Kandegaasita pihusti, meetod kandegaasita aerosoolide valmistamiseks, kasutamine

摘要

Preparation of aerosols for inhalative application of biologically active macromolecules (I) (especially peptides), from an aerosol preparation which contains (I), comprises: (a) measuring a dosage amount of (I) in a measuring chamber in a nebuliser which is free of propellant gases; and (b) spraying (I) to inhalable droplets (with a particle size less than 10 mu m) within 1-2 seconds. Spraying is carried out at a pressure of 100-500 bar through a nozzle with a hydraulic diameter of 1-12 mu m. Also claimed is an aqueous aerosol composition for inhalative administration of (I), which contains 3-100 mg of (I) per ml.
