    Trivia questions: What is tetracycline?

    Tetracycline definition

    Tetracycline is the most basic compound in the tetracycline family of antibiotics. Both itself and its salts are yellow or light yellow crystals, which are extremely stable in a dry state. Except for chlortetracycline, other aqueous solutions of the tetracycline family are quite stable.

    Is tetracycline an antibiotic?

    Tetracycline antibiotics

    Tetracycline antibiotics are a broad-spectrum antibiotic with a phenanthrene nucleus found in the 1940s. This class of antibiotics is widely used for infections caused by Gram-positive and negative bacteria, intracellular mycoplasma, chlamydia, and rickettsial.

    Tetracycline class

    Tetracyclines are a broad-spectrum antibiotic produced by actinomycetes, including chlortetracycline, oxytetracycline, tetracycline, and the semi-synthetic derivative methotomycin. The structure of erythromycin, dimethylaminotetracycline and the like all contain a tetraphenyl main skeleton.

    Tetracycline mechanism of action

    Tetracycline antibiotics form a reversible conjugate with the 30S subunit of the bacterial inner ribosomes, inhibiting protein synthesis and exerting antibacterial effects. When the antibiotic concentration is low, this reversible competitive binding will also lose effect, and the protein synthesis of bacteria will continue. Tetracycline can also inhibit mitochondrial protein synthesis by binding to the mitochondrial 70S subunit. The ability of tetracycline to bind to the ribosomal 80S subunit of eukaryotic cells is relatively weak, so the ability to inhibit protein synthesis in eukaryotic cells is also weak. This may be the reason for the strong antibacterial effect of tetracycline and the small side effects on humans.

    Tetracycline uses

    Tetracycline is used for the diagnosis of malignant tumors, various cysts, treatment of refractory pleural effusion and effusion, treatment of bronchopleural fistula, treatment of underarm odor, treatment of internal hemorrhoids, Tetracycline for acne and so on. Yellowing of teeth can occur in children, and teeth discoloration and bone growth inhibition can occur in pregnant women. Therefore, children and pregnant women are cautious or banned from taking this medicine.

    Tetracycline ointment

    It is mainly used for skin surface infection caused by sensitive Gram-positive bacteria and Gram-negative bacteria. Tetracycline dosage: Oral, commonly used for adults: 0.25-0.5g once, once every 6 hours. Common dosage for children over 8 years: 25-50 mg / kg a day, divided into 4 doses. The course of treatment is generally 7 to 14 days. Mycoplasma pneumonia and brucellosis take about 3 weeks.

    Tetracycline capsules

    Mainly used in the following diseases
    (1) Rickettsia, including epidemic typhus, endemic typhus, Rocky Mountain fever, tsutsugamushi disease, and Q fever.
    (2) Mycoplasma infection.
    (3) Chlamydia infections, including parrot fever, sexually transmitted diseases, lymphodontomatosis, non-specific urine

    Tetracycline side effects

    The most common adverse reactions are gastrointestinal symptoms. For example, after using this drug, it can cause nausea and vomiting, uncomfortable stomach, bloating, diarrhea and other conditions. Occasionally some patients can cause problems with esophagitis and pancreatitis.
    The second common side effect can be toxic to the liver. Patients with liver problems are more likely to develop this type of liver toxicity. Patients can develop fatty liver degeneration, which can lead to elevated blood transaminase and bilirubin.
    The third common adverse reaction is an allergic reaction such as rash, urticaria, edema, etc., and some patients can cause anemia, thrombocytopenia, and even neutropenia and eosinophilia.

    Tetracycline allergy

    Mild allergic reactions, skin rashes, edema and urticaria, severe cases will appear panic and chest tightness, anaphylactic shock, causing danger to life.


    Tetracycline is widely used in all walks of life. Tetracycline and milk are a long-standing topic, especially when tetracycline is used as a veterinary antibiotic in dairy farming. Necessary tasks for the farmer. Ballya will provide a rapid test kit for tetracycline for those who need it. The test results comply with EU standards. Not only is the operation simple, but the time is short and the accuracy is high. Not only that, Ballya also provides a variety of fast and effective milk detection kits, and will continue to do more in-depth research in this area.
