Problems solved by technology

[0010] The ACE inhibitor enalapril was first developed by Merck in the United States, and it was launched in the Federal Republic of Germany in 1984. It was once one of the best-selling prescription drugs in the European and American markets, but sales began to decline after 2001. The main reasons are: enalapril The patent expired in 2000, and countries imitated it one after another; new products of the same kind appeared continuously; there were some problems in itself: (1) the antihypertensive curative effect had a certain limit, and a large number of literature reports had a total effective rate of only about 60%, and 40% were ineffective or had no curative effect. Significantly; (2) Target
The 3-year epidemiological monitoring showed that nearly 30% of the patients who insisted on taking benazepril still did not reach the target, and the elderly patients showed poor performance, which may be related to the higher baseline systolic blood pressure level of the elderly patients In addition, on the whole, the control of systolic blood pressure is more difficult than diastolic blood pressure (Lv Jun. Chinese Journal of Epidemiology, 2004; 25(5): 412~6)
[0028] Patent and scientific literature searches did not find any reports on the combined application of enalapril / benazepril and sotalol

The present invention relates to a medicine composition containing enalapril or benazepril and sotalol. It is a new type hypotensor medicine composition. The content of enalapril or benazepril is 5-40 mg and the sotalol content is 20-160mg.

Description

technical field [0001] The invention relates to a novel pharmaceutical composition, in particular to a chemical pharmaceutical composition containing enalapril or benazepril and sotalol and its application in preparing medicine. belongs to the field of pharmacy. Background technique [0002] Enalapril (Enalapril) was first developed by Merck Company of the United States and was listed in the Federal Republic of Germany in 1984. It is an angiotensin-converting enzyme (ACE) inhibitor. After oral administration, it is hydrolyzed into Enalaprilat in the body. The latter strongly inhibits ACE, reduces the content of angiotensin II, causes systemic vasodilation, and lowers blood pressure. It has obvious antihypertensive effect on two-kidney-one-clip hypertensive rats, one-kidney-one-clip hypertensive rats and spontaneously hypertensive rats. For the treatment of essential hypertension. [0003] Benazepril (Benazepril, Benazepril, Luotingxin) was researched and developed by Nova...
