OBJECTIVE To investigate the impact of polyethylene oxide (PEO, POLYOXTM), penetration additives, and butylated hydroxytoluene (BHT) on tablet properties and drug release of mirabegron extended release (ER) tablets and provide some ideas of formulating polyethylene oxide based ER tablets for the formulators. METHODS Single-factor-experiment was applied to investigate the impact of formulation components on drug release of mirabegron ER tablets. Different molecular weight (MW), series of particle size and use level of polyethylene oxide, three types of penetration additives (PEG 8000, PEG 4000 and lactose) and several use levels of butylated hydroxytoluene (BHT) were investigated. RESULTS Mirabegron ER tablets formulated with polyethylene oxide WSR N60K at 28% use level got statistically equivalent drug release with marketed mirabegron ER tablets. Higher MW and higher use level of polyethylene oxide led to slower drug release, while lower MW and lower use level led to faster drug release. Particle size of polyethylene oxide WSR N60K did not significantly affect mirabegron drug release. The tablets using either polyethylene glycol (PEG 8000 or 4000) or lactose as penetration additives could achieve equivalent drug release as marketed mirabegron ER tablets. The blend of polyethylene oxide WSR 301 and N12K at ratio of 35∶65 has the same viscosity with polyethylene oxide WSR N60K and led to statistically similar drug release. CONCLUSION Formulation of polyethylene oxide based mirabegron ER tablets are robust.

目的 考察IFF公司的聚氧乙烯(POLYOXTM,商品名:保益乐)、促渗透剂和抗氧化剂丁基羟基甲苯(BHT)对米拉贝隆缓释片释放度的影响。以期为开发聚氧乙烯缓释片提供一些配方经验。方法 采用单因素实验考察配方中聚氧乙烯的相对分子质量、粒径和用量,不同种类促渗透剂[聚乙二醇(PEG) 8000、PEG 4000和乳糖]和BHT的用量对米拉贝隆缓释片释放度的影响。结果 聚氧乙烯 WSR N60K在用量28%时制得的米拉贝隆缓释片与市售贝坦利®米拉贝隆缓释片(RLD)具有统计学相似的释放度。高相对分子质量和高用量的聚氧乙烯得到较慢的药物释放,而低相对分子质量和低用量的聚氧乙烯导致更快的药物释放。聚氧乙烯 WSR N60K的粒径大小对米拉贝隆缓释片的释放度无显著影响。不论是使用聚乙二醇(PEG 8000或4000)还是乳糖作为促渗透剂,制备的缓释片均具有与RLD片相似的释药效果。聚氧乙烯 WSR 301和N12K以35∶65的比例得到的混合物与聚氧乙烯 WSR N60K具有相同的黏度,制备的缓释片也具有统计学相似的药物释放度。结论 聚氧乙烯是良好的亲水凝胶骨架材料,其制得的米拉贝隆缓释片处方稳健,释药稳定。

