Ceftolozane contains a 7-aminothiadiazole, affording increased activity against gram-negative organisms, as well as an alkoximino group, providing stability against many β-lactamases. Ceftolozane has a dimethylacetic acid moiety that contributes to enhanced activity against Pseudomonas aeruginosa. The addition of a bulky side chain (a pyrazole ...
ATC code J01 Antibacterials for systemic use is a therapeutic subgroup of the Anatomical Therapeutic Chemical Classification System, a system of alphanumeric codes developed by the World Health Organization (WHO) for the classification of drugs and other medical products.
It retains some activity of later-generation cephalosporins having broad-spectrum activity against Gram-negative bacteria, but its effectiveness is relatively much weaker. [4] [5] It is currently being investigated for community-acquired pneumonia [6] and complicated skin and skin structure infection. [7] [8] [9]
Gram-negative: Third-generation cephalosporins have a broad spectrum of activity and further increased activity against gram-negative organisms. They may be particularly useful in treating hospital-acquired infections , although increasing levels of extended-spectrum beta-lactamases are reducing the clinical utility of this class of antibiotics.
Tazobactam is a pharmaceutical drug that inhibits the action of bacterial β-lactamases, especially those belonging to the SHV-1 and TEM groups. It is commonly used as its sodium salt, tazobactam sodium.
The basic structure of first generation cephalosporins. First generation cephalosporins were the first cephalosporins on the market. They have good antimicrobial activity against gram-positive bacteria but limited activity against gram-negative species. [25] The chemical structures of the first generation cephalosporins are fairly simple.
Cefpodoxime is an oral, third-generation cephalosporin antibiotic available in various generic preparations. It is active against both Gram-positive and Gram-negative organisms with notable exceptions including Pseudomonas aeruginosa, Enterococcus, and Bacteroides fragilis.
The main classes of β-lactam antibiotics used to treat gram-negative bacterial infections include (in approximate order of intrinsic resistance to cleavage by β-lactamases) penicillins (especially aminopenicillins and ureidopenicillins), 3rd generation cephalosporins, and carbapenems.
