面对软膏底料举例说明的同一类物质。水相中除水之外也可有选择地含有各种能使皮肤耐受的水相pH的缓冲剂物质,或者也可含有已知的成凝胶聚合物如羟基丙基甲基纤维素、羧甲基纤维素、含有交联剂(例如硼砂或者诸如Mg2+或者Ca2+的多价金属阳离子)的聚乙烯醇以及以及类似物质。为了进行乳化,可以使用常用的皮肤耐受性表面活性物质,例如脂肪酸一甘油酯和脂肪酸二甘油酯、聚氧乙烯(40)氢化的蓖麻油(Cremophor
Figure A20068003656900171
)或者卵磷脂。
作为局部配方制剂的辅料,可以是常用的渗透促进剂(诸如二甲基乙酰胺、二甲基甲酰胺、丙二醇、脂肪醇、三乙醇胺、二甲亚砜、氮酮以及其他)、改进效果的角质层分离药(例如水杨酸、尿素、类维生素A)和防腐剂。添加剂一般用于改进盖伦剂型的效果、稳定性、持久性和坚度。
优选将式(I)所示的化合物配制成基本上不含增强渗透的材料的局部配方制剂。还优选配制式(I)所示的化合物,使之基本上不含(C5-C19)一元羧酸、其酯及其酰胺。在本专利申请范围内,“基本上不含”应理解为,局部配方制剂以配方制剂的总量计含有小于1%(重量),优选小于0.1%(重量)的增渗材料。
用于糊剂、软膏、乳膏剂、溶液、凝胶、喷雾剂或者悬浮液的式(I)化合物,优选是所有含有一个羧基的衍生物,特别是青蒿酯。在此情况下,羧基可以有选择地以碱金属盐、碱土金属盐或铵盐的形式存在。
为在皮肤上应用或者应用到皮肤中,将式(I)活性物质以局部配方制剂形式、特别是以糊剂、软膏、悬浮液、溶液、凝胶、喷雾剂或者乳膏的形式、特别优选以软膏的形式、涂到硬膏(Pflaster)上。硬膏可以有选择地是一种吸收或吸入局部配方制剂的材料。活性物质当然也可直接悬浮于或者溶于硬膏的惰性粘合剂中;在类似于先前已知的硬膏中,例如用于东莨菪碱(例如“Scopoderm TTS”)或者用于雌二醇(例如“Estraderm TTS”)中的硬膏。以此方式,活性物质可直接并且在长时间内与待处理部位接触。另外还产生闭塞作用,该作用改进了活性物质的渗透。
式(I)活性物质的其他给药方式是糊剂、溶液、悬浮液、凝胶与乳膏剂以及喷雾剂。所列举活性物质的半固态或者液态配方,也可以栓(Stift)的形式(例如类似毡棒那样
Figure A20068003656900172
以精确剂量)或者以卷(Roller)(在相宜的底料(Grundlage)、溶液、悬浮液、软膏、乳膏剂中含有活性物质)的形式存在。
其他局部的、可按本发明使用式(I)化合物的用药形式实例是涂药器,该涂药器借助超声波、借助电场或者借助微型针来促进式(I)化合物渗入皮肤或黏膜。使用超声波并按本发明可使用的先前已知的涂药器,例如在US-B6,908,448中已予公开,特此一并资作参考。使用电场投药活性物质(因此,其采用离子电渗疗法原理)的涂药器,久已为人所知。按本发明,它们适用于那些属盐类的式(I)活性物质,即如式中X为CHOZ或者CHNRZ,其中Z选自间-CH2(C6H4)COOM和对-CH2(C6H4)COOM、SO2OM和POR4R5,式中R4和R5中之一为OM,并为其他直链或支链的(C1-C6)烷氧基或OH,而M则为药学上可接受的阳离子。就用于将本发明活性物质局部投药到皮肤上的、带微型针的先前已知涂药器而言,请参阅US-A-2005/065463,该文件同样特此一并资作参考。
按本发明可以使用的局部投药方式的另一个实例是一项技术,其中借助吸盘将待处理部位的皮肤吸起,并在皮肤的提高部位上,将真皮的部分层厚用机械方式切除,例如用刀刃。部分切除真皮的皮肤部位,对式(I)所示化合物来说是渗透性的,并允许在这些部位上,进行深入真皮下层的局部治疗。为此必需的器械已描述于作为参考而包括在本申请内的WO-A-95/15783中。
用蒿素及其衍生物(二氢青蒿素,蒿乙醚,蒿甲醚,青蒿酯及其半合成衍生物和合成的类似化合物)进行一种少风险、非侵入的预防性或治疗性处理后天性痣细胞色素痣或者后天性或先天性痣细胞色素痣(=胎痣),是处理痣细胞色素痣中的一个巨大进步,并能有力减少皮癌危险。因此,本发明不仅在医学上而且在社会经济学上都具有巨大意义。在所记载的、用式(I)所示化合物,特别是青蒿酯进行的局部治疗中,未观察到该化合物对皮肤的变应性反应。值得注意的还有,健康组织不受损害,而且治疗是无痛、简易的。
鉴于迄今为止获得结果,可看出:用青蒿素及其衍生物进行的局部治疗(lokale Therapie),特别是局部定位治疗(topische Therapie)非常有效,而且作为痣的预防和治疗,在更长时间内可注意到,比传统的介入性医治方法费用不大,而且风险更小。

实施例9a~9i:治疗或预防色素痣中的局部(皮肤)应用
a)一名13岁男孩,有深褐色隆起胎痣(发育异常的胸痣细胞痣),结构不平整,直径约1.2厘米,用实施例2a的10%青蒿酯凡士林软膏每周治疗2~3次。2周后,胎痣为淡褐色,带有一对深色、小点状部位,看起来像“结晶出来的”染料。所述胎痣是干燥的并有鳞屑,看起来象从“内部”开始萎缩。
