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.

Tetracycline is often an alternative drug for people who are allergic to penicillin.
Tetracyn
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.
Tetracyn
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.
