Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Erythromycin binds to the 50S ribosomal subunit of susceptible bacteria, inhibiting protein synthesis by blocking the translocation step.
Erythromycin binds to the 50S subunit of the bacterial ribosome, inhibiting protein synthesis by blocking the translocation step. It may also act as a motilin receptor agonist, stimulating gastrointestinal motility.
250-500 mg orally every 6 hours or 333-666 mg every 8 hours. Maximum 4 g/day.
250-500 mg orally every 6 hours for mild to moderate infections; up to 4 g/day for severe infections.

The terminal elimination half-life of erythromycin base is approximately 1.5-2 hours in patients with normal renal function. In patients with end-stage renal disease, the half-life may be prolonged to 4-6 hours. The half-life is not significantly altered in hepatic impairment, but accumulation can occur with severe liver disease.
1.5-2 hours in adults; prolonged to 5-6 hours in severe hepatic impairment. In anuria, half-life not significantly affected.
Erythromycin is primarily excreted in bile as active drug and metabolites, with approximately 12-15% of an administered dose excreted unchanged in urine. Fecal elimination accounts for about 30-60% of the dose, largely due to biliary excretion.
Primarily biliary-fecal (90-95% as unchanged drug and metabolites); renal excretion accounts for 2-15%.
