Abstract

The invention discloses an N-acetylcysteine pharmaceutical composition and a preparation method thereof. The pharmaceutical composition comprises an active component and excipients, wherein the active component is N-acetylcysteine and the excipients are cane sugar, sweet orange essence, aspartame, sunset yellow and flow aid. The preparation method is as follows: first, granulating the excipients of cane sugar, sweet orange essence, aspartame and sunset yellow and drying the obtained granules and then carrying out size stabilization to the dried granules; and then mixing with the active component N-acetylcysteine and the flow aid to obtain the granular N-acetylcysteine pharmaceutical composition. The granular N-acetylcysteine pharmaceutical composition provided by the invention is simple in preparation, wherein the raw material N-acetylcysteine is more stable, difficult to be destroyed, and is easy to mix with other excipients.

Description

technical field [0001] The invention relates to a pharmaceutical composition of acetylcysteine ​​and a preparation method thereof. Background technique [0002] The molecular formula of N-acetylcysteine ​​(NAC) is C5H9N03S. It is an acetyl compound of L-cysteine, which contains an active -SH group. It is a commonly used expectorant in clinical practice, and is also often used to rescue the liver toxicity caused by acetaminophen. In recent years, many literatures have reported that NAC, as a sulfhydryl donor, is also an antioxidant, which can interfere with the generation of free radicals, remove the generated free radicals, and regulate the metabolic activity of cells. It has been widely used in clinical and experimental research. Abroad, it is used as a therapeutic drug for acute fulminant liver failure (Acute Liver Failure) caused by drug poisoning. Its structural formula is as follows: [0003] [0004] Acetylcysteine ​​granule is an expectorant, and the people who...
