PENICILLIN vs POLYMOX
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidation and autolysin activation, leading to cell lysis.
Amoxicillin is a bactericidal antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs) and inhibiting transpeptidase activity, leading to cell lysis.
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.
250-500 mg orally every 8 hours or 500-875 mg orally every 12 hours; maximum 4 g/day.

0.5-1.0 hours in normal renal function; prolonged to 7-10 hours in anuria. Dose adjustment required in renal impairment.
Clinical Note
moderateBenzylpenicillin + Teriflunomide
"The serum concentration of Teriflunomide can be increased when it is combined with Benzylpenicillin."
Clinical Note
moderateBenzylpenicillin + Acemetacin
"Benzylpenicillin may decrease the excretion rate of Acemetacin which could result in a higher serum level."
Clinical Note
moderateProcaine benzylpenicillin + Acemetacin
"Procaine benzylpenicillin may decrease the excretion rate of Acemetacin which could result in a higher serum level."
Clinical Note
moderateTerminal elimination half-life = 1-1.5 hours in adults; prolonged in renal impairment (up to 12-20 hours in anuria)
Primarily renal (60-80% unchanged via glomerular filtration and tubular secretion); biliary/fecal excretion accounts for 10-20%.
