OBJECTIVE To investigate the penetration effect of solid microneedle in vivo and in vitro, the model drug ketoprofen was administered in the form of a patch. METHODS Using a rat skin penetration test, the effects of microneedle length, pre-treatment pressure, pre-treatment time, and types of needle on the penetration enhancement of ketoprofen in vitro were investigated. The pharmacokinetic characteristics of ketoprofen patches applied to the back of rats after different microneedle treatments were investigated, as well as the effect of the ketoprofen patch on promoting permeability in vivo. RESULTS In vitro, skin permeation tests revealed that after microneedle pretreatment, the permeation rate and permeation volume of the patch were significantly increased (P<0.05) and the permeation time lag was significantly shortened (P<0.05) after microneedle pretreatment, while the permeation promotion effect was related to the pressure, time, microneedle length and type of microneedle pretreatment. After microneedle pretreatment of the skin (pressure: 1-7 N, time: 1-5 min, microneedle length: 200 μm-300 μm), the cumulative permeation amount of the experimental drug for 24 hours increased by 1.16-3.09 times, and the permeation delay decreases by 0.20-2.50 h. As the results of in vivo pharmacokinetic in rats, ρmax (10.86±0.80) μg·mL-1 and AUC0→t (108.10±17.06) μg·h·mL-1 after 300 μm roller microneedle pretreatment of the skin, which were significantly greater than the control ρmax (0.42±0.03) μg·mL-1 and AUC0→t (7.46±0.98) μg·h·mL-1(P<0.05). ρmax and AUC0→t were increased by 25.9 times and 15 times. CONCLUSION Solid microneedle pretreatment of skin significantly improves in vitro penetration and in vivo skin absorption of ketoprofen patches through rat skin, with a more significant promotion effect in vivo penetration.

