Chemistry and thermally stable norastemizole formulations
The cross reference of related application
The application is to be that the part of pending application 08/851786 on May 6th, 1997 is follow-up the applying date, and the latter is that the part of pending application 08/824477 on March 26th, 1997 is follow-up for the applying date again, and the full content of two parts of applications all clearly is incorporated herein for reference.
Field of the present invention
The present invention relates to contain the chemistry and the heat-staple pharmaceutical composition of Tecastemizole (norastemizole).
Background of the present invention
The stability of many factor affecting drug products, the stability that comprises the medicine component, latent effect between medicine component and the inactive ingredients, preparation method, packing, the environmental condition that transport, storage and operating period is run into, preparation and use between time span and the type of dosage form.Except physical stability, should consider the chemical stability of drug products.For three chief reasons, the physics of pharmaceutical preparation and the knowledge of chemical stability are very important.
At first, drug products preferably should show freshly, exquisite and professional.Any change of physical appearance and color comprise fade, color change, fuzzy outward appearance or the like all can make patient that product is lost confidence.Secondly, because some product is prepared with multi-dose container, the uniform medicament of All Time internal therapy agent must be guaranteed.For example, uneven medicament pattern shows as turbid solution, has divided emulsion, the tablet of variable color or the capsule of variable color etc. of layer.The 3rd, in the whole storage life of dosage form expection, the medicine component must be able to be used by patient.Dosage form all can cause harmful change of the shortage or the medicine component bioavailability of bioavailability the destruction aspect physics or the chemical globality.
Various pharmaceutical dosage forms are successfully used to give many marketed drug.The conventional pharmaceutical dosage forms of listing in American Pharmacopeia/National Formulary (USP/NF) includes but not limited to aerosol, capsule, cachet, collyrium, cream, Emulsion, extractum, liquid extractum, gel, inhalant, injection, lotion, magma, milk, ointment, paste, pill or implant, powder, solution, ophthalmic solution, oral administration solution, otic solution, pastille, topical solution, spirit, suppository, suspending agent, Sublingual lozenge, syrup, tablet, tincture, lozenge, aromatic water etc.For oral administration, syrup, solution, suspending agent, lozenge, tablet and capsule are preferred.Yet in order to be easier to administration, easy to carry and patient is taken medicine according to the dosage of doctor formula, dragee, tablet and hard, soft capsule are most preferred.In some cases, tablet is preferable over capsule, because tablet is easier to swallow sometimes.
Typically, dragee, tablet and capsule comprise drug component, diluent and other excipient, as known in the art lubricant etc.For example known excipient comprises coating materials, coloring agent, desiccant, emulsifying agent, cosolvent, correctives, anti-caking agent (anti-caking), plasticizer, suspending agent, thickening agent, binding agent, diluent, wetting agent etc.
Lactose is normally used diluent or excipient.Spray-dired lactose is normally used lactose form, and it is widely used as the excipient of direct compression.Because the appearance of spray-dried lactose, it has also enlarged as the application of excipient.Spray-dried lactose is why such to be approved fastly, and partly cause is that its mixes in direct compression easily.In this was used, spray-dired lactose was the tabletting step that has and needn't further granulate or adopt complexity with its backup form.Spray-dired lactose also can be at an easy rate and is mixed into easily in dragee and the capsule.Spray-dired lactose can directly be added in the medicine, obtains needed thinner ratio thus.After this, for example, the mixture dry method of lactose and medicine tablet be can be pressed into, perhaps, if desired, dragee or capsule be made with other excipient.
Typically, all there are the balance between α type and the β type in spray drying or non-spray drying type lactose, and wherein, the change between these configurations is constantly ongoing.Alpha-lactose is the disaccharide that is made of β-D-galactose and alpha-D-glucose.Beta lactose is by β-D-galactose and disaccharide that β-the D-glucose constitutes.Beta lactose only exists with its anhydrous form, and alpha-lactose can obtain an anhydrous form or a hydrated form.
In the change process of α type and β type lactose, form the aldehyde intermediate, it is known that it is incompatible with most of primary amine.Primary amine is added to and forms imines on the carbonyl carbon of aldehyde (or ketone):
Figure A9880545700061
The incompatibility of most of primary amine and lactose is known.See Castello etc., J.Pharm.Sci., 51 (2): 106-108 (in February, 1962).Also see J.Pharm.Sci. such as Blaug, 61 (11): 1770-1775 (in November, 1972); Hartauer etc., Drug Dev.and Indust.Pharm., 17 (4): 617-630 (1991).
