11. An intranasal device for administration of a pharmaceutical composition comprising:
a reservoir and a means for discharging one or more doses of the pharmaceutical composition, wherein the reservoir contains a quantity of the pharmaceutical composition;
wherein the pharmaceutical composition is a spray-dried powder comprising:
epinephrine or a pharmaceutically acceptable salt thereof, wherein the pharmaceutical composition provides a dose of about 0.5 mg to about 8 mg of the epinephrine or the pharmaceutically acceptable salt thereof, wherein a median particle diameter of the epinephrine or the pharmaceutically acceptable salt thereof is about 20 μm to about 75 μm;
sodium chloride, wherein the pharmaceutical composition comprises about 0.01 mg to about 5 mg of the sodium chloride;
polysorbate 80, wherein the pharmaceutical composition comprises about 0.01% w/v to about 2% w/v of the polysorbate 80; and
a carrier, wherein the carrier includes mannitol, a cyclodextrin, citric acid, lactose, and/or sodium carboxymethylcellulose;
wherein the pharmaceutical composition does not include an alpha-adrenergic blocker;
wherein the pharmaceutical composition does not include a preservative; and
wherein the intranasal device further includes a nasal probe, a ball, an actuator, and a piston.
12. The intranasal device of claim 1 , wherein the intranasal device has 360° functionality and is constructed and configured to dispense a dose from any position.
13. The intranasal device of claim 11 , wherein the intranasal device further includes a sensor that is adapted to detect a displacement or a deformation of a portion of the intranasal device when the spray-dried powder is dispensed from the reservoir.
