ABSTRACT:
A method of forming droplets comprises flowing a liquid through a channel; spreading the liquid into a thin film in the channel; and impinging the thin film with a flowing gas to atomize the liquid into droplets. The droplets may then be dried to produce dried particles, such as particles comprising a pharmaceutical active agent. The droplets formed by the disclosed process have improved size and/or size distribution characteristics.
