Pharmaceutical formulations are described for use in the treatment of pulmonary arterial hypertension (PAH). The formulations comprise polymeric nanoparticles encapsulated within crosslinked polymeric hydrogel microparticles, wherein the polymeric nanoparticles carry a therapeutic agent suitable for treatment of PAH loaded within them (for example, prostacyclin synthetic analogs, PPAR β agonists and NO donors). Preferred formulations are inhalable, dry powder pharmaceutical formulations, which are able to swell on administration to the lungs of a patient.
本文描述了用于治疗肺动脉高压(PAH)的药物制剂。这些制剂包括封装在交联聚合物
水凝胶微颗粒内的聚合物纳米颗粒,其中聚合物纳米颗粒内含有适合治疗 PAH 的治疗剂(例如,
前列环素合成类似物、
PPAR β 激动剂和 NO 给药剂)。首选的制剂是可吸入的干粉药物制剂,这种制剂在进入患者肺部后能够膨胀。
