Problems solved by technology

At present, the medical community and patients are mainly concerned about three issues about high blood pressure drugs: first, whether the antihypertensive effect is mild and stable, and whether it can protect other organs from damage; Whether the quality is not affected or the impact is very small; Third, as a chronic common disease, hypertension requires long-term control by patients, and whether the resulting costs are too expensive, which requires that the drug itself should be economical, so that the treatment of patients and the society is equal. able to bear
However, quercetin has poor water solubility and low bioavailability when used directly as a drug

[0050] formula:

[0051] Quercetin 20mg

[0052] Pinoresinol Diglucoside 20mg

[0053] PVP-k30 60mg

[0054] Preparation Process:

[0055] Take 20 mg of quercetin and 20 mg of pinoresinol diglucoside in a mixer and mix them evenly, add 60 mg of PVP-k30 to the reaction flask, add an appropriate amount of 95% ethanol, and stir in a water bath at 50°C for 3 hours until the solution is clear, then vacuum The solvent was removed by evaporation, freeze-dried, pulverized into powder, and sieved with 80 meshes to obtain a PVP dispersion of quercetin-pinoresinol diglucoside, which was stored in a desiccator for later use.

Abstract

The invention relates to novel medical anti-hypertension compound slow release tablets. The tablets are mainly prepared from four bioactive components of 5 mg-20 mg of quercetin, 5 mg-20 mg of pinoresinol diglucoside (effective ingredient of the bark of eucommia), 0.4 mg-1.60 mg of sulfonamide diuretic indapamide and 2 mg-10 mg of angiotensin reductase II inhibitor (ACEI) perindopril salt and pharmaceutical adjuvants of 20 mg-60 mg of PVP-k30, 10 mg-30 mg of hydroxyl propyl cellulose (HPMC-K15M), 30 mg-60 mg of lactose, 53 mg-80 mg of microcrystalline cellulose (MCC), 1 mg-2 mg of magnesium stearate (lubricating agent), 2 mg-4 mg of low hydroxypropyl cellulose (LHPC, disintegrating agent), 1 mg-20 mg of starch and 1 mg-10 mg of talcum powder. The novel anti-hypertension compound slow release tablets provide a safe and effective medicine help for adjusting and stabilizing blood pressure of patients, improving heart functions, relieving heart and cerebral vessel lesions and avoiding occurrence of other cardiovascular disease risks.
