Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Erythromycin binds to the 50S ribosomal subunit of susceptible bacteria, inhibiting protein synthesis by blocking the translocation of peptidyl-tRNA. It may also act as a motilin receptor agonist, enhancing gastrointestinal motility.
R-P MYCIN is a macrolide antibiotic that inhibits bacterial protein synthesis by binding to the 50S subunit of the bacterial ribosome, specifically at the 23S rRNA of the peptidyl transferase center. This action blocks the translocation step, thereby preventing the elongation of the peptide chain.
250-500 mg orally every 6 hours (or 333 mg every 8 hours) for adults; maximum 4 g/day.
Rifampin 600 mg orally once daily or 10 mg/kg intravenously once daily.

1.5-2.0 hours in adults with normal renal function; prolonged in neonates (2-4 hours) and patients with hepatic impairment.
Terminal half-life 2-3 hours; prolonged in renal impairment (up to 6-8 hours in anuria).
Primarily biliary (fecal) elimination (60-80% as unchanged drug) with approximately 5-15% renal excretion of active drug.
Renal (60-80% unchanged), biliary/fecal (15-20%).