Castello etc. have tested the compatibility of amphetamine sulfate (a kind of primary amine salt) with lactose.They find that the mixture variable color gradually of lactose and amphetamine sulfate is particularly in the presence of alkaline lubricant such as magnesium stearate.Blaug etc. have tested dextroamphetamine sulfate (a kind of primary amine) and spray-dried lactose.They find that in the presence of dextroamphetamine sulfate, lactose forms Schiff alkali (being imines).Hartauer etc. have tested aminophylline and lactose, and find to exist between aminophylline and lactose some incompatibility, and particularly when heating down for about 60 ℃, this point can show by variable color.Aminophylline comprises the ratio of 2 molecule theophylline (secondary amine) and 1 molecule ethylenediamine (primary amine).Yet Hartauer etc. have tested these components and have found, are heating or be not heated under 60 ℃, and single theophylline (secondary amine) does not react with lactose, and ethylenediamine but reacts with lactose, particularly when being heated to 60 ℃.Therefore, the incompatibility of aminophylline and lactose is to be produced by primary amine component ethylenediamine in the aminophylline and lactose.
Medicine astemizole (secondary amine) is seemingly compatible with lactose, because it can HISMANAL , lactinated Tabules is bought from market.According to Physician ' s Desk Reference, 50th Edition, Medical Economics Co., Montvale, NJ, P.1293 (1996), every Hismanal Contain 10mg astemizole, lactose, corn starch, microcrystalline Cellulose, pregelatinized starch, 30 POVIDONE K 30 BP/USP 90, magnesium stearate, silica sol and sodium lauryl sulfate.
Similarly, expection Tecastemizole (main metabolites of another secondary amine and astemizole) should be compatible with lactose, particularly when not heating.It is reported that Tecastemizole is more effective and low toxicity than astemizole.Therefore, Tecastemizole is the medicine of attractive replacement astemizole in treat ing bronchial anaphylactic disease.Should be realized that astemizole and Tecastemizole all are the antihistaminics that contains the secondary amine part; Yet Tecastemizole has two secondary amine parts, and astemizole has only one.

The present invention describes in detail
Surprisingly, the applicant finds even in situation about not heating, the metachromasia that primary amine and lactose occur also exists in Tecastemizole. Therefore, at secondary amine, as if also there is undesirable incompatibility mentioned above between Tecastemizole and the lactose. So it is desirable preparing lactose-free Tecastemizole formulation. And the applicant finds that also the unstability of lactose and Tecastemizole can start because Tecastemizole/lactose preparation is exposed to water (comprising atmospheric moisture, such as humidity) and/or promote. Unstability is also because starting and/or promote being higher than under about 60 ℃ temperature heating. And the applicant finds that also the unstability of lactose and Tecastemizole can expose Tecastemizole/lactose preparation and start and/or promote because of the high surf zone of granule Tecastemizole commonly used in the pharmaceutical composition. In addition, the applicant finds that also the unstability of lactose and Tecastemizole can be by suppressing to the Tecastemizole granule coating or avoiding before preparation Tecastemizole and the excipient that reacts such as lactose.
In publication number is the embodiment 4 of PCT application PCT/US93/08349 of WO94/07495, propose the Tecastemizole preparation, wherein do not contain lactose. Among preparation A, the B and C of embodiment 4, all contain 1.0% weight dolomol BP, the starch 1500 that contains respectively 94.0,89.0 and 79.0 % weight (can be from Colorcon, the starch,pregelatinized that Ltd buys), the remainder of composition is the metabolin (such as, Tecastemizole) of astemizole. Yet, in practice, do not prepare or use the preparation of lactose-free embodiment 4, because dolomol BP and starch 1500 are inconsistent at described percentage by weight. In other words, the preparation of the disclosed embodiment 4 of this PCT is unsuitable for actual drug use. And the document is both not open does not advise that Tecastemizole and lactose are inconsistent yet, and this is because wherein embodiment 5 is the tablets that contain the Tecastemizole of lactose.
For mentioned above with comprise secondary amine, the undesirable problem that Tecastemizole is relevant with the lactose pharmaceutical preparation needs preparation avoid inconsistent stable Tecastemizole solid pharmaceutical preparation between Tecastemizole and the lactose. The present invention recognizes valuably and lactose-free Tecastemizole preparation is provided.
