Prescription and preparation process science, reasonable, feasible, applicant in order to ensure febuxostat tablet of the present invention
Series of experimental research and investigation are carried out.
First, formulation study:
1st, bulk pharmaceutical chemicals property
Febuxostat is white or off-white color crystalline powder;It is insoluble in water.Therefore, when drafting the prescription of tablet,
The dissolution rate of medicine is an aspect considered emphatically.
2nd, the property of auxiliary material and selection
It was found from from the relevant information of the ADENURIC of European Union's approval, the auxiliary material used in ADENURIC is lactose, crystallite
Cellulose, magnesium stearate etc..
Lactose compact property is good, and uses lactose unilateral more smooth as filler, and appearance is preferable.
Microcrystalline cellulose has good mobility and compressibility as filler, and water swelling is disintegrated rapidly, after disintegration
Particle is very thin
Ac-Di-Sol has extremely strong disintegration ability.It is especially suitable for the strong medicine of hydrophobicity.
Magnesium stearate is lubricant, is easy to particle mixing, makes unilateral smooth.
3rd, prescription screening
Since Febuxostat is practically insoluble in water, when carrying out prescription screening mainly with disintegration time limited of tablet, molten
Out-degree etc. is main inspection target, the results are shown in Table 1.
1 prescription screening result of table
Supplementary material title | Prescription 1 | Prescription 2 | Prescription 3 | Prescription 4 |
Febuxostat | 4.0g | 4.0g | 4.0g | 4.0g |
Microcrystalline cellulose | 8.1g | 6.8g | 5.5g | 5.5g |
Lactose | ―― | 1.0g | 2.0g | 2.0g |
Ac-Di-Sol | 0.3g (outer) | 0.6g (outer) | 0.9g (outer) | 0.5g (outer) 0.4g (interior) |
Magnesium stearate | 0.1g | 0.1g | 0.1g | 0.1g |
Appearance character | It is unilateral slightly rough | It is unilateral slightly rough | It is unilateral bright and clean | Unilateral bright and clean beauty |
Disintegration time limited (min) | 20 | 14 | 8 | 7 |
Dissolution rate surveys (%) | ---- | ---- | 81.3 | 88.6 |
As a result:Piece weight is designed in four prescriptions in 0.25g, does not add lactose in prescription 1, it is unilateral that some are coarse, and
The disintegration and dissolution of tablet are not ideal;The dosage of lactose and disintegrant is increased in prescription 2, disintegration time and dissolution are
Improve, but it is undesirable;The dosage of disintegrant is increased in prescription 3, increases unilateral bright and clean beauty after lactose dosage, but
The accidental particle not being disintegrated in disintegrating procedue.So by the disintegrant for having half in prescription 4 be changed in plus, disintegration time limited and molten
Go out to meet the requirements, it is ideal.
Conclusion:Tentatively by the prescription of prescription 4 as study on the stability prescription.
2nd, Study of operational conditions

Mixture is pelletized, observing effect, and is screened.It the results are shown in Table 2.
2 adhesive the selection result of table
Note:18 mesh sieve granulating process are used above.
Conclusion:Using 50% ethanol as adhesive, material viscosity is larger, can not pelletize;Using water and 2%PVP-k30
Aqueous solution is as adhesive, and particle is uniform, and completely, good fluidity, tablet weight variation is small, both are without significant difference, from simple process
And economic angle considers, directly using purified water as adhesive.
2nd, the measure of critical relative moisture
For the preparation of solid pharmaceutical preparation, the moisture absorption of drug powder is a ring that must be paid close attention in preparation process
Section.The critical relative moisture of drug powder must be measured, and operating environment is controlled by.
Method:CH is prepared respectively3COOK、MgCl2、KNO3、NaBr、NaCl、KCl、KNO2Saturated solution, by the full of preparation
Be respectively implanted with solution in silica gel drier, in 25 DEG C place 72 it is small when, respectively obtain relative humidity for 20.0%, 33.0%,
42.8%th, 59.7%, 75.3%, 84.3%, 92.5% constant humidity solution.
When by the medicinal mixture prepared, drying 48 is small in phosphorus pentoxide desiccator, in the measuring cup of constant weight
Bottom is put into the mixture of 2g or so, after precision weighing, is placed in the drier for filling 7 kinds of different saturated solutions and keeps 72 small
When, precise weighing, calculates Moisture percentage, the results are shown in Table 3.
The Moisture percentage of medicinal powder under the different relative humidity of table 3
Solution | RH% (25 DEG C) | Moisture percentage (%) |
CH3COOK | 20.0 | 1.98 |
MgCl2 | 33.0 | 2.22 |
KNO3 | 42.8 | 2.44 |
NaBr | 59.7 | 3.82 |