b)一名妇女,在皮肤表面有3个黑色隆起的胎痣(躯干交界痣),直径为0.5至1.0cm,应用实施例2a的10%青蒿酯凡士林软膏,在闭塞的条件下(以硬膏形式),每周3次过夜。一周后,在每一胎痣上,可辨认出深色部位。3周后,皮肤连同深色晶体样形成物一起脱落。留下三处浅色母斑,带有无色素部位,该部位不再突起于皮肤平面。继续治疗导致所处理部位皮肤上的母斑逐渐退色并成鳞片状脱落。
c)治疗2颗早期痣细胞痣,也即称为皮下淤血,皮肤部位隆起直径0.3~0.4cm:三次应用实施例2a的含10%青蒿酯软膏的硬膏过夜,两周后颜色发生变化,浅红色形成物带有深色小点。可将隆起的有变化皮肤部位揭下。留下两个小伤口,由于提前揭下,伤口痊愈了。
d)一名女受检者,有一颗痣直径约3~4cm(基底细胞癌),用实施例1的10%青蒿酯软膏超过3月(周期性的,晚上,每隔2周)。该痣表示初期的(类似炎症过程的)发红。3个月后,可以看得出来萎缩(关于颜色和结构)约90%。约5个月后,该痣不再可见。
e)一名女性受检者,臂上有一颗痣(交界痣),同样用实施例1的10%青蒿酯软膏。因为该女性受检者未注意观察,故而不能在此精确说明给药频繁程度;但给软膏持续数周以上。而今该痣勉强还能看得出来。
f)一名13岁男性受检者,在鼻根-眼区有一颗先天性痣,在闭塞(硬膏)的条件下,两个月内每周用实施例1的10%青蒿酯软膏2至3次。该痣有初期的许多深色小点。它反应得很慢。然而,最初的成功已经呈现。它总起来变浅许多,而且具有多个肤色的区域。
g)一名13岁女患者,有一颗真皮痣,3日内用实施例1的10%青蒿酯软膏。发生立即集中在痣中形成的3个深色部位,而且剩余范围几乎无色。
h)一名女性受检者,在已有大量痣细胞色素痣(交界痣)的腹部,大面积使用实施例1的10%青蒿酯软膏两次(每隔2天1次)。早在第2个治疗日,除了已经存在的痣之外,红色的、初期所述种类的部分早期痣,以细微小点形式可见,它们不均匀地分布在整个已处理的表面上。该早期痣本身是已有,但仅仅由于用软膏治疗而首次可见。2~3日后它们变为深色至黑色。在有些部分上,它们看来象深色、位于微孔中的晶体。在2~3周内,当用指甲在其上稍稍搔刮时,它们随同表皮角质层脱落或剥离。
i)一名女性受检者,用实施例1的软膏处理了其手背,手背上有一些大小不等的色素痣(肝色痣)。这些已有的痣和早期痣明显退色,并随着处理时间延长(7或者10天)逐渐消失。停止治疗后,色素痣颜色变浅。4周后,它们勉强还可见至不再可见。
实施例10:局部应用于甲真菌感染治疗
甲真菌侵袭中足趾和大足趾:半数大足趾的指甲遭侵害。用常规药物如Lamisil进行治疗,成效甚微。实施例2a的10%青蒿酯凡士林软膏每周用3~4次。该软膏主要应用于甲床和指甲下。2周后,早已可观察到明显好转。4周后,中足趾上的变色完全消失,或者不再变深。坏死的大足趾甲部剥落。其余指甲的治疗,更容易且更有效。活性物质无阻碍地达到健康甲部的交界部位。重新长出来的指甲是正常的,没有浅的色变。在真菌感染时,特别在指甲感染真菌时,可预期,没有必要用抗真菌药进行另外的全身性治疗,从而不仅该费用低,而且抗真菌治疗的副作用危险也低微。

The term nevus cell nevus refers on the various microstructures the optimum dermatosis by so-called nevus cellularity, nevus cell nevus (birthmark, Hepatic nevus).The nevus cell is that normal pegmentation has the cell that defective forms, i.e. melanocyte.Almost everyone can occur the melanocytic nevus of different numbers, different size and different colours intensity on one's body.The outer Phenotype of nevus can be very inequality.It can be with the nevus cell nevus skin flush or that be higher than skin plane (spherical, the base of a fruit is arranged or lie on the skin) point-like also as planar greatly, verrucose, protuberance or slick, painted then from the colour of skin through brown to black.The number of posteriority melanocytic nevus increases with life process.Nevus cytochrome nevus with fanciful structures, the danger that has height to cancerate, and be called as dysplastic or atypical nevus cytochrome nevus.
