Abstract

The invention discloses a medicine composite for treating and relieving high blood pressure and a preparation method thereof. The composite comprises 10-320mg of telmisartan and 1-20mg of felodipine slow-release preparation. The composite is used for treating patients with moderate and acute high blood pressure and patients whose blood pressure can not be adequately controlled after the high blood pressure is treated by an angiotensin II receptor antagonist or a calcium antagonist.

Description

technical field [0001] The invention relates to a pharmaceutical composition and a preparation method thereof for treating patients with moderate or high blood pressure and hypertension whose blood pressure cannot be fully controlled after treatment with angiotensin II receptor antagonists or calcium antagonists, specifically Pharmaceutical composition and use made with telmisartan and felodipine. Background technique [0002] Telmisartan, a white to pale yellow solid, is an angiotensin II receptor antagonist developed for the treatment of hypertension and other medical indications as disclosed in EP-A-502314. It is a non-peptide molecule, and its chemical name is: 4'-[(1,4'-dimethyl-2'-propyl-[2,6'-bi-1H-benzimidazole]-1'-yl) Methyl]-[1,1'-biphenyl]-2-carboxylic acid, its molecular formula is: C 33 h 30 N 4 o 2 , its molecular weight is: 514.63, and its structural formula is: [0003] [0004] Telmisartan is prepared and supplied in the free acid form. It is chara...
