Abstract

The invention relates to aerosolized and humidified particles comprising a therapeutically active substance which can be obtained by suspending dry inhalable particles in a carrier gas, adding water vapor and causing condensation of water on the particles. The invention further relates to methods to generate these particles, and apparatus useful to carry out such methods.
