AMOXICILLIN vs PENBRITIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Amoxicillin is a beta-lactam antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidase activity, and activating autolytic enzymes.
Penicillin G inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidase activity and preventing peptidoglycan cross-linking, leading to cell lysis.
250-500 mg orally every 8 hours or 500-875 mg orally every 12 hours; for severe infections, up to 1 g orally every 8 hours.
250-500 mg orally every 6 hours; 500 mg to 2 g intramuscularly or intravenously every 4-6 hours.

Clinical Note
moderateAmoxicillin + Acemetacin
"Amoxicillin may decrease the excretion rate of Acemetacin which could result in a higher serum level."
Clinical Note
moderateAmoxicillin + Probenecid
"The serum concentration of Probenecid can be increased when it is combined with Amoxicillin."
Clinical Note
moderateAmoxicillin + Fluconazole
"The metabolism of Fluconazole can be decreased when combined with Amoxicillin."
Clinical Note
moderateAmoxicillin + Clotrimazole
Terminal elimination half-life: 1-1.5 hours in normal renal function. Prolonged to 7-20 hours in end-stage renal disease.
0.5-1 hour in normal renal function; extended to 2-6 hours in renal impairment. Hemodialysis shortens half-life.
Renal: 60-80% unchanged via glomerular filtration and tubular secretion. Biliary: up to 20% excreted in bile. Fecal: minimal.
Renal: ~75-90% unchanged via glomerular filtration and tubular secretion. Biliary: ~10% in feces. Minor hepatic metabolism to penicilloic acid.
