Embodiment 1
[0021] A bromhexine hydrochloride sustained-release capsule, the preparation method comprising the following steps:
[0022] The preparation method comprises the following steps:
[0023] 1) Weigh 10 g of bromhexine hydrochloride and 1 g of sweetener, add 800 ml of purified water, stir and make it dissolve completely;
[0024] 2) Add 0.1 lactose and pregelatinized starch, stir well to dissolve completely;
[0025] 3) The dispersant PEG-4000 is prepared into a 1.0g / 100ml solution, and ethylenediamine is added to adjust the pH to 8.2;
[0026] 4) Add purified water to make the volume to 1000ml;
[0027] 5) After filtering with a 0.22 μm filter membrane, use a CIK2000 nano-disperser to stir and disperse to obtain bromhexine hydrochloride nano-dispersant;
[0028] 6) The bromhexine hydrochloride nano-dispersant is distilled under reduced pressure, and poured into a fluidized bed to prepare bromhexine hydrochloride sustained-release capsules.
