Abstract

An oral disintegrating tablet of bromhexine hydrochloride is prepared through heating the water-soluble carrier for fusing it, mixing with bromhexine hydrochloride, stirring, granulating by extruding out, quick cooling, pulverizing, mixing it with filler, disintegrant, flowing aid and lubricant, and tabletting.

Description

technical field [0001] The invention relates to bromhexine hydrochloride oral rapidly disintegrating tablets and a preparation method thereof. Background technique [0002] Bromhexine hydrochloride is an expectorant, which is a semi-synthetic hydrochloride of the derivative of orchidine. It was first used as an active ingredient in the Indian folk expectorant and cough medicine Duckbill. It was first synthesized by Keck in 1963 and launched in 1965. , my country began production in 1973, and the pharmacopoeias of the United Kingdom, France, Germany, Holland, Switzerland, Italy, Portugal, and China have all been recorded. Bromhexine hydrochloride is white or off-white crystalline powder; odorless, tasteless, slightly soluble in water. Bromhexine hydrochloride can crack the polysaccharide fibers of acid glycoprotein in sputum, and can also reduce the synthesis of acid glycoprotein in the mucous glands and goblet cells of the respiratory tract, resulting in reduced sputum visco...
