Etanercept, also known as amiloride oral solution, the main active ingredients are amiloride and clenbuterol, which are not antibiotics. Ambroxol is a sputum solubilizer, which can increase the secretion of plasma glands of respiratory mucosa and decrease the secretion of mucus glands, thus reducing the viscosity of sputum, which can promote the secretion of lung surface active substances and increase the movement of bronchial cilia, so that sputum can be coughed out easily. Clenbuterol hydrochloride is a selective beta agonist, which has the effect of relaxing bronchial smooth muscle, increasing cilia movement, dissolving sputum and promoting sputum expulsion, so both of these two main ingredients are not antibiotics. In clinical practice, this drug can be mainly used for the treatment of acute and chronic respiratory diseases, such as acute and chronic bronchitis, bronchial asthma, emphysema and other symptoms caused by cough, sputum thickening, difficult sputum expulsion, wheezing, etc. In a word, Etanercept is a compound preparation composed of amiloride and clenbuterol, which does not contain antibiotics.
