Description

technical field [0001] The invention relates to a Yanhuning / Chuanhuning liposome combination medicine and a preparation method thereof. Background technique [0002] Yanhuning and Chuanhuning are metabolized into the same substance in the body, which are antiviral drugs and also have antipyretic and anti-inflammatory effects. No resistance to western medicine antibiotics. Moreover, Yanhuning / Chuanhuning is also an antiviral drug that can be applied to children. [0003] Adverse reactions of Yanhuning / Chuanhuning have been found in clinical application, ranging from skin rash in mild cases to dyspnea, edema, and even shock in severe cases. Adverse reactions such as digestive tract, blood system, and pyrogenic reactions were also found. [0004] The reason for these adverse reactions is the conjugation effect between the carbon-oxygen double bond and the carbon-carbon double bond in the chemical structure. In the process of preparation, storage, transportation and use, the ...
