Abstract

The present invention belongs to the technical field of biomedicine, and particularly relates to a lisinopril compound preparation and a preparation method thereof. In the prior art, the blood pressure lowering effect is not good in the application of the existing lisinopril tablet in the diabetes patient with hypertension. Based on the problem in the prior art, the invention provides a lisinopril compound preparation, which comprises, 10-20 parts of lisinopril, 10-20 parts of gliquidone, and 100-500 parts of an auxiliary material. The preparation method comprises: preparing a soft material A from lisinopril and materials, preparing a soft material B from gliquidone and an auxiliary material, taking the same doses of the soft material A and the soft material B, uniformly tableting to form a tablet, placing into a lactose solution with a concentration of 80-90%, soaking for 3-5 h, and drying to obtain the lisinopril compound preparation. According to the present invention, the prepared lisinopril compound preparation can lower the blood glucose concentration, and can provide the good blood pressure lowering effect in the case of the normal blood glucose, and the preparation method is simple, and is suitable for promotion use.

Description

technical field [0001] The invention belongs to the technical field of biomedicine, and in particular relates to a lisinopril compound preparation and a preparation method thereof. Background technique [0002] Lisinopril is a lysine derivative of enalaprilat, which belongs to the third generation of angiotensin-converting enzyme inhibitors, which can inhibit the activity of angiotensin-converting enzymes and reduce the concentration of angiotensin II and aldosterone , Elevate plasma renin activity, lead to peripheral vasodilation and decrease in vascular resistance, thus producing antihypertensive effect. [0003] Lisinopril has an excellent antihypertensive effect and can effectively control blood pressure for 24 hours. The results of dynamic blood tests show that the antihypertensive effect can last for more than 24 hours once a day, and has no adverse effect on the circadian rhythm of heart rate and blood pressure. Lisinopril also has good renal protection, effectively ...
