clenbuterol hydrochloride - Reference Information
| Properties | Clenbuterol hydrochloride is a white or almost white crystalline powder; odorless, slightly bitter taste. It is dissolved in water or ethanol, slightly soluble in chloroform or acetone, and insoluble in ether. |
| Pharmacological effects | The chemical structure of clenbuterol hydrochloride is similar to that of adrenergic drugs. It is an adrenergic drug and is a 2-receptor agonist. It has a high selective agonistic effect on the 2-receptors of bronchial, uterine and vascular smooth muscle, and can effectively relieve bronchospasm. In addition, there are strong anti-allergic and significantly enhance the activity of bronchial cilia, and act on the lysosome, which can promote mucus dissolution and facilitate the discharge of sputum. Clinically, it is mainly used for bronchial asthma and wheezing bronchitis. It has a strong and long-lasting effect. It is the main drug to prevent bronchial asthma and bronchospasm. Due to the small amount of this drug (oral dose of 20~40g), and the effect after medication Fast and long maintenance time, so this drug was included in the Second Pharmacopoeia of the People's Republic of China in 2000. Its mechanism of action has been basically clarified. |
| Selective adrenergic β2 receptor agonist | Clenbuterol hydrochloride (clenbuterolhydrochloride), the appearance is a white crystalline powder, the chemical name is hydroxymethyl tert-butinepinephrine or 2-[(tert-butylamino) methyl]-4-amino -3, 5-dichlorobenzene methanol hydrochloride, the drug name is dicloroamine, sulchuanning, quansu, etc. It is a potent selective adrenaline β2 receptor agonist, which can relax bronchial smooth muscle and is used to treat bronchial asthma, asthmatic bronchitis and bronchitis with emphysema. The main ingredient of "Clenbuterol" is clenbuterol hydrochloride. Because it has the effect of promoting protein synthesis in muscle, promoting fat decomposition, and reducing fat accumulation in animals, it can relatively increase the lean meat of animals, thereby improving the quality of animals. It is also called "growth promoter" and "nutritional weight agent". In the early 1960s, it was discovered that it could promote animal growth. In the 1970s, the United States introduced it into livestock and poultry production and became the most widely used β-stimulant in the world. However, because the substance has strong thermal stability and biochemical stability, animals can form accumulative residues in internal organs and tissues after eating it. People who eat pork containing clenbuterol will have symptoms of poisoning. Therefore, countries around the world soon banned the application of β-stimulants in animal husbandry, and many countries have formulated detection methods for monitoring β-stimulant residues and clenbuterol hydrochloride in feed. Our government banned clenbuterol as a feed additive in 1997. Precautions: A small number of patients may have mild palpitations, hand tremors, dizziness and other adverse reactions, continue to take medicine generally can gradually disappear. Use with caution in patients with hyperthyroidism, tachycardia or hypertension. Preparations: Tongtong tablets, aerosols, suppositories, films, patches, etc. (2016-02-01) Figure 1 is the structural formula of clenbuterol hydrochloride |
| use | is used to prevent and treat bronchial asthma, chronic bronchitis and bronchitis with emphysema. It is used to prevent and treat bronchospasm caused by bronchial asthma, chronic bronchitis and bronchitis with emphysema β2-adrenoceptor agonist, bronchodilator. |
