[0218] Take about 600ml of water for injection (or glucose isotonic solution), boil it, add a mixture containing 2000mg neohouttuyfonate sodium, 5g Tween-80, and 50mg glycerin, stir to dissolve, add water for injection (or isotonic solution) to 900ml, adjust pH5.0-6.2, stir to dissolve, filter, add water for injection (or isotonic solution) from the container to the total amount, fine filter, test intermediate products, fill (can be small volume injection or large volume Injection, specifications 2ml / bottle, 5ml / bottle, 50ml / bottle, 100ml / bottle, 250ml / bottle, 500ml / bottle), 100 degrees Celsius, 30 minutes sterilization, clarity inspection, packaging, ready to use.

Embodiment 2

[0220] prescription:

[0221] Neohouttuydin Sodium 80mg

[0222] Tween-80 0.1g

[0223] Glycerin 50mg

[0224] Add water for injection to 1000ml

[0225] Take about 600ml of water for injection (or glucose isotonic solution), boil it, add a mixture containing 80mg neohouttuyfonate sodium, 0.1g Tween-80, and 50mg glycerin, stir to dissolve, add water for injection (or isotonic solution) to 900ml, adjust pH5.0-6.2, stir to dissolve, filter, add water for injection (or isotonic solution) from the container to the total amount, fine filter, check the intermediate product, fill (can be small volume injection or large volume injection) Volumetric injection, specifications 2ml / bottle, 5ml / bottle, 50ml / bottle, 100ml / bottle, 250ml / bottle, 500ml / bottle), 100 degrees Celsius, 30 minutes sterilization, clarity inspection, packaging, ready to use.

Embodiment 3

[0227] Weigh 6 g of hydroxypropyl β-cyclodextrin, place in 6 ml of distilled water, and stir to dissolve. Another 0.3 g of neohouttuyfonate sodium was added to the above-mentioned hydroxypropyl β-cyclodextrin solution, and stirred or ground at room temperature for 30 minutes to obtain neohouttuyfonate sodium solution. (The weight ratio of drug to hydroxypropyl β-cyclodextrin is 1:20). Concentrate this solution to 5ml to obtain 60mg / ml neohouttuydin sodium solution.

Abstract

The invention relates to vein injection and its preparing method, which contains effective quantity of cosolvent, injected solvent or isoosmotic solution and excipient and pH conditioning agent can be added into if there is need.

Description

Technical field: [0001] The invention relates to a new houttuyfonate sodium intravenous injection and a preparation method thereof. Background technique: [0002] Neo-Houttuyninum sodium (Neo-Houttuyninum) synthesized by chemical method, the chemical name is lauryl acetaldehyde sodium bisulfite, and the active ingredient in natural Houttuyninum (Houttuyninum) sodium houttuydinum, chemical The name is the same series of sodium bisulfite adducts of decanoyl acetaldehyde, and the pharmacological effects and curative effects of the two are basically similar. At present, the preparation made of new houttuyniatin sodium is new houttuyniatin sodium injection, which is now recorded in "Guangdong Provincial Drug Standards" (1987 Edition Volume 2), page 1177-1178, and this variety is an antibacterial and anti-inflammatory drug . It is a chemical synthesis of an aldehyde component in the volatile oil of the whole herb of Houttuynia sulfite. It has obvious inhibitory effect on pneumo...
