氨苄青霉素为一广谱半合成青霉素,对革兰氏阴性和阳性菌都有抗菌作用,尤对大肠杆菌、流感杆菌、志贸氏菌和一些变形杆菌的抗菌作用较强。临床上常用于某些革兰氏阴性杆菌所引起的尿路感染、呼吸道感染、胆道感染等。由于其毒性低,疗效较好,可用于孕妇、婴儿,近几年来临床较广泛应用。现就应用中常见的几个问题列举如下:一、适应症掌握不准确氨苄青霉素能较好的控制以上细菌所致的感染,但对革兰氏阳性菌的抗菌作用不及青霉素,且本品能被青霉素酶所破坏,对耐药的金葡菌感染和病毒感染无效,对绿脓杆菌也无效。适应症不准确大致
Ampicillin is a broad spectrum of semi-synthetic penicillin, both Gram-negative and positive bacteria have antibacterial effects, especially against Escherichia coli, influenza, Shigella and some Proteobacteria strong antibacterial effect. Clinically used in some Gram-negative bacteria caused by urinary tract infections, respiratory infections, biliary tract infections. Because of its low toxicity, better efficacy, can be used for pregnant women, infants, clinical more widely used in recent years. Now several common problems in the application are listed below: First, the indications Mastery Inaccurate ampicillin can better control the infection caused by the above bacteria, but the antibacterial effect of Gram-positive bacteria less than penicillin, and the product can Destroyed by penicillinase, drug-resistant Staphylococcus aureus infection and virus infection is invalid, Pseudomonas aeruginosa is also invalid. Inaccurate indications
