ERYGEL vs TAO
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Erythromycin is a macrolide antibiotic that inhibits bacterial protein synthesis by binding to the 50S ribosomal subunit, blocking the translocation of peptidyl-tRNA.
Troleandomycin (TAO) is a macrolide antibiotic that inhibits bacterial protein synthesis by binding to the 50S ribosomal subunit, preventing peptide chain elongation.
Apply a thin layer to affected areas twice daily. Topical use only.
250-500 mg orally every 6 hours or 500 mg intravenously every 6 hours. For severe infections, up to 500 mg every 6 hours IV.

Terminal elimination half-life is approximately 1.6 hours (range 1.0–2.5 hours) after topical application, too short to accumulate with daily use.
Terminal elimination half-life of 12-24 hours in adults; may be prolonged in hepatic impairment (up to 40-60 hours) and in neonates (2-5 days).
Primarily hepatic metabolism; less than 10% excreted renally as unchanged drug. Biliary excretion is minimal.
Primarily hepatic metabolism with <10% excreted unchanged in urine; approximately 30% excreted in feces via bile.
