Abstract

The invention discloses a compound antihypertensive drug combination preparation containing furosemide and spironolactone and a preparation method thereof. Wherein, the compound antihypertensive drug combination preparation includes a tablet core and a coating, and the tablet core includes the following components based on the total weight of the core in the photo: 10% to 40% of furosemide, 20% to 50% of spironolactone, and 2% of solubilizer ~4%, filler 10%~60%, disintegrant 4%~8%, lubricant 0.5%~1% and binder 0.1%~2%.

Description

technical field [0001] The invention relates to the technical field of pharmaceutical preparations, in particular to a compound antihypertensive drug combination preparation containing furosemide and spironolactone and a preparation method thereof. Background technique [0002] Furosemide, white or off-white crystalline powder; soluble in acetone, slightly soluble in ethanol, insoluble in water; belongs to strong diuretic, is a high-efficiency diuretic acting on the ascending branch of Heinz loop. It is clinically used to treat edema disease, liver cirrhosis, hypertension, congestive heart failure, hyperkalemia and hypercalcemia, dilutional hyponatremia, hypersecretion of antidiuretic hormone and acute drug poisoning, etc. , can prevent acute renal failure and the clinical situation where diuretics are not effective and diuretics are urgently needed. But the disadvantage is that it can cause blood electrolyte disturbance, especially for K + The impact is obvious. [0003]...
