Abstract

The present invention relates to a method for improving the stability of ambroxol hydrochloride. The main component ambroxol hydrochloride is slightly soluble and unstable, and can be effectively solubilized using glycerin and propylene glycol. The glycerin formula and preparation method have good effects on the stability of the main drug. Stability has a greater impact, and the product obtained by the propylene glycol formula has good stability. Accelerated stability and long-term stability tests have proven that this formula and preparation method have better stability than the same product on the market. stability.

Description

technical field [0001] The invention relates to a preparation method of ambroxol hydrochloride. Background technique [0002] Ambroxol hydrochloride (ambroxol hydrochloride), also known as bromcycline hydrochloride, is a new generation of mucus-dissolving agent, which can promote the emptying of bronchial cilia and facilitate the discharge of airway secretions. It is mainly used clinically for acute and chronic respiratory diseases , especially in the expectorant treatment of chronic bronchitis. Existing ambroxol hydrochloride has poor stability in related dosage forms with water as solution. Contents of the invention [0003] The purpose of the present invention is to overcome the defect of ambroxol hydrochloride solubility in water and provide a kind of formula and preparation method that can improve the stability of ambroxol hydrochloride. [0004] The specific technical scheme of the present invention uses propylene glycol as an auxiliary material to greatly improve ...
