AMPICILLIN TRIHYDRATE vs PENTIDS '250'
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 cell wall synthesis, leading to bacterial lysis.
250-500 mg PO q6h or 1-2 g IV/IM q4-6h; up to 12 g/day IV for severe infections.
250 mg orally every 8 hours.
