Tetracycline is a broad-spectrum antibiotic used to treat a wide array of bacterial infections, including respiratory tract infections, urinary tract infections, and certain sexually transmitted diseases. It works by inhibiting protein synthesis in bacteria. Though widely used in the past, tetracycline use has declined due to bacterial resistance and newer antibiotics. It is still sometimes prescribed today, but more modern tetracyclines are generally preferred.
Pharmacokinetics
Reported population pharmacokinetic parameters in healthy adult volunteers, generally after oral administration.
