Description
Technical field
The present invention relates to the hypertensive CV-4093 oral preparation of quick releasing of treatment and the method for preparing of a kind of disintegrate rapidly, release, comprise oral instant-dissolving tablet, oral cavity disintegration tablet, dispersible tablet.
Background technology
Hypertension is one of modal cardiovascular disease in the world today.Epidemiological study shows that there are hyperpietic 600,000,000 people in the whole world at present, and the hypertension prevalence is about 10%, and more American-European developed countries are 20%.Recent statistics result according to health ministry announcement on October 12nd, 2004 shows that China 18 years old and above resident's hypertension prevalence are 18.8%, estimate national number of patients more than 1.6 hundred million.Compared with 1991, prevalence rises 31%, and number of patients increases about more than 7,000 ten thousand people.The rural area prevalence rises rapidly, and the town and country gap is not obvious.Big city, small and medium-sized cities, one to four type of rural area hypertension prevalence are followed successively by 20.4%, 18.8%, 21.0%, 19.0%, 20.2% and 12.6%.In the huge hyperpietic crowd of China's quantity, the hypertension awareness is 30.2% in addition, and treatment rate is 24.7%, and control rate is merely 6.1%; With 26.6%, 12.2% compare with 2.9% and to increase in 1991, but still be in relatively poor level.Hypertension is the important risk factor that causes apoplexy, coronary heart disease and renal failure, and in clinical trial, the apoplexy that antihypertensive therapy on average can reduce 35-40% takes place, the myocardial infarction of 20-25% and surpass 50% heart failure.This shows that the research antihypertensive agent is our vital task, and market potential is very huge.
CV-4093 is a dihydropyridine class calcium channel blocker; Can block L passage on the vascular smooth muscle; Suppress flow of calcium ions; Vasodilator smooth muscle and produce hypotensive effect has no negative inotropic action, does not accelerate heart rate, advantage such as extra natriuretic diuretic effect, renal function protecting, increase insulin sensitivity.Hypotensive effect is remarkable, and the good blood pressure lowering paddy/p-ratio of having taken medicine once a day is used to treat each phase hypertension; Especially with the patient of kidney disease; Patient's antihypertensive effect to low renin and low blood calcium level is more obvious, and can improve uric acid metabolism, to the hyperpietic with renal failure; Single with or unite use with α, beta-blocker, can obtain the effect of being satisfied with.Patient for hypertensive patients type ii diabetes patient or carbohydrate tolerance reduction also has good hypotensive effect.
Tablet is one of present most widely used oral dosage form, and it has takes and store and transport convenient and the stable advantage of medicine.But often, disintegrate and medicine stripping fully absorb because of slowly influencing medicine; Simultaneously, when dosage is big and need once take medicine more for a long time, often make troubles for the patient of old man, child and dysphagia.In this case, oral solution, suspensoid and Emulsion etc. are comparatively superior, but liquid preparation have again medicine stability relatively poor with shortcoming such as storing inconvenience etc.For the advantage that combines tablet and liquid preparation and avoid its shortcoming, over nearly 20 years, get final product the dissolved oral preparation of quick releasing of rapid disintegrate after having developed chance water abroad; Major part can be dissolved rapidly after oral preparation of quick releasing was met saliva, became solution state, and mouthfeel is good; No grittiness; Taking convenience, rapid-action, bioavailability is high, patient bad for old man, child and function of deglutition and water intaking inconvenience provides convenience, so oral preparation of quick releasing more and more receives patient's welcome with its unique advantages.
The successful exploitation of CV-4093 oral preparation of quick releasing; With the compliance that improves the hypertensive patient greatly, can be for hypertensive patient's housecoat usefulness below the state of emergency, onset is rapid; Absorb fully; Also lay the foundation in the exploitation and the listing of China,, will produce good economic benefits and social benefit in case put on market for new oral formulation-oral preparation of quick releasing.The CV-4093 oral preparation of quick releasing of our development can satisfy old man on the market and other swallows the patient's who takes inconvenience medication requirement.