Because the pharmacological action of Tecastemizole is better than astemizole, need the Tecastemizole formulation of stability and high efficiency. Up to the present, there is not commercially available stable Tecastemizole preparation. Yet the present inventor is by eliminating lactose and using other component described herein to find, the lactose-free formulation of Tecastemizole all is stable on chemistry, physics and thermodynamics unexpectedly. The present invention can obtain this stability and not affect easiness and the medicament characteristic of preparation.
Therefore, feature of the present invention provides stable pharmaceutical preparation on chemistry and thermodynamics, and it comprises Tecastemizole or its officinal salt and a kind of pharmaceutically suitable carrier or excipient, and described carrier or excipient do not comprise or do not use any type of lactose. Because produce easily, lactose is widely used for pharmaceuticals industry especially. Yet the applicant finds valuably, the preparation that comprises Tecastemizole and lactose As time goes on unstable and when meet heat and when moist degraded faster.
Thought before that secondary amine was compatible with lactose, particularly at room temperature or in the situation of being heated minimum (for example being lower than about 60 ℃) or keeping from heat. For example, as mentioned above, the medicine astemizole can commodity Hismanal by name, contain lactose and other excipient Tabules and buy.
Find that at present physics and/or chemical incompatibility are present between secondary amine Tecastemizole and the lactose. Although without being limited by theory, be sure of that the incompatibility of Tecastemizole and lactose is to form enamine by reaction between the aldehyde intermediate of lactose and the secondary amine to cause:
Also find this incompatibility even be present under room temperature (for example, being lower than about 60 ℃ temperature) and the indoor relative humidity. In addition, the applicant has also found high stability pharmaceutical composition, and it comprises Tecastemizole and does not use the excipient lactose of extensive employing.
One of feature of the present invention provides lactose-free Tecastemizole pharmaceutical composition. These compositions have effective anti-histamine activity and are used for the treatment of various diseases. For example, these diseases comprise allergic rhinitis, asthma and other anaphylactia, dizzy, motion sickness, vestibular function imbalance (for example Meniere's disease), diabetes type retinopathy, other little vascular diseases relevant with diabetes.
The more important thing is, these lactose-free compositions provide stable and easily formulation in order to discharge Tecastemizole in human body. The lactose-free composition of the present invention is stable especially, and they have effective storage period. In addition, even run into slight temperature and room temperature variation, it is stable that the present composition still keeps. And although the present composition is lactose-free, said composition is easily preparation still, and said composition has needed Dose Characteristics. The present composition comprises the solid unit dose preparation, and it comprises Tecastemizole or its officinal salt and the pharmaceutically acceptable excipient of at least a non-lactose. Said composition also can comprise or not contain other treatment component, adhesive/filler, disintegrant, lubricant, anti-caking agent, anticorrisive agent, film coating agent, sweetener, colouring agent, flavouring, drier, plasticizer, dyestuff, dispersant and/or surfactant. Yet any these dispensable components must be compatible with Tecastemizole (a kind of secondary amine) in order to guarantee the stability of preparation.
Preferably, the lactose-free formulation according to the Tecastemizole of the present invention preparation comprises Tecastemizole and at least a non-lactose excipient. The example of this excipient is well known in the art and lists among USP (XXI)/NF (XVI), is incorporated herein its full content for reference. More preferably, that comprise Tecastemizole, pharmaceutically compatible according to the lactose-free formulation of Tecastemizole of the present invention preparation and pharmaceutically adhesive/filler and the lubricant of Sq. More preferably, the formulation according to the lactose-free Tecastemizole of the present invention preparation comprises Tecastemizole, microcrystalline cellulose, pregelatinized starch and dolomol.
Also have been found that when using in the composition that is containing the Tecastemizole preparation, other sugar, the degraded that causes similarly, caused by lactose such as fructose and sucrose, although not as above-described effect serious. Therefore, in another embodiment, the pharmaceutical composition that does not conform to lactose comprises Tecastemizole or its officinal salt and the pharmaceutically acceptable excipient of at least a non-lactose, and does not contain any monose or disaccharides excipient, includes, but are not limited to glucose, sucrose and fructose.
As mentioned above, lactinated Tecastemizole preparation runs into unbound water, and for example when moisture and moisture, it is faster to degrade. Simulate long term storage in order to measure the preparation characteristic such as the method for storage period or stability and time relationship as a kind of, pharmaceutical field adopts the method (for example adding 5% water) that adds water widely. See Jens T.Carstensen, Drug Stability:Principles ﹠ Practice, 2d.Ed., Marcel Dekker, NY, NY, 1995, pp.379-80. In fact, water and temperature are all accelerated this research.
