DYNAPEN vs PENTIDS '200'
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dynapen (dicloxacillin) is a penicillinase-resistant penicillin that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to cell lysis and death.
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 for skin and soft tissue infections; up to 500 mg every 6 hours for respiratory tract infections.
Penicillin G benzathine: 1.2 million units intramuscularly as a single dose.
