目的
2
探究在缺血性脑卒中(CIS)病理状态下,右莰醇对大鼠体内依达拉奉药代动力学参数的影响。
方法
2
将20只雄性SD大鼠随机分为依达拉奉组和依达拉奉右莰醇注射用浓溶液(EDB注射液)组,每组10只。采用改良Longa线栓法构建大鼠大脑中动脉阻塞(MCAO)模型,缺血再灌注5 min内尾静脉注射相应药液,给药剂量均为2.5 mg/kg(以依达拉奉计)。分别于注射后0.08、0.5、1、3、6、18、24 h从大鼠眼眶静脉丛采集血液,以卡马西平为内标,采用超高效液相色谱-串联质谱(UPLC-MS/MS)法测定大鼠体内依达拉奉的血药浓度,以DAS软件计算药代动力学参数并进行比较。
结果
2
与依达拉奉组比较,EDB注射液组大鼠体内依达拉奉的峰浓度(
c
max
)显著升高(
P
<0.05),半衰期、达峰时间、清除率及曲线下面积差异均无统计学意义(
P
>0.05)。
结论
2
在CIS病理状态下,右莰醇可升高依达拉奉在模型大鼠血浆中的
c
max
,但对依达拉奉的全身暴露量与清除能力无明显影响。
OBJECTIVE
2
To investigate the effects of dexborneol on the pharmacokinetic parameters of edaravone in rats under the pathological condition of cerebral ischemic stroke (CIS).
METHODS
2
Twenty male SD rats were randomly divided into the edaravone group and the Edaravone and dexborneol concentrated solution for injection (EDB injection) group, with 10 rats in each group. A middle cerebral artery occlusion (MCAO) rat model was established using the modified Longa suture method. Within 5 min of ischemia-reperfusion, the corresponding drug solutions were injected via the tail vein at a dose of 2.5 mg/kg (calculated by edaravone). Blood samples were collected from the orbital venous plexus at 0.08, 0.5, 1, 3, 6, 18, and 24 h after injection. With carbamazepine as the internal standard, the plasma concentration of edaravone was determined by ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) method. Pharmacokinetic parameters were calculated using DAS software and compared between the two groups.
RESULTS
2
Compared with the edaravone group, the peak concentration (
c
max
) of edaravone in the EDB injection group was significantly increased (
P
<0.05), while no statistically significant differences were observe
d in the half life, time to peak, clearance, or area under curve (
P
>0.05).
CONCLUSIONS
2
Under the pathological condition of CIS, dexborneol can increase the
c
max
of edaravone in the plasma of model rats, but has no significant effect on the systemic exposure or clearance of edaravone.