And water is quite tangible to the effect of preparation, because help the condition of moisture absorption, for example moisture and/or dampness all may run in production, processing, packing, storage, transportation and the use of preparation usually.Therefore, apparent, owing under ordinary production, packing and storage requirement, in fact exist and the contacting of moisture and/or dampness, should be avoided in the pharmaceutical composition that contains Tecastemizole or the preparation and use lactose.
And, the productivity and the therapeutic that do not influence compositions although the excipient except lactose can easily be used for preparing the lactose-free Tecastemizole pharmaceutical composition of the disclosure, spray-dired lactose remains selected excipient.In spray-dried forms, lactose is mobile best and to be lower than low dosage formulation (for example≤50mg/ agent) be very effective in all direct compression filleies, and in said preparation, main effect is not brought into play in the compatibility of active component.For example, see R.Shangraw, Selection of ManufacturingProcess and Excipients with an Emphasis on Direct Compression, Course material from Granulation, Tableting, and CapsuleTechnology, Center for Professional Advancement, EastBrunswick, NJ, 1996.Therefore, if possible, in the solid dosage forms or the effective excipient of pharmaceutical composition of Tecastemizole, comprise lactose.
Therefore, in addition, the present invention comprises thermodynamics and chemically stable pharmaceutical composition, solid pharmaceutical preparation particularly, it comprises Tecastemizole or its officinal salt and one or more pharmaceutically acceptable excipient of not essential ground, includes, but are not limited to lactose, it is anhydrous wherein containing the lactose preparation, promptly is substantially free of unbound water.
The present invention further comprises thermodynamics and chemically stable non-hygroscopic pharmaceutical composition, and it comprises Tecastemizole or its officinal salt and one or more excipient or component, includes, but are not limited to lactose.Although be not subjected to the restriction of any theory, but these stable anhydrous or non-hygroscopic pharmaceutical composition parts are based on applicant's discovery, promptly when described preparation runs into unbound water, promote and/or may cause incompatible between Tecastemizole and lactose or other monosaccharide or the disaccharide.Therefore, prepare the pharmaceutical composition that is substantially free of unbound water will stop the Tecastemizole that takes place when using reactive excipient and having unbound water accelerated degradation.
Therefore, if lactose is a kind of excipient of needs, so, the present invention relates to non-hygroscopic or anhydrous pharmaceutical composition on the other hand, it comprises Tecastemizole, lactose and not essential ground one or more other excipient or components, and wherein resulting pharmaceutical composition does not conform to unbound water basically.Should be realized that, can prepare non-hygroscopic or anhydrous formulation by standard method, preceding topic condition is to select suitable excipient to make resulting pharmaceutical composition be substantially free of unbound water, and uses the low humidity condition to be prepared.
Should prepare and store the anhydrous Tecastemizole pharmaceutical composition for preparing according to the inventive method so that keep no aqueous.Therefore, with using the pharmaceutical composition that prevents well known in the art to meet the material of water moisture absorption and pack these pharmaceutical compositions, they are packaged in the suitable Medicine box (formulary kits).This packing includes, but are not limited to by the aluminium foil of encapsulating method sealing, plastics etc., unit-dose container, blister or bar packing.
Therefore, second aspect present invention comprises that preparation comprises the method for the solid pharmaceutical preparation of Tecastemizole and lactose, this method is included under anhydrous or low moisture and/or the dampness condition mixes Tecastemizole or its officinal salt and lactose, and wherein said component is substantially free of unbound water.This method can further comprise or not be contained in the described anhydrous or nonhygroscopic solid Tecastemizole preparation of packing under the low humidity condition.By using such condition, the danger that contacts with water reduces and prevents and in fact reduce the degraded of Tecastemizole in processing and storage process.In addition, the product of final packaging have seldom or do not contain unbound water, in fact this improved stability and prevented degraded.Said composition can provide packages sealed, well known to a person skilled in the art vacuum-packed and does not contain in the container of moisture as bottle, sealing deck, blister and other.
According to traditional method, when pharmaceutical compositions or preparation, active component or therapeutic agent (for example Tecastemizole) are milled and/or sieved so that reduce granularity and/or dwindle particle size distribution.Usually, doing like this is optimization such as dissolution, uniformity of dosage units, bioavailability for the various physicochemical properties that make preparation such as active component.Dissolution and Tecastemizole have special relation because when PH 3-4, dissolubility relatively low (approximately 10mg/ml) and when PH4 is above dissolubility lower.Although be not bound by any particular theory, the applicant be sure of that Tecastemizole and reactive excipient can be subjected to the influence of Tecastemizole granule surface area in pharmaceutical composition or the preparation as the interaction between the lactose.