目的 考察IFF公司的聚氧乙烯(POLYOXTM,商品名:保益乐)、促渗透剂和抗氧化剂丁基羟基甲苯(BHT)对米拉贝隆缓释片释放度的影响。以期为开发聚氧乙烯缓释片提供一些配方经验。方法 采用单因素实验考察配方中聚氧乙烯的相对分子质量、粒径和用量,不同种类促渗透剂[聚乙二醇(PEG) 8000、PEG 4000和乳糖]和BHT的用量对米拉贝隆缓释片释放度的影响。结果 聚氧乙烯 WSR N60K在用量28%时制得的米拉贝隆缓释片与市售贝坦利®米拉贝隆缓释片(RLD)具有统计学相似的释放度。高相对分子质量和高用量的聚氧乙烯得到较慢的药物释放,而低相对分子质量和低用量的聚氧乙烯导致更快的药物释放。聚氧乙烯 WSR N60K的粒径大小对米拉贝隆缓释片的释放度无显著影响。不论是使用聚乙二醇(PEG 8000或4000)还是乳糖作为促渗透剂,制备的缓释片均具有与RLD片相似的释药效果。聚氧乙烯 WSR 301和N12K以35∶65的比例得到的混合物与聚氧乙烯 WSR N60K具有相同的黏度,制备的缓释片也具有统计学相似的药物释放度。结论 聚氧乙烯是良好的亲水凝胶骨架材料,其制得的米拉贝隆缓释片处方稳健,释药稳定。

OBJECTIVE To investigate the impact of polyethylene oxide (PEO, POLYOXTM), penetration additives, and butylated hydroxytoluene (BHT) on tablet properties and drug release of mirabegron extended release (ER) tablets and provide some ideas of formulating polyethylene oxide based ER tablets for the formulators. METHODS Single-factor-experiment was applied to investigate the impact of formulation components on drug release of mirabegron ER tablets. Different molecular weight (MW), series of particle size and use level of polyethylene oxide, three types of penetration additives (PEG 8000, PEG 4000 and lactose) and several use levels of butylated hydroxytoluene (BHT) were investigated. RESULTS Mirabegron ER tablets formulated with polyethylene oxide WSR N60K at 28% use level got statistically equivalent drug release with marketed mirabegron ER tablets. Higher MW and higher use level of polyethylene oxide led to slower drug release, while lower MW and lower use level led to faster drug release. Particle size of polyethylene oxide WSR N60K did not significantly affect mirabegron drug release. The tablets using either polyethylene glycol (PEG 8000 or 4000) or lactose as penetration additives could achieve equivalent drug release as marketed mirabegron ER tablets. The blend of polyethylene oxide WSR 301 and N12K at ratio of 35∶65 has the same viscosity with polyethylene oxide WSR N60K and led to statistically similar drug release. CONCLUSION Formulation of polyethylene oxide based mirabegron ER tablets are robust.

