Abstract

The invention provides high concentration pidotimod oral liquid, which can promote human body immune response, effectively reduces times and degree of acute attack of infections caused by bacteria or virus, shortens disease course, can serve as auxiliary medicine antibiotic of acute infection and belongs to the field of medicines. The oral liquid contains constitutions of pidotimod, chemical stabilizer, a potential of hydrogen (pH) adjusting agent, a flavoring agent and the like. Tris-(hydroxymethyl)-aminomethane is used as the pH adjusting agent. The oral liquid is stable in quality and convenient to store for a long time. By means of quantitative proportioning and synergistic effect of all constitutions, when the concentration of the oral liquid is improved, simultaneously the stability and taste of the oral liquid are obviously improved. The oral liquid doesn't contain sugar capable of being absorbed and used by human bodies and is suitable for the old and children.

Description

technical field [0001] The invention relates to an oral liquid preparation containing high-concentration 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 cou...
