Description
Technical field
The present invention relates to a kind of solid formulation for dialysis that is used for modulating the bicarbonate dialysis liquid system that renal failure patient dialysis therapy uses; In particular to a kind of solid formulation for dialysis and preparation method thereof, the plocoid coating that is contained specific salts as the surface of the particle (coatingparticles) of parent nucleus during described solid preparation pelletize coats, and its stability, content uniformity and wearability are all good.
Background technology
Dialysis therapy has been asserted a kind of method for the treatment of the renal failure patient, and this method is implemented with the form that continues treatment regularly for getting rid of refuse in the body, regulating electrolytical purpose.In order to the dialysis solution of dialysis therapy, be to form according to the composition modulation that is similar to the normal serum electrolyte concentration, in recent years in, adopt the few hydrocarbonate dialysis agent of burden concerning organism.For bicarbonate dialysis liquid system, because sodium bicarbonate and calcium chloride or magnesium chloride produce carbonate deposition, so, generally speaking, to contain calcium chloride or magnesium chloride but do not contain the preparation (A agent) of sodium bicarbonate and contain sodium bicarbonate but two kinds of preparations of preparation (B agent) of not containing calcium chloride or magnesium chloride separately, before use respectively the dissolving, diluted mixture, be modulated into bicarbonate dialysis liquid system.
Now, the main preparation type that uses in hemodialysis has following 3 kinds: " powder-powder type " of " liquid-liquid type " of concentrated stock solution A+ concentrated stock solution B, " liquid-powder type " of concentrated stock solution A+ powder B (sodium bicarbonate) and powder A+ powder B.In " liquid-liquid type ", " liquid-powder type ", for the concentrated stock solution preparation, the concentrated stock solution about 10kg of normally in the polyethylene container made, packing into, therefore, volume is big and heavy, in transportation, carrying, memory space, using method, exist variety of problems with the aspects such as waste treatment of back container.
In order to address these problems, in recent years, to develop and a kind ofly A agent powdered is obtained " powder-powder type " solid preparation and be applied.Medical treatment is on-the-spot in hospital etc., can use special-purpose dissolver, in case this solid preparation is dissolved as stock solution with the concentrated stock solution same concentrations of " liquid-liquid type ", can continue dissolving, dilution then, is modulated to the concentration of dialysis solution.
The preparation method of such solid preparation, known in the prior art have: spray drying method, wet granulation, dry pelletizing method etc.Every kind of method has its pros and cons, do not reach satisfied degree talkative aspect preparation method or the quality.With preparation that spray drying method is obtained, volume is big, moisture and inhomogeneous, the sour composition volatilization of granularity, therefore is difficult to the pH value that reaches certain.On TOHKEMY 2002-102337 communique, the double-formulation solid shape bicarbonate dialysis that uses rotation stirring fluidized bed prilling granulator the to be obtained preparation method of preparation is disclosed, still, in the method, collide between the mobile pelletize thing, therefore the shortcoming that exists coating to be easy to come off.Simultaneously, owing to contain in the electrolyte ingredient of some sodium chloride and the water that glucose is dissolved in a great deal of, therefore must carry out spray drying, thereby energy unit consumption is significantly worsened.In wet granulation and the dry pelletizing method,, can't avoid pulverizing in order to keep uniformity, numerous and diverse step such as mixing, exist from device therefor or the outside shortcoming of sneaking into impurity and very easily polluting.
So, be conceived to these problems, need not the preparation method of numerous and diverse steps such as pulverizing, the scheme of the good compact-type solid preparation of bulk density, angle of repose and dissolution velocity has been proposed.For example, once the artificial kidney perfusion that open graininess that is made of the pelletize thing or granuliform bicarbonate are used to dialyse is with the preparation method (with reference to No. 2769592 communique of special permission) of A agent, the pelletize thing obtains through the following step: various electrolyte compounds are mixed, heat (73 ℃) in the presence of sodium acetate, water, add glucose then, mix with acetic acid, several sodium chloride particles are by this coating combination.In addition, solid-state dialysis preparation (with reference to No. 2987488 communique of special permission) was once disclosed, described solid-state dialysis preparation carries out pelletize at 60 ℃, double-layer structure with stratum nucleare and double salt layer, stratum nucleare comprise be selected from sodium chloride and potassium chloride at least a material as main component, the double salt layer contains double salt, other electrolyte compositions and the pH regulator agent that the reaction of sodium acetate and calcium chloride forms.
But, exist serious problems in these preparation methoies.In other words, in No. 2769592 communique of special permission, sodium chloride, potassium chloride, magnesium chloride, calcium chloride mix, stir, heat with pure water, add sodium acetate and continue to heat when mixing; In No. 2987488 communique of special permission, sodium chloride, potassium chloride, magnesium chloride, sodium acetate mix, stir, heat with pure water, add calcium chloride and continue to heat when mixing; In either case, content all can produce specific viscosity, causes viscosity obviously to increase, and stirs difficulty.Adopt general agitating device to be difficult to be prepared, need the extremely strong equipment of stirring capacity, because of the particularization of equipment, maximize so, the problem that exists the preparation expense obviously to increase, therefore thirst for a kind of both can be at a low price and the preparation of easy manufacture.
In addition, open in the 2002-102337 communique No. 2769592 communique of special permission, No. 2987488 communique of special permission and spy, all need be in long-time heating more than 60 ℃, in granulation process, breakdown of glucose, painted probability are very big, and there is the danger of variation in the content uniformity of the dialysis preparation that obtains by said method.And then, preparation according to this preparation method preparation, its coating reason fine particle by adhesive attachment, be laminated, so be vulnerable to the influence of external cause, so have the decomposition of glucose, the painted shortcoming that further develops of As time goes on being easy to, aspect storage stability, exist big defective.
And then because the constructional characteristic of coating, coating comes off easily when transportation, becomes the preparation of easy generation fine powder, adds the generation electrostatic interaction, causes the appearance of various problem.For example, during filling product, produced static in the time of airborne dust in process of production, the problem that sealing-strength reduces appears in the mouth-sealed portion branch absorption fine powder of packaging bag, and the worst situation is the danger that broken bag is arranged.On the other hand, in dialysis execute-in-place process, can kick up during the modulation dialysis solution and contain the dust of acetic acid, this also can produce because electrostatic effect makes solid preparation easily remain in problem in the bag when causing working environment to worsen.Also have, the outside of packaging material is because electrostatic effect also can be adsorbed foreign body, and one of reason that impurity is sneaked into when becoming dissolving is demanded urgently improving.
The purpose of this invention is to provide the fabulous solid formulation for dialysis of a kind of operation, described solid preparation comprises the necessary electrolyte of modulation bicarbonate dialysis liquid system, glucose and pH regulator agent, even wherein in fabrication stage, memory phase, glucose is stable existence also, acomia estranged separating and painted danger, have superior storage stability, content uniformity, wearability, dissolubility, powder attitude thing is also few, and has prevented electrostatic generation.
