6. The intranasal device of claim 1 , wherein the pharmaceutical composition further comprises a catechol-o-methyl transferase (COMT) inhibitor.
7. The intranasal device of claim 1 , wherein the pharmaceutical composition further comprises one or more agents selected from a group consisting of a mucosal permeation or penetration enhancer, a mucoadhesive, a mucosal transit slowing agent, a mucosal transport enhancer, or any combination thereof.
8. 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.
9. The intranasal device of claim 1 , wherein the intranasal device further includes an intranasal device global positioning system (GPS) device or is coupled to a GPS device, wherein the intranasal device GPS or the GPS device is constructed and configured to provide location data.
10. The intranasal device of claim 1 , wherein the intranasal device further includes a communications interface, wherein the communications interface is constructed and configured to transmit data wirelessly to at least one remote device.
11. The intranasal device of claim 1 , wherein the carrier includes mannitol, a cyclodextrin, citric acid, lactose, and/or sodium carboxymethylcellulose.
12. The intranasal device of claim 1 , wherein the pharmaceutical composition does not include a preservative.
13. The intranasal device of claim 1 , wherein the quantity of the pharmaceutical composition is between about 5 mg and about 75 mg.
14. The intranasal device of claim 1 , 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 dry powder is dispensed from the reservoir.
15. The intranasal device of claim 14 , wherein the intranasal device further includes a display and a power supply, a timer, a clock, and/or a printed circuit board, wherein the display is constructed and configured to display a time of dose dispensation.
16. A kit for intranasal administration of a pharmaceutical composition comprising:
at least one intranasal device, wherein each of the at least one intranasal device includes 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; and
a pouch and/or a hard case, wherein the at least one intranasal device is enclosed in the pouch and/or the hard case;
wherein the pharmaceutical composition is a dry powder comprising:
epinephrine or a pharmaceutically acceptable salt thereof, wherein the pharmaceutical composition provides a dose of about 0.01 mg to about 10 mg of the epinephrine or the pharmaceutically acceptable salt thereof;
a non-sulfite stabilizer, wherein the pharmaceutical composition comprises about 0.01% w/v to about 5% w/v of the non-sulfite stabilizer; and
a carrier; and
wherein the pharmaceutical composition does not include an alpha-adrenergic blocker.
17. The kit of claim 16 , wherein the hard case includes a desiccant plastic.
18. The kit of claim 16 , wherein the pouch and/or the hard case is water resistant or waterproof.
19. The kit of claim 16 , wherein the pouch and/or the hard case is Modular Lightweight Load-carrying Equipment (MOLLE)-compatible.
20. 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 0.01 mg to about 10 mg of the epinephrine or the pharmaceutically acceptable salt thereof,
a non-sulfite stabilizer, wherein the pharmaceutical composition comprises about 0.01% w/v to about 2% w/v of the non-sulfite stabilizer; and
a carrier; and
wherein the pharmaceutical composition does not include an alpha-adrenergic blocker.