For convenience, employed some term of this paper is defined as follows.Term used herein " carrier " is the synonym of " excipient ".Term used herein " does not contain lactose " and means if present, the quantity not sufficient of lactose is to cause Tecastemizole that the inventor finds and the incompatibility between the lactose in the Tecastemizole dosage form, surpass this dosage form storage life, the adverse effect that Tecastemizole is renderd a service is lower than 90% of initial effectiveness.Term used herein " unbound water " means the water that does not have one or more pharmaceutical composition stable components hydrate forms, as the alpha lactose monohydrate.Similarly, term used herein " anhydrous " means the quantity not sufficient of the unbound water that has (if any) in the Tecastemizole dosage form to cause and/or to promote the incompatibility between Tecastemizole and the lactose.And " anhydrous " used herein, " anhydrous condition " or " anhydrous characteristic " mean and are substantially free of unbound water and comprise moisture.It is non-moisture absorption basically that term used herein " non-hygroscopic " means whole preparation, and the unbound water that is enough to cause and/or promote the incompatibility between Tecastemizole and the reactive excipient (as lactose) promptly is not provided.Term " additive " is a synonym with term used herein " excipient ".Term " is substantially free of " to mean and is lower than about 5% weight, preferably is lower than about 1% weight, more preferably less than about 0.1% weight.Term used herein " bulky grain " means the Tecastemizole compositions and comprises about 40% weight or have 200 μ m or bigger more, is preferably greater than the Tecastemizole of about 250 μ m sizes or the granule of its officinal salt.Term used herein " coating ", " the inertia coating " or " carrying out the inertia coating " mean and use the inertia coating materials to wrap up the Tecastemizole granule and suppress granule and the interaction of reactive excipient (as lactose).Be applicable to that also the present invention does not contain lactose, non-hygroscopic, anhydrous and bulky grain preparation use although be applicable to the non-inertia coating that conventional medicine uses, preferably employed any coating material all is inert and suppresses the interaction of Tecastemizole and any reactive excipient.
Term used herein " pharmaceutically acceptable " refers to be suitable in correct medical diagnosis scope to give and is used for contacting with body fluid with the tissue of humans and animals and does not have over-drastic toxicity, zest, anaphylaxis or other problem or complication, has those chemical compounds, material, compositions and/or the dosage form of rational medicine Sexual health beneficial effect/dangerous ratio.
In addition, use term " pharmaceutically acceptable " excipient, meaning between any excipient composition of Tecastemizole (or its salt) and generation dosage form does not have disadvantageous chemistry or physical incompatibility.For example, disadvantageous chemical reaction is for reducing or increase the effectiveness of Tecastemizole (or its salt) nocuously because of adding one or more excipient.That another example of disadvantageous chemical reaction is that the taste of Tecastemizole (or its salt) dosage form becomes is excessively sweet, acid etc. and make dosage form not good to eat.Excipient with other component compatibility meaning of Tecastemizole preparation on and not injure on the patient must all be " acceptable ".
Physical incompatibility refers to the incompatibility of each composition in the dosage form such as Tecastemizole (or its salt) and any excipient.For example, the combination of excipient and Tecastemizole can form the mixture or the excessive isolated mixture of excessive moisture absorption, therefore can not fully keep the required shape of dosage form (tablet, lozenge etc.), its stability etc., can not be by the relieve pain said preparation of required regulation.
Modally be, by the mode orally give antihistaminic of solid dosage forms (as tablet, capsule, lozenge, caplets etc.), as astemizole or Tecastemizole.In addition, also can use capsule formulation such as hard gelatin capsule, Perle etc.Yet tablet remains preferred dosage form because for patient (as, dosage is accurate, tight, light, taste is gentle and be easy to take medicine) and all be favourable to maker (easy and economic as preparing, stable and packing, transport and distribute conveniently).Tablet is a solid pharmaceutical dosage formulation, contains medicine and is with or without suitable additive.
For with medicine of the present invention or the treatment component (promptly; do not contain lactose, non-hygroscopic, anhydrous, bulky grain or coating Tecastemizole dosage form) be with or without under the diluent condition; make solid dosage forms (as tablet) through spendable equipment pressurization, need have the crystallization of various physical characteristics or the material of powder type.These characteristics for example comprise as powder and are easy to free-pouring ability so that punching press is bonding, and are easy to take out in the slave unit.Because most of materials do not have or these characteristics slightly, the preparation of tablet and preparation method are developed into gives these Ideal Characteristics and these materials is pressed into tablet or similar dosage form.
