Problems solved by technology

[0007] When using benidipine hydrochloride or benazepril hydrochloride clinically now, there are often the following problems: 1. When using a single drug, the dosage of the drug must be increased to ensure the curative effect, which will inevitably lead to a significant increase in side effects of the drug; 2. When taking medication, because there is no pharmaceutical preparation that meets the dosage of the combined medication, the dosage used for clinical use is inaccurate, which affects the efficacy of the medication

Abstract

The invention discloses a compound preparation containing benidipine hydrochloride and benazepril hydrochloride, as well as application thereof, wherein preparation containing benidipine hydrochloride and benazepril hydrochloride serve as effective components of the medicament. According to the compound preparation, the defects of large dose and high side effect of single drug are overcome, and the compound preparation disclosed by the invention is obtained by compounding the benidipine hydrochloride and benazepril hydrochloride. Oral preparations with different forms can be prepared by the preparation, due to synergic and complementary effects of medicaments, the compound preparation has reinforced treatment effect, the medicament dose is reduced in clinical application, adverse reaction of a patient is lightened, and the compound preparation can be accepted easily. The compound preparation has remarkable treatment effect in mild and severe hypertension, and is suitable for hypertension patient with cardiovascular remodeling, and patients with renal hypertension, hypertension with renal damage or with diabetic renal damage. Furthermore, the compound preparation has low price, simple preparation and easy popularization and application.

Description

technical field [0001] The invention relates to a compound preparation and an application thereof, in particular to a compound preparation containing benidipine hydrochloride and benazepril hydrochloride and an application thereof, belonging to the technical field of biomedicine. Background technique [0002] Hypertension is the most prevalent disease in the world today, known as the "silent killer". According to the global burden of disease survey in 2000, 50% of cardiovascular diseases are caused by high blood pressure, which accounts for 4.5% of the current global disease burden. High blood pressure is common in both developed and developing countries. At present, about 25% to 35% of adults in the world are hypertensive patients, and the total number of hypertensive patients reaches 972 million; while the number of people over 70 years old rises to 60% to 70%. Among the causes of death of people over 40 years old in my country, heart disease and cerebrovascular disease r...
