Problems solved by technology

[0006] CN102000030A discloses a dry suspension of Arbidol used in the medical and health industry and its preparation method. After the invention adopts a wet granulation process to make the dry suspension of Arbidol, it effectively covers the The bitter taste of Abidol greatly improves the patient's compliance, but the raw material of Abidol is not resistant to high temperature, so the wet granulation and drying process has risks to the quality of the variety
[0007] CN101904826A discloses an orally disintegrating tablet of arbidol hydrochloride and its preparation method. The invention has simple process control, fast absorption, high bioavailability, and is convenient to take. However, the process adopts the process of granulation and coating. It is cumbersome, the production parameters are not easy to control, and it is not conducive to industrialization
However, the sustained-release tablet releases the drug slowly, and cannot release the active ingredient of the drug quickly, so that the maximum blood drug concentration is low.
[0015] CN100367957C discloses a preparation for intravenous administration of arbidol and its salt and its preparation method. This method improves the bioavailability of the drug, but the salt formation process of this technology is complicated, and there is no arbidol that meets the national standard in China. Salt raw material, not conducive to industrialization
[0016] CN101066248 discloses a kind of Arbidol granules and preparation method thereof, the method adopts granule coating technology, although the bitter feeling brought by raw materials is improved, but adopts polymer coating technology, delays the release of medicine, reduces the The bioavailability of the drug cannot reach the expected drug effect
[0017] CN101249076 discloses a kind of Arbidol granule preparation and its fluidized bed coating preparation method, the method uses a fluidized bed to coat the granule intermediate, but uses a fluidized bed to coat the granules. The dry mixing process of Dole and its salt dry suspension is more cumbersome and complicated, and the parameters are difficult to control, which is not conducive to the industrialization of this variety

Description

technical field [0001] The invention relates to the field of pharmaceutical packaging, in particular to arbidol and its salt dry suspension and a preparation method thereof. Background technique [0002] Arbidol is a highly effective drug for preventing and treating type A and type B influenza and other acute respiratory virus infections. The mechanism of action is different from commonly used clinical antiviral drugs such as ribavirin, amantadine and rimantadine; it induces interferon and enhances immune function to fight against influenza virus; All of them have antagonism effect, and have a wider antiviral spectrum than amantadines, and also have the effect of activating macrophages, and can effectively treat influenza and other acute respiratory virus infections. Recent studies have shown that the drug also has a better inhibitory effect on atypical viruses at a lower safe concentration. Arbidol hydrochloride has very low toxicity. Foreign literature reports that rats ...
