• a. at least one vial enclosing the volume Vsub [ml or mg] of said at least one substance;
• said at least one vial having at least one fluid inlet port having an inlet diameter Din [mm] and at least one fluid discharging outlet port having an outlet diameter Dout [mm], configured for placement in proximity to said body cavity of the subject;
• and
• b. an activation mechanism comprising a base, the activation mechanism adapted to, upon actuation, to release said at least one substance within said body cavity in the form of an aerosol;
• wherein the fluid discharging outlet port is structured such that the aerosol forms a bi-modal spray pattern having a first pattern and a second pattern, the first pattern having a plume angle in a range of 5°±4° and the second pattern having a plume angle in a range of 35°±10°;
• wherein said at least one substance is either (i) Topiramate;
