Description

technical field

[0001] The invention relates to the field of medicine, in particular to an oral solution of an EV71 virus and CVA16 virus inhibitor (TJAB-1099) and a preparation method thereof. Background technique

[0002] Human hand-foot-mouth disease (HFMD) is a common acute infectious disease and is distributed all over the world. The incubation period of hand, foot and mouth disease is 2-10 days, with an average of 3-5 days, and the course of disease is generally 7-10 days. Fever symptoms appear at the onset of the disease, scattered herpes appear on the oral mucosa, maculopapules and herpes appear on the hands, feet and buttocks, and there may be inflammatory flushes around the herpes, and there is less fluid in the pustules. Accompanied by cough, runny nose, loss of appetite and other symptoms. In a small number of cases, especially children with EV71 infection, meningitis, encephalitis, encephalomyelitis, neurogenic pulmonary edema, and circulatory disorders may oc...

Examples

preparation example Construction

[0024] The method for preparing the oral solution of EV71 virus and CVA16 virus inhibitor (TJAB-1099) provided by the invention may further comprise the steps:

[0025] First, EV71 virus and CVA16 virus inhibitor (TJAB-1099) were dissolved in a solvent to prepare a mixed solution. Wherein, the solvent includes a combination of one or more of polyethylene glycol, glycerin and Tween, and ethanol and water. In this step, dissolve TJAB-1099 in ethanol, stir until completely dissolved, add glycerin, polyethylene glycol or Tween, mix well, and then add water to dissolve TJAB-1099 in the solvent. In this step, the solvent includes a mixture of 5% to 25% polyethylene glycol (if any), 5% to 30% glycerin (if any), and 1% to 20% Tween (if any). A combination of one or more and 10% to 50% ethanol and 10% to 50% water. Among them, 200-300 mg of TJAB-1099 is dissolved in 100 mL of solvent.

[0026] Second, add auxiliary materials to the above mixed solution. Among them, auxiliary materi...