Should be noted that tablet and similar dosage form can contain the various materials that are called additive except medicine or treatment component.These additives can be classified according to its effect in preparing dosage form such as tablet, caplet, capsule, lozenge etc.One group of additive comprises but is not limited to binding agent, diluent (filler), disintegrating agent and lubricant.
Although that hereinafter discusses variously is used for additive of the present invention and is specifically related to lactose-free dosage form, the further classification that it will be readily appreciated by those skilled in the art that each class all comprises the additive that is applicable to non-hygroscopic of the present invention, anhydrous, bulky grain or coated drugs compositions.In addition, non-hygroscopic of the present invention, anhydrous, bulky grain or coated drugs compositions also can comprise lactose or other list or the disaccharide as excipient.In another embodiment, inorganic bisulfites can be used for improving the stability of any Tecastemizole compositions of this paper.
For the non-hygroscopic preparation, to note selecting excipient and additive especially, under the situation that lacks proper environment control, there is not the tendency of moisture absorption so on the whole.For example, the excipient that is used for said preparation includes but not limited to alpha lactose monohydrate, mannitol etc.
For anhydrous formulation, should use the excipient described below or the additive of suitable anhydrous or low moisture form, for example, AVICEL-PH-103 TMWith Starch 1500 LM.
The use binding agent makes the mixture of tablet ingredients form free-pouring powder and material is flowed on pelleter.Binding agent also provides the caking property of Tecastemizole sheet.Binding agent can produce flow field problem very little and make tablet can not keep its integrity.Binding agent can have a negative impact to the release (dissolution rate) of medicine from tablet too much.Therefore, the binding agent that should mix q.s in tablet produces free-pouring tablet ingredients mixture and the dissolution rate of drug component from tablet is not had a negative impact.For low-dose tablets, required good compressibility may be eliminated to a certain degree because of the suitable dilution adjuvant that use is called as compression aids.The amount of employed binding agent depends on the type and the mode of administration of preparation, and those skilled in the art are easy to determine.
Be suitable for the present invention and do not contain lactose; non-hygroscopic; anhydrous; the binding agent that the Tecastemizole preparation of bulky grain or coating uses includes but not limited to corn starch; potato starch or other starch; gelatin; natural or synthetic natural gum such as arabic gum; sodium alginate; alginic acid; other alginate; the powdery tragakanta; guar gum; cellulose and derivant thereof are (as ethyl cellulose; cellulose acetate; carboxymethylcellulose calcium; sodium carboxymethyl cellulose); polyvinylpyrrolidone; methylcellulose; starch,pregelatinized; hydroxypropyl emthylcellulose (as, the 2208th; 2906; No. 2910); microcrystalline Cellulose or its mixture.
The material that the microcrystalline Cellulose of suitable form is for example sold with AVICEL-PH-101, AVICEL-PH-103 and AVICEL-PH-105 (can be available from FMC Corp., American ViscoseDivision, Avicel Sales, Marcus Hook, PA., USA).An example of proper adhesive is microcrystalline Cellulose and the sodium carboxymethyl cellulose mixture of being sold by FMC Corp. as AVICEL RC-581.
Modal heavily is from about 100 milligrams to about 500 milligrams.Therefore, comprise the Tecastemizole dosage form for many effective medicines, filler occupies the major part of tablet.Use filler (as diluent) to obtain powder (in tablet or capsule) volume so that produce tablet, capsule or other the ideal dosage form that to accept size.In general, in the regular dosage form of suitable size, the treatment component is by mixed diluent formation therein.When having binding agent, the bonding of medicine and filler can take place and influence bioavailability.So, should use the filler of capacity to reach required dilution ratio and drug component is not discharged from the dosage form that contains filler and have a negative impact.In addition, should use physics and chemically with the filler of the treatment component compatibility of dosage form.Therefore, should be noted that if do not note eliminating uncombined water, lactose should not be used from preparation Tecastemizole dosage form of the present invention with Tecastemizole one.The yet preferred lactose-free Tecastemizole dosage form of the present invention does not comprise list or disaccharide, as, but be not limited to glucose, sucrose and fructose.The amount of employed filler depends on the type of preparation and the mode of administration, and those of ordinary skills are easy to determine.
