Embodiment 1
[0015] Embodiment 1: metformin hydrochloride rosiglitazone double-layer sustained-release tablet
[0016] prescription:
[0017]
[0018] Preparation:
[0019] Metformin hydrochloride is passed through a 100-mesh sieve, HPMC-15M, HPMC-4M, and microcrystalline cellulose are passed through a 60-mesh sieve, and after the raw and auxiliary materials are mixed evenly, a soft material is made with 80% ethanol solution, granulated with a 20-mesh sieve, dried at 40°C, and dried for 18 Mesh sieve for granulation, and set aside; in addition, rosiglitazone, lactose, calcium hydrogen phosphate, and acrylic resin RS100 were sieved and mixed three times, and the granules were sized in the same way. The above two granules are weighed in proportion respectively, and after adding magnesium stearate, they are compressed into double-layer sustained-release tablets.