Perhaps can develop into malignant melanoma by nevus cytochrome nevus, also be the casting skin cancer.Under the situation more than 60%, it is formed by nevus cytochrome nevus.In nearly decades, it should be noted that the melanoma sickness rate obviously rises.Nineteen sixty is about 1: 600 of U.S.'s life-span risk, and current people to observe the life-span risk be 1: 100.Therefore, for instance, according to Prof.Dr.Matthias Volkenandt (Klinikf ü r Dermatologie und Allergologie der Ludwig-Maximilians-
Figure A20068003656900061
M ü nchen, Frauenlobstrasse 9,80337M ü nchen) said, melanoma is annual about 14 (they also being 14 new cases) of per 100000 residents at the geographic sickness rate in state, Bavaria.This is equivalent to about 1% (per 100 residents are having a trouble melanoma in life) of life-span risk.With regard to this numeral, melanoma is not the tumor of human the most frequent generation, and but described according to Volkenandt, the height of sickness rate rising does not have other tumor to mention in the same breath with it.
According to knowledge situation now, also do not overcome nevus cytochrome nevus rotten preventative diagnosis and treatment and therapy.The rotten excision of at first wanting with nevus of high-risk.In early time, laser treatment plays a role aspect beauty treatment.All two kinds of methods all be invasive, have certain risk (cicatrization, dyschromasia etc.) and interrelate with high cost.
The appearance of posteriority nevus, always a kind of red point (hemorrhage or hemangioma) little, that sometimes little handy microscope just can be seen.From this nevus initial period, the speckle that often develop into bigger redness, a bit swells.Then, initial from these nevus initial periods, form the brown nevus cytochrome nevus big or small, that brown colourity is different with structure.

Particularly preferably be arteannuin, dihydroartemisinine and artesunate.
Chemical compound shown in the formula (I) can use separately, perhaps uses with two or more these combination of compounds forms.
The chemical compound, particularly artesunate of formula (I), also effective to prevention posteriority nevus cytochrome nevus.For the purpose of prevention nevus cytochrome nevus, with the chemical compound of formula (I), particularly artesunate, large tracts of land is coated onto on the whole skin, is coated onto on the head zone with the high likelihood that forms nevus, perhaps is coated onto on the observable early stage nevus.Head zone with the high likelihood that forms nevus is the local skin that frequently is exposed to ultraviolet radiation on the one hand.On the other hand, this head zone, often be present in formed nevus cytochrome nevus around (for example typically with the radius of 5cm nearly around already present nevus).In addition, the chemical compound, particularly artesunate shown in the formula (I) also has other favourable characteristics, and promptly obviously there has been early stage nevus in they, but also so small making almost can not distinguished with bore hole.Under the effect of chemical compound shown in the formula (I), thisly recognize that still unclear early stage nevus at first forms small red dot, become after a few days dark to black, and the part picture dark, have a crystalline solid that is arranged in micropore.Under some favourable situations, microscopy is penetrated on the top, and to check that in advance debatable skin part just becomes unnecessary.
For the purpose of using, the active substance of formula (I) can be mixed with and be suitable for local the use, particularly be suitable for the pharmaceutical formulation that local surfaces (skin) is used.Active material concentration in the made pharmaceutical formulation (preparation) is not crucial especially.Gross weight in pharmaceutical formulation can prepare the pharmaceutical formulation of about 0.1% (weight) of concentration to about 40% (weight).In order to treat nevus cytochrome nevus (congenital=birthmark, perhaps posteriority), in the gross weight of pharmaceutical formulation, pharmaceutical formulation preferably contains 5% (weight) of having an appointment to the active substance of about 20% (weight), especially preferably contains 10% (weight) of having an appointment.For the purpose of prevention posteriority nevus cytochrome nevus, preferably contain chemical compound shown in the formula (I) of about at the most 5% (weight) in the gross weight pharmaceutical formulation of pharmaceutical formulation; Or rather, preferably contain 1% (weight) of having an appointment to about 5% (weight).The definite treatment aequum of bioactive substance, depend on active substance itself, used base material (Grundlage), made lid human relations dosage form (for example ointment, suspension, ointment, plaster, ointment, gel, solution) and used additive, and can determine by simple effect test by the technical staff.
