Possible pharmaceutical preparation methods

The dihydroquercetin powder produced by Kintai can be used in a variety of pharmaceutical methods, including oral solid dispersion preparations. The following is an example of a specific preparation method:
DHQ Dihydroquercetin oral solid dispersion preparation:
1.Preparation of dihydroquercetin solid dispersion:
Weigh 200g of dihydroquercetin powder, crush it and pass it through a 100-mesh sieve to ensure uniform particle size.
Take 1 liter of anhydrous ethanol to dissolve dihydroquercetin and ensure full dissolution.
Then weigh 1200g of polyvinyl pyrrolidone (PVP-k30), crush it and pass it through a 100-mesh sieve, add it to the dihydroquercetin ethanol solution, and stir until it is completely dissolved.
2.Evaporation of solvent and drying:
Place the solution in a 55°C water bath for rotary evaporation and recover the ethanol to a dry state.
Take out the dried dihydroquercetin solid dispersion and put it into a dryer for 24 hours.
After balancing, crush it and pass it through a 100-mesh sieve to obtain a uniform dihydroquercetin solid dispersion.
3.Tabletting:
Weigh 300g of lactose and 300g of microcrystalline cellulose, add them to the dihydroquercetin solid dispersion respectively, and mix them thoroughly.
Add 20g of magnesium stearate as a lubricant, mix evenly, and directly tablet the whole powder to obtain the finished dihydroquercetin tablets.
This preparation process can not only ensure the efficacy of the drug, but also enhance the absorption effect of dihydroquercetin in the body, so that it can better exert multiple effects such as antioxidant, anti-tumor, and anti-inflammatory.
