At the same time, it provides a non-injection route for oligonucleotide drugs, because the oral effect of oligonucleotide drugs is low, and they are only limited to injection administration, and there are no research results on other ways of drug administration. Application of glycosides opens up a new avenue

[0070] FT 2.0g, paraben complex ester (respectively weigh an appropriate amount of paraben ethyl and propyl paraben, and mix the two at a ratio of 1:1 to obtain a paraben complex ester, the same below) 0.15g, Propylene glycol 3.5g, PBS (pH7.4) buffer (that is, phosphate buffer (pH7.4): take 1.36g of potassium dihydrogen phosphate, add 0.1mol / L sodiumhydroxide solution 79ml, dilute to 200ml with water, that is obtained. The same below) was added to 100ml.
[0071] Preparation method: Weigh 2.0g FT and dissolve it with 1.7ml PBS (pH7.4) buffer solution, pour it into the preparation tank, add 3.5g propylene glycol, stir, let it stand, filter, and then use buffer solution PBS (pH7.4) in the filtrate ) buffer solution to a final volume of 100ml, and finally add paraben complex ester, stir evenly, let stand, filter, potting, and sterilize to obtain.
[0073] Add 2.0 g of FT, 0.2 g of ethylparaben, 2.0 g of propylene glycol, 2.50 g of hydroxypropyl β-cyclodextrin, and add PBS (pH7.4) buffer solution to 100 ml.
[0074] Weigh 2.0g of FT and 2.5g of hydroxypropyl β-cyclodextrin, dissolve them with 1.7ml and 4.17ml of PBS (pH7.4) buffer solution respectively, inject them into the preparation tank, add 2.0g of propylene glycol, stir, stand still, and filter. Then add PBS (pH7.4) buffer solution to the filtrate to a final volume of 100ml, and finally add ethylparaben, stir well, let stand, filter, pot, and sterilize to obtain.
[0076] Add FT 2.0g, methyl paraben 0.25g, glycerin 4.2g, and normal saline to 100ml.
[0077]Weigh 2.0g of FT and dissolve it with 1.85ml of normal saline, inject it into the preparation tank, then add 4.2g of glycerin, stir, let stand, filter, add the filtrate to the final volume of 100ml with normal saline, finally add methylparaben, stir Mix evenly, let stand, filter, pot, sterilize, and you get it.

Abstract
The invention provides a nasal administration preparation which takes an antisense oligonucleotide medicament flutide (of which the sequence is 5'-CCTTGTTTCTACT-3') as a main component and is used for preventing and treating H1N1, H3N2 and H5N1 influenza virus infection, belonging to the field of chemical pharmacy. The nasal administration preparation takes the flutide as an effective component and also contains a proper amount of preservatives, buffer solution and medicinal auxiliary materials, and the pH value of the preparation is 7-8. The preservatives are reagents which can not influencethe physicochemical properties of medicaments and have no harm to human bodies, no irritation and no special odor under the inhibitory concentration. Common preservatives comprise methyl paraben, ethyl paraben, propyl paraben, butyl paraben, ethyl hydroxy benzoate, potassium sorbate, benzoic acid, benzalkonium bromide, chlorhexidine acetate, o-phenyl phenol, eucalyptus oil, cassia oil, peppermintoil and the like. The flutide nasal administration preparation has no irritation and very low toxicity, and is a medicament which has a high action speed and a lung targeting function when used for treating influenza.
Description
technical field [0001] The invention belongs to the field of chemical pharmacy, and is a nasal administration preparation mainly composed of an antisense oligonucleotidedrug influenza Tide (its sequence is: 5'-CCTTGTTTCTACT-3'), which is used for H1N1, H3N2 and H5N1 Prevention and treatment of influenza virus infection. Background technique [0002] Influenza is an acute, viral respiratory infectious disease that seriously endangers human life and health. There are large-scale outbreaks and epidemics in winter and spring every year, and each epidemic will cause 3 to 5 million severe influenza cases worldwide. Influenza virus has the characteristics of fast transmission, rapid mutation, and great harm. It is difficult to prevent vaccines. There are few types of anti-influenza drugs available, and they are particularly prone to drug resistance. According to WHO reports, for the main anti-influenza drugoseltamivir ( Drug-resistant mutant strains have appeared in many countri...
