Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dirithromycin is a macrolide antibiotic that binds to the 50S subunit of the bacterial ribosome, specifically to the 23S rRNA, inhibiting peptide chain elongation by blocking the translocation step. It also interferes with the assembly of the 50S ribosomal subunit. This action is primarily bacteriostatic but can be bactericidal at higher concentrations.
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.
500 mg orally once daily or 250 mg orally twice daily; usual duration 5-14 days depending on infection
200 mg intravenously once daily.

Terminal elimination half-life is 9–12 hours in adults with normal renal function; may extend to 20–30 hours in severe renal impairment (CrCl <30 mL/min).
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).
Approximately 65% of a dose is excreted unchanged in the urine via glomerular filtration and tubular secretion; about 15% is excreted unchanged in the bile; fecal elimination accounts for <5%.
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.
