The method and system according to preferred embodiments of the present invention allows optimizing the dispensing of aerosol medicaments. In particular the system according to a preferred embodiment of the present invention allows the administration of an exogenous pulmonary surfactant to very young patients (e.g. preterm neonates). A catheter 101 conveys atomized surfactant directly to the retro-pharyngeal region in order to increase efficiency of the medicament administration without being invasive: this is particularly important for very young patients, such as pre-term born neonates suffering from neonatal Respiratory Distress Syndrome (nRDS). According to a preferred embodiment of the present invention the catheter is made of biocompatible flexible material (e.g. plastic material). It is possible to couple the catheter with a rigid scaffolding (e.g. metallic) to increase stiffness of the device and to improve easiness of positioning operations. In a preferred embodiment of the present invention the delivery of the atomized medicament is done by means of an air blasting technique.根據本發明之較佳具體實例的方法及系統使得噴霧藥劑的分配最佳化。特定言之，根據本發明之一較佳具體實例的系統提供向極年輕患者(例如早產新生兒)投予外源性肺部表面活性劑。導管101將霧化之表面活性劑直接傳送至咽後區以在不侵入之情況下提高該藥劑投予之效率：此對於極年輕患者，諸如罹患新生兒呼吸窘迫症候群(nRDS)的早產新生兒而言尤其重要。根據本發明之一較佳具體實例，該導管由生物相容性可撓性材料(例如塑膠材料)製成。將該導管與剛性骨架(例如金屬)耦接以提高該裝置之硬度且提高定位操作之容易度為可能的。在本發明之一較佳具體實例中，藉助於鼓風技術進行該霧化之藥劑的傳遞。
