Indication
Used to treat bacterial infections such as Rocky Mountain spotted fever, typhus fever, and tick fevers; upper respiratory infections; pneumonia; gonorrhea; amoebic infections; and urinary tract infections. It is also used to help treat severe acne and to treat trachoma (a chronic eye infection) and conjunctivitis (pinkeye). Tetracycline is often an alternative drug for people who are allergic to penicillin.
Polycycline
Pharmacology
Tetracycline is a short-acting antibiotic semisynthetically produced from chlortetracycline, which is derived from Streptomyces aureofaciens. Tetracycline inhibits cell growth by inhibiting translation. It binds to the 30S ribosomal subunit and prevents the amino-acyl tRNA from binding to the A site of the ribosome. This binding is reversible in nature.
Polycycline
Absorption
Bioavailability is less than 40% when administered via intramuscular injection, 100% intravenously, and 60-80% orally (fasting adults). Food and/or milk reduce GI absorption of oral preparations of tetracycline by 50% or more.
