| Cefotaxime Usage And Synthesis |
| Description | Like other third-generation cephalosporins, it has excellent anti-Gram-negative activity and is useful institutionally. It has a metabolically vulnerable acetoxy group attached to C-3 and loses approximately 90% of its activity when this is hydrolyzed. This metabolic feature also complicates the pharmacokinetic data, because both active forms are present and have different properties. Cefotaxime should be protected from heat and light and may color slightly without significant loss of potency. Like other third-generation cephalosporins, cefotaxime has less activity against staphylococci but has greater activity against Gram-negative organisms. |
| Originator | Claforan,Hoechst-Roussel,W. Germany,1980 |
| Uses | Cephalosporin antibiotic |
| Uses | Cefotaxime has a broad spectrum of antibicrobial use. It acts bactericidally. It is highly active with respect to Gram-negative microorganisms (E. coli, Citrobacter, Proteus mirabilis, P. indole, Providencia, Klebsiella, Serratia), and a few strains of Pseudomonas, H. influenzae that are resistant to other antibiotics. Cefotaxime is less active with respect to streptococci, pneumococci, meningococci, gonococci, and bacteroides. It is resistant to the majority of beta-lacatamases of Gram-positive and Gram-negative microorganisms. This drug is used for severe bacterial infections caused by microorganisms that are sensitive to the drug such as peritonitis, sepsis, abdominal infections, infections of the pelvis minor, infections of the lower respiratory tract, urinary tract, bones, joints, skin, soft tissues, and infected wounds and burns. Synonyms of this drug are claforan, zarivis, and others. |
| Uses | Cefotaxime is an antibiotic with broad spectrum activity against Gram positive and Gram negative bacteria. |
| Manufacturing Process | A solution of 8 g of sodium bicarbonate in about 20 ml of ethanol was progressively added to 45.55 g of pure 3-acetoxymethyl-7-[2-(2-amino-4- thiazolyl)-2-methoxyiminoacetamido]-ceph-3-eme-4-carboxylic acid in 100 ml of distilled water and another 80 ml of ethanol and 4.5 g of activated carbon were added thereto. The mixture was stirred for 5 minutes and was filtered. The filter was rinsed with ethanol and the filtrate was evaporated to dryness under reduced pressure. The residue was taken up in 100 ml of ethanol and evaporated to dryness again. The residue was dissolved in 100 ml of methanol and the solution was poured into 2 l of acetone. The mixture was vigorously stirred and was vacuum filtered. The recovered product was rinsed with acetone and then ether and dried under reduced pressure to obtain 43.7 g of a white product which rehydrated in air to obtain a final weight of 45.2 g of sodium 3-acetoxymethyl-7-[2-(2-amino-4-thiazolyl)-2- methoxyiminoacetamido]-ceph-3-eme-4-carboxylate. |
