ERYTHRO-STATIN vs PEDIAMYCIN
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 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 be bacteriostatic or bactericidal depending on concentration and organism.
200 mg intravenously once daily.
250-500 mg orally every 6 hours; maximum 2 g/day.

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).
The terminal elimination half-life is approximately 1.5-2 hours in adults with normal renal function. In patients with severe hepatic impairment, half-life may be prolonged to 5-6 hours. The short half-life necessitates frequent dosing (every 6-8 hours) to maintain therapeutic levels.
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.
PEDIAMYCIN (erythromycin ethylsuccinate) is primarily excreted via the biliary route (60-70% as unchanged drug and metabolites) with significant fecal elimination. Renal excretion accounts for only 5-15% of the dose, mostly as inactive metabolites. Less than 5% is excreted unchanged in urine.
