A mutual prodrug of a corticosteroid and a substituted phenylphosphate (β-agonist derivative) for formulation for delivery by aerosolization to inhibit pulmonary inflammation and bronchoconstriction is described. The mutual prodrug is preferably formulated in a small volume solution (10-500 μL) dissolved in a quarter normal saline having pH between 5.0 and 7.0 for the treatment of respiratory tract inflammation and bronchoconstriction by an aerosol having mass median average diameter predominantly between 1 to 5μ, produced by nebulization or by dry powder inhaler.
本文描述了一种皮质类固醇和取代苯基磷酸酯(β-激动剂衍生物)的相互前药,用于制剂通过气溶胶化途径送达,以抑制肺部炎症和支气管收缩。该相互前药最好以小体积溶液(10-500μL)的形式制剂,溶于pH在5.0至7.0之间的四分之一的生理盐水中,通过雾化或干粉吸入器产生主要介于1至5μ之间的质量平均直径的气溶胶治疗呼吸道炎症和支气管收缩。
