AMPICILLIN TRIHYDRATE vs PENTIDS '400'
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 activity.
Penicillin G binds to penicillin-binding proteins (PBPs) located on the bacterial cell wall, inhibiting transpeptidase activity and disrupting peptidoglycan cross-linking, leading to cell lysis.
250-500 mg PO q6h or 1-2 g IV/IM q4-6h; up to 12 g/day IV for severe infections.
400 mg orally every 6 hours.

Terminal elimination half-life 1-1.8 hours; prolonged in renal impairment (up to 10-20 hours in anuria)
0.5-1 hour in patients with normal renal function. Prolonged to 2-5 hours in renal impairment, requiring dose adjustment.
Renal: 75-90% unchanged; biliary: small amount; fecal: negligible
Primarily renal (tubular secretion and glomerular filtration); 60-90% of dose excreted unchanged in urine within 24 hours. Minor biliary excretion (<10%) and fecal elimination.
