BICILLIN vs PENTIDS '200'
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Benzathine penicillin G inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidase activity and autolysin inhibition, leading to cell lysis.
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.
Benzathine penicillin G 1.2 million units intramuscularly once for early syphilis; 2.4 million units intramuscularly weekly for 3 weeks for late latent syphilis.
Penicillin G benzathine: 1.2 million units intramuscularly as a single dose.
