Embodiment 1

[0048] Example 1 The composition has the effect of lowering blood pressure and blood fat in hypertensive and hyperlipidemia mammals.

[0049] Establishment of animal model of hypertension with hyperlipidemia

[0050] Adopt the big gray rat that the white rat and the house mouse crossbreed (it is easier to induce success than the purebred white rat), 4 months old, feed and take 10% protein yellow powder, 5% lard, 0.5% bile salt, 85% basal feed, Put them into cages in a soundproof room, and the noise stimulation can be issued by an electric bell or a loudspeaker. The sound generator is an audio oscillator connected to a 20W tweeter. The noise stimulation should be changed frequently at 700-1000 cycles / second, and the noise stimulation can be done once every 30 seconds, or every 1 minute for 30 seconds. It can be changed at any time and does not need to be constant, but the noise disturbance must continue day and night for several months. After noise stimulation for 3 consecuti...

Embodiment 2

[0060] Example 2 The therapeutic effect of the composition on mammalian (including human) atherosclerosis.

[0061] Animal model construction of atherosclerosis

[0062] Rabbit induction model: select Japanese white rabbits, weighing about 2kg, fed with 1g of cholesterol per day, aortic atherosclerotic plaques can be seen with the naked eye after 2 months; the incidence of aortic plaques is 100%, and serum cholesterol can grow up to 540mg / dl.

[0063] Grouping: 40 white rabbits with successful modeling were taken and divided into four groups of 10 each: blank control group: no administration; amlodipine administration group: amlodipine 0.28mg / kg administration; niacin administration group: administration of Niacin 110 mg / kg; the composition administration group (containing amlodipine and nicotinic acid): Amlodipine 0.28 mg / kg and nicotinic acid 110 mg / kg were given.

[0064] Administration method: the medicines of each dosage group were ground into fine powder 30 minutes be...

Embodiment 3

[0069] Example 3 The control effect of the composition on cardiac risk in mammals (including humans).

[0070] Grouping: Take 400 model animals (successfully modeled large squirrels) constructed in Example 1 and divide them into four groups, each with 100 animals. Each group continues to be given high-fat feed and continuous noise stimulation. Blank control group: no administration; Amlodipine administration group: give amlodipine 0.5mg / kg; Nicotinic acid administration group: give niacin 200mg / kg; This composition administration group (containing amlodipine and tobacco acid): give amlodipine 0.5mg / kg and niacin 200mg / kg.

[0071] Administration method: the medicines of each dosage group were ground into fine powder 30 minutes before the test in the morning of the same day, and made into a perfusion liquid with 3% starch paste (starch, produced by North China Pharmaceutical Factory), and 30 ml was perfused every day.

[0072] After feeding for 2 years, each group was executed...

Abstract

The invention relates to a pharmaceutical composition of amlodipine or a pharmaceutically acceptable acid additive salt thereof and nicotinic acid, a medical box containing the compositions, and a method of using the compositions to treat patients suffering from angina pectoris, atherosclerosis and accompanied hypertension, and treating patients (including human beings) having heart risk symptoms. The invention also relates to an additive synergic composition of the amlodipine and the nicotinic acid, which can be used for treating the patients suffering from the angina pectoris, the atherosclerosis and the accompanied hypertension and the hyperlipoidemia, and treating the patients (including human beings) having heart risky symptoms.

Description

technical field [0001] The present invention relates to a pharmaceutical composition containing amlodipine or a pharmaceutically acceptable salt thereof and nicotinic acid, a kit containing these compositions, and using these compositions to treat patients with coronary heart disease, atherosclerosis, angina pectoris, combined high Patients with high blood pressure and hyperlipidemia and patients whose main symptoms are heart risk symptoms. Background technique [0002] Hypertension is one of the most common cardiovascular diseases that endanger human health. It is a major public health issue worldwide. A large number of evidence-based medical studies have confirmed that: as blood pressure increases, the risk of cardiovascular disease increases significantly. Blood pressure increases from 115 / Starting from 75mmHg, every increase of 20 / 10mmHg will double the cardiovascular risk, and active treatment can effectively reduce the morbidity and mortality of cardiovascular events,...
