Description
Technical field
The present invention relates to a kind of antiviral Western medicine and make field, the particularly preparation method of arbidol HCl sheet and method of quality control thereof.
Background technology
The antigen transmutability of influenza virus and many tolerations of acute respiratory viral infection hamper people and obtain the vaccine of a safe enough to treat and to prevent this class disease.For these reasons, some uncertainty of the application of gamma interferon.In this field, chemotherapy influenza and the sense of acute respiration sexually transmitted disease (STD) poison played a part very important at that time.In modern practice, adamantane derivative such as amantadine have widely as antiviral substance to be used, yet, their narrow activity profiles (only acting on influenza virus A), sizable side effect and easily produce defectives such as toleration and reduced their clinical value.extensively seek treatment and the process of the antiviral drugs of flu-prevention and other acute respiratory viral infection in, arbidol HCl becomes final selection, it has immunomodulating simultaneously, disturbs and induce and antioxidative character.
The antiviral activity of arbidol HCl is primarily aimed at influenza virus A, Type B, and its pharmacologically active may be owing to activation 2, the 5-oligodenylate synthetase, and it does not stop the proteinic synthetic or transcription of virus-specific of A, Type B influenza virus.At the commitment of virus replication, Abiduoer shows the virus-specific effect, hinders viral lipoid envelope and cell membrane and merges.The Abiduoer selectivity suppresses duplicating of influenza virus A, B in cell cultivation process.Simultaneously macrophage phagocytic there is significant activation.Recent in addition studies show that, this medicine also has good inhibitory effect to SARS virus under lower safe concentration.
Domestic existing arbidol HCl capsule and granule listing at present, there is the condition of storage strictness in its product, and easily the moisture absorption is rotten, and production cost is higher, and the patient bears rate defective on the low side.Simultaneously, though the control method of bibliographical information to its quality arranged both at home and abroad, there is complex operation, to drawbacks such as having relatively high expectations of instrument and equipment.
Summary of the invention
The objective of the invention is to overcome the deficiency of the existing kind of arbidol HCl, the preparation method of a kind of broad-spectrum high efficacy, steady quality, technology is simple, with low cost, the patient is easy to accept arbidol HCl sheet is provided and provide a kind of simple and efficient, quantitatively accurately, the method for quality control of specificity is good, the suitability is strong arbidol HCl sheet.
The object of the present invention is achieved like this:
One, major ingredient weight ratio (1000 preparation units):