目的 以药物酮洛芬为模型药物,研究并评价实心微针辅助透皮贴剂给药在体内、外的药物促透效果。方法 采用大鼠皮肤渗透实验,考察微针的长度、预处理压力、预处理时间以及针型对酮洛芬的体外促透效果的影响;并研究了大鼠在体皮肤经不同微针预处理后,酮洛芬贴片于大鼠背部皮肤给药的药物动力学特征,评价其体内促透效果。结果 离体皮肤渗透试验结果显示,经微针预处理后贴片的药物经皮渗透速率和渗透量显著提高(P<0.05),渗透时滞显著缩短(P<0.05),促透效果与微针预处理的压力、时间、微针长度与类型相关,在压力为1~7 N、时间1~5 min、针长200~300 μm条件下,多次实验药物24 h的累积渗透量增加1.16~3.09倍,渗透时滞缩短0.20~2.50 h。根据大鼠体内药动学结果,当300 μm滚轮微针预处理皮肤后ρmax(10.86±0.80)μg·mL-1和AUC0→t(108.10±17.06) μg·h·mL-1均显著大于对照组ρmax(0.42±0.03 )μg·mL-1和AUC0→t(7.46±0.98 )μg·h·mL-1(P<0.05),达峰时间(tmax)亦显著快于对照组(P<0.05)。ρmax和AUC0→t分别提高25.9倍和14.5倍。结论 实心微针预处理皮肤可显著提高酮洛芬贴片经大鼠皮肤的体外渗透和在体皮肤吸收,在体促透效果更显著。

目的 以药物酮洛芬为模型药物,研究并评价实心微针辅助透皮贴剂给药在体内、外的药物促透效果。方法 采用大鼠皮肤渗透实验,考察微针的长度、预处理压力、预处理时间以及针型对酮洛芬的体外促透效果的影响;并研究了大鼠在体皮肤经不同微针预处理后,酮洛芬贴片于大鼠背部皮肤给药的药物动力学特征,评价其体内促透效果。结果 离体皮肤渗透试验结果显示,经微针预处理后贴片的药物经皮渗透速率和渗透量显著提高(P<0.05),渗透时滞显著缩短(P<0.05),促透效果与微针预处理的压力、时间、微针长度与类型相关,在压力为1~7 N、时间1~5 min、针长200~300 μm条件下,多次实验药物24 h的累积渗透量增加1.16~3.09倍,渗透时滞缩短0.20~2.50 h。根据大鼠体内药动学结果,当300 μm滚轮微针预处理皮肤后ρmax(10.86±0.80)μg·mL-1和AUC0→t(108.10±17.06) μg·h·mL-1均显著大于对照组ρmax(0.42±0.03 )μg·mL-1和AUC0→t(7.46±0.98 )μg·h·mL-1(P<0.05),达峰时间(tmax)亦显著快于对照组(P<0.05)。ρmax和AUC0→t分别提高25.9倍和14.5倍。结论 实心微针预处理皮肤可显著提高酮洛芬贴片经大鼠皮肤的体外渗透和在体皮肤吸收,在体促透效果更显著。

OBJECTIVE To investigate the penetration effect of solid microneedle in vivo and in vitro, the model drug ketoprofen was administered in the form of a patch. METHODS Using a rat skin penetration test, the effects of microneedle length, pre-treatment pressure, pre-treatment time, and types of needle on the penetration enhancement of ketoprofen in vitro were investigated. The pharmacokinetic characteristics of ketoprofen patches applied to the back of rats after different microneedle treatments were investigated, as well as the effect of the ketoprofen patch on promoting permeability in vivo. RESULTS In vitro, skin permeation tests revealed that after microneedle pretreatment, the permeation rate and permeation volume of the patch were significantly increased (P<0.05) and the permeation time lag was significantly shortened (P<0.05) after microneedle pretreatment, while the permeation