(一)青霉素(Penicillin)青霉素钾、钠盐应用于临床已三十年,但仍不失为控制敏感金葡菌、链球菌、肺炎双球菌等所引致的严重感染如败血症、肺炎、脑膜炎、心内膜炎等疾病的一个有效武器,和链霉素联合应用更可取得协同作用。以敏感的革兰氏阳性球菌所引起的感染而言,青霉素钾、钠盐常是首选药物,其疗效胜过四环素、氯霉素、苯甲异(口恶)唑青霉素、先锋霉素、卡那霉素、庆大霉素等。某些医疗单位反映,大剂量青霉素静脉滴注对某些革兰氏阴性杆菌如大肠杆菌、变形杆菌、绿脓杆菌等所引起的严重感染有时也有效。
(A) of Penicillin Penicillin potassium, sodium salt has been used for 30 years in clinical trials, but still can be controlled by the control of sensitive Staphylococcus aureus, Streptococcus pneumoniae and other serious infections such as sepsis, pneumonia, meningitis, heart Endocarditis and other diseases an effective weapon, and streptomycin can be synergistic synergistic effect. Penicillin potassium and sodium salts are often the drug of choice for infections caused by sensitive Gram-positive cocci, and are more potent than tetracycline, chloramphenicol, benzathine, cephamycin, Natamycin, gentamicin and the like. Some medical units have reported that intravenous infusion of large doses of penicillin is also sometimes effective against some Gram-negative bacilli such as Escherichia coli, Proteus, Pseudomonas aeruginosa and other serious infections.
