Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Binds to the 50S ribosomal subunit of susceptible bacteria, inhibiting mRNA translation and thus protein synthesis. Exhibits concentration-dependent bactericidal activity.
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 for 3 days, or 500 mg IV once daily for at least 2 days followed by 500 mg orally to complete 7-10 days of therapy for community-acquired pneumonia. For other indications, typical adult dose is 500 mg orally on day 1 then 250 mg orally once daily on days 2-5.
200 mg intravenously once daily.

Clinical Note
moderateAzithromycin + Norfloxacin
"Azithromycin may increase the QTc-prolonging activities of Norfloxacin."
Clinical Note
moderateAzithromycin + Ibandronate
"Azithromycin may increase the QTc-prolonging activities of Ibandronate."
Clinical Note
moderateAzithromycin + Indapamide
"Azithromycin may increase the QTc-prolonging activities of Indapamide."
Clinical Note
moderateAzithromycin + Artesunate
"The serum concentration of the active metabolites of Artesunate can be reduced when Artesunate is used in combination with Azithromycin resulting in a loss in efficacy."
Terminal half-life of approximately 68 hours (range 35–96 h) after multiple doses, allowing once-daily dosing and a prolonged post-antibiotic effect.
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).
Primarily biliary/fecal (approx. 50% unchanged); renal excretion accounts for about 12% of the dose.
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.