promotion effect was related to the pressure, time, microneedle length and type of microneedle pretreatment. After microneedle pretreatment of the skin (pressure: 1-7 N, time: 1-5 min, microneedle length: 200 μm-300 μm), the cumulative permeation amount of the experimental drug for 24 hours increased by 1.16-3.09 times, and the permeation delay decreases by 0.20-2.50 h. As the results of in vivo pharmacokinetic in rats, ρmax (10.86±0.80) μg·mL-1 and AUC0→t (108.10±17.06) μg·h·mL-1 after 300 μm roller microneedle pretreatment of the skin, which were significantly greater than the control ρmax (0.42±0.03) μg·mL-1 and AUC0→t (7.46±0.98) μg·h·mL-1(P<0.05). ρmax and AUC0→t were increased by 25.9 times and 15 times. CONCLUSION Solid microneedle pretreatment of skin significantly improves in vitro penetration and in vivo skin absorption of ketoprofen patches through rat skin, with a more significant promotion effect in vivo penetration.

经皮给药系统研发的关键在于克服皮肤角质层的屏障作用[1],改善药物的经皮渗透性能。微针阵列技术,通过穿刺角质层产生数百上千个微创通道,从而促进药物的经皮吸收,提高药物的生物利用度,为经皮给药领域注入了新的活力[2]。与其他物理促透方法相比较,微针对皮肤的作用相对可逆,且对皮肤的损伤性较小。此外,微针穿刺皮肤角质层可以使大分子药物和亲水性药物也能通过皮肤迅速进入血液循环[3],从而极大地拓展了经皮给药的药物范围[4-7]
酮洛芬(ketoprofen,KP)贴片主要用于缓解类风湿性关节炎、骨性关节炎、强直性脊柱炎、急性扭伤等不同病因引起的轻中度疼痛。传统的促渗技术虽然可以提高经皮吸收率,但时滞长起效慢,联合微针技术给药,则能缩短时滞、增加经皮渗透量,使得药物起效更快、药物渗透量大、疗效更好[8-9]
本实验使用实心微针作为皮肤的前处理工具,辅助KP贴片使用,评价大鼠皮肤经微针前处理后对药物经皮渗透的体内外促透效果。
Franz透皮扩散池(Logen公司,FDC-6T型),高效液相色谱仪(Agilent公司,1260 LC型),LC-QTOF/MS(Waters公司,Synapt G2-UPLC联用),电子分析天平(Mettler Toledo公司,XS205DU型),电子天平(Sartorius公司,BSA224S型),宠物用电推剪(科德士公司,CP-8000型),电动剃须刀(飞科公司,FS620型),滚轮型微针(Clinical Resolution Laboratory公司),印章型微针(GENOSYS公司),漩涡混合器(IKA公司,Vortex 3型),离心机(Eppendof公司)等。
KP贴片(实验室自制,剂量为0.36 mg·cm-2),KP对照品(批号:03908kov)、吲哚洛芬(批号:127F0834,Sigma公司);乙腈(批号:JA025530,Merck公司);乙酸(批号:12070463,Tedia公司);甲醇(批号:1837107623,Merck公司),纯化水等,雌性豚鼠(200~250 g)背部皮肤。

大鼠麻醉后用颈部脱臼法处死,剃除背部毛发并分离背部皮肤,去除皮下脂肪组织,在生理盐水中洗净后用滤纸吸干备用。实验组采用微针预处理离体大鼠皮肤角质层,微针针体垂直于皮肤表面施加一定压力,持续作用一定时间后移除,微针预处理皮肤的力量大小根据电子天平的读数控制[10-11],实验所用的实心微针(×10)见图1
