Carbenicillin-disodium 1 g
Carbenicillin-disodium 1 g Uses, Dosage, Side Effects, Food Interaction and all others data.
Broad-spectrum semisynthetic penicillin derivative used parenterally. It is susceptible to gastric juice and penicillinase and may damage platelet function.
Carbenicillin-disodium 1 g 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).

How Carbenicillin-disodium 1 g works
Free carbenicillin is the predominant pharmacologically active fraction of the salt. Carbenicillin-disodium 1 g exerts its antibacterial activity by interference with final cell wall synthesis of susceptible bacteria. Penicillins acylate the penicillin-sensitive transpeptidase C-terminal domain by opening the lactam ring. This inactivation of the enzyme prevents the formation of a cross-link of two linear peptidoglycan strands, inhibiting the third and last stage of bacterial cell wall synthesis. Cell lysis is then mediated by bacterial cell wall autolytic enzymes such as autolysins; it is possible that carbenicillin interferes with an autolysin inhibitor.
Toxicity
Carbenicillin-disodium 1 g 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.
Food Interaction
- Take on an empty stomach.
[Moderate] ADJUST DOSING INTERVAL: Certain penicillins may exhibit reduced gastrointestinal absorption in the presence of food.
The therapeutic effect of the antimicrobial may be reduced.
MANAGEMENT: The interacting penicillin should be administered one hour before or two hours after meals.
Penicillin V and amoxicillin are not affected by food and may be given without regard to meals.
Carbenicillin-disodium 1 g Hypertension interaction
[Moderate] Each 382 mg tablet of carbenicillin indanyl sodium contains approximately 23 mg (1 mEq) of sodium.
The sodium content should be considered in patients with conditions that may require sodium restriction, such as congestive heart failure, hypertension, and fluid retention.
