Abstract
The invention relates to an in-situ gel preparation of potassium dehydroandrographolide succinate and a preparation method thereof. The preparation is prepared from potassium dehydroandrographolide succinate (dehydration andrographolide butanedioic acid ester single sylvite half), in-site gel substrates recognized in the field, and other pharmaceutic adjuvants necessary for other pharmacy by using water as a solvent. In-situ gel of potassium dehydroandrographolide succinate is liquid freely moving outside a body, and forms semisolid gel after patients take the gel. The invention has the advantages of definite effect, stable performance, simple preparation, convenient administration, strong compliance for patients, no toxic and side effect, no untoward effect, high bioavailability, and on the like. The in-situ gel preparation has good antipyretic and antiinflammatory action, can be used for clinically treating viral respiratory tract infection and viral pneumonia, can be used as alternative medicine for potassium dehydroandrographolide succinate injection, and is particularly suitable for infants and patients who have trouble in taking medicine.
Description
Technical field: [0001] The invention belongs to the field of traditional Chinese medicine, and more specifically relates to a Chuanhuning in situ drug with good antipyretic effect and anti-inflammatory effect, which is the first choice for viral upper respiratory tract infection and viral pneumonia, especially for infants and patients who are inconvenient to take medicine. Gel formulation and method for its preparation. Background technique: [0002] In recent years, with the large-scale clinical application of traditional Chinese medicine injections, the problem of adverse reactions has become more and more prominent. The 10 varieties of leaf saponin sodium, puerarin and zedoary oil injection were more serious, and their adverse reaction rate accounted for 74.4% of all traditional Chinese medicine injections. Incidents of anaphylactic shock and acute death caused by adverse reactions of traditional Chinese medicine injections have been reported from time to time (Zuo Zhiy...
