PENBRITIN-S vs PENTIDS '800'
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Penicillinase-sensitive penicillin; inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidase activity, and activating autolytic enzymes.
Penicillin G is a beta-lactam antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), transpeptidases that catalyze the final transpeptidation step of peptidoglycan cross-linking, leading to cell lysis.
250-500 mg orally every 6 hours or 500 mg-1 g intramuscularly/intravenously every 4-6 hours for moderate to severe infections.
800 mg orally every 6 to 8 hours; maximum 4 g per day.
