Abstract
The present invention relates to the injection of Batifeiban and pharmaceutically-acceptable salts thereof, and prepare and pharmaceutical applications.Result shows, and this injection has good stability and safety in production and Clinical practice.
Description
Technical field
The present invention relates to the injection field for the treatment of thrombotic disease, the injection field of the Batifeiban particularly containing treatment thrombotic disease effective ingredient.
Background technology
Coronary heart disease refers to because of coronary artery being obstructed and the blood supply insufficiency caused and myocardial ischemic heart disease in various degree.Coronary heart disease is western countries always, especially the No.1 fatal disease of the U.S..In the U.S., nearly 1,550,000 people's morbidities every year.But cardiovascular morbidity and the mortality rate of developing country rise year by year.Percutaneous coronary intervention (pci) (PercutaneousCornonaryIntervention, PCI) is main effectively one for the treatment of means that arteria coronaria blocks.But in PCI art or postoperative at PCI, the acute coronary thrombosis caused by platelet aggregation, to block be main again, normally fatal adverse events.
The Drug therapy of patients with coronary heart disease, it is the most frequently used that aspirin adds clopidogrel, but aspirin adds clopidogrel can only suppress part platelet aggregation, GPIIb/IIIa antagonist action be the last passage of platelet activation, can more effectively reduce in PCI art or postoperative thrombotic ischemic complications.While PCI operation, medicine is prevented in application antiplatelet glycoprotein receptor GPIIb/IIIa (α IIb β 3), can effectively reduce the probability of blocking generation again.
Abciximab (Reopro), tirofiban (Tirofiban, trade name Aggrastatt), eptifibatide (Eptifibatide, trade name Integrilin) common feature be block GPIIb/IIIa be combined with part Fibrinogen, and reach anticoagulant, be widely used in coronary heart disease, comprise unstable angina pectoris, acute coronary syndrome and PCI.Although these three kinds of medicines have the function suppressing GPIIb/IIIa and its ligand binding jointly, but biochemical characteristic, clinical practice are variant: abciximab goes through to be applied to PCI, tirofiban is used for unstable angina pectoris, and eptifibatide can be used for PCI and unstable angina pectoris.Clinical research shows the probability that platelet glycoprotein receptor antagonist effectively can reduce the complication after intracavity coronary artery procedure and myocardial infarction death and occurs.
Tirofiban and eptifibatide can special suppression GPIIb/IIIa and its ligand bindings, and abciximab can not only suppress GPIIb/IIIa, the information transmission of suppression blood vessel endothelium and smooth muscle cell integrin receptor α v β 3 simultaneously.Block relevant receptor because abciximab can act on two simultaneously to arteria coronaria, on clinical effectiveness, demonstrate superiority.But abciximab is human mouse chimeric antibody, although its immunogenicity reduces a lot, but after all and inhuman source or humanized antibody, in clinical practice, find that abciximab still causes the immunoreation of anti-mouse antibody many patients, cause thrombocytopenia (Thrombocytopenia).Abciximab long half time, even if hemorrhage reaction drug withdrawal immediately, can not stop its untoward reaction after occurring immediately.To transfuse blood salvage pathway unique often.And small-molecule peptide, generally there is no antigenicity, can reuse; And the general half-life is short, if any hemorrhage reaction, just can stop hemorrhage after drug withdrawal.Therefore, be necessary the medicine of the anti-GPIIb/IIIa researching and developing a new generation, it is made to possess following characteristics: very high affinity can be had to GPIIb/IIIa (integrin IIb3), stop platelet aggregation, the integrin v3 (its subunit the same) close with GPIIb/IIIa can be suppressed again, to suppress the growth of vascular smooth muscle, arteries is suppressed to block further again; This inhibitor should not have antigenicity, can reuse; And the half-life is short, once drug withdrawal, can the advantage such as Bleeding control reaction.
Batifeiban belongs to the antiplatelet glycoprotein receptor repressor of a new generation, more existing (go on the market abroad, or bibliographical information) other antiplatelet acceptor compound, there is a lot of significantly advantage and characteristic.Batifeiban peptide is not only strong to the affinity of platelet glycoprotein receptor GPIIb/IIIa target spot, can anticoagulant, also suppresses vascular smooth muscle to grow by suppressing glass-based albumen Vitronectin receptor.
Injection is the direct intravasation of intravenous fluid especially, without absorption process, bioavailability is high, onset is rapid, and (main adverse reaction of Batifeiban is symptom, sign and laboratory abnormalities caused by platelet aggregation reduces: bleeding episode as various in prolonged bleeding time, hematuria etc. can to stop administration at any time according to the state of an illness, need to stop administration immediately after there is untoward reaction, otherwise more serious untoward reaction can be caused), be widely used clinical.At present, although Batifeiban possesses some special knowledge as active constituents of medicine, but because of the restriction of Batifeiban dissolubility: can only be soluble in 0.1mol/L hydrochloric acid solution, slightly soluble in methanol, ethanol, ethyl acetate and 50% acetonitrile, almost insoluble in water, acetone, ether and 0.1mol/L sodium hydroxide solution, be difficult to by injection routine prescription the preparation being prepared into applicable medicinal requirements.
Sodium citrate is anticoagulant, main use is (blood for blood transfusion) anticoagulation in vitro, its pharmacological action principle is: calcium is required material in coagulation process, thrombokinase (thromboplastin) can be promoted, thrombin and fibrinous formation, and activate intra platelet free calcium thrombin reaction etc.In citric acid radical ion and blood calcium ion generate be difficult to resolve from soluble complexes calcium citrate, this complex is soluble in water but not easily dissociate, and calcium ion in blood is reduced, and coagulation process is suppressed, thus stops blood coagulation.Sodium citrate is prepared into blood transfusion sodium citrate injection, i.e. 2.35%-2.65% sodium citrate (C
