Embodiment 1
[0030] Enteric-coated sustained-release tablets
[0031] prescription:
[0032]
[0033] Preparation Process:
[0034] Pass glipizide, hydroxypropyl methylcellulose, starch, lactose, and magnesium stearate through 80-mesh sieve respectively for later use, weigh hydroxypropyl methylcellulose, starch, and lactose according to the prescription and put them in a mixer After mixing, mix with glipizide in equal increments, add an appropriate amount of 70% ethanol, granulate, dry at 45°C for 30 minutes, add the prescribed amount of magnesium stearate to the dry granules, mix them evenly, and pass through a swinging granulator for 16 Mesh sieve granules, carry out content determination on the granules, and determine the tablet weight range, tableting to obtain sustained-release tablets, use 85% ethanol to prepare coating powder containing enteric-coated material cellulose acetate phthalate to prepare enteric-coating solution , and then wrap the enteric coating on the obtained sus...

[0037] Enteric-coated sustained-release tablets
[0038] Prescription: plain tablet
[0039]
[0040] Prescription: Sustained-release coating solution
[0041] 25 parts of hydroxypropyl methylcellulose
[0042] 10 parts ethyl cellulose
[0043] Propylene glycol 5 parts
[0044] Tween 80 1.5 parts
[0045] Titanium dioxide 6 parts
[0046] 4 parts talcum powder
[0047] 2% ethyl cellulose ethanol solution appropriate amount
[0048] Preparation Process:
[0049] Pass glipizide, polyvinylpyrrolidone, starch, microcrystalline cellulose, and magnesium stearate through an 80-mesh sieve respectively, weigh polyvinylpyrrolidone, starch, and microcrystalline cellulose according to the prescription amount, and put them in a mixer to mix them evenly Then mix with glipizide in equal increments, add an appropriate amount of 80% ethanol, granulate, dry at 45°C for 30 minutes, add prescription amount of magnesium stearate to the dry granules, and pass through a 16-mesh sieve with...
Embodiment 3
[0052] Enteric-coated sustained-release capsules
[0053] prescription:
[0054]
[0055] Preparation Process:
[0056] Pass glipizide, hydroxypropyl methylcellulose, ethyl cellulose, microcrystalline cellulose, xylose, and magnesium stearate through 80 mesh sieves respectively, and weigh hydroxypropyl methylcellulose, Ethyl cellulose, microcrystalline cellulose, xylose, and magnesium stearate are mixed in a mixer and then mixed with glipizide in equal increments, and 4% polyvinylpyrrolidone ethanol solution is used to make soft materials. Granulate in a granulator. The granules prepared above were dried at 60° C. for 1.5 h. Then pass through a swinging granulator, and use a 20-mesh sieve to sieve the granules. The content of the mixed granules is determined, and the capacity range of the enteric-coated capsule shell is determined to be filled, and then packed after passing the inspection.
[0057] The glipizide enteric-coated sustained-release capsules prepared by the...
