ERYTHRO-STATIN vs ERYTHROMYCIN AND BENZOYL PEROXIDE
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 acts by binding to the 50S ribosomal subunit of susceptible bacteria, inhibiting protein synthesis. Benzoyl peroxide has bactericidal effects against Propionibacterium acnes, likely through the release of free radical oxygen that oxidizes bacterial proteins. It also has keratolytic and comedolytic properties.
200 mg intravenously once daily.
Topical: Apply a thin layer to affected areas once daily in the evening.

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: 1.4–2.0 hours (terminal half-life in adults). Benzoyl peroxide: Not applicable; it is a topical agent with negligible systemic absorption.
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.
Erythromycin is primarily excreted via bile (fecal elimination) with approximately 15% excreted unchanged in urine. Benzoyl peroxide is degraded to benzoic acid, which is conjugated with glycine to form hippuric acid and excreted renally; less than 5% is excreted unchanged in urine.
