BRISTAMYCIN vs ERYTHROMYCIN
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.
Binds to the 50S ribosomal subunit, inhibiting bacterial protein synthesis by blocking the translocation step.
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; maximum 4 g/day.

Terminal elimination half-life: 6–8 hours (prolonged to 20–40 hours in severe renal impairment; dose adjustment required for CrCl <30 mL/min).
Clinical Note
moderateErythromycin + Norfloxacin
"Erythromycin may increase the QTc-prolonging activities of Norfloxacin."
Clinical Note
moderateErythromycin + Teriflunomide
"The serum concentration of Teriflunomide can be increased when it is combined with Erythromycin."
Clinical Note
moderateErythromycin + Ibandronate
"Erythromycin may increase the QTc-prolonging activities of Ibandronate."
Clinical Note
moderateErythromycin + Indapamide
Terminal half-life is 1.4-2 hours in adults with normal renal function; may be prolonged to 5-6 hours in anuria.
Renal: 80–90% unchanged via glomerular filtration and tubular secretion; biliary/fecal: <5% as unchanged drug and metabolites.
Primarily hepatic (biliary) elimination; approximately 2-5% excreted unchanged in urine, 30-60% excreted in feces via bile.
