Broad-spectrum semisynthetic penicillin derivative used parenterally. It is susceptible to gastric juice and penicillinase and may damage platelet function. [PubChem]
Indication
For the treatment of acute and chronic infections of the upper and lower urinary tract and in asymptomatic bacteriuria due to susceptible strains of bacteria.
Pharmacology
Carbenicillin is a semisynthetic penicillin. Though carbenicillin provides substantial in vitro activity against a variety of both gram-positive and gram-negative microorganisms, the most important aspect of its profile is in its antipseudomonal and antiproteal activity. Because of the high urine levels obtained following administration, carbenicillin has demonstrated clinical efficacy in urinary infections due to susceptible strains of: Escherichia coli, Proteus mirabilis, Proteus vulgaris, Morganella morganii, Pseudomonas species, Providencia rettgeri, Enterobacter species, and Enterococci (S. faecalis).
Toxicity
Carbenicillin blood levels achievable are very low, and toxic reactions as a function of overdosage should not occur systematically. The oral LD50 in mice is 3,600 mg/kg, in rats 2,000 mg/kg, and in dogs is in excess of 500 mg/kg. The lethal human dose is not known. Symptoms of overdose include diarrhea, nausea, stomach upset, and vomiting.
Affected Organisms
Enteric bacteria and other eubacteria
Biotransformation
Minimal.
Absorption
Rapidly absorbed from the small intestine following oral administration. Oral bioavailability is 30 to 40%.
Application Used for selection of ampr transformed cells. Use to study the role of penicillin-sensitive transpeptidases in cell wall biosynthesis. Biochem/physiol Actions 羧苄青霉素是氨苄青霉素的类似物,是一种常用的选择剂,它可以结合并抑制细菌细胞壁合成中涉及到的酶。它对耐氨苄青霉素的大多数铜绿假单胞菌分离株以及某些吲哚阳性变形杆菌?均有效。氨苄青霉素及其类似物抗性基因 ampr 编码 β-内酰胺酶。羧苄青霉素比氨苄青霉素对 β-内酰胺酶的敏感性更弱。此外它在低 pH 下具有优异的稳定性。实验表明,用羧苄青霉素替代氨苄青霉素有助于防止卫星菌落的过度生长。有效浓度:50 至 100μg/mL。 Protocols & Applications Antibiotic Selector for application, solubility, solution stability, working concentration, and mode of action information
