Description
Technical field
The invention belongs to field of pharmaceutical preparations, relate to a kind of Alprostadil lipid complexes and injection micelle composition thereof.More particularly, the present invention relates to a kind of entrapment efficiency that improves, reduce zest, but Entkeimung and can stablize the Alprostadil lipid complexes of storage and its injection micelle composition of injection micelle composition and preparation method thereof.
Background technology
Alprostadil (PGE
1), have another name called prostaglandin E
1It is the extremely strong endogenous biological active substances of a kind of activity, pharmacological actions such as tangible expansion periphery and arteria coronaria blood vessel, anticoagulant, the formation of inhibition tremulous pulse medicated porridge sample lipid speckle are arranged, be used for the treatment of myocardial infarction, thrombophlebitis, atherosclerosis obliterans, the limbs chronic ulcer due to chronic arteria occlusion disease such as thromboangiitis obliterans, the atherosis disease of chronic arterial, extremity tranquillization pain due to the blood capillary circulatory disturbance also can be used for the thromboembolism preventing treatment of blood vessel transplantation postoperative.Alprostadil is a white, needle-shaped crystals, and is easily molten in ethanol, slightly soluble in the water.At present domestic existing how tame pharmaceutical manufacturer production injection Alprostadil, but Alprostadil is very unstable in water, easily degrades, and the quite a few untoward reaction of Alprostadil in addition makes its pharmacologically active be difficult to normal performance.
Cholesterol is a kind of neutral lipid, also belong to parents' molecule, but lipophile is better than hydrophilic, and there is certain similarity in the structure of its structure and cholic acid, shown in chemical formula,
The cholic acid cholesterol
Can form a hydrophilic radical after the cholesterol molecule derived and become amphiphatic molecule, its amphoterisation method is with the salify of deriving of the hydroxyl in the molecule, can be made into sulfate, phosphate and sulfonate etc. usually.The cholesterol salt that forms after this process is derived has nontoxic, non-irritating characteristics, exist certain similarity with cholate on the structure, in water the cholesterol molecule of some drug molecules and amphoterisation by lipotropy part hydrophobic force and may be also polarity affinity by hydrophilic parts, and form polymolecular complex according to certain molecule mole ratio.This complex has following characteristics:
1. formed this complex evenly and stably is scattered in the aqueous medium with colloidal form, can concentrate arbitrarily within the specific limits, is suitable as the carrier of high dose medicament.
2. because the cholesterol molecule and the drug molecule of amphoterisation combine with certain mole ratio, covered the structure of drug molecule, drug molecule contacts with the direct of tissue when having avoided drug administration by injection, can solve the zest problem of medicine.
3. the particle diameter of this complex generally below 100nm, accepted by the patient easily for slightly opalescent clear and bright solution by outward appearance, and because the complex particle diameter is little, but filtration sterilization has guaranteed the safety of administrated by injection.
4. under proper condition, the cholesterol molecule of amphoterisation can disperse in aqueous medium automatically with medicine, need not special handling, and preparation process is simple, and preparation is with low cost.
5. has good physical and chemical stability.
The preparation technology of Alprostadil lipid complexes that this law provides and injection micelle composition thereof is simple, and preparation is with low cost, and stability is stronger, and medicine is difficult for dissociating out from composite system, is expected to solve the zest of medicine in the injection site.Cholesterol sulfate and analog thereof also can produce the commissure effect with hydrophilic head and two hydrophobic afterbodys of phospholipid, increase the drug loading of Alprostadil.

1) an auricular vein tube wall of respectively drawing materials of left ear negative control (sodium chloride injection) is complete, and blood vessel does not have obvious expansion.Clear, the no swelling of endotheliocyte, necrosis, the obvious inflammatory cell infiltration of tube wall and Guan Zhouwu is not seen pathological changes such as thrombosis in the tube wall.See accompanying drawing 2.
2) auris dextra positive control (injection Alprostadil) group respectively draw materials a blood vessel obviously expansion be " ++ ", endotheliocytic swelling, necrosis are " ++ ", see that thrombosis is " ++ ", the hemorrhage and inflammatory cell infiltration of tube wall and Guan Zhoujian is " +++".See accompanying drawing 3.
3) an auricular vein tube wall of respectively drawing materials of auris dextra Alprostadil lipid complexes and injection micelle composition group thereof is complete, and blood vessel does not have obvious expansion.Do not see pathological changes such as thrombosis in the tube chamber.Alprostadil lipid complexes and the morphology of injection micelle composition group thereof are significantly better than commercially available injection Alprostadil group, no obvious irritation.See accompanying drawing 4.
Result of the test shows that Alprostadil lipid complexes and injection micelle composition thereof are not seen the obvious stimulation effect to tame rabbit ear vein blood vessel.
(2) hemolytic test
Get tame Sanguis Leporis seu oryctolagi 10mL, place the centrifuge tube that scribbles heparin, the centrifugal 5min of 4000rpm, discard upper plasma, with hemocyte repeatedly with normal saline 10mL flushing, the centrifugal supernatant of removing in each flushing back, till supernatant does not take on a red color, draw a certain amount of erythrocyte then, the red blood cell suspension of dilution preparation by volume 2%, 4 ℃ of refrigerator and cooled are hidden standby.Recording mode:
"---" coagulation: haemolysis not, but it is agglomerating red blood cell condensation to occur, can separate again after rocking.
"-" be haemolysis not: erythrocyte all sinks, and the upper strata is faint yellow muddy slightly solution.
"+" part haemolysis: solution is faint yellow or light red, and the test tube bottom has a small amount of erythrocyte residual.
" ++ " haemolysis: solution takes on a red color, and the no erythrocyte in test tube bottom is residual.
Table 2 hemolytic result of the test
The result shows that made Alprostadil lipid complexes injection micelle composition solution does not cause erythrocytic hemolytic reaction, meets intravenous standard.
(3) sensitivity test
The result shows that made Alprostadil lipid complexes injection micelle composition solution does not cause the Cavia porcellus anaphylaxis, meets intravenous standard.
