青霉素、链霉素是临床上应用较广的两种抗菌素,且常联合应用。为了探索青霉素与链霉素溶液混合后,相互之间对稳定性有无影响,我们进行了初步的实验研究。方法是将青霉素G钾和硫酸链霉素分别用注射用水溶解,并各取一定量按临床习惯配比混合,得青霉素、链霉素及青、链霉素混合溶液。以分光光度法分别测定这三种样品溶液中青 Penicillin, streptomycin is widely used in clinical two antibiotics, and often combined application. In order to explore the penicillin and streptomycin solution mixed with each other whether the stability of the impact, we conducted a preliminary experimental study. The method is to dissolve penicillin G potassium and streptomycin respectively with water for injection, and take a certain amount according to the clinical mix proportion to obtain penicillin, streptomycin and cyanine and streptomycin mixed solution. The three sample solutions were determined spectrophotometrically
