Abstract

The invention discloses a bendroflumethiazide tablet and a preparation method thereof and belongs to the technical field of medicine preparations. The bendroflumethiazide tablet is composed of, by weight, 0.25-0.5 parts of bendroflumethiazide, 2-6 parts of microcrystalline cellulose PH-102, 4-8 parts of lactose, 0.2-0.6 parts of carboxymethyl starch sodium, and 0.02-0.04 parts of magnesium stearate. The preparation method of the bendroflumethiazide tablet includes the steps of: performing air jet pulverization to the bendroflumethiazide; uniformly mixing the bendroflumethiazide, microcrystalline cellulose PH-102 and magnesium stearate to obtain a mixture material; adding the lactose and carboxymethyl starch sodium to the mixture material, and uniformly mixing the materials; and performing dry-method direct tabletting to obtain the bendroflumethiazide tablet. The bendroflumethiazide tablet is more homogenous in content of bendroflumethiazide and is more rapidly to dissolve out in 5 min. The preparation method is simple, wherein the auxiliary materials, except the microcrystalline cellulose PH-102, are free of special pulverization treatment. The preparation method is free of complex preparation devices and is easy to achieve in industrial production.

Description

technical field [0001] The invention relates to the technical field of pharmaceutical preparations, in particular to a bendrofluthiazide tablet and a preparation method thereof. Background technique [0002] Benzoflumethiazide is 3-benzyl-6-trifluoromethyl-7-sulfonylamino-3,4-dihydro-2H-1,2,4-benzothiadiazine-1,1-dioxide thing. [0003] Efficacy and indications: 1. Edema diseases, excrete excess sodium and water in the body, reduce extracellular fluid volume, and eliminate edema. Common ones include congestive heart failure, cirrhotic ascites, nephrotic syndrome, acute and chronic nephritis edema, early chronic renal failure, sodium and water retention caused by adrenal corticosteroid and estrogen therapy. 2. High blood pressure. It can be used alone or in combination with other antihypertensive drugs. Mainly used for the treatment of essential hypertension. 3. Central or nephrogenic diabetes insipidus. 4. Nephrolithiasis. It is mainly used to prevent stones formed by...
