製品説明 | Ceftriaxone disodium salt hemi (heptahydrate) is a third-generation cephalosporin antibiotic. |
---|---|
in vitro | Ceftriaxone disodium salt hemi(heptahydrate) is a third-generation cephalosporin antibiotic has a broad spectrum of activity in vitro which includes Gram-positive and Gram-negative aerobic and some anaerobic bacteria. Both penicillin-sensitive and –resistant strains of Staphyococcus aureus are sensitive to Ceftriaxone (MIC90, 2 to 8 mg/L), but the drug is poorly active against methicillin- or oxacillin-resistant strains. Creftriaxone is similar in activity to several penicillins and other cephalosporins against Streptococcus pyogenes, and is also active in low concentrations against other Streptococcus species. Staphylococcus epidermidis is only moderately sensitive and Streptococcus faecalis is usually resistant to Ceftriaxone. Ceftriaxone is generally more active than cefoperazone, and is similar in activity to cefotaxime and latamoxef against Gram-negative bacilli. 90% of tested strains of most Enterobacteroacae are inhibited by a Ceftriaxone concentration of < 1 mg/L. The reported activity of Ceftriaxone against Pseudomonas aeruginosa varies widely, but generally at least 32 mg/L is required to inhibit most strains, and is thus usually less active than the aminoglycosides, aztreonam, imipenem, cefoperazone, ceftazidime, carumonam and piperacillin. |
