Embodiment 1
[0036] Example 1 Matrix-type sustained-release tablet
[0037] Febuxostat 80mg
[0038] Hypromellose (K15M) 15mg
[0039] Hypromellose (K4M) 15mg
[0040] Lactose 85mg
[0041] 5% Povidone K30 in 75% ethanol 60mg
[0043] (The 75% ethanol solution of 5% povidone K30 refers to the 75% ethanol solution containing 5% povidone K30 by mass);
[0044] Preparation
[0045] After crushing febuxostat, pass it through a 100-mesh sieve, and then mix it with hypromellose (K15M), hypromellose (K4M) and lactose, then add 5% povidone K30 in 75% ethanol solution , use HLSH2-6 wet mixing granulator to prepare soft materials, sieve wet granules with 24 mesh, dry the wet granules by blasting at 50 ℃ ~ 60 ℃, dry granules with a 22 mesh sieve, add magnesium stearate and mix After uniformity, use ZP10A tablet press for tableting.
Embodiment 2
[0046] Example 2 Coated sustained and controlled release tablet
[0047] Chip formula
[0048] Febuxostat 80mg
[0049] Calcium hydrogen phosphate 25mg
[0050] Microcrystalline Cellulose 110mg
[0051] 2% Hypromellose K15M in water 40mg
[0053] coating material
[0054] 15% ethyl cellulose dispersion in water 116mg
[0055] Preparation Process
[0056] After crushing febuxostat, pass it through a 100-mesh sieve, and then mix it with calcium hydrogen phosphate and microcrystalline cellulose evenly, add 2% hypromellose K15M aqueous solution, and use HLSH2-6 type wet mixing granulator to prepare Soft material, 24 mesh sieve to make wet granules, the wet granules are air-dried at 50 ℃ ~ 60 ℃, the dry granules are granulated with a 22 mesh sieve, after adding magnesium stearate and mixing evenly, use a ZP10A tablet machine for tableting, hardness Range 35-85N, and then coat with 15% aqueous ethyl cellulose dispersion.
Embodiment 3
[0057] Embodiment 3 skeleton type slow-release capsule
[0058] Febuxostat 80mg
[0059] Hypromellose (K15M) 15mg
[0060] Hypromellose (K4M) 15mg
[0061] Microcrystalline Cellulose 85mg
[0062] 5% Povidone K30 in 75% ethanol 60mg
[0063] Micronized silica gel 2mg
[0064] Preparation
[0065] After crushing febuxostat, pass it through a 100-mesh sieve, and then mix it with hypromellose (K15M), hypromellose (K4M), and microcrystalline cellulose, and then add 75% of 5% povidone K30. % ethanol solution, use HLSH2-6 wet mixing granulator to prepare soft material, and then add JBZ-300 multifunctional granulation coating machine to extrude and spheronize to prepare pellets. The pellets are prepared at 50℃~60℃ Blast dry, add micropowder silica gel and mix evenly, then fill into No. 0 capsule shell.
