Problems solved by technology

[0008] Although 1-deoxynojirimycin showed excellent broad-spectrum antiviral effect in vitro antiviral test, the unique chemical structure of 1-deoxynojirimycin makes it competitive with The combination of multiple glucosidases on the microvilli of small intestinal brush border cells is not enough to saturate the huge amount of glucosidases in the usual doses, so 1-deoxynojirimycin is almost ineffective when administered orally in the gastrointestinal tract. Absorb into blood, can not bring into play its good antiviral effect in human body and limit the application of 1-deoxynojirimycin in antiviral field, therefore need to solve the existing problem, make 1-deoxynojirimycin composition can enter blood and play an antiviral role

Abstract

The invention discloses a solid or liquid medicinal composition for non-gastrointestinal administration. The medicinal composition contains 1-deoxynojirimycin component and / or pharmaceutically acceptable salt thereof, and the 1-deoxynojirimycin component and / or the pharmaceutically acceptable salt thereof and a pharmaceutically acceptable carrier or excipient are prepared into the medicinal composition for non-gastrointestinal administration together. The medicinal composition for non-gastrointestinal administration can be injection, pills, sublingual tablets, oral patches, buccal tablets, respiratory inhalation aerosol, powder for inhalation, suppository and capsules for rectums and transdermal preparations. The medicinal composition can be used for preventing and / or treating virus infection of mammals comprising human in a non-gastrointestinal administration mode, and the composition has good broad-spectrum antivirus effect and high safety.

Description

technical field [0001] The invention relates to an antiviral pharmaceutical composition, which belongs to the technical field of pharmaceutical preparations, and specifically relates to an antiviral drug composition suitable for administration through injection, absorption through oral mucosa, absorption through sublingual vein, inhalation through the respiratory tract, administration through rectum, and administration through nasal mucosa. Absorption, absorption through the skin, and an antiviral therapeutic pharmaceutical composition for parenteral use such as eye medication. Background technique [0002] Viral infection and transmission have always been an important health problem threatening the world, and how to find effective broad-spectrum antiviral drugs for the prevention and treatment of viral infections has always been a hot topic in the medical field. Although there are a large number of antiviral drugs, their antiviral spectrum is broad However, there are very f...
