Steroidy wziewne podawane z nebulizatorów siateczkowych – co powinniśmy wiedzieć?

Inhalation therapy with nebulized steroids (e.g. budesonide) ispossible only if inhaled aerosol droplets contain micronized solidparticles of the active ingredient. Since both aerosol droplets andbudesonide particles have comparable sizes (micrometer-range), itis essential to prove that drug particles are indeed present in theaerosol released from the nebulizer. This work presents data of thestudy focused on the particle size of budesonide in several drugproducts. Particle size determination was done in liquids sampleddirectly from nebulizers (mesh and pneumatic type) during theirnormal operation. It was found that at such conditions the majori-ty of budesonide particles in all tested drugs (Benodil, BudixonNeb, Nebbud, Pulmicort) are smaller than 3-4 μm. Since the ave-rage diameter of droplets (D50, MMAD) in the aerosol releasedfrom studied nebulizers is in the range of 5-6 μm, the results con-firm that in all tested cases the aerosol should contain a similaramount of steroid particles. Small differences in budesonide par-ticle and aerosol droplet size distributions which were found in va-rious nebulizer-drug combinations are unimportant for the predic-ted penetration of aerosolized drugs to the respiratory system.
