E-MYCIN vs ERYTHRO-STATIN
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.
Erythro-statin is a combination of erythromycin, a macrolide antibiotic that inhibits bacterial protein synthesis by binding to the 50S ribosomal subunit, and a statin (HMG-CoA reductase inhibitor) that inhibits cholesterol synthesis. Synergistic effects on inflammation and atherosclerosis are hypothesized.
250-500 mg orally every 6 hours or 500 mg every 12 hours; maximum 4 g/day.
200 mg intravenously once daily.

1.5-2 hours in adults with normal renal function; prolonged to 4-6 hours in severe hepatic impairment; no significant change in renal impairment due to minimal renal clearance.
2.0-3.5 hours in adults with normal renal function. Extended to 5-8 hours in patients with severe renal impairment (CrCl <30 mL/min).
Primarily hepatic metabolism and biliary excretion with significant enterohepatic circulation; approximately 2-15% excreted unchanged in urine; 10-40% excreted in feces via bile; less than 1% eliminated as unchanged drug in feces from unabsorbed drug.
Approximately 70-80% of the dose is excreted unchanged in urine via glomerular filtration and tubular secretion. About 20-30% is eliminated unchanged in feces via biliary secretion.
