ERYTHRO-STATIN vs ERYTHROMYCIN ETHYLSUCCINATE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Erythromycin ethylsuccinate is a macrolide antibiotic that binds to the 50S subunit of the bacterial ribosome, inhibiting protein synthesis by blocking translocation of peptidyl-tRNA. It may also have anti-inflammatory and immunomodulatory effects.
200 mg intravenously once daily.
400-800 mg orally every 6 hours or 4 times daily; maximum 4 g/day. Intravenous form available but ethylester is oral only.

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).
Terminal elimination half-life: 1.5-2 hours in adults with normal renal function; extended to 5-6 hours in patients with severe hepatic impairment; not significantly altered by renal failure.
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.
Primarily hepatic metabolism and biliary excretion (80-90% as unchanged drug and metabolites into bile); renal excretion accounts for 5-15% of unchanged drug; fecal elimination of unabsorbed drug.
