Abstract

The invention relates to the technical field of pharmaceutical preparation, and particularly relates to a compound paracetamol and amantadine hydrochloride tablet and a preparation method thereof. The compound paracetamol and amantadine hydrochloride tablet is prepared from acetaminophen, mydantane, caffeine, chlorpheniramine maleate, artificial calculus bovis and a pharmaceutically acceptable auxiliary material, wherein the pharmaceutically acceptable auxiliary material is a mixture of two or more than two of starch, magnesium stearate, hydroxypropyl methylcellulose, sodium carboxymethyl starch and microcrystalline cellulose. According to the compound paracetamol and amantadine hydrochloride tablet and the preparation method thereof, through changing the variety and the proportion of an auxiliary material in an original prescription, the dissolution rate and the stability of the compound paracetamol and amantadine hydrochloride tablet are improved; the dissolution rate within 10 minutes can be as high as 95 percent or above; through a six-month acceleration and normal-temperature long-term stability test, the content is stabilized to be 95.0 percent or above, and is superior to that of the original prescription and other commercially sold products.
