Abstract

The invention relates to a preparation method of a compound pseudoephedrine hydrochloride capsule. The preparation method provided by the invention is characterized by comprising the following steps of detecting chloroacetic acid content of sodium carboxymethyl starch, when the weight of chloroacetic acid is 0 to 0.05% of that of sodium carboxymethyl starch, mixing active ingredients and auxiliary materials well, carrying out granulation, drying, sieving and loading to obtain the compound pseudoephedrine hydrochloride capsule. Through the preparation method provided by the invention, it is avoided that chlorphenamine maleate and chloroacetic acid of the compound pseudoephedrine hydrochloride capsule undergo a chemical reaction in storage to produce an impurity shown in the formula I and thus chlorphenamine maleate content is reduced. The preparation method provided by the invention reduces factors causing preparation destabilization and improves preparation safety.

Description

technical field [0001] The invention relates to a preparation method of Ammamimin capsules, in particular to a method for controlling the content of chloroacetic acid in sodium carboxymethyl starch and a detection method thereof, belonging to the technical field of pharmaceutical preparations.
