Nebulizer characteristics

Droplet size is a key factor in effective pulmonary
delivery of the drug through this route.
The droplet size is typically controlled through the
orifice diameter of the baffle, pressure of the gas,
and the density, concentration, viscosity, surface
tension, and flow rate of the drug solution.
