Embodiment 1
[0031] A kind of berberine hydrochloride oryzanol tablet, its composition is as follows:
[0032]
[0033] Preparation:
[0034] (1) Preparation of berberine hydrochloride oryzanol granules
[0035] Mix berberine hydrochloride, oryzanol, polysorbate 80, and hypromellose, jet mill, and dry granulate. The added polysorbate 80 and the added hypromellose were dissolved in 3% hydroxyethyl cellulose aqueous solution to obtain a coating solution. The above-mentioned coating liquid is sprayed onto the granules obtained by dry granulation by means of fluidized bed spraying, and the weight gain of the coating is 3%, to obtain the berberine hydrochloride oryzanol modified granules.
[0036] (2) Preparation of tablets
[0037] The above-mentioned berberine hydrochloride oryzanol modified granules are mixed with lactose, croscarmellose sodium and magnesium stearate and then compressed into tablets.
Embodiment 2
[0039] A kind of berberine hydrochloride oryzanol tablet, its composition is as follows:
[0040]
[0041] Preparation:
[0042] (1) Preparation of berberine hydrochloride oryzanol granules
[0043] Mix berberine hydrochloride, oryzanol, sodium lauryl sulfate, and poloxamer, jet mill, and dry granulate. Added sodium lauryl sulfate and added poloxamer were dissolved in 5% aqueous solution of hydroxyethyl methylcellulose to obtain a coating solution. The above-mentioned coating liquid is sprayed onto the granules obtained by dry granulation by means of fluidized bed spraying, and the weight gain of the coating is 3%, to obtain the berberine hydrochloride oryzanol modified granules.
[0044] (2) Preparation of tablets
[0045] The above-mentioned berberine hydrochloride oryzanol modified granules are mixed with lactose, croscarmellose sodium and magnesium stearate and then compressed into tablets.
Embodiment 3
[0047] A kind of berberine hydrochloride oryzanol tablet, its composition is as follows:
[0048]
[0049] Preparation:
[0050] (1) Preparation of berberine hydrochloride oryzanol granules
[0051] Mix berberine hydrochloride, oryzanol, sodium lauryl sulfate, and hypromellose, jet mill, and dry granulate. The added sodium lauryl sulfate and the added hypromellose were dissolved in a 3% aqueous solution of hydroxyethyl methylcellulose to obtain a coating solution. The above-mentioned coating liquid is sprayed onto the granules obtained by dry granulation by means of fluidized bed spraying, and the weight gain of the coating is 3%, to obtain the berberine hydrochloride oryzanol modified granules.
[0052] (2) Preparation of tablets
[0053] The above-mentioned berberine hydrochloride oryzanol modified granules are mixed with microcrystalline cellulose, lactose, crospovidone and magnesium stearate, and then compressed into tablets.
