Objective:

To establish a principal component external standard method with HPLC and calibration factors for the determination of 11 impurities in flurbiprofen axetil injection, and to explore its detection results and limit values.

Methods:

The Thermo BDS Hypersil C18 (250×4.6 mm, 5 μm) was selected for gradient elution, with water-0.15% acetic acid and acetonitrile-0.15% acetic acid as the mobile phase at a flow rate of 1.0 mL·min-1. The column temperature was 40 ℃, the detection wavelength was 254 nm and the injection volume was 10 μL.

Results:

Flurbiprofen axetil and 11 impurities were well separated by the method. Good linearity was obtained with correlation coefficients of 1.000 for the 3-fluoro-4-phenylphenol (4-OHB), 1-acetoxyethyl-2-(2-fluoro-4-biphenylyl)-2-hydroxypropionate (2-OHP), 4-acetyl-2-fluorobiphenyl (4-ACB), flurbiprofen ethyl ester, allyl -(2-fluoro-4-biphenyl) propionate (ALE), ChP impurityⅠ , impurity B, impurity C and impurity E in the range of 0.10-20 μg·mL-1. The average recovery rates was from 96.6% to 103.7% and the relative standard deviations(RSDs) were lower than 1.4%. The correction factors of flurbiprofen axetil related substances 4-OHB, 2-OHP,4-ACB, flurbiprofen, flurbiprofen ethyl ester, ALE, ChP impurity Ⅰ, impurity B, impurity C and impurity E were 0.55, 1.05, 1.01, 0.76, 0.95, 0.86, 0.55, 0.93, 0.76 and 0.81, respectively. Notablely, desfluoro fiurbiprofen axetil of detected was around the prescribed limit 0.1%.

Conclusion:

The method above is rapid, simple, accurate, and reliable, and can be applied for the determination and quality control of related substances in flurbiprofen axetil injection.

Objective:

To establish a principal component external standard method with HPLC and calibration factors for the determination of 11 impurities in flurbiprofen axetil injection, and to explore its detection results and limit values.

Methods:

The Thermo BDS Hypersil C18 (250×4.6 mm, 5 μm) was selected for gradient elution, with water-0.15% acetic acid and acetonitrile-0.15% acetic acid as the mobile phase at a flow rate of 1.0 mL·min-1. The column temperature was 40 ℃, the detection wavelength was 254 nm and the injection volume was 10 μL.

Results:

Flurbiprofen axetil and 11 impurities were well separated by the method. Good linearity was obtained with correlation coefficients of 1.000 for the 3-fluoro-4-phenylphenol (4-OHB), 1-acetoxyethyl-2-(2-fluoro-4-biphenylyl)-2-hydroxypropionate (2-OHP), 4-acetyl-2-fluorobiphenyl (4-ACB), flurbiprofen ethyl ester, allyl -(2-fluoro-4-biphenyl) propionate (ALE), ChP impurityⅠ , impurity B, impurity C and impurity E in the range of 0.10-20 μg·mL-1. The average recovery rates was from 96.6% to 103.7% and the relative standard deviations(RSDs) were lower than 1.4%. The correction factors of flurbiprofen axetil related substances 4-OHB, 2-OHP,4-ACB, flurbiprofen, flurbiprofen ethyl ester, ALE, ChP impurity Ⅰ, impurity B, impurity C and impurity E were 0.55, 1.05, 1.01, 0.76, 0.95, 0.86, 0.55, 0.93, 0.76 and 0.81, respectively. Notablely, desfluoro fiurbiprofen axetil of detected was around the prescribed limit 0.1%.

Conclusion:

The method above is rapid, simple, accurate, and reliable, and can be applied for the determination and quality control of related substances in flurbiprofen axetil injection.

