Abstract

The invention provides an oral liquid preparation of pidotimod, which can promote immunoreaction of a human body, effectively reduces times and degree of treating acute attack of bacteria or virus induced infection, shortens the course of the disease, can serve as an auxiliary medicine of antibiotic during acute infection and belongs to the field of medicines. The oral liquid preparation comprises the pidotimod, a chemical stabilizer, a pH regulator, a flavoring agent and the like, wherein trihytdroxy methyl-aminomethane serves as the pH regulator; and stability of the solution can be effectively improved through quantitative proportion and synergistic effect of each ingredient. The oral liquid preparation has stable quality, is convenient to store for a long time and is particularly suitable for old people or children to take.

Description

technical field [0001] The invention relates to an oral liquid preparation containing pidotimod, which belongs to the field of medicines. Background technique [0002] The immune response in the human body exists in the occurrence and development of many diseases, including specific immune response and non-specific immune response, which directly affects the health of the human body. Pidotimod is a safe and effective immune function enhancer, which can promote both specific immune response and non-specific immune response. Animal experiments and clinical experiments have shown that although pidotimod has no direct antibacterial and antiviral activity, it can significantly play a role in treating bacteria (pneumococcus, Escherichia coli, Pseudomonas aeruginosa, Proteus, etc.) ), fungus, virus (influenza virus, herpes simplex virus, myocarditis virus and Menge virus, etc.) It can effectively reduce the number and degree of acute attacks and shorten the course of the disease....