将处理好的皮肤按角质层朝外方向固定于Franz扩散池口,池口面积为0.65 cm2,敷贴KP贴片后进行体外皮肤渗透实验。每池加入4 mL的体积分数40%聚乙二醇(polyethylene glycol,PEG)400-生理盐水(normal saline,NS)作为皮肤接收液,恒温(32±1)℃,搅拌子转速为500 r·min-1。在第4、6、8、10、12和24 h时取样0.5 mL,并同时补充等量空白接收液[12]
测定皮肤接收液样品中KP的含量,按照公式1计算各时间点单位面积累积渗透量(Qn,μg·cm-2)。
Qn= 4 ρ n + i = 1 n - 1 ( 0.5 ρ i )/0.65
其中,ρn表示第n个取样时间点皮肤接收液的药物浓度;ρi表示第i(in-1)个取样时间点透皮接收液的浓度。以Qn对时间(t,h)作图,将所得曲线的直线部分进行线性回归,所得斜率为渗透速率(J,μg·cm-2·h-1),即单位时间内药物透过单位面积的渗透量,时滞为曲线的直线部分与X轴交点。
将微针预处理的实验组与未经微针预处理的对照组结果对比,进行组间t检验,以P<0.05为存在统计学显著性差异[13]

血浆样品室温下解冻,在振荡器涡旋30 s,取50 μL加入1.5 mL离心管中,加入5 μL的内标工作液(2 μg·mL-1)与100 μL含0.1%甲酸的乙腈,涡旋混合1 min,以12 000 r·min-1离心10 min,取上清液5 μL进样分析。
根据2020年版《中国药典》要求,分别针对专属性、线性、灵敏度、基质效应、准确度、精密度和稳定性等进行了验证。
12只雌性SD大鼠分为4组,第一组不经微针预处理作为对照组,第二组为300 μm滚轮型微针实验组,第三组为200 μm滚轮型微针实验组,第四组为200 μm印章型微针实验组。各组大鼠麻醉后用5 N的压力按压3 min,然后在预处理部位敷贴KP贴片给药,给药剂量为4 mg·kg-1
取血时间为:给药前(0 h),给药后0.25、0.5、1、2、3、4、8、12、24、32、48和60 h,撤药时间为给药后24 h。从大鼠尾静脉取血,每次取全血400 μL,分离出血浆200 μL,-20 ℃冰箱保存,用液相色谱-四极杆飞行时间质谱(LC-QTOF/MS)测定各组大鼠血浆中KP 的浓度[14-15]
按照“2.2”项下方法进行实验,未敷贴KP贴片的为空白皮肤接收液样品组,敷贴KP贴片的为KP皮肤接收液样品组,24 h后取样,经0.22 μm滤膜过滤后进样,结果见图2,皮肤和接收液对KP的检测无干扰,该检测方法专属性良好。
配制99.980 0 μg·mL-1的KP储备液,用体积分数40%聚乙二醇400-生理盐水溶液(PEG-NS)稀释至49.940 0、24.970 0、12.480 0、6.242 0、3.121 0、1.561 0、0.780 3、0.390 2、0.195 1、0.097 5、0.048 8、0.024 4 μg·mL-1的系列标准溶液,进样后以峰面积(A)对其质量浓度(ρ)进行线性回归,回归方程为:A=47 989ρ-450.22(r=0.999 9),表明该方法下皮肤接收液中KP在0.024 4~99.980 0 μg·mL-1内峰面积与质量浓度线性关系良好。
采用信噪比法确定该方法下的定量限与检测限,定量限为0.048 8 μg·mL-1(S/N>10),检测限为0.024 4 μg·mL-1(S/N>3)。
供试品溶液的制备:敷贴KP贴片的皮肤渗透实验中,在每个取样时间各取0.5 mL接收液样品,混合后作为供试品溶液。
进样测得供试品溶液峰面积,并代入线性曲线,得到其质量浓度为4.20 μg·mL-1,在供试品溶液中分别加入适量KP标准溶液,配制成加入量分别为5.04 、4.20 、3.36 μg的高、中、低三个质量浓度的样品,测得加样回收率范围为97.02%~107.77%,相对标准偏差(RSD)范围为1.72%~2.04%,表明该方法准确度良好。
取供试品溶液,测定KP的峰面积,每隔1 h进样6次,测得日内精密度RSD为1.17%;连续进样3 d,每份样品测6次,3 d RSD依次为1.02%、1.27%和2.05%。结果表明,该方法精密度良好。
将供试品溶液于室温下放置,分别于0、4、6、8、10、24、48、72和96 h取样0.5 mL,进样后测定各时间点样品中KP的峰面积,RSD为2.21%,稳定性良好,表明供试液室温放置96 h可以满足该方法的检测要求。
