Embodiment 1
[0034] Example 1: Preparation of dronedarone hydrochloride sustained-release tablets
[0035] Weigh 1g dronedarone hydrochloride, 2.5g glyceryl palmitate stearate, 5g microcrystalline cellulose, mix them evenly according to the same volume addition method, pass through an 80 mesh sieve, 2.5g waxy melt (0.5g white beeswax , 1g palm wax and 1g PEG6000 plus ethanol are melted at 85°C and then dried to remove ethanol) Add the main drug, microcrystalline cellulose and stearic acid palmitate to the mixture of PVPK30 ethanol solution (concentration is 5%wt.) Used as a binder (10g of solution) to make soft materials, granulate on a 30-mesh sieve, dry at 60°C for 1 hour, and then size the 30-mesh sieve, add 0.2g of magnesium stearate and 0.3g of silicon dioxide, mix well, and press .
Embodiment 2
[0036] Example 2: Preparation of dronedarone hydrochloride sustained-release tablets
[0037] Weigh 1.2g dronedarone hydrochloride, 5g glyceryl palmitate stearate, and 2.5g microcrystalline cellulose, mix them evenly according to the same volume addition method, pass through an 80 mesh sieve, 2.5g waxy melt (0.5g white Beeswax, 1g palm wax and 1g PEG6000 plus ethanol are melted at 85°C and dried to remove ethanol) are added to the mixture of the main drug, microcrystalline cellulose and glyceryl palmitate stearate, and the ethanol solution of PVPK30 (concentration of 5% wt. ) Used as a binder (10g of solution) to make soft materials, granulate with 30 mesh sieve, dry at 60°C for 1 hour, and after granulation on 30 mesh sieve, add 0.2g magnesium stearate and 0.3g silicon dioxide, mix and press sheet.
Embodiment 3
[0038] Example 3: Preparation of dronedarone hydrochloride sustained-release tablets
[0039] Weigh 1.5g dronedarone hydrochloride, 0.5g glyceryl monostearate, 2.5g microcrystalline cellulose, mix them evenly according to the same volume addition method, pass through an 80 mesh sieve, 2g waxy molten liquid (1.5g white beeswax And 0.5g of PEG2000 and ethanol are melted at 85°C and dried to remove the ethanol) is added to the mixture of the main drug, microcrystalline cellulose and glyceryl palmitate stearate, and the ethanol solution of PVPK30 (concentration of 2%wt.) is used as the adhesive (10g of solution amount) to make soft material, granulate with 30 mesh sieve, dry at 60°C for 1 hour, after granulation on 30 mesh sieve, add 0.1g magnesium stearate, mix well, and compress.
