Problems solved by technology

[0004] To sum up, although there have been many reports on the combined application of irbesartan and hydrochlorothiazide to have a synergistic antihypertensive effect, all the reports are on the combined application of irbesartan and low-dose hydrochlorothiazide, and there is no report on the combination of irbesartan and hydrochlorothiazide. The use of low-dose irbesartan has been reported, and there is no literature report that hydrochlorothiazide combined with low-dose irbesartan can be used to reduce the risk of elevated serum C-reactive protein (CRP) in hypertensive patients

Abstract

The invention discloses a drug composition containing irbesartan and hydrochlorothiazide. The drug composition is prepared into a tablet or a capsule by wet granulation of an active ingredient and a pharmaceutic adjuvant; the active ingredient comprises irbesartan and hydrochlorothiazide at a weight ratio of 1:(1.3-10); and the pharmaceutic adjuvant comprises a filler, a disintegrating agent, adhesive and a lubricant. With the adoption of the drug composition, impaired glucose tolerance is alleviated, the biological activity of insulin resistance is prevented, rising of a C-reactive protein level of a patient with hypertension can be prevented, the morbidity and mortality of and caused by various cardiovascular diseases in the future are reduced, and the drug composition has a very good improvement effect on the prognoses of the patient with the hypertension.

Description

technical field [0001] The invention belongs to the technical field of pharmaceutical preparations, in particular to a pharmaceutical composition containing irbesartan and hydrochlorothiazide. Background technique [0002] The occurrence of hypertension is caused by various factors such as hyperactivity of the sympathetic nervous system, renal water and sodium retention, and activation of the renin-angiotensin-aldosterone system (RAAS), and the existing antihypertensive drugs can only target a certain pathogenesis The mechanism works, and the antihypertensive effective rate of any antihypertensive drug is only 25%-50%. In order to effectively control blood pressure, 70% of hypertensive patients need to use antihypertensive drugs in combination. The 2007 European Society of Hypertension (ESH) / European Society of Cardiology (ESC) hypertension guidelines pointed out that the initial blood pressure is grade 2 or 3 hypertension, and patients with normal blood pressure but high or...