考察微针以不同作用压力处理对KP贴片的体外皮肤渗透的影响。将针长为200 μm印章型微针阵列以1 、3 、5 、7 N的压力预处理备好的大鼠离体皮肤3 min,对照组未经微针预处理。各组皮肤渗透曲线见图3,经1、3、5和7 N压力处理的KP渗透速率分别是对照组的1.75、2.15、2.65和2.65倍,24 h累积渗透量分别是对照组的1.16、1.45、1.68和1.73倍,时滞分别比对照组缩短0.88、0.82、1.14、1.14 h,其中5 N组和7 N组之间无显著性差异(P>0.05)。结果显示,KP的累积渗透量及渗透速率随着微针预处理皮肤压力的增加而增加,作用力达到5 N时促透效果趋于平稳。该结果提示,针长为200 μm的微针预处理对药物经离体大鼠渗透促透作用是显著的,大致需要5 N的力能使微针完全穿透皮肤角质层。
考察微针预处理时长对KP贴片的体外皮肤渗透的影响。将针长为200 μm印章型微针阵列以5 N的压力处理备好的大鼠离体皮肤,分别按压1、3和5 min,对照组未经微针处理。各组皮肤渗透曲线见图4,经微针预处理1、3和5 min的KP渗透速率分别是对照组的1.60、1.86和2.12倍,24 h时累积渗透量分别是对照组的1.40、1.68和1.74倍,时滞分别比对照组缩短0.20、1.36和1.45 h,其中3 min组和5 min组没有显著性差异(P>0.05)。结果表明,药物的累积渗透量及渗透速率随着微针预处理皮肤时间的增加而增加,时滞随着时间的增加而缩短,超过3 min促透效果无明显改善,趋于稳定。微针预处理皮肤的时间对药物的渗透有显著影响,主要与微孔周围皮肤组织的弹性回缩程度有关,皮肤是一个弹性体,微针刺入皮肤后所形成的通路是暂时性的,微针刺入皮肤较长时间再移除,微孔周围皮肤弹性回缩减慢,孔洞维持时间长,药物透过量增大。若微针刺入皮肤作用时间较短就移除,则所形成的通路较快关闭,药物渗透速率减小。
考察不同的微针长度对KP贴片的体外皮肤渗透的影响。分别将200和300 μm长度的滚轮型微针以5 N的压力预处理备好的大鼠离体皮肤3 min,对照组未经微针处理。各组皮肤渗透曲线见图5,经200和300 μm微针预处理的KP渗透速率分别是对照组的3.09和2.91倍,24 h累积渗透量分别是对照组的2.43和2.33倍,时滞分别比对照组缩短2.15和2.50 h。与实验组对比,两种长度的滚轮型微针都能显著地提高KP的体外渗透速率和累积渗透量并缩短时滞(P<0.05),但是实验组间无显著性差异(P>0.05),结果表明,200 μm长度的实心微针足以刺穿离体大鼠皮肤角质层,对KP贴片起促透效果。
考察印章型和滚轮型实心微针对KP贴片体外皮肤渗透的影响。用针长都为200 μm的印章型微针和滚轮型微针分别处理备好的大鼠离体皮肤,预处理时间为3 min,压力为5 N,对照组未经微针处理。各组皮肤渗透曲线见图6,经印章型和滚轮型微针处理的KP渗透速率分别是对照组的1.31和1.51倍,24 h累积渗透量分别是对照组的1.36和1.79倍,时滞分别比对照组缩短1.23和1.56 h。与对照组相比,经微针预处理均能显著提高体外渗透速率及累积渗透量并缩短时滞(P<0.05)。滚轮型微针预处理的渗透速率和累积渗透量显著地大于印章型微针(P<0.05),时滞显著小于印章型微针(P<0.05)。结果表明,滚轮型微针促进KP贴片体外渗透效果显著优于印章型微针,这可能与滚轮型微针作用于皮肤时,滚动相较于印章,微针与皮肤的接触更为充分更好地发挥穿刺有关,因此在相同的作用力和作用时间上,对于离体皮肤的穿透效果更好。
按血浆样品的处理方法,配制空白血浆A(不加KP和IS),加标样血浆B(加KP和IS)及样品血浆C(仅加IS)。按照“2.3”项下方法进样检测,结果见图7,在优化的色谱-质谱条件下未发现干扰峰,表明该方法具有良好的专属性,空白血浆中的内源性杂质不干扰样品测定。
取KP储备液和大鼠空白血浆,分别配制相当于KP质量浓度范围为1~1 000 ng·mL-1(1、2、10、50、200、800、1 000 ng·mL-1)的血浆样品,按照“2.2”项下方法处理后按“2.1”项下方法进样分析。标准曲线考察每一浓度2样本分析,定量下限考察进行5样本分析,共考察三条标准曲线。以血浆中KP(x,ng·mL-1)对KP与IS的峰面积比值(y)进行加权(1/x)最小二乘回归,采用Waters QuanLynx软件计算,得到血浆中KP的标准曲线为:y=0.003 177 2x+0.002 701,r=0.998 5。定量下限为1 ng·mL-1,RSD<20%。结果表明,建立的分析方法用于大鼠血浆中KP的检测,线性良好,范围宽,灵敏度良好。