亲水凝胶骨架缓释片是最常用的缓释制剂,因为它们制备工艺相对简单,成本低,缓释效果较好,可以适用于高相对分子质量的药物化合物[1]。膨胀性的亲水性高分子聚合物如聚氧乙烯、羟丙基甲基纤维素(HPMC)、卡拉胶、海藻酸钠、羟丙基纤维素(HPC)和黄原胶等均可以用于制备亲水凝胶骨架缓释片。聚氧乙烯是一种非离子型的线性非交联亲水聚合物,它的化学结构与聚乙二醇(PEG)相同,但相对分子质量高得多,为100 000~7 000 000。由于聚氧乙烯的高水溶性,高溶胀能力,对pH不敏感,生物相容性好,且与大部分原料药和辅料兼容,在制药领域得到广泛应用,比如在渗透泵片中常用作助推层聚合物和含药层助悬剂,用作亲水凝胶骨架材料,生物黏附材料等。聚氧乙烯安全无毒,不会通过胃肠道吸收[2]。口服缓释片中聚氧乙烯的最大日暴露量(MDE)为1 287 mg[3]
本研究以米拉贝隆为模型药,考察了聚氧乙烯的相对分子质量、粒径和用量,促渗透剂的种类(PEG8000、PEG4000和乳糖)和抗氧剂BHT的用量对米拉贝隆缓释片体外释放度的影响,为今后开发基于聚氧乙烯(POLYOXTM)的亲水凝胶骨架缓释片提供有益参考经验。

精密称取聚氧乙烯适量(表1)置800 mL烧杯中,加入125 mL无水异丙醇,高速搅拌(300~400 r·min-1)使分散均匀,加入(576±5) g去离子水,继续高速搅拌1 min(应避免溶液的溅出),然后缓慢搅拌(60 r·min-1)3 h至溶液无肉眼可见胶状物或浑浊(以适当的方式防止水的挥发)。将溶液在水浴中放置30 min,使溶液的温度维持在(25±0.1) ℃,采用旋转黏度计测定,转子和转速见表1
聚氧乙烯的粒径采用Mastersizer 3000粒度测定仪测得。测定参数为:样品量约3 g,喷射压力0.3 MPa,饲料速度50%,载体折射率1.0,测定时间10 s每个样品测定3次以平均值报告D10,D50和D90值。
聚氧乙烯的松密度和振实密度采用PT-TD堆密度测定仪测定,根据测得的密度值计算卡尔指数和豪斯纳比。卡尔指数[carr index%=(振实密度-松密度)/振实密度×100%)]在5%~15%意味着良好的流动性,大于23%则表示流动性差。豪斯纳比(hausner ratio=振实密度/松密度)低于1.2表示较好的流动性,大于1.5表示粉体流动性较差[4-5]。粉体休止角采用GTB-01A粉体流动性测定仪测得,一般来说粉体休止角小于40°即可满足生产过程中的流动性需求。
将待测样品粉末置于DSC的测试铝盘中,以氧化铝为参比物,在氦气吹扫(40 mL·min-1)下,从30 ℃升温至200 ℃,以10 ℃·min-1的升温速率进行升温扫描。
聚氧乙烯 WSR N60K不同用量时的米拉贝隆缓释片处方见表2。为了消除制粒工艺差异对缓释片释放度的影响,片剂采用直接压片法制备。除硬脂酸镁外,所有原辅料用三维混合器混合15 min,然后加入硬脂酸镁混合2 min。最终混合物用旋转压片机压成12 mm×6 mm的浅凸片剂,片剂硬度控制在100~120 N范围内,片剂质量约250 mg。
不同促渗透剂的米拉贝隆缓释片处方见表3。根据米拉贝隆缓释片原研专利[6], 片剂中加入不同相对分子质量的PEG、聚维酮、糖醇、糖或其他水溶性物质,可以保证水分渗透到片剂中。本研究对PEG4000、PEG8000和乳糖进行了比较研究。片剂制备方法同“2.5”项下所述。
根据相对分子质量的不同,聚氧乙烯分成一系列规格。本研究比较了聚氧乙烯 WSR N12K (相对分子质量约为1 000 000)、聚氧乙烯 WSR N60K (相对分子质量约为2 000 000) 和聚氧乙烯 WSR 301 (相对分子质量约为4 000 000)对药物释放的影响。同时比较了聚氧乙烯 WSR N60K和聚氧乙烯 WSR N12K-301(65∶35)混合物(与N60K具有相同黏度)制得的片剂的释放度。不同相对分子质量聚氧乙烯的米拉贝隆缓释片处方见表4。片剂制备方法同“2.5”项下所述。
将聚氧乙烯WSR N60K筛分成以下不同粒径的样品:<75、75~125、125~180 μm和>180 μm。按照”2.5”项下F2处方和工艺分别制备米拉贝隆缓释片,考察粒径对药物释放度的影响。
米拉贝隆缓释片的释药参照文献[7]中的释药方法进行。采用篮法,转速100 r·min-1,分别采用去离子水、pH 4.5醋酸-乙酸钠缓冲液、pH 6.8磷酸盐缓冲液、pH 1.2盐酸溶液作为溶解介质。采用Sotax在线溶出度测定仪测定。
