Clinical Matrix

Mechanism of Action

Carbenicillin is a bactericidal penicillin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to cell lysis and death. It has activity against Gram-negative and some Gram-positive bacteria.

Inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidation and autolysin activation, leading to cell lysis.

Clinical Dosing

2 g intravenously every 6 hours for susceptible infections.

Penicillin G: 2-4 million units IV every 4-6 hours; Penicillin V: 250-500 mg orally every 6 hours for mild to moderate infections.

Direct Interaction

None Documented

Half-Life

Terminal half-life 4-6 hours in normal renal function; prolonged to 10-20 hours in moderate renal impairment (CrCl 10-50 mL/min) and up to 30-50 hours in severe impairment (CrCl <10 mL/min).

Other Significant Interactions

Clinical Note

moderate

Benzylpenicillin + Teriflunomide

"The serum concentration of Teriflunomide can be increased when it is combined with Benzylpenicillin."

Clinical Note

moderate

Benzylpenicillin + Acemetacin

"Benzylpenicillin may decrease the excretion rate of Acemetacin which could result in a higher serum level."

Clinical Note

moderate

Procaine benzylpenicillin + Acemetacin

"Procaine benzylpenicillin may decrease the excretion rate of Acemetacin which could result in a higher serum level."
