作者对磷酸氯洁霉素与头孢唑肟钠,头孢西丁钠,头孢孟多甲酸酯钠或头孢唑啉钠中的一种混合后制成的注射液的稳定性,进行了研究。上述每种抗生素单独,或将氯洁霉素与四种头孢菌素中的一种制成的混合注射液进行了试验。将抗生素与5％葡萄糖和0.9％氯化钠注射液混合,在混合后1、4、8、12、24和48小时测定抗生素的浓度、pH,并目测外观变化。结果表明,上述抗生素单独在o.9％氯化钠或5％葡萄糖注射液中,48小时后其含 The authors investigated the stability of injections made by mixing clindamycin phosphate with ceftizoxime sodium, cefoxitin sodium, cefotaxime sodium or cefazolin sodium. Each of these antibiotics was tested alone or in a mixture of clindamycin and one of four cephalosporins. Antibiotics were mixed with 5% dextrose and 0.9% sodium chloride injection, antibiotic concentrations, pH were determined at 1, 4, 8, 12, 24 and 48 hours after mixing and visual changes in appearance. The results show that the antibiotics alone in o.9% sodium chloride or 5% glucose injection, 48 hours after its containing
