Abstract
A dripping pill of clopidogrel is prepared from clopidogrel and polyoxyvinyl monostearate through proportional mixing, heating until the mixture is fused, stirring and dripping it in condensing liquid.
Description
[technical field] the present invention relates to a kind of medicine and preparation method thereof, particularly Chlorpirgray drop balls and preparation method thereof.
[background technology]
Drop pill splashes in the immiscible condensed fluid after being meant solid or liquid medicine and substrate heat fused mixing, and condensation is shunk and the preparation made.Because medicine is with superfine microparticulate, and the one-tenth colloid disperses in solution, and becomes rapid dissolved amorphous mixture, can improve the drug oral bioavailability effectively.The Rue oil. drop pill of China with regard to going on the market in 1971 makes dropping pill formulation really become a kind of effective pharmaceutical dosage form.Drop pill can also can be made into sustained-release preparation for for oral administration, external and local the use, has brought into play and continued playing an important role in China's field of pharmaceutical preparations, is a kind of noticeable and the dosage form of good development prospect arranged.
Dropping pill formulation has the multiple advantage that is different from other peroral dosage forms, by selecting water-soluble base for use, control drug release rate or dissolve scattered time limit, can under the condition of quenching, form solid dispersion, medicine exists with atomic little microgranule, crystallite or molecularity, so can improve the dissolution rate and the bioavailability of insoluble drug, play quick-acting, effect efficiently; Select for use suitable controlled slowly releasing adjuncts or enteric solubility substrate to drip and make ball, can control the release of medicine, play the effect of slow release or enteric.Particularly, when its sustained-release preparation of preparation, can consider drops, thereby can in control drug release, increase bioavailability for some insoluble drugs or drugs with low bioavailability.The production equipment of dropping pill formulation is simple, processing ease, and weight differential is little, and production cost is low, and no dust is suitable for industrialized great production.Also facile hydrolysis, oxidation decomposition or volatile pharmaceutical pack can be embedded in wherein and increase stability of drug.
According to its preparation technology's difference, dropping pill formulation can be divided into quick-acting efficient drop pill, controlled release pill, enteric coated drop pill, coated drop pill, external-use drops, hard capsule drop pill, elaioplast drop ball etc.Used substrate is except fat-soluble substrate (as stearic acid, glyceryl monostearate, insect wax, hydrogenated vegetable oil, stearyl alcohol, spermol, semi-synthetic fatty acid ester etc.) and water-soluble base (as Polyethylene Glycol, sodium stearate, glycerin gelatine, carbamide, poloxamer etc.) commonly used, in recent years, there are some good polymeric materials to be developed substrate again as drop pill, and the more and more important effect of performance.Polyoxyethylene stearate 40 esters are a kind of nonionic surfactant, be usually used in preparing insoluble drug, solid dispersion as griseofulvin, tolbutamide and nalidixan etc., it has similar average molecular mass to PEG2000, and S-40 can promote dispersion, disintegrate, the stripping of medicine in solid dispersion and the effect that makes medicament solubilization.Along with being on the increase of substrate kind, preparation technology's is ripe day by day perfect, and drop pill is extensive day by day in the application of Chinese-western medicine preparation, therefore existing medicine is carried out modified form, produce more medicinal dropping ball dosage form, will greatly enrich drug market, improve quality of medical care.
Clopidogrel is a kind of safety of extensive use clinically and orally active antithrombotic reagent.It produces the anticoagulant effect by optionally suppressing combining and the activation of the glycoprotein GPlllb/llla complex of the ADP mediation of secondary of adenosine diphosphate (ADP) (ADP) and platelet receptor.Clopidogrel must could suppress hematoblastic gathering through biotransformation, and prodrug forms 2-oxygen base-clopidogrel by Oxidation, and then forms active metabolite through hydrolysis.This active metabolite of in-vitro separation shows that it can irreversiblely rapidly combine with platelet receptor, thus anticoagulant.But also do not isolate the active metabolite that produces this effect.Except that ADP, clopidogrel can also suppress the platelet aggregation of other agonist induction by blocking-up by the platelet activation that the ADP that discharges causes.Clopidogrel can not suppress the activity of phosphodiesterase, but it plays a role by irreversibly modifying platelet ADP receptor, and therefore, the regeneration rate of platelet normal function is relevant with hematoblastic renewal rate.Clopidogrel was applicable to apoplexy, the myocardial infarction of outbreak in the recent period and made a definite diagnosis the patient of peripheral arterial disease.This medicine can reduce atherosclerotic incident such as myocardium infarction, the incidence rate of apoplexy and vascular death.
The clopidogrel dosage form of using clinically is tablet and capsule at present.Dropping pill formulation has characteristics such as bioavailability height, release fast, quick produce effects, is made into drop pill, in the hope of reaching the raising bioavailability, brings into play curative effect of medication more fully, reduces purposes such as untoward reaction.
