Definitions

  • the present disclosure belongs to the field of medicine, and relates to a pharmaceutical composition that can be delivered by a metered dose inhaler and a preparation method.
  • Inhaled formulations have the advantages of rapid onset of action, low doses, and few systemic side effects.
  • An inhaler is a device known to deliver an active agent to a patient's respiratory tract.
  • Various inhaler systems are already commercially available. Obtained, three common inhalers are dry powder inhalers, nebulizers, and metered dose inhalers (MDIs).
  • MDIs metered dose inhalers
  • MDIs can be used to deliver drugs in dissolved or suspended form. When activated, MDIs can propel active agent-containing aerosol droplets into the respiratory tract through a relatively high vapor pressure propellant, whereas dry powder inhalers typically rely on the patient's Inspiratory action draws the drug in dry powder form into the respiratory tract. Active agents delivered by MDI are typically dispersed in the propellant in particulate form, and in order to form fine particles, the active agent is typically micronized. Active agent fine particles suspended in a propellant have a tendency to rapidly aggregate or flocculate, and aggregation or flocculation of these fine particles may result in a tendency to complicate the delivery of the active agent.
  • agglomeration or flocculation can lead to mechanical failures, such as may be caused by blockage of the valve opening of the inhaler container; agglomeration or flocculation of drug particles can also lead to rapid deposition or thickening of drug particles, which may lead to Dose delivery is inconsistent, which is especially troublesome for high potency, low dose drugs.
  • Another problem associated with such suspension MDI formulations is crystal growth during drug storage, which can lead to a decrease in inhaler performance and uniformity of MDI dose delivered over time.
  • WO2010138862 discloses a co-suspension that can be delivered by a metered dose inhaler, in which particulate phospholipid particles are used as a carrier to maintain the suspension

技术领域technical field
本公开属于医药领域,涉及一种可通过定量吸入器递送的药物组合物以及制备方法。The present disclosure belongs to the field of medicine, and relates to a pharmaceutical composition that can be delivered by a metered dose inhaler and a preparation method.
背景技术Background technique
吸入制剂具有起效迅速、用药量低、全身副作用小等优势,吸入器是一种已知可以将活性剂递送到患者呼吸道的装置,已有多种不同的吸入器***已经可以通过商业渠道购买获得,三种常见的吸入器为干粉吸入器、喷雾器以及定量吸入器(MDI)。Inhaled formulations have the advantages of rapid onset of action, low doses, and few systemic side effects. An inhaler is a device known to deliver an active agent to a patient's respiratory tract. Various inhaler systems are already commercially available. Obtained, three common inhalers are dry powder inhalers, nebulizers, and metered dose inhalers (MDIs).
MDI可用于递送溶解或悬浮形式的药物,当被启动时,MDI可以通过相对较高蒸汽压的推进剂将含有活性剂的气溶胶液滴推送到呼吸道,而干粉吸入器则通常依赖于患者的吸气作用将干粉形式的药物吸入到呼吸道。通过MDI递送的活性剂通常以微粒形式分散在推进剂中,为了形成微细粒子,通常将活性剂进行微粒化处理。悬浮在推进剂中的活性剂微细粒子具有快速聚集或絮凝的趋势,这些微细粒子的聚集或絮凝可能导致活性剂的递送趋向复杂化。例如,聚集或絮凝可导致机械故障,比如可能会因为吸入器容器的阀口堵塞而引起各种故障;药物颗粒的聚集或絮凝也可以导致药物颗粒的快速沉积或凝稠,这些行为可能会导致剂量递送不一致,这对于高效力的低剂量药物而言尤其麻烦。跟此类悬浮MDI制剂相关的另一问题是,药物贮存期间的晶体生长,这会导致吸入器性能以及MDI递送剂量的均匀性随着时间 而下降。MDIs can be used to deliver drugs in dissolved or suspended form. When activated, MDIs can propel active agent-containing aerosol droplets into the respiratory tract through a relatively high vapor pressure propellant, whereas dry powder inhalers typically rely on the patient's Inspiratory action draws the drug in dry powder form into the respiratory tract. Active agents delivered by MDI are typically dispersed in the propellant in particulate form, and in order to form fine particles, the active agent is typically micronized. Active agent fine particles suspended in a propellant have a tendency to rapidly aggregate or flocculate, and aggregation or flocculation of these fine particles may result in a tendency to complicate the delivery of the active agent. For example, agglomeration or flocculation can lead to mechanical failures, such as may be caused by blockage of the valve opening of the inhaler container; agglomeration or flocculation of drug particles can also lead to rapid deposition or thickening of drug particles, which may lead to Dose delivery is inconsistent, which is especially troublesome for high potency, low dose drugs. Another problem associated with such suspension MDI formulations is crystal growth during drug storage, which can lead to a decrease in inhaler performance and uniformity of MDI dose delivered over time.
一种改善MDI稳定性及递送性能的方式是引入载体颗粒,例如,WO2010138862公开了一种可通过定量吸入器递送的共悬浮液,其中使用了微粒状的磷脂颗粒作为载体,以维持混悬液的稳定性;但其载体颗粒的用量过高,致使单位剂量的载药量较小,单位时间内需要多次给药才可发挥药效。One way to improve the stability and delivery performance of MDI is to introduce carrier particles, for example, WO2010138862 discloses a co-suspension that can be delivered by a metered dose inhaler, in which particulate phospholipid particles are used as a carrier to maintain the suspension However, the dosage of its carrier particles is too high, resulting in a small amount of drug loading per unit dose, and multiple administrations are required per unit time to exert its efficacy.
