DYNAPEN vs PENICILLIN G POTASSIUM IN PLASTIC CONTAINER
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), 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.
2-4 million units IV every 4 hours for moderate to severe infections; up to 24 million units/day for serious infections (meningitis, endocarditis).
