Ontology: Cefotaxime C Definition NCI A third generation semisynthetic cephalosporin antibiotic with bactericidal activity.Cefpodoxime is an oral, third-generation cephalosporin antibiotic.
It is active against most Gram-positive and Gram-negative organisms. Notable exceptions include Pseudomonas aeruginosaEnterococcusand Bacteroides fragilis. It is commonly used to treat acute otitis mediapharyngitissinusitisand gonorrhea. It also finds use as oral continuation therapy when intravenous cephalosporins such as ceftriaxone are no longer necessary for continued treatment.
Cefpodoxime inhibits cell wall synthesis by inhibiting the final transpeptidation step of peptidoglycan synthesis in cell walls. It is indicated in community acquired pneumonia, uncomplicated skin and skin structure infections, and uncomplicated urinary tract infections. It was patented in and approved for medical use in Cefpodoxime has been used to fight pathogenic bacteria responsible for causing gonorrhoea, tonsillitis, pneumonia, and bronchitis. Representative pathogenic genera include Streptococcus, Haemophilusand Neisseria.

Categories : Cephalosporin antibiotics Thiazoles Ketoximes.Written by C. Fookes, BPharm on Jul 20, Cephalosporins are a large group of antibiotics derived from the mold Acremonium previously called Cephalosporium. Cephalosporins are bactericidal kill bacteria and work in a similar way to penicillins.
They bind to and block the activity of enzymes responsible for making peptidoglycan, an important component of the bacterial cell wall. They are called broad-spectrum antibiotics because they are effective against a wide range of bacteria. Since the first cephalosporin was discovered inscientists have been improving the structure of cephalosporins to make them more effective against a wider range of bacteria. Each time the structure changes, a new "generation" of cephalosporins are made.
So far there are five generations of cephalosporins.
All cephalosporins start with cef, ceph, or kef. Note that this classification system is not used consistently from country to country. Cephalosporins are not usually used as a first-choice antibiotic.
They tend to be reserved for use when other antibiotics often penicillins cannot be used. Within each generation, there are differences in terms of administration such as oral or intravenous administrationabsorption, excretion, and how long the activity of the cephalosporin lasts for in the body. First generation cephalosporins refer to the first group of cephalosporins discovered. Their optimum activity is against gram-positive bacteria such as staphylococci and streptococci. They have little activity against gram-negative bacteria.
There are also differences with regards to how frequently the different first-generation cephalosporins need to be dosed. Second-generation cephalosporins are more active against gram-negative bacteria, with less activity against gram-positive bacteria. Third generation cephalosporins followed the second-generation cephalosporins. No one third-generation cephalosporin treats all infectious disease scenarios. Cefotaxime and ceftizoxime discontinued offer the best gram-positive coverage out of all the third-generation agents; ceftazidime and cefoperazone discontinued are unique in that they provide antipseudomonal coverage.
Ceftriaxone has a long half-life which allows for once daily dosing and may be used for the treatment of gonorrheapelvic inflammatory diseaseand epididymo-orchitis. It is also an alternative to penicillins for suspected meningitis. All the third-generation cephalosporins except for cefoperazone discontinued penetrate cerebrospinal fluid. Fourth generation cephalosporins are structurally related to third-generation cephalosporins but possess an extra ammonium group, which allows them to rapidly penetrate through the outer membrane of gram-negative bacteria, enhancing their activity.
Some fourth-generation cephalosporins have excellent activity against gram-positive bacteria such as methicillin-susceptible staphylococcipenicillin-resistant pneumococciand viridans group streptococci. Cefepime is the only fourth generation cephalosporin available in the United States. Cefpirome is available overseas. Ceftaroline is currently the only next-generation cephalosporin available in the United States. It also retains the activity of the later-generation cephalosporins and is effective against susceptible gram-negative bacteria.
Cephalosporins are generally safe, with low toxicity and good efficacy against susceptible bacteria. Allergic reactions have been reported with cephalosporins and symptoms may include a rash, hives urticariaswelling, or rarely, anaphylaxis. Rarely, seizures have been reported with some cephalosporins; the risk is greatest in those with kidney disease. Cephalosporins have also been associated with a reduced ability of the blood to clot leading to prolonged bleeding times. People with kidney or liver diseasenutritionally deprived, taking cephalosporins long-term, or concurrently receiving anticoagulant therapy are more at risk.
Cephalosporins generally cause few side effects. The most common side effects reported include abdominal pain, diarrheadyspepsiaheadachegastritisand nausea and vomiting. Transient liver problems have also been reported. Rarely, some people may develop a super-infection due to overgrowth of a naturally occurring bacterium called Clostridium difficilefollowing use of any antibiotic, including cephalosporins.The cephalosporins, and the closely related cephamycins, are similar to penicillins in several respects, sharing pharmacologic group features.
The early cephalosporins differed mainly with respect to pharmacokinetic characteristics. Whereas penicillins were classified based on source natural versus semisynthetic and spectra, cephalosporins are classified by generations 1—4. This group includes cephalothin no longer marketed in the USAcephaloridine, cephapirin, cefazolincephalexincephradine, and cefadroxil. Cephalosporins in this group are usually quite active against many gram-positive bacteria but are only moderately active against gram-negative organisms.
