本文将氨苄青霉素钠与氨茶碱注射液在0.9%氯化钠注射液中配伍实验,从物理变化方面观察4h,外观无变化。混合后不同时间测其pH值,略有下降。从化学变化方面,经过4h的紫外测定,单独组与混合组中的氨茶碱在274nm处的吸收值基本不变,其氨茶碱青霉素钠在325nm的吸收值略有下降,但P0.
In this paper, ampicillin sodium and aminophylline injection in 0.9% sodium chloride injection compatibility experiments, observed from the physical changes in 4h, the appearance of no change. Measured at different times after mixing its pH, a slight decline. From the chemical changes, after 4h UV determination, aminophylline alone group and mixed group at 274nm at the same absorption value, its ammonia theophylline penicillin sodium absorption at 325nm decreased slightly, but P0.
