PENBRITIN vs PENTIDS '200'
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Penicillin G is a beta-lactam antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), thereby inhibiting transpeptidation and activating autolytic enzymes.
250-500 mg orally every 6 hours; 500 mg to 2 g intramuscularly or intravenously every 4-6 hours.
Penicillin G benzathine: 1.2 million units intramuscularly as a single dose.

0.5-1 hour in normal renal function; extended to 2-6 hours in renal impairment. Hemodialysis shortens half-life.
0.5-1 hour; prolonged in renal impairment; anuric patients up to 10 hours
Renal: ~75-90% unchanged via glomerular filtration and tubular secretion. Biliary: ~10% in feces. Minor hepatic metabolism to penicilloic acid.
Renal: 60-90% unchanged; biliary/fecal: 10-40%
