The purpose of pre-freeze is to make it under vacuum, to distil in order to fix product.As do not freeze reality fully, and it is external that product can emit bottle outlet during evacuation, causes the spray bottle, and final products do not have certain shape, belong to waste product; If temperature is crossed to hang down and is wasted energy again, prolong the subsequent technique operating time without reason, the design of pre-freeze has determined the quality of dry run and freeze-drying prods to a great extent.
Bottled freeze-dried products mainly be through with freeze dryer in shelf accomplish exchange heat, at the bottom of the shelf temperature, the temperature difference of shelf is big in medicine and the freeze dryer; Rate of temperature fall is fast more, and the degree of supercooling of solution and degree of supersaturation are bigger, and critical crystalline granularity is then little; Nucleation rate is fast more, can form the less thin ice crystal of the more size of granule easily, after the thin ice crystal distillation; The void size that forms in the material is less, and solubility is good after the lyophilizing.Otherwise if not cooling in advance, rate of temperature fall can form oarse-grained ice crystal soon, and ice crystal distillation back forms the aqueous vapor discharge channel, and the void size that forms in the material is bigger, and the product solubility is poor after the lyophilizing.The design cryogenic temperature is-40 ℃.Freeze drying box is cooled in advance-40 ℃, purpose is to strengthen the temperature difference of medicine and shelf.
In test, the inventor finds, if be placed directly in bottled medicinal liquor in advance on the dividing plate that is cooled to-40 ℃; When cooling under the big environment of the temperature difference, the medicinal liquid in the bottle up and down two parts can to produce thermograde poor, in the propulsive from bottom to top process of an ice face; Upwards migration of solute causes the solute of upper epidermis often more in the solution, and density is higher; And bottom density is less down, short texture.Thus; In the design of pre-freeze, solution is placed in the freeze drying box of the fridge that is cooled to-40 ℃, be incubated freezing 2-3 hour; Though because the design cryogenic temperature is lower; Shortened crystallization time to a great extent, shortened the solute migration time equally, improved greatly because the atrophy situation that density variation causes.
In order to reach better effect, the present invention preferably adopts staging pre-freeze, is about to medicinal liquid and places lyophilizing cabinet internal cooling to-3 ℃~-5 ℃ earlier from room temperature; Kept temperature 1-2 hour, this process makes temperature autobalance in the medicinal liquid; Eliminate thermograde, then, again medicinal liquid is cooled to-40 ℃; Freezing 2-3 hour, can reduce like this in the bottle medicinal liquid up and down two parts can to produce thermograde poor, to such an extent as to and make enough medicinal liquid whole crystallizations of moment greatly of boring energy accumulation; Prepared product solubility is splendid, and outward appearance is full, color even, hole fine and close, and is all better than the outward appearance, clarity and the stability that adopt direct pre-freeze method product.
The distillation phase can be removed about 90% moisture.During distillation, the upper materials drying that will take the lead in, too fast if its temperature rises; Might reach the temperature of caving in, porous skeleton rigidity reduces, and coming off appears in the granule in the drying layer; Can seal the micro channel of drying nest, stop the carrying out of distillation, rate of sublimation is slowed down; Even make underclad portion atrophy slightly, and influence the content of goods residual moisture, cause solubility, stability and clarity variation simultaneously.Temperature retention time is unsuitable long; Because the small crystals that the medicinal liquid quick freezing produces has very high surface energy; When heating, recrystallize might take place, mutually combining between the little ice crystal forms big ice crystal, makes its surface to volume ratio reach minimum; Big ice crystal makes the dried frozen aquatic products outward appearance bad, and solubility is poor.Therefore, the choice relation of sublimation temperature is to the speed of distillation, and excessive temperature or cross distillation for a long time or be incubated all has adverse effect to product.Different medicinal liquids are according to the difference of its physical and chemical performance, and it is also different with distillation time and temperature retention time to be fit to the freeze dried sublimation temperature of this medicinal liquid.The inventor proves through replica test: time and temperature design that the present invention selects sublimation stage to adopt can make the methionine of the present invention plain B that supports one's family
1Composite freeze-dried powder agent solubility, stability and clarity all reach optimization.Through the contrast experiment; Different sublimation temperature in the design medicinal liquid freeze-dry process, different distillation time and different temperature retention times, carry out lyophilizing respectively after, reuse sodium chloride or glucose solution dissolving; Through the clarity after contrasting the freeze-drying prods dissolving repeatedly between different sublimation temperatures, different distillation time and the different temperature retention time, solubility, carry out the assay of related substances again; Experiment show sublimation stage, be cooled to-45 ℃, evacuation reaches 10Pa and keeps heating up under the vacuum; Be warming up to-8 ℃~-5 ℃ at 10~12 hours; Keep-8 ℃~-5 ℃ about 6 hours, the final products that obtain in this scope, its clarity is best, solubility is best, related substances (being impurity) content is also minimum.Because experimental technique and detection method are the normal experiment method, can be referring to associated materials such as pharmacopeia or ministry standards, therefore, contrast experiment's operational approach owes to give with concrete data result here, can replenish evidence at any time when needing.Obviously be superior to like product.
Help the distillation of ice in the product though pressure is low, because pressure is when too low, unfavorable to conducting heat, product is difficult for obtaining heat, the rate of sublimation reduction.When pressure is too high, the product caloric receptivity will reduce, and the rate of sublimation of ice slows down in the product, all can cause the lyophilizing failure.Therefore, pressure is set at 8~10Pa, not only has been beneficial to the transmission of heat but also has been beneficial to the carrying out of distillation, also can shorten time distillation phase relatively.
Distillation finishes, because also there is the moisture about 10% in the product, reaches qualified remaining water content in order to make product, must be further dry to product, that is, get into drying stage.Dry run is incubated 1 hour for being warming up to 0 ℃, and 6-7 hour cascade raising temperature to 40~45 ℃ are incubated 3-5 hour.
The present invention adopts above-mentioned prescription, through above-mentioned process, and the methionine that the makes plain B that supports one's family
1The composite freeze-dried powder product appearance is full, and solubility is good, and is best in quality, and is suitable for suitability for industrialized production.
Freeze-dried powder composition and method of making the same of the present invention can improve the methionine plain B that supports one's family greatly
1No matter the stability of composite injection be the methionine plain B that supports one's family in configuration, packing or the freeze-drying process
1The related substance of composite injection does not all have increase, content and does not have obvious decline yet; This lyophilized injectable powder has good stability in transportation and storage process; Compatibility solution can be placed the long period during clinical use; Make clinically to become convenient, also having reduced greatly simultaneously increases the curative effect problem of descending and bringing to the patient for hidden danger that patient's drug safety brings and content because of impurity (related substance).
