Problems solved by technology

[0007] In addition, "Chinese Pharmaceutical Excipients" (Chemical Industry Press, 2006 edition, edited by Luo Mingsheng, etc.) discloses that sodium carboxymethyl starch is best when added externally, while microcrystalline cellulose is usually not suitable for use as a disintegrant
[0008] Erdosteine ​​dissolubility is relatively poor, and the bioavailability of making common dosage form is relatively poor, therefore, the present invention has carried out a large amount of experimental studies on the basis of above-mentioned disclosed literature, has proposed Erdosteine ​​dispersible tablet of the present invention and its preparation method

Abstract

The invention provides an Erdosteine composition which consists of the following components by weight portions: 130 to 170 portions of Erdosteine, 35 to 65 portions of lactose, 30 to 70 portions of microcrystalline cellulose, 20 to 40 portions of low substituted hydroxypropyl cellulose, 1 to 5 portions of acesulfame, 10 to 30 portions of sodium carboxymethyl starch and 0.1 to 0.5 portions of magnesium stearate; the invention also provides a preparation method of the Erdosteine composition, comprising the following steps of: preparing materials and pelleting; mixing the Erdosteine and the low substituted hydroxypropyl cellulose evenly, then grinding, adding the sodium carboxymethyl starch, adding absolute ethyl alcohol, wet-mixing, cutting, drying, granulation and tabletting; mixing granules and microcrystalline cellulose evenly, adding the lactose, the acesulfame and the magnesium stearate for pelleting, subpackaging and obtaining the Erdosteine composition. The Erdosteine compositionhas good dispersible uniformity and high drug dissolution efficiency.

Description

technical field [0001] The invention relates to the field of medicine, in particular to an erdosteine ​​composition and a preparation method thereof. Background technique [0002] Phlegm is the product of respiratory inflammation, which can irritate the respiratory mucosa, cause cough and asthma, and aggravate infection. When patients with acute and chronic bronchitis or chronic lung disease have respiratory failure, if the patient's sputum is too viscous or forms sputum plugs, it can block the airway and cause suffocation. Therefore, it is of great significance to use mucus sputum regulators to dissolve mucus sputum, make it thinner, lower its viscosity, accelerate the movement of mucous membranes and cilia in the respiratory tract, and improve the transport function. [0003] The currently marketed mucus regulators, such as bromhexine, sodium thioethanesulfonate, and carbocysteine, all have varying degrees of mucus regulation, but they have some pharmacological or clinica...