氟比洛芬酯作为非甾体抗炎药物(nonsteroidal antiinflammatory drugs,NSAIDs)[1],可非选择性地抑制环氧合酶,阻断前列腺素合成,从而发挥镇痛、抗炎、解热作用。氟比洛芬酯注射液是由卵磷脂包封的氟比洛芬酯脂微球[2-5],进入体内后可靶向分布于创伤和肿瘤组织,在羧酸酯酶作用下水解生成氟比洛芬而发挥镇痛作用,目前临床上常用于缓解术后及因癌症引起的疼痛[6-10]。近年来,有文献报道氟比洛芬酯注射液在临床应用过程中出现不良反应(adverse drug reaction,ADR)或镇痛效果不佳[11-12],而药物的安全性、有效性与原辅料的质量控制、制剂处方工艺息息相关。目前,氟比洛芬酯注射液杂质检测的文献不多[10],且仅检测杂质氟比洛芬,未见有测定其他杂质的报道;另一方面,氟比洛芬酯注射液国内现行质量标准[13-14]的有关物质检验方法对已知杂质的检验也仅限于氟比洛芬,缺乏对其他已知杂质的全面监测,存在专属性、准确度等方面的缺陷,对杂质的监测把控严重不足。因此,亟需建立专属性更强,准确度更高的有关物质检测方法,提高用药安全性。本文通过查阅文献[15-18],确定合成过程中引入的起始物料、中间体或副产物及降解过程中可能产生的相关杂质,并结合当前市场可获得的杂质对照品,对氟比洛芬酯注射液杂质进行深度研究,建立能同时测定其11个有关物质的HPLC法,并进行了详细的方法学验证,旨在提高氟比洛芬酯注射液的安全性,对有关物质进行严格、全面和精确的质量控制研究,实现了对该制剂中有关物质的有效分离和准确定量。

