Abstract

The invention relates to the field of medicine, and specifically relates to a preparation process of Aidi injection preparation. The invention uses cantharides, ginseng, astragalus and acanthopanax as raw materials. First, the ginseng is soaked in warm temperature and then alcohol-extracted. Then the ginseng medicinal residue is boiled with water and extracted with astragalus and acanthopanax. After the extract is combined, alcohol is carried out multiple times. , water is alternately precipitated and refrigerated to allow the impurities to fully precipitate and be removed, which greatly reduces the impurities in the liquid and reduces the incidence of adverse reactions. Then adjust the pH, ultrafiltrate, and refrigerate until use; After warm soaking, water extraction is carried out, and then treated by the lime sulfur method. After two alcohol precipitations, it is refrigerated, filtered, and water sedimented twice to adjust the pH, refrigerated, and ultrafiltrated. Finally, the cantharides extract is mixed with ginseng, astragalus, and acanthopanax. After mixing the extract, add excipients and adjust the pH. Finally, a preparation process for Aidi injection preparation with high extraction efficiency and purity and low incidence of adverse reactions was obtained.

Description

technical field [0001] The invention relates to the field of traditional Chinese medicine pharmacy, in particular to a preparation process of Aidi injection preparation. Background technique [0002] Traditional Chinese medicine injection preparations are sterilized preparations made from Chinese medicinal materials through extraction, separation, refining and other steps. It has changed the traditional way of administering traditional Chinese medicine. It has rapid drug effect, high bioavailability, and more accurate dosage. It is suitable for cases that are not suitable for oral administration or acute and severe cases. It has played a good role in the treatment of acute, severe and difficult diseases by traditional Chinese medicine. However, with the increasing clinical application, the incidents of adverse drug reactions caused by traditional Chinese medicine injections have occurred frequently, which has attracted the attention of the majority of medical workers. The ...
