Description

technical field [0001] The invention belongs to the technical field of medicines, in particular to a tablet containing manidipine hydrochloride and azilsartan and a preparation method thereof. Background technique [0002] Hypertension is a syndrome with elevated blood pressure as the main clinical manifestation. It is the most common cardiovascular disease and the most important risk factor leading to liver disease, cerebrovascular disease, kidney disease and death. Since hypertension is a multifactorial disease involving the combined effects of genetic and environmental factors, the renin vasodilator-aldosterone system, sympathetic nervous system, body fluid volume system, and cell particle transport system are involved in its occurrence and development. The efficacy of single antihypertensive drugs is often not good, especially for patients with moderate and severe hypertension, antihypertensive drugs should be combined for treatment. [0003] Currently commonly used ant...