氟比洛芬酯及其杂质对照品:氟比洛芬酯(含量99.8%)、氟比洛芬(含量99.7%)、《中华人民共和国药典》(ChP)杂质Ⅰ(含量100%),中国食品药品检定研究院;2-氟-4-羟基联苯(4-OHB,含量98.13%)、4-乙酰基-2-氟联苯(4-ACB,含量97.62%)、1-乙酰氧基-2-(2-氟-4-联苯)-2-羟基丙酸酯(2-OHP,含量97.73%)、烯丙基-(2-氟-4-联苯)丙酸酯(ALE,含量99.86%)、氟比洛芬乙酯(含量99.56%)、杂质B(含量96.02%)、杂质C(含量99.14%)、杂质E(含量98.14%),深圳市恒丰万达医药科技有限公司;色谱级乙腈、甲醇购自Merck公司,冰醋酸(纯度>99%)购自Fisher公司;实验用18.2 MΩ·cm纯化水由Millipore Milli-Q Advantage A10超纯水系统(密理博公司)制得。73批氟比洛芬酯注射液(规格5 mL:50 mg),国内A、B 2家生产企业。
采用Thermo BDS Hypersil C18(250 mm×4.6 mm,5 μm)色谱柱,以含0.15%冰醋酸水溶液(A)-含0.15%冰醋酸乙腈(B)为流动相,梯度洗脱(0~20.0 min,40%B→47%B;20.0~24.0 min,47%B→60%B;24.0~37.5 min,60%B;37.5~38.0 min,60%B→40%B;38.0~48.0 min,40%B),流速1.0 mL·min-1,柱温40 ℃,检测波长254 nm,进样量10 μL。
含0.15%冰醋酸水溶液(A)-含0.15%冰醋酸乙腈(B)(67.5:3 2.5)。
分别取氟比洛芬和氟比洛芬酯的对照品适量,精密称定,加无水乙醇分别制成每1 mL含1 mg的溶液,即得。
取本品适量,用稀释剂稀释成每1 mL中约含氟比洛芬酯1 mg的溶液,即得。
分别取各杂质(4-OHB、2-OHP、4-ACB、氟比洛芬乙酯、氟比洛芬、ALE、ChP杂质Ⅰ、杂质B、杂质C、杂质E)对照品适量,精密称定,分别加无水乙醇溶解并制成浓度约为1 mg·mL-1的溶液,即得。
精密量取样品1 mL,置10 ml量瓶中,分别加入“2.2.4”项下氟比洛芬储备液0.74 mL、其他各杂质储备液10 μL,用稀释剂溶解并稀释至刻度,摇匀,即得。
分别取“2.2.2”“ 2.2.4”项下各溶液适量,用稀释剂稀释成质量浓度均约为0.05、0.1、0.2、0.5、1、5、10、20、50、100 μg·mL-1的系列对照品溶液,即得。
分别取稀释剂和系统适用性溶液,按照“2.1”项色谱条件进样测定。色谱图见图1。如图1可见,本方法的专属性良好,各杂质与主成分间分离度均符合要求(氟比洛芬酯存在RS异构体,在计算含量时选择2个异构体峰面积加和计算)。
取“2.2.6”项下质量浓度约为0.1 μg·mL-1的4-OHB、2-OHP、4-ACB、氟比洛芬、氟比洛芬乙酯、ALE、ChP杂质Ⅰ、杂质B、杂质C、杂质E的线性溶液,逐级稀释,按S/N≈10时的质量浓度作为定量限,S/N≈3时的质量浓度作为检出限,并计算浓度。结果见表1
分别取“2.2.6”项下混合线性溶液,按照“2.1”项条件操作。分别将氟比洛芬酯及各杂质的浓度对应峰面积进行线性回归,以氟比洛芬酯线性斜率与各杂质线性斜率的比值计算杂质的校正因子,并计算相对保留时间。化合物在各自浓度范围内线性关系良好,r均为1.000,详细结果见表1。杂质对照品溶液色谱图如图2所示。
按“2.2.5”项下方法配制6份溶液,即得加样回收率试验用供试品溶液;按“2.2.3”项下方法配制1份供试品溶液。按“2.1”项下条件操作,测定各杂质峰面积,计算结果显示各杂质的回收率均在96.6%~103.7%。取质量浓度约为1 μg·mL-1的对照品溶液作为4-OHB、2-OHP、4-ACB、氟比洛芬酯、氟比洛芬乙酯、ALE、ChP杂质Ⅰ、杂质B、杂质C、杂质E的系统精密度试验用供试品溶液,取质量浓度约为10 μg·mL-1的对照品溶液作为氟比洛芬的系统精密度溶液,连续进样6次,记录色谱图,计算各化合物峰面积的RSD均在0.14%~0.59%。表明方法的准确度与精密度良好。
将液相色谱仪柱温分别调整为35、45 ℃,流速分别调整为0.9、1.0 mL·min-1,色谱图峰形基本不变,色谱保留时间发生微小改变,理论塔板数和分离度基本不变,各化合物之间分离度均大于1.5。结果表明,测定条件微小变动能满足系统适用性试验要求,不影响各化合物的检测,方法可靠。
取A、B 2家国内企业生产的样品共计73批次,分别按“2.2.2”项下方法制备供试品溶液,按“2.1”项下条件测定,按加校正因子的主成分外标法计算,结果如表2所示。上述各杂质检出量均符合拟定限度规定[14](氟比洛芬不得过0.74 mg·mL-1,其他单个杂质不得过0.1%)。
按照拟定方法检验,在供试品溶液色谱图中相对保留时间0.98处检出一新的未知杂质峰(图3-A),但该杂质若采用YBH00382018[14]中“其他杂质”项的方法则无法有效分离和检出(图3-B)。在全部73批次样品中均检出该杂质,暂且按校正因子为1.0计算后检出值处于较高的水平,因此有必要对该杂质进行结构解析,推断其化学结构式。
采用UHPLC-HRMS高分辨质谱技术对该杂质进行结构解析。首先通过采集高分辨一级质谱图和二级质谱图,获取该杂质的准分子离子和碎片离子的高精度质谱信息,采用Xcalibur软件进行元素组成分析和同位素分布比对,得知分子式可能为C19H20O4,与主成分氟比洛芬酯相比少了1个F原子,初步推测为脱氟产物(以下称氟比洛芬酯脱氟物)。将氟比洛芬酯脱氟物结构式和实测二级质谱图导入MassFrontier软件,进行计算、模拟、匹配、分析,进而验证其结构式推导正确,初步确认该化合物为氟比洛芬酯脱氟物[化学名:乙酰氧基乙基2-(4-联苯基)丙酸酯;CAS号:1685278-08-3]。

