Abstract

The invention belongs to the technical field of medicines, and particularly relates to a pharmaceutical composition containing lisinopril and amlodipine besylate and a preparation method of the pharmaceutical composition. The pharmaceutical composition comprises the following components in parts by weight: 10 parts of lisinopril, 5 parts of amlodipine besylate (based on the weight of amlodipine), 100-200 parts of microcrystalline cellulose, 6-10 parts of sodium carboxymethyl starch, 1-3 parts of fumed silica and 2-4 parts of magnesium stearate. The pharmaceutical composition is prepared by using a dry granulating tableting process. The pharmaceutical composition has reasonable formula and good stability. The preparation method is simple in process and high in production efficiency; the preparation process of the pharmaceutical composition does not cause the increase of impurity content; the content uniformity of the prepared pharmaceutical composition is good.

Description

technical field [0001] The invention belongs to the technical field of medicine, and relates to a pharmaceutical composition containing lisinopril and amlodipine besylate and a preparation method thereof. Background technique [0002] Hypertension is the most important risk factor leading to the occurrence and death of heart disease, cerebrovascular disease, and kidney disease. The purpose of antihypertensive drug therapy for hypertensive patients is to effectively prevent or delay stroke, myocardial infarction, The occurrence of cardiovascular and cerebrovascular complications such as heart failure and renal insufficiency can effectively control the disease process of hypertension and prevent the occurrence of severe hypertension such as hypertensive emergencies and sub-emergencies. [0003] Commonly used antihypertensive drugs include calcium channel blockers (CCBs), angiotensin-converting enzyme inhibitors (ACEIs), angiotensin receptor blockers (ARBs), diuretics, and β-bl...
