Medication guide:

Tetracycline is an antibiotic officially included in the World Health Organization Model List of Essential Medicines. The discovery of Tetracycline has boosted the creation of other antibiotics by altering the initial formula. Therefore, its discovery is considered the most significant in the history of antibiotics research and creation.

The medicine is a polyketide antibiotic found first as a natural product in 1945 and first appointed for the treatment of infection in 1948. It is effective in treatment of multiple bacterial infections. Therefore, it is considered a broad-spectrum antibiotic. It is produced by the Streptomyces genus of Actinobacteria, a type of Gram-positive bacteria with the high percentage of nitrogenous bases in the bacteria DNA.

Tetracycline is marketed in all countries. However, the names of the medicine vary:  in the United States the medicine is sold as Emtet-500, Sumycin, Achromycin V, Panmycin. In other countries, for example, in Russia, it is called Tetracycline, in Canada – Achrocidin, Achromycin, and others. In Malaysia – Dhatracin, in Spain – Hortetracin. There are hundreds of names for Tetracycline. Some of them even remotely do not resemble the main substance name. In the internet, at online pharmacies, you can find these medicines searching for Generic Tetracycline. At online pharmacies, the medicine is available without a prescription while in the USA its legal status obliges pharmacies to release it only with a prescription.

Chemical properties of Tetracycline

The formula of the medicine is C22H24N2O8. Tetracycline is available as a yellow crystalline powder for the preparation of oral suspension. The same powder can be found in capsules of the drug. The name of the active substance is Tetracycline hydrochloride.

Mechanism of Tetracycline action

Tetracycline is a protein synthesis inhibitor. It prevents the charged aminoacyl-tRNA connection with the A site on the ribosome. Doing so, it keeps off new amino acids from the new peptide chains, so they cannot develop properly. The medicine does not affect the same processes in human cells and, therefore, is considered safe.

Pharmacokinetics of Tetracycline

Tetracycline is well but not completely absorbed from the gastrointestinal tract. Only around 65% of Tetracycline can be found in blood plasma after two-four hours of the medicine oral intake. Nevertheless, the transportation of Tetracycline in all tissues and fluids of the body is impeccable. After the intake, the medicine is transported to lungs, kidney, prostate, liver, brain, and bones. It can be found in synovial fluid, cerebrospinal fluid, mucosa of the maxillary sinus, bile, and sputum. The medicine is excreted in feces and primarily in urine. Therefore, the use of Tetracycline requires fully functioning and healthy kidneys.

Tetracycline supply form

The medicine can be purchased in form of 250 mg or 500 mg tablets or capsules and crystalline powder for oral suspension (syrup) preparation of 125 mg per 5 milliliters.

Tetracycline or the medicines based on the same active substance are used to treat a vast variety of infections and diseases caused by bacteria sensible to the drug components, such as urogenital system diseases including syphilis, gonorrhea, upper and lower airway diseases including pneumonia, tonsillitis, laryngitis, sinusitis, soft tissue infections including plague, conjunctivitis, typhus, Rocky Mountain spotted fever, intestinal amebiasis, brucellosis, rosacea, rickettsial pox, psittacosis, and yaws.

Tetracycline is also effective in some types of acne. The group of Tetracycline antibiotics is effective against almost all Gram-positive and Gram-negative bacteria. Currently, it is considered that the medicine is mostly effective against Chlamydia, Mycoplasma and Rickettsia phatogens and less effective against Proteus spp. and Pseudomonas aeruginosa, which show inherent resistance. Acquired resistance had also spread among various types of bacteria resulting in lesser efficiency of the medicine in the treatment of diseases caused by certain pathogens. Therefore, an effective treatment requires prior susceptibility tests in order for medics to determine whether Tetracycline will be suitable for a certain condition or a patient.

Besides the treatment of infections, Tetracycline is used to identify the bone growth when biopsy is appointed.
