Discovered as natural products from actinomycetes soil bacteria, the tetracyclines were first reported in the scientific literature in 1948. They were noted for their broad spectrum antibacterial activity and were commercialized with clinical success beginning in the late 1940s to the early 1950s. By catalytic hydrogenation of Aureomycin, using palladium metal and hydrogen, the C7 deschloro derivative was synthesized, producing a compound of higher potency, a better solubility profile, and favorable pharmacological activity; it was subsequently named tetracycline. Tetracyclines are primarily bacteriostatic and exert their antimicrobial effect by the inhibition of protein synthesis by binding to the 30S ribosomal subunit. Tetracycline is active against a broad range of gram-negative and gram-positive organisms. Tetracycline is indicated in the treatment of infections caused by susceptible strains. To reduce the development of drug-resistant bacteria and maintain the effectiveness of tetracycline hydrochloride and other antibacterial drugs, tetracycline hydrochloride should be used only to treat or prevent infections that are proven or strongly suspected to be caused by bacteria.

Approved Use

Tetracycline is indicated in the treatment of infections caused by susceptible strains of the designated organisms in the conditions listed below: • Upper respiratory tract infections caused by Streptococcus pyogenes, Streptococcus pneumoniae and Hemophilus influenzae. Note: Tetracycline should not be used for streptococcal disease unless the organism has been demonstrated to be susceptible. • Lower respiratory tract infections caused by Streptococcus pyogenes, Streptococcus pneumoniae, Mycoplasma pneumoniae (Eaton agent, and Klebsiella sp.) • Skin and soft tissue infections caused by Streptococcus pyogenes, Staphylococcus aureaus. (Tetracyclines are not the drugs of choice in the treatment of any type of staphylococcal infections.) • Infections caused by rickettsia including Rocky Mountain spotted fever, typhus group infections, Q fever, rickettsialpox. • Psittacosis caused by Chlamydophila psittaci. • Infections caused by Chlamydia trachomatis such as uncomplicated urethral, endocervical or rectal infections, inclusion conjunctivitis, trachoma, and lymphogranuloma venereum. • Granuloma inquinale caused by Klebsiella granulomatis. • Relapsing fever caused by Borrelia sp. • Bartonellosis caused by Bartonella bacilliformis. • Chancroid caused by Hemophilus ducreyi. • Tularemia caused by Francisella tularensis. • Plaque caused by Yersinia pestis. • Cholera caused by Vibrio cholerae. • Brucellosis caused by Brucella species (tetracycline may be used in conjunction with an aminoglycoside). • Infections due to Campylobacter fetus. • As adjunctive therapy in intestinal amebiasis caused by Entamoeba histolytica. • Urinary tract infections caused by susceptible strains of Escherichia coli, Klebsiella, etc. • Other infections caused by susceptible gram-negative organisms such as E. coli, Enterobacter aerogenes, Shigella sp., Acinetobacter sp., Klebsiella sp., and Bacteroides sp. • In severe acne, adjunctive therapy with tetracycline may be useful. When penicillin is contraindicated, tetracyclines are alternative drugs in the treatment of the following infections: • Syphilis and yaws caused by Treponema pallidum and pertenue, respectively, • Vincent’s infection caused by Fusobacterium fusiforme, • Infections caused by Neisseria gonorrhoeae, • Anthrax caused by Bacillus anthracis, • Infections due to Listeria monocytogenes, • Actinomycosis caused by Actinomyces species, • Infections due to Clostridium species.

Sample Use Guides

TETRACYCLINE HYDROCHLORIDE - tetracycline hydrochloride capsule Adults: Usual daily dose, 1 gram as 500 mg twice a day or 250 mg four times a day. Higher doses such as 500 mg four times a day may be required for severe infections or for those infections which do not respond to the smaller doses. For pediatric patients above eight years of age: Usual daily dose, 10 mg/lb to 20 mg/lb (25mg/kg to 50 mg/kg) body weight divided in four equal doses. TETRACYCLINE VISION 10 mg/g eye ointment Adults and children: depending on the severity of condition, a strip of the eye ointment with length of 1 – 1.5 cm is inserted into the conjunctival fold of the lower eyelid 3 - 4 times daily and in more severe cases, up to 6 times daily.
