Description
Technical field
The present invention relates to a kind of butyrate clevidipine Emulsion and preparation method thereof.
Background technology
Hypertensive emergency refers to that blood pressure steeply rises caused severe clinical signs." the Chinese high blood of revision in 2005
Pressure guideline of prevention and treatment " in point out that hypertensive emergency is that blood pressure seriously raises, more than 180/120mmhg, and the progressive target organ that occurs together
Insufficient performance.Perioperative Hypertension is also included in hypertensive emergency esc/esh Europe Hypertension Guideline within 2007.
Show according to U.S.'s epidemiologic data, because hypertensive crises are come in the patient that emergency treatment is gone to a doctor, 1/3 is hypertensive emergency.In China
In hyperpietic, about 5% can occur hypertensive emergency.According to documents and materials, the incidence rate of hypertensive emergency target organ damage: brain
Disease 16.3%, intracranial or subarachnoid hemorrhage 4.5%, cerebral infarction 24.5%, acute heart failure, pulmonary edema 36.8%, cardiac muscle stalk
Extremely/angina pectoriss 12%, eclamposia 4.5%, dissection of aorta 2%, seriously threaten the life of patient.
Therapeutic Principle for the patient of hypertensive emergency is should to enter ICW, continues to monitor blood pressure and as early as possible
Apply suitable antihypertensive drugs.Need to alleviate in a short time the state of an illness, the progressive injury of prevention target organ, reduce cardiovascular event
And mortality rate.With often needing intravenous infusion antihypertensive drugs, blood pressure can be made to be dropped rapidly to level of security, again can not be excessive or too fast
Blood pressure lowering, to avoid the occurrence of locally or systemically hypoperfusion (especially kidney, brain or coronary ischemia).Clinically it is used for controlling at present
In the medicine of critically ill patient blood pressure processed, one kind can not taken into account blood vessel and select rapid-onset in system, infusion process, rapid knot
The medicine of bundle and no intravenous injection toxicity requirements.Therefore, develop a kind of medicine that can reduce rapidly simultaneously precise control blood pressure
Thing preparation is significant.
Butyrate clevidipine (clevidipine butyrate), chemical entitled 4- (2,3- Dichlorobenzene base)-Isosorbide-5-Nitrae-dihydro-
2,6- dimethyl-3,5-dipicolinic acid methyl (1- oxobutoxy) methyl ester, its structural formula is as follows:
Butyrate clevidipine belongs to dihydrogen pyridine derivative, is a kind of calcium channel blocker used for intravenous injection of ultrashort effect,
There is the blood vessel of height and myocardium selectivity, rapid metabolization is inert matter in vivo.It is rapid-action, and effect eliminates also soon,
Can ascending-dose precise control blood pressure.It is different from current many antihypertensive drug through kidney and (or) hepatic metabolism for the intravenous injection,
Its metabolism in blood and tissue, thus do not accumulate in vivo.Butyrate clevidipine is almost insoluble in water, but has certain journey
That spends is fat-soluble.Therefore suitably it is prepared into the liquid emulsion for intravenous administration.Except insoluble drugs, Emulsion can be delivered
Decomposition susceptible to hydrolysis, can prevent medicine and plastic applicators used during intravenous injection tool adhesion, reduce office during transfusion
Portion's toxicity., in August in 2008 approval butyrate clevidipine Emulsion listing on the 1st, it is invalid to be administered orally for treatment or be administered orally for fda
Hypertension it can also be used to treatment surgical site infections acute blood pressure raise.
Because Emulsion is thermodynamic unstable system, and wherein important component oil phase and emulsifying agent have the oxidizable, Yishui River
The characteristic of solution.The butyrate clevidipine injectable emulsion of listing needs cold preservation under cryogenic, and the temperature in storage process becomes
Changing (as refrigeration-room temperature-cold preservation) easily causes the gathering of emulsion droplet to merge, and particle diameter increases, or even it is existing local breakdown of emulsion oil slick etc.
As.The stability of Emulsion has become the key factor of restriction drug loaded emulsion clinical practice.
Therefore, still in the urgent need to providing a kind of butyrate clevidipine that can solve the problem that above-mentioned technological deficiency to produce in prior art
Product are so as to can take into account quick acting, precise control blood pressure, reduce the needs such as untoward reaction simultaneously, and have higher storage
