Erythromycin is a macrolide antibiotic used primarily for the treatment of respiratory tract infections, skin infections, and some sexually transmitted infections. It is active against many Gram-positive bacteria and some Gram-negative bacteria. Erythromycin is approved and still used clinically, although its use has declined with the introduction of newer macrolides.
Pharmacokinetics
Pharmacokinetic parameters reported in healthy adult volunteers after a single oral dose of erythromycin base.