国内2家主要生产单位现执行的质量标准中,仅1家对有关物质进行检测,即对氟比洛芬及未知单个杂质进行监控。在对有关物质相关杂质展开深度研究过程中,发现采用原色谱条件[乙腈-水-冰醋酸(675:325:1.5)]并不能实现多种杂质的良好分离,系统适用性较差。在优化色谱条件方面,考察了不同流动相体系,结果表明0.15%冰醋酸水溶液-0.15%冰醋酸的乙腈系统分离效果较好。本实验测定的11个有关物质中,存在杂质数量多,极性分散,且部分杂质极性接近等困扰。为提高系统分离效果,缩短分析时间,通过筛选不同类型色谱柱、调整洗脱条件,最终确定选用C18色谱柱(Thermo BDS Hypersil,250 mm×4.6 mm,5 μm)和梯度洗脱程序。结果显示系统适用性良好,各已知杂质与主成分之间得到良好分离,进而实现了对多种已知杂质的定性、定量分析。
2家企业样品中检出量最高的已知杂质均为氟比洛芬,总体上氟比洛芬检出量均值较为接近,但B企业25%~75%分位数以及1.5 IQR(内距,四分位差)明显优于A企业,表明B企业检出量集中在均值附近,数据离散度较小。因此,B企业中杂质氟比洛芬含量的批间均一性较稳定,氟比洛芬酯注射液生产工艺控制更好,批次间氟比洛芬检出量离散度显著低于A企业样品,见图4(红色为A企业,蓝色为B企业)。除氟比洛芬之外,样品中检出量最大的已知杂质为2-OHP,全部73批次样品中均检出且检出量均不低于0.02%;A企业仅有6批次样品检出4-ACB杂质且检出量很低,均为0.002%,相对而言,B企业32批次样品中均检出4-ACB,结果介于0.01%~0.04%;此外,2家企业样品中的氟比洛芬乙酯、ALE、杂质B、杂质C、ChP杂质Ⅰ、检出量都处于极低的水平(<0.01%),A企业41批次样品中其他最大单个杂质检出量介于0.03%~0.05%,B企业32批次样品中其他最大单个杂质检出量在0.02%~0.03%范围内;A企业41批次样品中氟比洛芬酯脱氟物检出量介于0.06%~0.13%,有10批次样品超过了0.1%的拟定限度,不合格率为24.4%;B企业32批次样品检出量在0.11%~0.18%范围内,均超过了0.1%的拟定限度,不合格率为100%。氟比洛芬酯脱氟物测定结果频数分布图及箱式图详见图5。数据密集分布在0.08%~0.10%以及0.12%~0.14% 2个区间内。氟比洛芬酯脱氟物检出量以0.11%为中心呈正态分布,数据在0.08%~0.10%以及0.12%~0.14% 2个区间内较为集中。统计结果显示,2家企业数据的25%~75%分位数、1.5 IQR差异不大,表明2家企业数据的离散度相当,但B企业的均值为0.14%,显著高于A企业0.09%的水平。A企业41批次样品中除氟比洛芬外的各杂质总和介于0.18%~0.31%,B企业32批次样品在0.24%~0.35%范围内,见图6
本文通过对氟比洛芬酯注射液有关物质进行对照品定位,从而计算各杂质相对保留时间对供试品中杂质进行定性,并建立了1种加校正因子的主成分外标法对氟比洛芬酯注射液有关物质的杂质定量分析。该方法无须杂质对照品即可对供试品中多种已知杂质进行定性定量分析,快速简便、灵敏度高、专属性强、准确可靠,为氟比洛芬酯注射液生产过程控制及质量监控提供了技术支撑。与此同时,目前国内氟比洛芬酯的合成工艺大多以氟比洛芬作为起始原料[18],氟比洛芬结构中包含氟原子,且通常C-F键合较为稳定。因此氟比洛芬脱氟物杂质极为可能是在原料药合成过程中产生,即原料药氟比洛芬酯的副产物。以上结果提示2家企业均应进一步提高原料药生产工艺,尽可能减少氟比洛芬酯脱氟物杂质的产生,建议将产品中该杂质的检出量控制在合理限度之内。与此同时,未来我们将进一步通过氟比洛芬酯脱氟物杂质对照品进行定位确认及校正因子测定,从而更加完善测定方法,确保试验结果的准确性。