在50 μL空白血浆中加入一定量KP和IS,按“2.3”项下配制800,200和2 ng·mL-1质量浓度的KP样品,作为质量控制(quality control,QC)样品,每个样品各6份,取上清液进样分析,测得KP与IS响应值的比值记做b;另取空白血浆50 μL,按“2.3”项下血浆处理,取上清液加入与QC样品相同系列浓度的KP和IS,每个浓度样品各6份,测得KP与IS响应值的比值记做a;另以相应浓度的对照品和内标的溶液直接进样得到的峰面积比值记做c,每个浓度样品各6份。提取回收率为b与a的比值,基质效应为a与c的比值。
该方法下的血浆中KP在高、中、低三个浓度的提取回收率在89.3%~101.9%内,RSD<15%,符合要求,该方法提取回收率良好;基质抑制效应在85.3%~109.5%,RSD<15%,符合要求,基质抑制效应对血浆KP的定量分析结果影响不大。
配制800,200和2 ng·mL-1的QC样品,每个浓度样品各5份,取上清液进样分析,重复3 d,随行配制标准曲线,计算样品浓度,结果表明,准确度均在标示值的15%范围内,精密度RSD<15%。
考察血浆样品室温放置于进样盘中24 h的稳定性。配制800,200和2 ng·mL-1的QC样品,每个浓度样品各4份,取上清液室温放置于进样盘中0和24 h后进样分析,血浆中KP的含量RSD<15%,表明该血浆样品在室温放置24 h内稳定。
考察血浆样品经历3个冻-融循环后的稳定性。配制800,200和2 ng·mL-1的QC样品,每个浓度样品各5份,在-20 ℃放置使其经历3个冻-融循环后,取上清液进样分析,血浆中KP的含量RSD<15%,表明该血浆样品反复冻融3次能保持稳定。
取空白比格犬血浆50 μL,准确加入高于最高定量浓度的样品各5份,并用空白血浆稀释样品,使得样品浓度在已经建立的标准曲线的最高定量浓度以下,取稀释后的样品按照“血浆样品预处理”项下处理,取上清液进样分析,测定血浆S-KP的含量,计算稀释样品的准确度和精密度。当样品稀释15倍和4倍时,其准确度和精密度分别为9.4%和2.9%,在设定标准之内(<15%),符合要求。且本稀释倍数覆盖了试验样品的所有稀释倍数,满足试验需求。
测得各组大鼠血药浓度的经时变化曲线见图8。利用药动学软件Kinetica进行数据分析,以非房室模型方法计算ρmaxtmax及AUC等药动学参数,并进行组间t检验,以P<0.05为存在统计学显著性差异。各组药动学参数结果见表1,经微针预处理的大鼠的ρmax和AUC0→t均显著大于对照组(P<0.05),0.2 mm滚轮组和0.3 mm滚轮组的药物达峰时间显著快于对照组(P<0.05)。结果表明,微针前处理大鼠皮肤能显著促进KP贴片的经皮吸收,其中300 μm滚轮型微针促透效果显著优于200 μm滚轮型微针(P<0.05),而离体皮肤渗透试验结果表明,滚轮型微针200 μm和300 μm两种针长之间对酮洛芬贴片体外渗透效果没有明显的差异。这可能是因为在体皮肤生理活性优于离体大鼠皮肤,微针刺入后回缩反应能力比离体皮肤更强,从而针长度对药物皮肤渗透有影响。当针长都为200 μm的条件下,滚轮型微针的促透效果显著优于印章型微针(P<0.05),实验结果与体外实验结果一致。另外,微针预处理皮肤的促透效果,相比体外促透,在体促透效果更显著,这可能与在体皮肤具有活性能快速将透过皮肤的药物及时转运进入血液循环有关。
本研究以实心微针作为皮肤的前处理工具,以贴片方式给药模型药物KP,评价微针前处理对药物经皮渗透的影响。体外以离体皮肤渗透实验进行评价,建立并验证了皮肤接收液中KP的HPLC检测方法,结果表明,皮肤用不同的压力及时间预处理后能显著地提高药物的经皮渗透速率和渗透量,并且能明显缩短时滞。通过离体试验初步筛选出了固体微针前处理的条件,并证明滚轮型微针的促透作用要好于印章型微针。体内药动学试验建立了用于大鼠血浆中KP浓度检测的LC-QTOF/MS方法,准确、灵敏、高效,能满足检测需求。结果表明,微针预处理皮肤能显著地促进药物的在体皮肤吸收,微针预处理组的药物在体皮肤吸收效果要显著好于未用微针预处理的对照组。
由于皮肤角质层的屏障作用,大部分药物经皮渗透困难,渗透量小、时滞长,较难达到治疗效果。传统的促透技术如果联合微针技术给药,例如本研究的微针预处理皮肤联合药物贴片给药,则药物的经皮渗透显著增加,渗透时滞更短,解决传统透皮制剂经皮渗透速率较低、药物起效慢等问题,同时可拓展经皮给药的药物范围。本研究结果显示,微针预处理可以扩展酮洛芬贴片用于例如跌打损伤引起的局部急性疼痛。
