静滴青霉素 G 具有见效快,作用迅速,强大等特点,故临床上广泛使用。青霉素 G 钠或钾盐的水溶液极不稳定,H~+、OH~-、重金属离子、氧化剂、醇和温度均能催化它的分解,室温中势价迅速下降,由于5％葡萄糖注射液的 pH 为3.2～5.5,故有人认为用5％葡萄糖稀释作静脉滴注就不恰当,而用0.9％氯化钠注射液(pH 4.5～ Intravenous penicillin G with quick, rapid, powerful and so on, it is widely used in clinical practice. Penicillin G sodium or potassium aqueous solution is very unstable, H ~ +, OH ~ -, heavy metal ions, oxidants, alcohol and temperature can catalyze its decomposition, the room temperature in the rapid decline in potential valence, the 5% glucose injection pH = 3.2 ~ 5.5, so some people think that with 5% glucose for intravenous infusion is not appropriate, but with 0.9% sodium chloride injection (pH 4.5 ~
