Tetracycline antibiotics - Wikipedia. This article is about the group of antibiotics known as the tetracyclines. For the specific antibiotic called "tetracycline", see tetracycline.
Skeletal formula of tetracycline with atoms and four rings numbered and labeled. Tetracyclines are broad- spectrum antibiotics whose general usefulness has been reduced with the onset of antibiotic resistance. Despite this, they remain the treatment of choice for some specific indications. They are so named for their four ("tetra- ") hydrocarbon rings ("- cycl- ") derivation ("- ine"). To be specific, they are defined as "a subclass of polyketides having an octahydrotetracene- 2- carboxamide skeleton". They are collectively known as "derivatives of polycyclic naphthacene carboxamide". Medical usesTetracyclines are generally used in the treatment of infections of the urinary tract, respiratory tract, and the intestines and are also used in the treatment of chlamydia, especially in patients allergic to β- lactams and macrolides; however, their use for these indications is less popular than it once was due to widespread development of resistance in the causative organisms.Their most common current use is in the treatment of moderately severe acne and rosacea (tetracycline, oxytetracycline, doxycycline or minocycline).Anaerobic bacteria are not as susceptible to tetracyclines as are aerobic bacteria.Doxycycline is also used as a prophylactic treatment for infection by Bacillus anthracis (anthrax) and is effective against Yersinia pestis, the infectious agent of bubonic plague.
It is also used for malaria treatment and prophylaxis, as well as treating elephantitis filariasis.Tetracyclines remain the treatment of choice for infections caused by chlamydia (trachoma, psittacosis, salpingitis, urethritis and L. Rickettsia (typhus, Rocky Mountain spotted fever), brucellosis and spirochetal infections (borreliosis, syphilis and Lyme disease). In addition, they may be used to treat anthrax, plague, tularemia and Legionnaires' disease. They are also used in veterinary medicine.They may have a role in reducing the duration and severity of cholera, although drug- resistance is mounting and their effect on overall mortality is questioned.Tetracycline derivatives are currently being investigated for the treatment of certain inflammatory disorders.Side- effects from tetracyclines are not common, but of particular note is phototoxicity. It increases the risk of sunburn under exposure to light from the sun or other sources. Enable Netmeeting In Xp. Things To Do In Houston Texas For Young Adults.

Tetracyclines are teratogens due to the likelihood of causing teeth discolouration in the fetus as they develop in infancy. For this same reason, tetracyclines are contraindicated for use in children under 8 years of age. Some adults also experience teeth discoloration (mild grey hue) after use.
They are, however, safe to use in the first 1. Some patients taking tetracyclines require medical supervision because they can cause steatosis and liver toxicity.[1. CautionsTetracyclines should be used with caution in those with liver impairment and those that are soluble in water and urine worsen renal failure (this is not true of the lipid- soluble agents doxycycline and minocycline). They may increase muscle weakness in myasthenia gravis and exacerbate systemic lupus erythematosus. Antacids containing aluminium and calcium reduce the absorption of all tetracyclines, and dairy products reduce absorption greatly for all but minocycline.
The breakdown products of tetracyclines are toxic and can cause Fanconi syndrome, a potentially fatal disease affecting proximal tubular function in the nephrons of the kidney. Prescriptions of these drugs should be discarded once expired because they can cause hepatotoxicity. It was once believed that tetracycline antibiotics impair the effectiveness of many types of hormonal contraception. Recent research has shown no significant loss of effectiveness in oral contraceptives while using most tetracyclines.
