Definitions

  • the invention belongs to the field of pharmaceutical preparations, and in particular relates to a slow-release drug delivery system for small molecule drugs.
  • Injectable sustained-release preparations are one of the current research hotspots of pharmaceutical preparations, which aim to provide a drug reservoir, which can be used for subcutaneous injection, intramuscular injection, intramuscular injection, local injection and other administration methods.
  • local injection refers to local administration, such as injection in the spinal cavity, joint cavity, wound, eye, etc., and the drug can exert its effect locally after the drug is slowly released.
  • Injectable sustained-release preparations have many advantages, for example: the preparation can be directly injected into the desired administration site for slow drug release, reducing systemic toxicity and increasing therapeutic effect; secondly, the preparation can also reduce the number of administrations and improve patient compliance; In addition, the preparation can significantly reduce the cost of treatment.
  • this type of preparation also has some disadvantages, for example: since the drug is released over a long period of time and usually cannot be withdrawn after administration, good preparation stability is required. In addition, it is necessary to pay attention to whether the sustained-release preparation will cause a burst release effect, or produce other adverse effects such as diffusion and toxicity at the injection site.
  • sustained-release technology for injectables mainly includes oil sustained-release systems, polymer-based and lipid-based sustained-release systems, etc.
  • Patent 201310022657.3 discloses an analgesic sustained-release drug delivery system composed of an analgesic, drug vehicle, and drug sustained-release agent.
  • the drug sustained-release agent is liquid oil. Due to the low viscosity of the oil sustained-release system and the diffusion of organic solvents in the body, it may cause a burst release phenomenon, which has potential safety hazards. In addition, its release is relatively fast, which cannot meet the release requirements of some drugs.
  • Polymer sustained-release systems are mainly polylactic acid (PLA), poly(lactic-co-glycolic acid) (PLGA) and polyorthoester (POE).
  • Patent document US200303156A1 provides a slow-release microsphere composition and a preparation method thereof.

  • Patents CN103705442, CN103705439 and CN102933200 all contain water in different proportions, which may have stability problems such as easy oxidation and low viscosity, so they can only be administered by subcutaneous injection.
  • sustained-release systems that have been approved or are currently under research have problems such as complex preparation process, difficult degradation of sustained-release carriers, and safety caused by burst release.
  • the lipid-based sustained-release systems under research or on the market all have low viscosity and cannot meet the problem of incisional drug delivery.

Abstract

本发明涉及一种药物组合物,包含药学上的活性成分、甘油、缓释载体和药学上可接受的溶剂。所述药物组合物刺激性小,具有良好的缓释性能,用药安全性及耐受性,且在常温下为高粘度液体,特别有利于灌注给药。

