The pharmacokinetics of Cytarabine Polybutylcyanoacrylate Nanoparticles (Ara-C-PBCA-NP) lyophilization injection in rabbits was studied.
Ara-C water solution was taken as reference, the concentration of Ara-C was determined by HPLC, and the pharmacokinetic parameters were calculated.
Pharmacokinetic properties of Ara-C water solution and Ara-C-PBCA-NP lyophilization injection complied with two-department model. The parameters t1/2 beta and MRT of Ara-C-PBCA-NP lyophilization injection were prolonged, and CL was reduced dramatically (P < 0.05).
Ara-C-PBCA-NP lyophilization injection possesses prolonged retention time in vivo and significant sustained releasing character.
研究阿糖胞苷聚氰基丙烯酸丁酯纳米粒(Ara-C-PBCA-NP)冻干注射剂在兔体内的药代动力学。
以阿糖胞苷水溶液为对照,采用高效液相色谱法测定阿糖胞苷浓度,并计算药代动力学参数。
阿糖胞苷水溶液和阿糖胞苷-PBCA-NP冻干注射剂的药代动力学性质均符合二室模型。阿糖胞苷-PBCA-NP冻干注射剂的t1/2β和MRT参数延长,CL显著降低(P<0.05)。
阿糖胞苷-PBCA-NP冻干注射剂在体内具有较长的滞留时间和显著的缓释特性。
