Abstract
The invention relates to a method for preparing tinidazole and sodium chloride injection, which comprises the following steps of: performing thick mixing, heating, filtering, performing thin mixing, adjusting the pH value, filtering, filling, sealing, sterilizing, checking and the like. The tinidazole and sodium chloride injection prepared by the method has high stability, and can be packed in plastic bottles completely.
Description
Technical field
The present invention relates to a kind of preparation method of tinidazole sodium chloride injection, relate to a kind of preparation method of tinidazole sodium chloride injection of good stability specifically.
Background technology
Tinidazole is a third generation quinolones broad spectrum antibiotic, and its injection is used for the treatment of clinically by the microbial infection of sensitivity, determined curative effect.Because stability, the dissolubility of tinidazole sodium chloride injection are not fine, all adopt glass bottle packaging at present.But, the plastic bottle packing infusion products than glass bottle packaging infusion products have light weight, convenient transportation, body not cracky, be easy to guarantee product quality, adopt the pull-tab design to open characteristics such as bottle cap is convenient to be extensive use of in China medical institutions at different levels in recent years, welcome by vast medical and nursing work person; In addition, because plastic bottle body light transmission is weaker than vial,, can further increases product and imitate the phase this storage that concerning the easy analytical product of photaesthesia, is easier to of tinidazole.Therefore how to increase deliquescent its stability that guarantees simultaneously of tinidazole sodium chloride injection, making it can adopt plastic bottle packing is present pharmaceutical industry problem demanding prompt solution.
Summary of the invention
Technical problem to be solved by this invention provides a kind of preparation method of tinidazole sodium chloride injection, requirement through tinidazole sodium chloride injection that this preparation method makes improving the dissolubility of tinidazole in sodium chloride solution in, guarantee the stability of medicine, thereby can use plastic bottle packing.
For solving the problems of the technologies described above, the invention provides a kind of preparation method of tinidazole sodium chloride injection, comprise densely join, heating, filtration, rarely join, filter, regulate pH value and fill, seal, sterilize, step such as check.Heating steps in this preparation method helps increasing stability and the homogeneity of tinidazole in sodium chloride solution, avoids tinidazole dissolving not thorough, plastic bottle bottle wall naked eyes sightless concavo-convex on crystallization separate out.
Concrete preparation method is as follows:
(1) in handling clean dense preparing tank, add water for injection, opening under the dense preparing tank stirring state, with weighing accurately sodium chloride for injection gently pour in the dense preparing tank, make its dissolving, caking prevents to sink, the medicated powder application water for injection that sticks to tank skin washes down, treat all to add medicinal charcoal after the dissolving, stir, feed Steam Heating in the interlayer and boil.
(2) dense material after filtration after the carbon removal, is added dilute preparing tank, add water for injection simultaneously and open dilute preparing tank and be stirred in dense material and filter afterwards with water for injection and the medicinal liquid of remnants in the dense preparing tank is washed down and add in the dilute preparing tank.
(3) water for injection is added in the clean plastic containers, stir down slowly adding and claim fixed injection tinidazole, make it dissolving fully.To dissolve completely and slowly add in the dilute preparing tank under the solution stirring.
(4) water for injection filters through dense material and is added to dilute preparing tank, additional water for injection is to stipulating scale, add active carbon, use caustic lye of soda (2moL/L) or hydrochloric acid solution (2moL/L) to adjust pH value in case of necessity, sampling and measuring content and pH value, adjust in accordance with regulations qualified after, through titanium rod and 0.45 μ m, that 0.22 μ m micropore filter element is filtered to medicinal liquid is clear and bright, for embedding.
(5) mould bottle transfusion through the system bottle, (one-step method system bottle clean compressed air purge, two step method system bottle compressed air purge washes with water for injection the purge bottle at last.), for fill.
(6) seal after moulding bottle transfusion fill.
(7) mould 115 ℃ of water-bath sterilizations of bottle transfusion 32 minutes.
(8) check.
Described heating steps was kept 5 minutes for feeding is steam heated to 100 ℃.
Described adjusting pH value step is for regulating pH value 3.7～5.3.
The specific embodiment
Further specify the present invention below by embodiment.(all calculating) with single dose
Embodiment:
Preparation method:
1, in handling clean dense preparing tank, add about 1/2 amount water for injection,, gently pour into the 9kg sodium chloride for injection in the dense preparing tank opening under the dense preparing tank stirring state, make its dissolving, prevent from caking, the medicated powder application water for injection that sticks to tank skin washes down, and treats all to add medicinal charcoal 0.05% (W/V is with rare stereometer of joining) after the dissolving, stir, feed Steam Heating in the interlayer and boil, and keep boiling 5 minutes, close vapour.
2, dense material after filtration after the carbon removal, is added dilute preparing tank, add water for injection simultaneously and open dilute preparing tank and be stirred in dense material and filter afterwards with water for injection and the medicinal liquid of remnants in the dense preparing tank is washed down and add in the dilute preparing tank.
3, an amount of water for injection is added in the clean plastic containers, stir down slowly adding and claim fixed tinidazole, make it dissolving fully.To dissolve completely and slowly add in the dilute preparing tank under the solution stirring, stir.
4. water for injection filters through dense material and is added to dilute preparing tank, estimate that liquid level is when scale, stop to stir, additional water for injection stops to add water to stipulating scale, adds 0.01% (W/V is with rare stereometer of joining) medicinal charcoal, use caustic lye of soda (2moL/L) or hydrochloric acid solution (2moL/L) to adjust pH value in case of necessity to 3.7-5.3, adjust in accordance with regulations qualified after, through titanium rod and 0.45 μ m, that 0.22 μ m micropore filter element is filtered to medicinal liquid is clear and bright, for embedding.
5, mould bottle transfusion through the system bottle, (one-step method system bottle clean compressed air purge, two step method system bottle compressed air purge washes with water for injection the purge bottle at last.), (loading amount is controlled at 100ml～102ml) for fill.
6, seal after moulding bottle transfusion fill.
7, mould 115 ℃ of water-bath sterilizations of bottle transfusion 32 minutes.
8, check.
Claims (5)
1. the preparation method of a tinidazole sodium chloride injection, comprise densely join, heating, filtration, rarely join, regulate pH value, filtration and fill, seal, sterilize, step such as check.
