A kind ofly treat the compound preparation that hypertension contains trandolapril
Technical field:
The present invention relates to a kind of compound preparation that hypertension contains trandolapril for the treatment of, belong to drug world.
Background technology:
Along with China's rapid growth of economy, the drastic change of people life style, the acceleration of urbanization, aging, the cardiovascular diseases has become first or second cause of the death of rural and urban population.Especially patients with hypertension, its sickness rate accounts for total population about 15%.Morbidity colony is so big, seeks medicine evident in efficacy, that side effect is little and seems more important.
The hypertensive medicine of treatment has multiple at present, such as calcium antagonist (CCBs), converting enzyme inhibitor (ACEI), Angiotensin (ARBs) etc., but single medicine treatment hypertension is difficult up to standard in a short time, and Most patients need be taken two or more antihypertensive drug can reach the blood pressure lowering target.Especially blood pressure exceeds desired value 20/10mmHg, and beginning need be taken two kinds of medicines often.Single medicine is prone to drug resistance, and because the bigger probability that toxicity occurs of dosage is also bigger.Majority is to give two or more drug administration treatments simultaneously.But several drugs is taken simultaneously, and patient's compliance is poor, and the collocation of the dosage of several drugs is not because the problem of formulation dosage and doctor's the degree of awareness often are optimized proportionings.In recent years, though the depressor of much new good effect few side effects is arranged, the controlling blood pressure compliance rate is relatively low.But drug combination can be used two or more depressor, and the dosage of every kind of medicine is little, and the therapeutical effect of medicine should have collaborative or the effect of addition at least, and its ill effect can be cancelled out each other or not overlapping at least or addition.Medicine kind number used during drug combination is too much unsuitable, and crossing to have complicated drug interaction at most.Therefore, select to merge very difficulty of medication amount and kind, need a large amount of development tests.
Therefore, a kind of new treatment pattern is applied to clinical gradually, and the compound hypertension medicine preparation is internationally recognized a kind of orientation treatment.Because the compound antihypertensive drug prescription is followed the principle that different mechanism of action medicines carry out proportioning usually, therefore show as the advantage that increases curative effect or reduce side effect, obtained better controlling of blood pressure effect.
Summary of the invention:
The object of the present invention is to provide a kind of side effect little, taking convenience can effectively be treated the compound preparation of three kinds of antihypertensive drugs of hypertensive combination, and this compound preparation is controlling blood pressure effectively.
Purpose of the present invention is implemented by following technical scheme: a kind ofly treat the compound preparation that hypertension contains trandolapril, it includes following composition: Levamlodipine (Levamlodipine) or Levamlodipine officinal salt, hydrochlorothiazide (hydrochlorothiazide), trandolapril (trandolapril) or its officinal salt are Main Ingredients and Appearance, being equipped with pharmaceutically suitable carrier forms, in wherein every preparation unit, described Levamlodipine (Levamlodipine) or Levamlodipine officinal salt, count 2.5-10.0mg with Levamlodipine, described trandolapril (trandolapril) or its officinal salt, count 0.5-4.0mg with trandolapril, described hydrochlorothiazide (hydrochlorothiazide) is 6.25-25.0mg.
It is a kind of that to treat the compound preparation that hypertension contains trandolapril be capsule, soft capsule, granule, tablet, powder, slow releasing agent or injection dosage form.
Advantage of the present invention: be to give full play to the complementary mechanism of action of medicine according to drug combination to increase curative effect, up to standard fast, make the blood pressure compliance rate reach 82%, reduce with a certain dosage and increase relevant untoward reaction.Compound formulation of the present invention has instant effect, blood pressure compliance rate height, and side effect is little, the characteristics that cost is low.
The specific embodiment:
Further set forth medicine of the present invention by the following examples, these embodiment are only presented for purposes of illustration, do not limit the scope of the invention.
Embodiment 1-4 is listed as follows:
Use the conventional method in the pharmaceuticals industry among the embodiment, the according to the form below formulation becomes tablet, makes the used pharmaceutically suitable carrier of tablet--and adjuvant is the conventional adjuvant of this area.Wherein the proportioning of its Main Ingredients and Appearance is as follows:
Embodiment |
Count (mg/ sheet) with Levamlodipine |
In trandolapril (mg/ sheet) |
Hydrochlorothiazide (mg/ sheet) |
1 |
Levamlodipine 2.5 |
Trandolapril 0.5 |
Hydrochlorothiazide 6.25 |
2 |
Levamlodipine 2.5 |
Trandolapril 4.0 |
Hydrochlorothiazide 25.0 |
3 |
Levamlodipine 5.0 |
Trandolapril 2.0 |
Hydrochlorothiazide 12.5 |
4 |
Levamlodipine 10.0 |
Trandolapril 4.0 |
Hydrochlorothiazide 12.5 |
Use the conventional method in the pharmaceuticals industry simultaneously among the embodiment, can also be prepared into capsule, soft capsule, granule, powder, controlled release agent or injection dosage form,, pharmaceutically suitable carrier--used adjuvant is the conventional adjuvant of this area of this dosage form.
Embodiment 5: the present invention treats hypertensive compound preparation clinical trial:
To illustrate that pharmaceutical composition of the present invention is to hypertensive therapeutical effect by the human body pharmacodynamic experiment below.
1, physical data:
Clinical 400 routine hypertension philtrums, age 40--50 year, 150 examples; Age 51--60 year, 150 examples, age 61--70 year, 100 examples.
2, diagnostic criteria: according to " Chinese hypertension prevention and control guide ", hypertension is defined as: do not obey under the antihypertensive situation systolic pressure 〉=140mmHg and/or diastolic pressure 〉=90mmHg.
3, Therapeutic Method:, adopt randomized to be divided into 4 groups, every group of this compound formulation medicine that adopts embodiment of the invention 1-4 gained respectively with 400 routine hypertensive patients, make tablet, every day is once oral, according to the dose difference of tablet, each a slice or two took 6 days.
4, efficacy assessment standard:
Draft according to " Chinese hypertension prevention and control guide ".The target of antihypertensive therapy is blood pressure to be returned to " normally " or " ideal " level.40-60 year patient be depressurized to ideal or normal arterial pressure (≤130/85mmHg), 60-70 year patient be depressurized at least normal high value (≤140/90mmHg).
5, therapeutic outcome: administration begins to carry out respectively in the 1st day, 2 days, 3 days, 4 days, 5 days, 6 days blood pressure determination.The result shows that medication is after 6 days, 4 groups of the embodiment of the invention are totally 400 routine hypertension philtrums, and it is up to standard to amount to 330 routine patient's blood pressures, promptly returns to " normally " or " ideal " level, mean blood pressure compliance rate 82% illustrates that the present embodiment compound medicine has good curing hypertension effect.
Curative effect sees the following form:
Case load |
Blood pressure case sum up to standard |
The below standard case sum of blood pressure |
The mean blood pressure compliance rate |
400 |
330 |
70 |
82% |
Discuss
This product is the compound formulation that brings high blood pressure down, and is applicable to treatment hypertension, and its blood pressure compliance rate is higher.
