Problems solved by technology

[0005] The main problem in the preparation process of ambroxol hydrochloride injection is that under oxidative or alkaline conditions, it is easy to dissociate ambroxol, thereby increasing the content of related substances in the storage process and affecting drug efficacy.
In the prior art, it is mainly used to control the lower pH value of the injection and add a stabilizer to improve its stability, but the injection with a low pH value will cause discomfort to the human body during injection, and the patient's compliance is poor

Abstract

The invention discloses an ambroxol hydrochloride injection composition. The ambroxol hydrochloride injection composition contains the following components in parts by weight: 15 parts of ambroxol hydrochloride, 4.5-7.5 parts of vitamin C, 3-5 parts of cysteine, 0.15-0.2 part of EDTA-2Na and a proper amount of an osmotic pressure regulator. The invention further discloses a preparation method of the ambroxol hydrochloride injection composition. The preparation method comprises the steps of adding ambroxol hydrochloride into injection water, heating to 40-50 DEG C until ambroxol hydrochloride is dissolved, adding EDTA-2Na, stirring for dissolving, cooling to 20-30 DEG C, adding cysteine, stirring for dissolving, saturating the solution with carbon dioxide, adding vitamin C, stirring for dissolving, adding the osmotic pressure regulator, regulating the pH value to 5.5-6.0, and carrying out encapsulation and sterilization. The pH value of the ambroxol hydrochloride injection composition is 5.5-6.0, the uncomfortable feel during the injection is reduced, and the quality of the composition is stable.

Description

technical field [0001] The invention relates to the technical field of pharmaceutical preparations, in particular to an ambroxol hydrochloride injection composition and a preparation method thereof. Background technique [0002] Ambroxol hydrochloride is a respiratory mucus regulator, which can promote the elimination of viscous secretions in the respiratory tract and reduce the retention of mucus, thus significantly promoting expectoration and improving respiratory conditions. It is widely used clinically for various acute and chronic respiratory diseases. Thick sputum, difficulty expectoration, etc. Its chemical name is trans-4-[(2-amino-3,5-dibromobenzyl)amino]cyclohexanol hydrochloride, and its structural formula is: [0003] [0004] Ambroxol hydrochloride tastes sharply bitter and numb, with long-lasting bitterness and numbness, and it cannot be masked by adding sweeteners and flavoring agents routinely, and has low oral bioavailability and slow onset, so it is wid...
