BICILLIN vs UNIPEN IN PLASTIC CONTAINER
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.
Inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidase activity and peptidoglycan cross-linking.
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.
250-500 mg intravenously or intramuscularly every 4-6 hours. Maximum dose 12 g per day.

Terminal elimination half-life: 0.5–1 hour (prolonged in renal impairment); clinical context: requires probenecid for extended action
0.5-1 hour (normal renal function); prolonged to 2-5 hours in renal impairment
Primarily renal (60–70% unchanged via glomerular filtration and tubular secretion); minor biliary/fecal elimination (<10%)
Renal: 60-90% unchanged via glomerular filtration and tubular secretion; biliary/fecal: minor, <10%