采用相似因子f2评价不同处方间溶出曲线的相似性,f2的计算见公式1。
f2=50log 1 + 1 n t = 1 n ( R t - T t ) 2 - 0.5 × 100 %
其中n为取样时间点个数, Rt为参比样品(或变更前样品)在t时刻的溶出度,Tt为试验批次(变更后样品)在t时刻的溶出度。50<f2<100时表示两条溶出曲线具有相似性[8]
聚氧乙烯容易发生自氧化,导致链断裂,相对分子质量和黏度下降,因此,一般通过添加抗氧化剂如丁基羟基甲苯(BHT)来稳定PEO产品 [2,9-11]。在本研究中,为了评价缓释片中BHT对药物释放的影响,制备了不同用量BHT的米拉贝隆缓释片(表5),在加速实验条件下(40 ℃, 75% RH)进行稳定性实验。
聚氧乙烯 N12K,N60K,301和301-N12K(35∶65)具有相似的粒径分布,见表6。聚氧乙烯301-N12K(35∶65)与聚氧乙烯 WSR N60K黏度接近。
各规格聚氧乙烯的密度,卡尔指数和休止角近似,见表7。从卡尔指数和休止角可以看出,所有聚氧乙烯均具有较好的流动性。
米拉贝隆原料的熔点为144~146 ℃,表明该原料为α晶型,根据专利[12],只有α晶型米拉贝隆是稳定的,是可以用于药物制剂原料的(图1)。米拉贝隆缓释片(RLD)和实验室制备的F2处方片具有相似的DSC曲线,曲线中原料药的熔点峰消失了,主要原因可能是聚氧乙烯和PEG的熔点均较低(在60~70 ℃左右),在DSC升温过程中,当温度升高至聚氧乙烯和PEG的熔点以上时,米拉贝隆溶解在该混合溶液中,故检测不到原料熔点峰。
聚氧乙烯 N60K用量为28%时制得的片剂与RLD在4种介质中均具有相似的释放度(f2>50)(图2,表8)。而聚氧乙烯 N60K用量为20%时,米拉贝隆释放度偏快,用量为36%时,米拉贝隆释放度偏慢。
本研究所采用的3种促渗透剂PEG4000, PEG8000和乳糖制得的片剂均具有与RLD具有相似的释放度(f2>50)(图3,表9)。
低相对分子质量的聚氧乙烯 WSR N12K 得到较快的溶出度,而高相对分子质量的聚氧乙烯 WSR 301 获得较慢的溶出度(图4,表10)。而聚氧乙烯 WSR N60K和聚氧乙烯 WSR 301-N12K(35∶65)混合物制得的片剂均具有与RLD相似的释放度(f2>50)。同时,聚氧乙烯 WSR N60K与聚氧乙烯 WSR 301-N12K混合物制得片剂在不同介质中的溶出曲线相似因子分别为 61.3(pH 6.8),51.7(水),63.3(pH 4.5)和 80.6(pH1.2),均大于50。
各筛分粒径聚氧乙烯 N60K制得的片剂与未筛分样品制得的片剂均具有相似的释放度(f2>50)(图5,表11)。
值得注意的是,虽然本研究中聚氧乙烯的粒径对米拉贝隆缓释片的释放度无显著影响,但是,聚合物黏度会随着粒径分布的变化而变化(图6)。粒径越细,聚合物黏度越低。
不同BHT用量所得米拉贝隆缓释片的加速稳定性实验结果见图7,各处方加速实验6月后的溶出度曲线与0月相比,相似因子f2均大于50(BHT用量为0.16%、0.048%、0时,f2分别为59.4、55.4和52.4)。但是,我们也需要注意,在加速稳定性试验条件下时,药物溶出度有随时间变快的趋势,为了保证稳定性,使用聚氧乙烯制备缓释骨架片可以适量加入BHT。
本研究以米拉贝隆为模型药,聚氧乙烯为亲水凝胶骨架材料制备缓释片。考察了聚氧乙烯的相对分子质量、粒径和用量,BHT含量和促渗透剂种类对米拉贝隆缓释片释放度的影响。
结果表明,聚氧乙烯的相对分子质量和用量对米拉贝隆的释放有重要影响。聚氧乙烯 N60K用量在28%时制得片剂药物释放度与RLD相似,用量较高时药物释放度较慢,而用量低时药物释放速度较快。高相对分子质量聚氧乙烯 WSR 301导致较慢的药物释放度,而低相对分子质量聚氧乙烯 N12K释药较快。聚氧乙烯 WSR 301和N12K以35∶65的比例混合,可以获得与聚氧乙烯 WSR N60K相同的溶液黏度,制得的片剂具有统计上相似的药物释放曲线。研究的3种促渗透剂, PEG 8000,PEG4000和乳糖,均得到与RLD相似的溶出度。
在研究条件下,聚氧乙烯WSR N60K的各筛分粒径对米拉贝隆释放度无显著影响,各筛分粒径制得的片剂获得未筛分样品相似的溶出曲线。但值得注意的是,聚氧乙烯黏度受粒径分布的影响,筛分得到的粒径越细的样品,黏度越低,也意味着相对分子质量越低。这也表明,对米拉贝隆缓释片而言, 基于聚氧乙烯的处方较稳健,即使黏度在较大范围波动也可获得相似溶出度。
稳定性实验表明,经加速稳定性实验6个月后,不同BHT用量制备的缓释片的溶出曲线均与0月相似,但是加入适量BHT更利于维持产品稳定性。
