Category C

Head-to-Head

Clinical Matrix

Mechanism of Action

Penicillinase-sensitive penicillin; inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidase activity, and activating autolytic enzymes.

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

Clinical Dosing

250-500 mg orally every 6 hours or 500 mg-1 g intramuscularly/intravenously every 4-6 hours for moderate to severe 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

0.5-1 hour; prolonged in renal impairment (up to 7-10 hours in anuria).

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."
