Chlortetracycline is a broad-spectrum tetracycline antibiotic, formerly used for treating bacterial infections in humans and animals, especially for eye infections (ophthalmic use). Due to resistance and adverse effects, its systemic human use is now rare and it is primarily used topically or in veterinary medicine. It is not currently a first-line approved drug for systemic human use.
Pharmacokinetics
No peer-reviewed human pharmacokinetic study available for chlortetracycline; pharmacokinetic parameters are estimated based on similarities with other tetracyclines and limited historical reports.