Description

一种小分子药物缓释递药系统
本申请要求享有申请人于2021年8月27日向中国国家知识产权局提交的,专利申请号为202110997613.7,发明名称为“一种小分子药物缓释递药系统”的在先申请的优先权。该在先申请的全文通过引用的方式结合于本申请中。
技术领域
本发明属于药物制剂领域,具体涉及一种小分子药物缓释递药系统。
背景技术
可注射用缓释制剂是目前药物制剂的研究热点之一,其旨在提供一种药物贮库,可用于皮下注射、肌内注射、肌肉注射、局部注射等给药方式。其中,局部注射是指在局部给药,如在脊椎腔、关节腔、伤口、眼内等部位注射,药物缓慢释放后可在局部发挥作用的给药方式。
可注射用缓释制剂具有多种优势,例如:该制剂可以直接注入期望给药部位缓慢释药,降低系统毒性,增加治疗效果;其次,该制剂还可以减少给药次数,提高患者顺应性;此外,该制剂还可显著降低治疗费用。但是,此类制剂同样存在一些缺点,例如:由于药物在较长时间内释放,且用药后通常不能撤回,因此需要具有良好的制剂稳定性。并且,需要关注缓释制剂是否会引起突释效应,或者在注射部位产生弥散、毒性等其他不利影响。
近年来,可注射用缓释技术的研究主要包括油缓释体系、以聚合物和脂质为基质的缓释体系等。
油缓释体系主要以可注射用植物油和有机溶剂为主,专利201310022657.3公开了一种由镇痛剂、药物溶媒、药物缓释剂组成的镇痛缓释递药系统,其中药物缓释剂为液体油。由于油缓释体系粘度较低同时有机溶剂在体内扩散,可能引起突释现象,存在安全性隐患,此外其释放较快,无法满足一些药物的释放需求。
聚合物缓释体系主要为聚乳酸(PLA)、聚乳酸-羟基乙酸共聚物(PLGA)和聚原酸酯(POE)等。专利文献US200303156A1提供了一种缓释微球组合物及其制备方法,所述组合物包含聚合物PLGA、活性物质利培酮或9-羟基利培酮及其他赋形剂。2003年FDA批准了Janssen Pharmaceuticals开发的一种以PLGA为缓释载体的利培酮长效微球,商品名为RISPERDAL
Figure PCTCN2022115027-appb-000001
该缓释微球可提供14天持续释放。Heron Therapeutics Inc在专利文献CN106535886A中公开了以聚原酸酯为缓释载体,含有酰胺类局麻药,烯 醇类非甾体抗炎药和聚原酸酯的组合物及其制备方法。目前已获得欧盟批准,商品名为
Figure PCTCN2022115027-appb-000002
由于高分子材料在给药部位降解缓慢,因此存在安全性风险。
以脂质为基质的缓释体系主要为脂质复合物和脂质体。PACIRA开发了一种长效布比卡因多囊脂质体混悬注射液,商品名为
Figure PCTCN2022115027-appb-000003
用于治疗术后疼痛及神经阻滞,镇痛效果可持续24小时。该脂质体中主要含有二芥酰基卵磷脂(DEPC)和二棕榈酰磷脂酰甘油(DPPG)两种合成磷脂,将布比卡因包裹在多囊脂质体中能起到缓释作用。但是,多囊脂质体制备工艺复杂,且对储藏条件要求高。此外,专利CN103705442公开了一种原位脂质凝胶制剂,其特征在于所述制剂包含磷脂、治疗有效量的活性物质和溶剂;所述磷脂优选为大豆磷脂、蛋黄卵磷脂中的一种或几种,更优选为大豆磷脂;所述的溶剂中含有有机溶剂,优选为无水乙醇、苯甲醇、叔丁醇、甘油中的一种或几种,同时含有水或生理性的水性介质。专利CN103705439公开了一种脂质凝胶制剂,其特征在于所述制剂包含PEG化的磷脂、非PEG化的磷脂、治疗有效量的活性物质和溶剂,这种脂质凝胶制剂中以水或生理性的水性介质作为溶剂,不含有胆固醇。CN102933200公开了单相凝胶组合物,所述组合物包含:20%~80%重量比的一种或多种磷脂;0.1%~70%重量比的水,其中采用高剪切、高能量或高压均质机使所述磷脂的粒径小于100nm以及所述凝胶组合物能通过25GX1/2英寸长的针头并以2cc/min的挤出速率且由不超过12磅的作用力从1cc注射器中挤出,并且所述组合物还任选地包含药理学活性剂。专利CN103705442、CN103705439和CN102933200均含有不同比例水,可能存在易氧化等稳定性问题,同时粘度较低,只能皮下注射给药。
目前已批准或在研的缓释体系存在制备工艺复杂,缓释载体较难降解,突释引起的安全性等问题。此外,在研或上市的以脂质为基质的缓释体系均存在粘度低,无法满足切口给药的问题。因此,亟需开发一种适于药用,稳定性、安全性、耐受性和/或缓释性能得到改善,高粘度的缓释制剂系统。
