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 step.
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 333-666 mg every 8 hours. Maximum 4 g/day.
200 mg intravenously once daily.

The terminal elimination half-life of erythromycin base is approximately 1.5-2 hours in patients with normal renal function. In patients with end-stage renal disease, the half-life may be prolonged to 4-6 hours. The half-life is not significantly altered in hepatic impairment, but accumulation can occur with severe liver disease.
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).
Erythromycin is primarily excreted in bile as active drug and metabolites, with approximately 12-15% of an administered dose excreted unchanged in urine. Fecal elimination accounts for about 30-60% of the dose, largely due to biliary excretion.
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.
