Abstract

The invention particularly relates to a method for preparing a compound paracetamol and amantadine hydrochloride tablet, which belongs to the field of medicines. According to the method, submicron powder and ordinary fine powder which has been sieved with a 100-mesh sieve are mixed in proportion, a proper amount of accessories are added, and a prepared finished product is enabled to have better dissolvability, more than 90% on average. After six-month accelerated normal temperature stability experiments, the dissolvability of the finished product prepared by using the method is about 90%, and all the other indexes of the finished product accord with quality standard requirements.

Description

technical field [0001] The invention relates to the field of medicines, in particular to a method for preparing compound acetaminophen tablets.
