    Trivia questions : What is ractopamine, clenbuterol and salbutamol?


    Ractopamine  is a synthetic Clembaam beta adrenal receptor agonist that can be used to treat congestive heart failure, muscular dystrophy, grow muscle, reduce fat accumulation, and benefit the fetus and newborn. Ractopamine is being used by some pig farms as a new type of lean meat extract. The scope of application and safety of this drug in the aquaculture industry varies from country to country. The production and sale of ractopamine has been banned in China since December 5, 2011.

    Ractopamine mechanism of action

    Ractopamine is a synthetic beta-adrenergic agonist (commonly known as beta-stimulant) class of compounds. It is a low-toxic, fast-metabolizing clenbuterol developed by the American pharmaceutical company and belongs to the second generation. Clenbuterol. Because of its role in regulating protein synthesis, it is also known abroad as a protein redistribution agent (Repartitioner). It is mainly used in the treatment of bronchial asthma, congestive heart failure, and muscular dystrophy.

    Ractopamine side effects

    Ractopamine is far less toxic than other lean extracts with the same function. Conventional doses of Clenbuterol can be metabolized and excreted in the body without causing harm to the body. However, excessive intake of ractopamine can cause different degrees of toxic reactions in the human body. The symptoms are similar to those of animal poisoning. Symptoms include muscle tremor, paralysis of the limbs, tachycardia, arrhythmia, abdominal pain, muscle pain, nausea and dizziness. Severe cases can cause hypertension, heart disease and even death.

    Ractopamine hydrochloride

    Ractopamine hydrochloride is a medicinal material, a cardiotonic drug that can be used to treat congestive heart failure. It can also be used to treat muscular dystrophy, grow muscle, reduce fat accumulation, and be beneficial to fetal and newborn growth. The US FDA approved it in 2010 and can be used for animal nutrition re-formulation, and is widely used in animal husbandry and aquaculture. It can simultaneously increase the daily weight gain of animals, increase feed utilization, and increase protein content of animals.


    Clenbuterol is a colorless microcrystalline powder, Chinese alias: Clenbuterol for Clenbuterol; scientific name: Clenbuterol hydrochloride; an asthma drug with molecular formula C12H18Cl2N2O and molecular weight of 277.19, Boiling point is 404.9 ± 40.0 °C (760 mmHg), melting point is 161 °C, soluble in water, ethanol, slightly soluble in acetone, insoluble in ether. This product is an adrenaline bronchial antispasmodic drug. It has good selectivity for the stimulation of bronchial smooth muscle β2 receptors, and the intensity of bronchodilator expansion is 100 times that of Shuchuanning. For the treatment of bronchial asthma, asthmatic bronchitis, etc.

    Clenbuterol mechanism of action

    Clenbuterol is a potent β2 receptor agonist. It is characterized by a small effective dose and long-lasting effect, and its bronchodilator effect is 100 times that of albuterol. Clenbuterol was taken orally 30 μg three times a day in asthma patients, compared with 5 mg orally terbutaline 3 times a day. They have similar effects on increasing FEV1 and maximum expiratory flow rate (FEF) and reducing airway resistance. It can be seen that the asthma effect of oral clenbuterol is 170 times stronger than that of terbutaline.

    Clenbuterol side effects

    Rarely, mild palpitations, finger tremors, dizziness, etc., can usually relieve themselves during medication. In recent years, it has been found that adding clenbuterol to feed can promote animal growth and increase the lean meat ratio of livestock and poultry, so it is called lean meat essence. Poisoning can be caused by consuming the internal organs or meat of animals that contain residual lean meat.

    Clenbuterol hydrochloride

    Clenbuterol hydrochloride, also known as "lean meat powder", is an antiasthmatic drug. Clenbuterol is a β2 receptor agonist, a pseudoadrenergic drug, which is well absorbed in livestock and humans, and has higher bioavailability compared to other β-stimulants. There have been incidents of poisoning of pork containing clenbuterol. Since September 10, 2002, the use of clenbuterol in feed and animal drinking water has been banned in China.


    Salbutamol, a short-acting β2 adrenergic receptor agonist, is used as an asthma drug, which can effectively inhibit the release of allergenic substances such as histamine and prevent bronchospasm. Adding a small amount of salbutamol to livestock feed can increase the lean meat amount, meat exchange rate and reduce fat of livestock, but its toxicity is much higher than that of ractopamine with the same function. For bronchial asthma, asthmatic bronchitis, bronchospasm, emphysema and other symptoms.

    Salbutamol mechanism of action

    It has high selectivity for airway smooth muscle β2 receptors, increased resistance to catechin oxygen methyltransferase and monoamine oxidase, prolonged action time, and has little excitatory effect on the heart. In vitro experiments, the comparison of equal strength concentrations required for airway smooth muscle and myocardial effects, the selectivity index of the drug was obtained, with salbutamol as high as 250, terbutaline as 138, and isoproterenol and adrenaline as 1.4. According to patient observation, comparing the changes in forced expiratory volume (FEV1) and heart rate with intravenous albuterol and isoproterenol for 1 second, a small dose of albuterol at 0.1 μg / kg can increase FEV1 significantly. Fang accelerates heart rate, showing higher selectivity, and isoproterenol can increase heart rate when FEV1 dose is increased, and the selectivity is poor.

    Salbutamol side effects

    The bronchodilator effect of salbutamol is equal to that of isoproterenol, and the effect lasts longer; the effect of increasing heart rate is only 1/10 of isoproterenol. For the treatment of bronchospasm in patients with bronchial asthma, asthmatic bronchitis and emphysema, oral or aerosol inhalation. Oral bioavailability is about 30%, which takes effect for 15 to 30 minutes and lasts for more than 6 hours; bioavailability of aerosol inhalation is about 10%, which takes effect for 1 to 5 minutes, and the maintenance time is 4 to 6 hours.

    Salbutamol sulfate

    Salbutamol sulfate is suitable for bronchial asthma, wheezing bronchitis, and emphysema, etc. It can be used for aerosol inhalation, and can be administered orally to prevent seizures.


    "Clenbuterol" does not refer to a specific drug, but is a generic name for a class of phenethanolamine compounds that promote protein synthesis and inhibit fat deposition. These include ractopamine, clenbuterol and salbutamol. Clenbuterol is banned in many countries because of its harm.
    The ClEN + RAC + ASL Triple Test (Urine) kit provided by BALLYA can effectively detect whether the video contains ractopamine, clenbuterol or salbutamol. This kit is not only simple to operate, but also has a short test time and high accuracy. Can ensure consumers Food safety.
