BICILLIN C-R vs DISPERMOX
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Benzathine penicillin G and procaine penicillin G are beta-lactam antibiotics that inhibit bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidase activity, and activating autolytic enzymes, leading to cell lysis.
Amoxicillin inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidase activity and disrupting peptidoglycan cross-linking.
1.2 million units intramuscularly as a single dose (600,000 units procaine penicillin G and 600,000 units benzathine penicillin G) for moderate to severe infections; for mild infections, 600,000 units intramuscularly as a single dose.
Adults: 1 g (as amoxicillin 875 mg + clavulanate 125 mg) orally every 12 hours for 7-10 days.

Penicillin G: 0.5-1 hour in normal renal function; prolonged to 7-10 hours in anuria. Benzathine component sustains low levels for days; effective half-life of benzathine penicillin G is 3-5 days due to slow release.
Terminal elimination half-life 1.5 hours; prolonged in renal impairment.
Renal excretion primarily via glomerular filtration and tubular secretion; approximately 60-70% of penicillin G is excreted unchanged in urine within 6 hours; benzathine and procaine components are metabolized and excreted renally as well; small amounts in bile and feces.
Renal excretion 80% as unchanged drug, biliary/fecal 10%.