The treatment time of the nevus cytochrome nevus that exists (congenital=birthmark, perhaps posteriority) is depended on kind, size, structure, pigmentation and the age of nevus.Preferably periodically treat with chemical compound shown in the formula (I) of high concentration.After first course of treatment (Behandlungstagen), first reaction is normally tangible.Up to being clearly better or changing, promptly show nevus cytochrome nevus and fade gradually or disappear, can continue two to the several months.With regard to the old patient, this time period can be more longer, continues more longerly because epidermal renewal increases with old.
With regard to prevention posteriority nevus cytochrome nevus, promptly it is enough to use 2~3 times.Bigger early stage nevus is preferably treated the more longer time, till early stage nevus is faded gradually or disappears.
Active substance shown in the formula (I) should be decided on treatment measure (Therapieansatz), invades skin to some extent deeply:
-just treating nevus cytochrome nevus (congenital=birthmark, perhaps posteriority), should decide on type and the outmoded degree of nevus, active substance preferably enters corium.
-with regard to prevention posteriority nevus cytochrome nevus, active substance preferably directes reach the juncture area on border between epidermis and corium by corium.
Concerning the inert bed material that is generally used for the local prescription preparation, be suitable for all these active substances as the pharmaceutical formulation bed material of formula (I) active substance.This bed material especially for the local prescription preparation: vaseline, fat, wax, fatty acid ester, paraffin, oil, silicone and polymer thereof.Preferably with active substance and about 60% (weight) to about 99.9% (weight), more preferably prepare in the pharmaceutical formulation bed material of the pharmaceutical formulation made with about % (weight) 80 to about 95% (weight).If use hydrophilic/aqueous topical pharmaceutical formulation bed material such as hydrogel, ointment, then active substance can encapsulate by Nano capsule, be encapsulated in liposome interior (Einschluss in Liposomen) or for example form complex, prevent its decomposition with cyclodextrin.Complexation about arteannuin and derivant and cyclodextrin for instance, sees also US-A-2005/187189.
According to Deutscher Arzneibucs, the local prescription preparation with the single-phase bed material of non-water such as anhydrous pure fat phase is known as ointment.Wherein used the ointment of formula of the present invention (I) active substance, be made up of a kind of like this ointment bed material, this ointment bed material can contain the active substance of one or more fine dispersion, to use on skin.
When this local prescription preparation should be ointment, this pharmaceutical formulation bed material can be preferably by the partition coefficient that has n-octyl alcohol/water under the room temperature about 1 to about 10 5, more preferably from about 10 to about 10 5, preferred especially about 50 to about 10 4Lipophilic ingredient form.Under this occasion, the example of this pharmaceutical formulation bed material is vaseline, fat, wax, fatty acid ester, paraffin, oil, silicone and polymer thereof (for example polydialkysiloxane, silicone elastomer, silicone-wax, silicone emulsifier).
During coating ointment, formula (I) active substance comes out from the topical formulations bed material that surrounds it, and enters in the skin.This lipotropy bed material and skin adherence get very firm, and outwards form water repellent layer.This layer has equally also stoped moisture from skin outwards overflow (inhibition).Because this effect, it is moistening that skin is held, and become warm, because the water that can evaporate is few.Because humidity improves, skin also has more elasticity, and this has promoted absorption of active agents.
Opposite with ointment, two phase systems (water is with mutually fatty) are named as emulsifiable paste.Chemical compound shown in the formula (I) also can be mixed with emulsifiable paste.With regard to the fat phase, can adopt such as top the illustrational same class material of ointment bed material.Also can contain the various buffer material that can make the water pH of skin tolerance outside aqueous phase dewaters selectively, perhaps also can contain known one-tenth gelatin polymer such as HYDROXY PROPYL METHYLCELLULOSE, carboxymethyl cellulose, contain cross-linking agent (Borax or for example such as Mg 2+Perhaps Ca 2+Multivalent metal cation) polyvinyl alcohol and and similar substance.In order to carry out emulsifying, can use skin-tolerant surfactant commonly used, for example fatty acid monoglyceryl ester and fatty acid two glyceride, the hydrogenant Oleum Ricini (Cremophor of polyoxyethylene (40)
