Cefotiam is a parenteral third-generation cephalosporin antibiotic. It has broad-spectrum activity against Gram-positive and Gram-negative bacteria. As a beta-lactam, its bactericidal activity results from the inhibition of cell wall synthesis via affinity for penicillin-binding proteins.

Medical uses

This drug is indicated for prophylaxis for surgical infection, postoperative infections, bacterial septicaemia, bone and joint infections, cholangitis, cholecystitis, peritonitis, prostatitis, pyelonephritis, respiratory tract infections, skin and soft tissue infections, cystitis, urethritis, and infections caused by susceptible organisms. It does not have activity against Pseudomonas aeruginosa .^{[ citation needed ]}

Dosage

For adults, the dose is up to 6 grams daily by intravenous or intramuscular route in divided doses according to severity of infection. In patients with renal impairment a dose reduction may be needed.^{[ citation needed ]}

Spectrum of bacterial susceptibility

Cefotiam has a broad spectrum of activity and has been used to treat infections caused by a number of enteric bacteria and bacteria responsible for causing skin infections. The following represents MIC susceptibility data for a few medically significant bacteria.

Bacteroides fragilis: - 16 - >128 μg/ml
Clostridium difficile: >128 μg/ml
Staphylococcus aureus: 0.25 - 32 μg/ml

Adverse effects

Side effects include nausea and vomiting, diarrhoea, hypersensitivity reactions, nephrotoxicity, convulsions, CNS toxicity, hepatic dysfunction, haematologic disorders, pain at injection site, thrombophlebitis, pseudomembranous colitis, and superinfection with prolonged use.^{[ citation needed ]}

Mechanism of action

Cefotiam inhibits final cross-linking stage of peptidoglycan production, thus inhibiting bacterial cell wall synthesis. It has similar or less activity against Gram-positive staphylococci and streptococci, but is resistant to some beta-lactamases produced by Gram-negative bacteria. It is more active against many of the Enterobacteriaceae including Enterobacter, E. coli, Klebsiella, Salmonella and indole-positive Proteus species.^{[ citation needed ]}

In clinical use, high concentrations of cefotiam are observed in several tissues (kidney, heart, ear, prostate, and genital tract), as well as in fluids and secretions (bile, ascitic fluid).^{[ citation needed ]}

<span class="mw-page-title-main">Piperacillin</span> Chemical compound

Piperacillin is a broad-spectrum β-lactam antibiotic of the ureidopenicillin class. The chemical structure of piperacillin and other ureidopenicillins incorporates a polar side chain that enhances penetration into Gram-negative bacteria and reduces susceptibility to cleavage by Gram-negative beta lactamase enzymes. These properties confer activity against the important hospital pathogen Pseudomonas aeruginosa. Thus piperacillin is sometimes referred to as an "anti-pseudomonal penicillin".

Tigecycline, sold under the brand name Tygacil, is a tetracycline antibiotic medication for a number of bacterial infections. It is a glycylcycline administered intravenously. It was developed in response to the growing rate of antibiotic resistant bacteria such as Staphylococcus aureus, Acinetobacter baumannii, and E. coli. As a tetracycline derivative antibiotic, its structural modifications has expanded its therapeutic activity to include Gram-positive and Gram-negative organisms, including those of multi-drug resistance.

Carbapenems are a class of very effective antibiotic agents most commonly used for the treatment of severe bacterial infections. This class of antibiotics is usually reserved for known or suspected multidrug-resistant (MDR) bacterial infections. Similar to penicillins and cephalosporins, carbapenems are members of the beta-lactam antibiotics drug class, which kill bacteria by binding to penicillin-binding proteins, thus inhibiting bacterial cell wall synthesis. However, these agents individually exhibit a broader spectrum of activity compared to most cephalosporins and penicillins. Furthermore, carbapenems are typically unaffected by emerging antibiotic resistance, even to other beta-lactams.
