Problems solved by technology

[0003] The content of total astragalosides in Astragalus injection currently used clinically is not high, and the difference is large, and the drug effect is not easy to control; at the same time, because the content is not high and there are many impurities, patients have many adverse reactions after taking medicine, especially when taking medicine for injection. The problem becomes more prominent
[0004] Due to the poor water solubility of total astragalosides, it is difficult to obtain stable and satisfactory preparations when preparing its injections (small injections, powder injections, glucose infusions and sodium chloride infusions)

Abstract

The present invention is general astragaloside injection and its preparation process. The present invention screens some co-solvent and co-solving diluent including propylene glycol, ethanol, glycerine, polyglycol, benzyl benzoate, dimethyl acetamide, etc. to increase the dissolubility of general astragaloside in water. Each injection contains general astragaloside 5-50 mg, and medicinal supplementary material including diluent, co-solvent, excipient, osmotic pressure regulator, etc. The present invention has determined curative effect.

Description

technical field [0001] The invention belongs to the technical field of medicine, and specifically relates to a pharmaceutical preparation of total astragalosides, more specifically to a kind of injection of total astragalosides (including small injections, powder injections, glucose infusion and sodium chloride infusion). It relates to a preparation method of the preparation. Background technique [0002] Astragalus is a traditional traditional Chinese medicine that invigorates qi and strengthens the surface, diuretics and toxins, drains pus, and suppresses sores and promotes granulation.
