Abstract
Intranasal delivery devices include dosage forms containing medical compositions for use in the intranasal devices, and methods of delivering medical compositions to the nasal mucosa of users. The devices dispense a predetermined quantity of fluid into the nasal passage of a user, in which the predetermined quantity of fluid is contained in, or produced in a dosage form or blister that is crushed by a plunger with sufficient force to drive the dosage form against a piercing mechanism, piercing the dosage form and forcing the liquid contents from the dosage form and through a delivery channel into a spray to be directed into the nasal passage of a user. The plunger is connected to a trigger device by a linkage that confers a mechanical advantage to the trigger mechanism.
