A process and a nebulizer for dispensing a consecutively dose of a medicament in the form of a mist comprising: an energy source (ES) an air containing volume an air outlet fluidly connected to the air containing volume an air actuator adapted to release a flow of compressed air through the air outlet at such time as a predetermined ES pressure has been reached in the volume and at least two valve means in communication with the air actuator. The compressed air is released at a predetermined pressure of about 20 to about 100 psig. The valve means controls the actuation of the air actuator such that when a medication is nebulized a mist distribution of a medication is formed having droplets size in the range of approximately 1µ to approximately 7µ which inhaled by a user at a set of predetermined intervals.
