Information

Azithromycin is a macrolide antibiotic used for the treatment of various bacterial infections, including respiratory tract, skin, ear, and eye infections. For ophthalmic use (ATC code S01AA26), it is primarily used as eye drops for bacterial conjunctivitis. Azithromycin is approved for medical use and routinely prescribed in clinical practice.

Pharmacokinetics

Ophthalmic administration, healthy adults, pharmacokinetic parameters estimated from available publications focused mainly on systemic use; direct ophthalmic PK parameters are limited.
