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.

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.
