BRISTAMYCIN vs ERYMAX
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
BRISTAMYCIN is a beta-lactam antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidase activity, and activating autolytic enzymes.
Erythromycin acts by binding to the 50S subunit of the bacterial ribosome, inhibiting protein synthesis. It also acts as a motilin receptor agonist, stimulating gastrointestinal motility.
500 mg intravenously every 6 hours. Infuse over 60 minutes.
250-500 mg orally every 6 hours or 500-1000 mg intravenously every 6 hours.

Terminal elimination half-life: 6–8 hours (prolonged to 20–40 hours in severe renal impairment; dose adjustment required for CrCl <30 mL/min).
Terminal elimination half-life: 1.5–2 hours in adults; prolonged to 4–6 hours in hepatic impairment; requires dosing adjustment in cirrhosis.
Renal: 80–90% unchanged via glomerular filtration and tubular secretion; biliary/fecal: <5% as unchanged drug and metabolites.
Renal excretion of unchanged drug: 10–15%; biliary/fecal excretion: 85–90% as active metabolites.
