Definitions
- composition containing ambroxol and erdosteine or acetylcysteine and application thereof
- the invention relates to a pharmaceutical composition and an application thereof.
- the pharmaceutical composition contains ambroxol and erdosteine or a pharmaceutically acceptable salt thereof.
- the pharmaceutical composition may further include ambroxol and Application of acetylcysteine or a pharmaceutically acceptable salt of the two, and the combination of such drugs for the preparation of drugs for the prevention and treatment of various diseases such as respiratory congestion and infection, inflammation and expectoration, especially for expectoration . Background technique
- Ambroxol is the active metabolite of bromhexine. It has low toxicity and accurate curative effect. Its expectorant effect is stronger than that of bromhexine. In 1984, the drug was used as a hydrochloride in the clinic. Ambroxol hydrochloride has been widely used in many countries such as the United States, Britain, Germany, Japan and other countries for the treatment of respiratory diseases with excellent clinical effects and almost no toxic side effects. Ambroxol hydrochloride is widely used clinically for acute and chronic respiratory diseases with abnormal sputum secretion and poor sputum excretion, such as acute and chronic bronchitis, asthma-type bronchitis, bronchiectasis and tracheal asthma, and lung surgery. Preventive and adjuvant treatment of complications of posterior lung symphony, sticky sputum caused by lung structure, difficulty in expectoration, and treatment of respiratory distress syndrome (IRDS) in premature and newborn infants.
- IRDS respiratory distress syndrome
- Ambroxol hydrochloride is quickly absorbed orally and its elimination half-life is 2 to 3 hours. Its main preparations are tablets, sustained-release pellets, solutions, syrups, water injections and other compound preparations. However, due to the water solubility of ambroxol hydrochloride, It is not ideal, and its application and clinical application are limited.
- Erdosteine is a prodrug with a non-free blocked thiol group in its structure and has no active effect on local mucin. After oral administration, three metabolites containing free thiol groups are metabolized to exert pharmacological effects. No obvious gastrointestinal side effects after oral administration. Experiments prove that Erdosteine metabolites can break the disulfide bonds of mucin in bronchial secretions, and change the composition and rheological properties of secretions, reduce the viscosity of sputum and improve the inhibited respiratory function. This product can remove free radicals, Effectively protect al-antitrypsin from smoke and dust-induced oxidative inactivation and prevent damage to lung elastin and neutrophils.
- This product can also significantly increase the ratio of IgA / albumin, lactoferrin / albumin, reduce local inflammation, increase and improve the penetration of antibiotics into the bronchial mucosa, and is beneficial to the treatment of various inflammations of the respiratory tract.
- Acetylcysteine is the most commonly used phlegm-soluble sputum expectorant. It is mainly used for spray inhalation.
