TITLE:
摘要: 目的:考察左乙拉西坦(Lev)注射液与3种注射液的配伍稳定性。方法:取Lev注射液各1 000 mg分别与0.9%氯化钠注射液100 mL、5%葡萄糖注射液100 mL和乳酸钠林格注射液100 mL配伍,在25 ℃未避光条件下,分别于配制后24 h不同时间点观察各配伍液的颜色和澄清度,测定其pH值和不溶性微粒数,并采用高效液相色谱法测定各配伍液中相关杂质(杂质A、B、C、D和2-羟基吡啶)和Lev的含量。结果:在上述条件下,各配伍液在24 h内均为无色澄清液体,pH值无明显变化(RSD<1%,n=7),不溶性微粒数均未超出2015年版《中国药典》规定的范围;未检出杂质B和杂质C,其余杂质的含量均符合国外各药典的限度要求;Lev的相对百分含量无明显变化(RSD<1%,n=7)。结论:Lev注射液与0.9%氯化钠注射液、5%葡萄糖注射液和乳酸钠林格注射液配伍后,在25 ℃未避光条件下24 h内保持稳定。
ABSTRACT: OBJECTIVE: To investigate the compatible stability of Levetiracetam (Lev) injection with 3 injections. METHODS: Each Lev injection 1 000 mg mixed with 0.9% Sodium chloride injection 100 mL, 5% Glucose injection 100 mL or Sodium lactate Ringer’s injection 100 mL respectively. Under the light condition, at 25 ℃, the color and clarification degree of mixtures were observed at different time points within 24 h after mixing; pH value and the number of insoluble particles were determined. The contents of related impurities (impurity A, B, C, D, 2-hydroxypyridine) and Lev in mixtures were determined by HPLC. RESULTS: Under above condition, all mixtures were colorless clear liquid within 24 h; pH value had no significant change (RSD<1%,n=7); the number of insoluble particles was no more than the range stated in Chinese Pharmacopeia (2015 edition). Impurity B and C were not detected; the contents of other impurities were in line with the requirements of foreign pharmacopeia. No marked change was noted for relative content of Lev (RSD<1%,n=7). CONCLUSIONS: After mixing with 0.9% Sodium chloride injection, 5% Glucose injection or Sodium lactate Ringer’s injection, Lev injection keep stable at 25 ℃ within 24 h under the light condition.
