本文研究了维拉帕米与茶碱在5%葡萄糖注射液中的稳定性。含4.0和0.4mg/ml茶碱的5%葡萄糖注射液与最终浓度为0.1和0.4mg/ml维拉帕米混合,实验数据表明在24h试验期间内,各种混合物均稳定。维拉帕米对照样品的平均pH在0.4和0.1mg/ml时分别是4.80和4.90,茶碱对照样品在4.0和0.4mg/ml的平均pH分别是4.20和4.79。混合后其平均pH分别为4.29和4.37,与原始资
This article studies the stability of verapamil and theophylline in 5% glucose injection. 5% dextrose injection containing 4.0 and 0.4 mg / ml theophylline was mixed with verapamil at final concentrations of 0.1 and 0.4 mg / ml and the experimental data indicated that the various mixtures were stable during the 24h test. The average pH of the verapamil control samples was 4.80 and 4.90 at 0.4 and 0.1 mg / ml, respectively, and the theophylline control samples were 4.20 and 4.79 at 4.0 and 0.4 mg / ml respectively. After mixing, the average pH was 4.29 and 4.37, respectively, with the original capital