They are ineffective against enterococci. Susceptible gram-negative bacteria include Escherichia coli and ProteusKlebsiellaSalmonellaShigellaand Enterobacter spp. Cefazolin is more effective against E coli than cephalexinthe latter of which is minimally susceptible. They are not as effective against anaerobes as are the penicillins. This group includes cefamandole, cefoxitin a cephamycincefotiam, cefachlor, cefuroximeand ceforanide.
These agents are generally active against both gram-positive and gram-negative bacteria. They are ineffective against enterococci, Pseudomonas aeruginosa with the frequent exception of cefoxitinActinobacter spp, and many obligate anaerobes again, cefoxitin is an exception. The third-generation cephalosporins include ceftiofur, ceftriaxonecefsulodin, cefotaximecefoperazone, moxalactam not a true cephalosporinand several others, including cefpodoxime and cefovecin, approved for use in dogs and for use in dogs and cats, respectively.
Cefepime is a fourth-generation cephalosporin. The spectrum of third- and fourth-generation cephalosporins varies and should be confirmed based on culture and susceptibility testing before use. The spectrum of veterinary third-generation cephalosporins should not be considered extended in that efficacy often does not include Pseudomonas or other problematic coliforms.
Ceftiofur has been specifically approved for use in cattle with bronchopneumonia, especially if caused by Mannheimia haemolytica or Pasteurella multocida. Although it is approved for use in dogs to treat urinary tract infections injectableother more convenient drugs are generally used. Cefpodoxime and cefovecin are particularly effective against Staphylococcus pseudintermediuswhile retaining fair efficacy toward gram-negative organisms such as E coliKlebsiellaand Proteus.
Some drugs approved for use in people have only moderate activity against gram-positive bacteria again, enterococci are resistant but have extensive activity against a wide variety of gram-negative bacteria, including Pseudomonas spp, Proteus vulgarisEnterobacter spp, and Citrobacter spp eg, cefotaximeceftazidime. Ceftiofur is a third-generation cephalosporin with a gram-negative spectrum that is more similar to that of first-generation cephalosporins.Third-generation cephalosporins are broad-spectrum antimicrobial agents useful in a variety of clinical situations.
No one cephalosporin is appropriate for all infectious disease problems. Cefotaxime and ceftizoxime have the best gram-positive coverage of the third-generation agents. Ceftazidime and cefoperazone are the only third-generation drugs that provide antipseudomonal coverage. Ceftriaxone's long half-life allows for once-daily dosing, making ceftriaxone an excellent drug for outpatient antibiotic therapy of community-acquired infections.
Ceftriaxone is also useful for the treatment of Lyme disease and sexually transmitted diseases. The third-generation cephalosporins except for cefoperazone penetrate cerebrospinal fluid and are indicated for the treatment of bacterial meningitis.
Their proven record of clinical efficacy, favorable pharmacokinetics, and low frequency of adverse effects make third-generation cephalosporins the preferred antibiotic in many clinical situations. Abstract Third-generation cephalosporins are broad-spectrum antimicrobial agents useful in a variety of clinical situations. Publication types Review.

Table of Contents. Report Description. Research Methodology. Secondary Research. Primary Research. Executive Summary. Key Highlights. Market Overview.Cephalosporins are bactericidal beta-lactam antibiotics.
They inhibit enzymes in the cell wall of susceptible bacteria, disrupting cell synthesis. There are 5 generations of cephalosporins see table Cephalosporins. Cephalosporins penetrate well into most body fluids and the extracellular fluid of most tissues, especially when inflammation which enhances diffusion is present.
However, the only cephalosporins that reach cerebrospinal fluid levels high enough to treat meningitis are. Most cephalosporins are excreted primarily in urine, so their doses must be adjusted in patients with renal insufficiency. Cefoperazone and ceftriaxonewhich have significant biliary excretion, do not require such dose adjustment.
Gram-negative bacteria. Cephalosporins are classified in generations see table Some Clinical Uses of 3rd- and 4th-Generation Cephalosporins. The 1st-generation drugs are effective mainly against gram-positive organisms. Higher generations generally have expanded spectra against aerobic gram-negative bacilli.
The 5th-generation cephalosporins ceftaroline and ceftobiprole are active against methicillin-resistant Staphylococcus aureus. Cephalosporins have the following limitations:. Lack of activity against enterococci.
Lack of activity against methicillin-resistant staphylococci except for ceftaroline and ceftobiprole. Lack of activity against anaerobic gram-negative bacilli except for cefotetan and cefoxitin. Oral 1st-generation cephalosporins are commonly used for uncomplicated skin and soft-tissue infectionswhich are usually due to staphylococci and streptococci.
Parenteral cefazolin is frequently used for endocarditis due to methicillin-sensitive S. Cephamycins are drugs that were originally produced by Streptomyces but are now synthetic. They are typically classed with 2nd-generation cephalosporins. Cephamycins are more active against anaerobes, such as. Bacteroides species, including Bacteroides fragilis. These drugs may be slightly less active against gram-positive cocci than 1st-generation cephalosporins.
