AMOXICILLIN AND CLAVULANATE POTASSIUM vs PENICILLIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Amoxicillin inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins. Clavulanate potassium is a beta-lactamase inhibitor that irreversibly inactivates beta-lactamase enzymes, preventing degradation of amoxicillin.
Inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidation and autolysin activation, leading to cell lysis.
500 mg amoxicillin/125 mg clavulanate orally every 8 hours or 875 mg amoxicillin/125 mg clavulanate orally every 12 hours. For severe infections: 875 mg amoxicillin/125 mg clavulanate orally every 8 hours or 1000 mg amoxicillin/62.5 mg clavulanate extended-release orally every 12 hours.
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.

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
moderateAmoxicillin: ~1-1.5 hours; Clavulanate: ~1 hour. Prolonged in renal impairment.
0.5-1.0 hours in normal renal function; prolonged to 7-10 hours in anuria. Dose adjustment required in renal impairment.
Renal: ~50-70% amoxicillin unchanged; ~25-40% clavulanate as metabolites. Fecal: minimal. Biliary: minor.
Primarily renal (60-80% unchanged via glomerular filtration and tubular secretion); biliary/fecal excretion accounts for 10-20%.
